Hi, I am a Javascript apprentice. Can you help me with my project?
- Sure! What do you need?
Oh, it’s very simple, I just want to make a static webpage that shows a clock with the real time.
- Wait, why static? Why not dynamic?
I don’t know, I guess it’ll be easier.
- Well, maybe, but that’s boring, and if that’s boring you are not going to put in time, and if you’re not going to put in time, it’s going to be harder; so it’s better to start with something harder in order to make it easier.
You know that doesn’t make sense right?
- When you learn Javascript you’ll get it.
Okay, so I want to parse this date first to make the clock be universal for all the regions.
- You’re not going to do that by yourself right? You know what they say, don’t repeat yourself!
But it’s just two lines.
- Don’t reinvent the wheel!
Literally, Javascript has a built in library for t...
- One component per file!
I’m lost.
- It happens, and you’ll get lost managing your files as well. You should use Webpack or Browserify for managing your modules.
Doesn’t Javascript include that already?
- Yes, but some people still have previous versions of ECMAScript, so it wouldn’t be compatible.
What’s ECMAScript?
- Javascript
Why is it called ECMAScript then?
- It’s called both ways. Anyways, after you install Webpack to manage your modules, you still need a module and dependency manager, such as bower, or node package manager or yarn.
What does that have to do with my page?
- So you can install AngularJS.
What’s AngularJS?
- A Javascript framework that allows you to do complex stuff easily, such as two way data binding!
Oh, that’s great, so if I modify one sentence on a part of the page, it will automatically refresh the other part of the page which is related to the first one and viceversa?
- Exactly! Except two way data binding is not recommended, since you don’t want child components to edit the parent components of your app.
Then why make two way data binding in the first place?
- It’s backed up by Google. You just don’t get it do you?
I have installed AngularJS now, but it seems I have to redefine something called a... directive?
- AngularJS is old now, you should start using Angular, aka Angular 2.
But it’s the same name... wtf! Only 3 minutes have passed since we started talking, how are they in Angular 2 already?
- You mean 3.
2.
- 3.
4?
- 5.
6?
- Exactly.
Okay, I now know Angular 6.0, and use a component based architecture using only a one way data binding, I have read and started using the Design Patterns already described to solve my problem without reinventing the wheel using libraries such as lodash and D3 for a world map visualization of my clock as well as moment to parse the dates correctly. I also used ECMAScript 6 with Babel to secure backwards compatibility.
- That’s good.
Really?
- Yes, except you didn’t concatenate your html into templates that can be under a super Javascript file which can, then, be concatenated along all your Javascript files and finally be minimized in order to reduce latency. And automate all that process using Gulp while testing every single unit of your code using Jasmine or protractor or just the Angular built in unit tester.
I did.
- But did you use TypeScript?37 -
We have a new developer working in our office. He is fairly new, which is understandable, so he asks for help regularly(which I actually appreciate). This time however, he asked for help, and every step of the way argued it. He said he needed help making a small circle(it's just an indicator on a table).
I told him if there is a mat-icon it would be simple, but if not it would still be pretty simple with CSS. He argued that those two options seem messy. I pointed out they are extremely clean actually, and showed him how it was only about 4 lines of css. and 1 if there was a material icon. He agreed it was pretty easy, and then went with a complicated way to have green or red. I let him know that was really trivial, and even gave him the exact code he needed for it(at this point, he could have copy and pasted, adjusted the conditional to the name of his variable, and be done).
He proceeds to take 3 more days to complete this task, making a new component for a colored circle, using templates and nested css in the html, and hard coding the color as opposed to using the material colors we use site wide. All in all 100+ lines of code. And he felt my solution with fewer than 10 lines was messy.14 -
I forgot what it felt like to not be the domain expert in a thing. 😅 Have to learn a ton of new things for work, which is great, but I feel guilty for being so slow. SO SLOW.
I know it’s normal, I’m just…. Getting used to it. 😉
Anyway, here’s a cat.

The overhead on my JS projects is killing me. Today, I went to implement a simple feature on a project I haven't touched in a few weeks. I wasted 80% of my time on mindless setup crap.
- "Ooh, a simple new feature to implement. Let's get crackin'!"
- update 1st party lib
- ....hmm, better update node modules
- and Typescript typings while I'm at it
- "ugh yeah," revert one node module to outdated version because of that one weird proxy bug
- remove dead tsd references
- fix TS "errors" generated by new typings
- fix bug in 1st party lib
- clean up some files because the linter is nagging me
- pee
- change 6 lines of code <-- the work
- commit!3 -
That moment you realise Typescript is not called Typescript because it has types but because of the immense amount of typing you have to do to get anything done...

Just got given my own internal project at the company I work for! Basically I created a gulp task for one of our projects that allows us to use version control with Salesforce in a pretty easy way and deploy without a stupid IDE (like eclipse) getting in the way. Now they want me to turn that idea into a node module we can use company wide!5

What do you call it when you type a script? A TypeScript. Then you spill coffee on it...
now it's a JavaScript.4 -
Overheating The Javascript Ecosystem
Paranoid thought: You know, in the course of every day, being the corrupt piece of shit that I am, whenever I see a scandal or what looks like shenanigans-in-the-making, I ask myself
"Wisecrack, is this a fucking scam or con of some sort?"
I was recently asking myself this about javascript.
Not the language per se, but the ecosystem.
I noticed how there are a thousand CLIs for simple shit. Another four thousand for page long libraries, for simpleton level shit (because prototypes are designed after satans own aborted love-child of object models). I noticed another eight thousand guys imitating steve jobs, talking at conferences and 'change the world' high-on-huffing-my-own-shit TEDX talks like rubyists that don't realize the world has moved on, all to hawk books and inflate CVs for cushy positions at major tech firms and the herd of dicksuckers following the next fad off a cliff like lemmings. And another eight thousand 'tech journalists' pushing them off the cliff while begging for outrage and hype dollars and slowly circling like vultures above the drain that is the ad-based economy.
And I thought to myself.
"Wisecrack, who benefits from all this noisy self-indulgent horseshit? Where is all the money coming from for all these books, conferences, meetings, publications, media, bread, and circuses?"
"I don't know wisecrack. But if I were the CEO of a big company, threatened by the prospect of a universal language, or universal platform, like flash, but one I couldn't kill like flash, I would try to do the most corrupt thing I could think of."
"Whats that wisecrack?"
"I would try to 'overheat' the ecosystem by selectively hiring people from that ecosystem, pumping money into a boatload of similar products, all in the hopes of provoking the equivalent of an immune overreaction, imitators all flooding the ecosystem with the same shit in different packages, self promoting sycophants, aggrenadizing social media idiots, tools sold as tools, hyped as 'the next coming of steve jobs', overcooked shit that focuses on ceremony over functionality, ritual over productivity, documentation over innovation like some sort of amazonion infinite nesting doll hellscape of documents linking to documents linking to documents, each one a new circle of dantes inferno, where the definition of anything links to another document that says "see also xyz", and I would convince them that they had done it to themselves."
And then I would push typescript as their lord, savior, and master. "
"How do you know all this wisecrack?"
"Because I am a piece of shit, and, this is what I would do in any executive's shoes."11 -
Completed Angular 2 course on codeschool, really liked improvements and simplicity of Angular over Angularjs. Decided to do quick start guide in official website. Oh my f**king god... I need to setup webpack, typescript linter, typings, polyfills etc angular2-cli is no better, crawling with errors... why... why can't one just start a project and work instead spending loads of timing configuring all of that... AND WHY WE CANT HAVE PROPER SUPPORT FOR LATEST FEATURES...
I don't even know what I am ranting about... I just wish to spend more time creating things than configuring for ages development environment.7 -
You hired me to be a JavaScript developer. Just because you have stock inMicrosoft is not a good reason to try stuffing Typescript down my throat. Maybe you should have hired a Typescript developer!6

Ever heard of event-based programming? Nope? Well, here we are.
This is a software design pattern that revolves around controlling and defining state and behaviour. It has a temporal component (the code can rewind to a previous point in time), and is perfectly suited for writing state machines.
I think I could use some peer-review on this idea.
Here's the original spec for a full language: https://gist.github.com/voodooattac...
(which I found to be completely unnecessary, since I just implemented this pattern in plain TypeScript with no extra dependencies. See attached image for how TS code looks like).
The fact that it transcends language barriers if implemented as a library instead of a full language means less complexity in the face of adaptation.
Moving on, I was reviewing the idea again today when I discovered an amazing fact: because this is based on gene expression, and since DNA is recombinant, any state machine code built using this pattern is also recombinant[1]. Meaning you can mix and match condition bodies (as you would mix complete genes) in any program and it would exhibit the functionality you picked or added.
You can literally add behaviour from a program (for example, an NPC) to another by copying and pasting new code from a file to another. Assuming there aren't any conflicts in variable names between the two, and that the variables (for example `state.health` and `state.mood`) mean the same thing to both programs.
If you combine two unrelated programs (a server and a desktop application, for example) then assuming there are no variables clashing, your new program will work as a desktop application and as a server at the same time.
I plan to publish the TypeScript reference implementation/library to npm and GitHub once it has all basic functionality, along with an article describing this and how it all works.
I wish I had a good academic background now, because I think this is worthy of a spec/research paper. Unfortunately, I don't have any connections in academia. (If you're interested in writing a paper about this, please let me know)
Edit: here's the current preliminary code: https://gist.github.com/voodooattac...

When defining a range, let's say from 1 to 3, I expect:
[1, 2, 3]
Yet most range functions I come across, e.g. lodash, will do:
_.range(1, 3)
=> [1, 2]
And their definition will say: "Creates an array of numbers ... progressing from start up to, but not including, end."
Yet why the fuck not including end? What don't I understand about the concept of a frigging range that you won't include the end?
The only thing I can come up with that's this is related to the array's-indexes-start with-0-thing and someone did not want to substract `-1` when preparing a for loop over an 10 items array with range(0,10), even though they do not want a range of 0 to 10, they want a range from 0 to 9. (And they should not use a for loop here to begin with but a foreach construct anyway.)
So the length of your array does not match the final index of your array.
Bohhoo.
Yet now we can have ranges with very weird steps, and now you always have to consider your proper maximum, leading to code like:
var start = 10;
var max = 50;
var step = 10;
_.range(start, max + step, step)
=> [10, 20, 30, 40, 50]
and during code review this would scream "bug!" in my face.
And it's not only lodash doing that, but also python and dart.
Except php. Php's range is inclusive. Good job php.4 -
Me in school: Math? When do I need know those details? I can look them up and just code it.
Me in high school: Computer science is way too math-y. I want to code!
Me coding php: Just make it work.
Me coding typescript: Just make it work.
Me coding scala: Just make it ... what ... how do I make it work!?!
Me asking stackoverflow: How do I do X in scala some functional programming stuff in mind in order to keep immutability.
Somebody way smarter than I: "In scalaz, a function A => A is called an endomorphism and is a Monoid whose associative binary operation is function composition and whose identity is the identity function"
Me now: Fuck my old arrogant self.1 -
While reviewing a PR from one of our newer FE devs, I ended up spending more time than I would like mulling over its composition. The work was acceptable for the most part; the code worked. The part that got me was the heavy usage of options objects.
When encountering the options object pattern (or anti-pattern, at times) in complex scenarios, I have to resist the urge to stop whatever I'm doing and convert it to the builder pattern/smack them in the head with a software design manual. As much as I would like to, code janitor is one of the least valuable activities I engage in daily, and consistently telling someone to go back to the drawing board for work that is functional, but not excellent is a great way to kill morale. Usually, I'll add a note on the PR, approve it, add a brown bag or two on that sort of thing, and make attendance mandatory for repeat slackers. Skills building and catharsis all rolled up in a tiny ball of investing in your people.
Builders make things so much cleaner; they inform users what actions are available in a context; they tend to be immutable, and when done well, provide an intuitive fluent interface for configuration that removes the guesswork. As a bonus, they're naturally compositional, so you can pass it around and accumulate data and only execute the heavy lifting bits when you need to. As a bonus, with typescript, the boilerplate is generally reduced as well, even without any code generation. And they're not just a dumping ground for whatever shit someone was too lazy to figure out how to integrate into the API neatly.
They're more work in js-land, sure; you can't annotate @builder like with Lombok, but they're generally not all that much work and friendlier to use.

You've got to be a masochist to be a javascript/typescript developer.
Each time I come back to the npm-related parts of my project, the application won't start because of some dependencies nonsense. And I know for sure I left the project working perfectly last time.
Every time... every fucking time! Just leave the project unattended for a week and be sure you'll find it dead next time.
I mean I as a developer don't really have to do ANYTHING for my code to break.
How can people love javascript is a mystery to me.16 -
At work, my closest relation is with the DBA. Dude is a genius when it comes to proper database management as well as having a very high level of understanding concerning server administration, how he got that good at that I have no clue, he just says that he likes to fuck around with servers, Linux in particular although he also knows a lot about Windows servers.
Thing is, the dude used to work as a dev way back when VB pre VB.NET was all the rage and has been generating different small tools for his team of analysts(I used to be a part of his team) to use with only him maintaining them. He mentioned how he did not like how Microsoft just said fk u to VB6 developers, but that he was happy as long as he could use VB. He relearned how to do most of the GUI stuff he was used to do with VB6 into VB.NEt and all was good with the world. I have seen his code, proper OOP practices and architectural decisions, etc etc. Nothing to complain about his code, seems easy enough to extend, properly documented as well.
Then he got with me in order to figure out how to breach the gap between building GUI applications into web form, so that we could just host those apps in one of our servers and his users go from there, boy was he not prepared to see the amount of fuckery that we do in the web development world. Last time my dude touched web development there was still Classic ASP with JScript and VBScript(we actually had the same employer at one point in the past in which I had to deal with said technology, not bad, but definitely not something I recommend for the current state of web development) and decided that the closest thing to what he was used was either PHP(which he did not enjoy, no problem with that really, he just didn't click with the language) and WebForms using VB.NET, which he also did not like on account of them basically being on support mode since Microsoft is really pushing for people to adopt dotnet core.
After came ASP.NET with MVC, now, he did like it, but still had that lil bug in his head that told him that sticking to core was probably a better idea since he was just starting, why not start with the newest and greatest? Then in hit(both of us actually) that to this day Microsoft still not has command line templates for building web applications in .net core using VB.NET. I thought it was weird, so I decided to look into. Turns out, that without using Razor, you can actually build Web APIs with VB.NET just fine if you just convert a C# template into VB.NET, the process was...err....tricky, and not something we would want to do for other projects, with that in we decided to look into Microsoft's reasons to not have VB.NET. We discovered how Microsoft is not keeping the same language features between both languages, having crown C# as the language of choice for everything Microsoft, to this point, it seems that Microsoft was much more focused in developing features for the excellent F# way more than it ever had for VB.NET at this point and that it was not a major strategy for them to adapt most of the .net core functionality inside of VB, we found articles when the very same Microsoft team stated of how they will be slowly adding the required support for VB and that on version 5 we would definitely have proper support for VB.NET ALTHOUGH they will not be adding any new development into the language.
Past experience with Microsoft seems to point at them getting more and more ready to completely drop the language, it does not matter how many people use it, they would still kill it :P I personally would rather keep it, or open source the language's features so that people can keep adding support to it(if they can of course) because of its historical significance rather than them just completely dropping the language. I prefer using C#, and most of my .net core applications use C#, its very similar to Java on a lot of things(although very much different in others) and I am fine with it being the main language. I just think that it sucks to leave such a large developer pool in the shadows with their preferred tool of choice and force them to use something else just like that.
My boy is currently looking at how I developed a sample api with validation, user management, mediatR and a custom project structure as well as a client side application using React and typescript swappable with another one built using Angular(i wanted to test the differences to see which one I prefer, React with Typescript is beautiful, would not want to use it without it) and he is hating every minute of it on account of how complex frontend development has become :V
Just wanted to vent a little about a non bothersome situation.8 -
I'm having such a blast writing code in TypeScript. Once you learn it you cannot go back to regular JavaScript.7

This whole Microsoft & GitHub thing is how it begins:
1) Embrace
oh it's really cool, Microsoft is adding some cool features we've been missing for a while, GitHub is still great
2) Extend
Alright, there's this new `msgit` that has some really cool features for rebasing and merge conflicts, I won't need to worry about fucking up my git history
3) Extinguish
`msgit` is not compatible with `git` and GitHub requires us to use it, but what can we do, all our code and build triggers are set up..
They are doing the same thing to JavaScript with TypeScript and stopped the development of the Internet for ~10 years...
I don't want to paint dark clouds, but I heard this theory at work and it makes sense that Ms would take it in a direction where people are locked in to their ecosystem. It won't happen immediately, but all signs point to this.

JavaScript is a rollercoaster. From "Golly hello world is easy and I can make webpages now", to "wtf '1'+1 is '11' kill me now", to "it's not be that bad if you know how to use it", to discovering typescript and it starts feeling like a real language.
... until you can't build the project because you have too many types so you blow the memory limit in node. I can up the limit, but I can't guarantee that we won't blow past this in the future. Browsing issues on the ts repo reveals that this has been a thing for years.

As I was refactoring a class in a TypeScript project, I changed calls from `this.config` to `this.getConfig()`.
Suddenly, the tests were failing as somehow the live credentials were used from within the test.
Digging deeper I discovered this.
interface Base {
public config;
public getConfig();
}
So far so good. Wondering why config needs to be public, though nothing too shabby, let's look further:
class MyImpl implements Base {
constructor() {
this.config = this.getConfig()
}
getConfig = () => someGlobalVar;
}
┻━┻︵ \(°□°)/ ︵ ┻━┻
Why would you do this? This breaks dependency injection completely.
In the tests, we were of course doing:
testMe = new MyImpl();
testMe.config = testConfig;
So even though you have a getter, you cannot call it safely as the global var would take precedence. It's rather used as a setter within the constructor. WTF.
Sad part is that this pattern is kept throughout the entire codebase. So yeah for consistency!?
(And yes, I found a quick workaround by doing
getConfig = () => this.config || someGlobalVar;
though still, who in their right mind would do something like this?)1 -

You have a JavaScript application. You have to keep up with stupid devs that don't know TypeScript because you don't have the time to let them study it and they get demotivated when they can't do stuff so fine, you keep it JS. You use JSDoc to write the documentation. You miss using TypeScript so you start doing some @typedef's. Oh your linter gets it and starts behaving as a substitute of TypeScript. You get excited and write more and more @typedef's! ... until they get so complicated that you start documenting *that*...3

I just wasted 2 hours trying to figure out why the properties of a destructured object returned undefined, even though everything was fine in JSON format.

Turns out I used the wrong property names to access the info inside each object.

const abc: string = 'Hi';
Can we take a moment to appreciate how retarded it is that TSlint throws a warning here that the string type is inferred and unnecessary.
I want to put the type there because it looks more readable. Code looks better if every variable has a type, irrespective of whether it's a constant. I know the fucking type is inferred you braggart linter bitch. What the fuck does it expect? A fucking award because it inferred that a string constant is of the fucking type string? How the ever loving fuck does that warrant a squiggly ass yellow warning line, reminiscent of that smartass 10 year old in class who has to yell out every answer when the teacher never asked a question.5 -

Hiii devRanters, I have a TypeScript question for you...
How do I dynamically import classes?
I have a class like this:
export default class Foo implements Bar {
...
....public getName(): string {
........return this.name;
....}
}
and then I have another file with this:
import(`./class-cmd/${file}`).then((command) => {
....winston.debug(command);
....winston.debug(command.getName());
});
the first command spits out something like this:
debug: default=class Foo {
....constructor() {
........this.name = "foo";
....}
....getName() {
........return this.name;
....}
}
and I would expect that the second command will work, however it throws this:
UnhandledPromiseRejectionWarning: TypeError: command.getName is not a function
Any idea what I might be doing wrong?18 -
Just came across a function with a typo (this is in TypeScript) - let's call the function slightlyComplicaedName - see the typo? t is missing. Wanted to refactor the function name to fix the typo. Next thing I know, the project doesn't compile anymore. There was already a function called slightlyComplicatedName in that file and it was doing something completely different.
I get that naming is hard, but using typos to differentiate between functions seems too much :)2 -
Dont worry what about what comes from naysayers. The Javascript/Typescript route is a great choice. Ive been trying to get away from node for years and back into a more sTeAdY side of things with C# or PHP but nope, as soon as anyone gets whiff that your generally great with JS, theres an offer on the table. The grass is green over here. It might be a bunch of 25 yr old hipsters eating it but its green.21

Typescript: All of your javascript code is valid typescript
Installs Typescript
runs typescript
Typescript: line x in function y has an error
Checking the function for error and the code is fine
After wasting an hour comment out all the linez in function y
Run typescript
Typescript: you have an error on line x which is commented in function y
ERROR IN A COMMENTED LINE :(4 -
We are starting a new project where we decieded to use node.js with express.js. It is quite exciting because we have previoisly use node.js only a little and me and my colleagues are eager to learn something new. As I was doing some research I came upon TypeScript. Do you guys think that it is worth spending more time learning TypeScript and use it in upcoming project?6
-
I mostly work in Java as a backend developer, but lately I started a frontend side project in Angular. Man, Typescript and SASS are awesome! Totally love it :)2
-
I knew AngularJS, just learnt Angular. Realized what typescript is and how amazing it is. I am a .Net guy so creating lambda functions in typescript made me excited lol. It's a little frustrating to write "imports" in every TS file though. Can now add ✔️Angular and ✔️typescript to my resume 😉. Starting with Vue.JS as soon as I am done playing with Angular.2
-
There's plenty of literature about how to emulate classes and interfaces flawlessly in JS even without es6, but no, let's make a separate language using 20 extra keywords and several unnecessary concepts called TypeScript with its own compiler.10
-
when TS does its job and team mates complaining that TS is too sensitive!
it does its job you douche, now you do yours!5 -
So today I told my boss “nodejs without typescript is like sex with strangers without a condom. Sure it’s fun and all... but then you get an std”12

Me, rueing typescript: "Dammit, Typescript!"
Typescript's cheeky response: Type 'string' is not assignable to type "Dammit"

I totally forgot how bad working with JavaScript is. After like a year of working with properly typed TypeScript base where navigation and documentation works very well, now I am in a world where IDE (IntelliJ IDEA) does very little, essentially it's just now a stupid editor. After few days I miss TypeScript already.
-
I started making a library to get to know TypeScript. 4 days into the commits and I don't know if I made the best choice or the worst choice. I MEAN WHY CLASSES!! JAVASCRIPT IS MORE A FUCNTIONAL PROGRAMMING LANGUAGE THAN AN IMPERATIVE PROGRAMMING LANGUAGE! I DONT WANT TO NEW UP! I DONT WANT THE DEVELOPERS TO NEW UP! WHERE ARE THE DESIGN PATTERNS! I CANT FUCKING FIND IT!!4
-
Why developer of c# (Anders Hejlsberg) when developing (TypeScript) not implemented method overloading and interfaces' methods implementation with same names.3
-
Context: New to typescript. Writing a thing, doing it for work, good opportunity to stretch my dev legs. Using a propriety lib, alternatives not an option.
Rant begin:
SOOOO, who the fuck thought THIS was a good idea:
1. Lib has minified react in dev (because closed source) meaning no downstream errors AND the entire premise of the lib is that a widget is a react component, so I'm writing typescript react the entire time without downstream errors
2. SHIT docs. By that, I mean there's an API reference page that's so sparse there's literally a set of CRUCIAL interfaces that only say the word 'Interface' on them. That's it. that's what i get. It's an interface. NO FUCKING SHIT SHERLOCK, what the fuck is it though? What's its purpose? Is it an interface for a dog? A dog that has a 'shit' property? or a cat? or a cat eating dog shit? Nobody fucking knows - the docs sure as fuck don't care.
3. No syntax highlighting - editors, IDEs (i've tried a few) can't even find the lib inside this environment, so Code and everything else thinks I'm importing shit that doesn't even exist - so no error prediction, code completion based on syntax of the library, none of that.
4. There are some EXTREMELY basic samples - these samples exclusively use React classes - no function components, no hooks, nada - just classes and even perfect replicas of the sample code display erratic behavior like errors about missing props, so that's mostly FUCKING USELESS
5. And this... this is where the straw breaks the fucking camel's back... there's no... there's no hot reloading... Do you know what that (in conjunction with the previous 4 fuckups) means?
When I write anything or I fuck up (which of course I'm doing every time I write half a line because how the fuck?) I have to restart the client and server EVERY FUCKING TIME and manually test to see if the error (THAT ONLY GETS REPORTED IN THE LOCAL UI) is gone or different.
Then, once I see the error, it isn't an error: it's the minified React error-decoder link and guess what? It isn't really clickable a link OR copyable, meaning that every FUCKING time I get a new error, I have to MANUALLY TYPE A FUCKING 50 CHAR URL TO FIND OUT A GENERIC REACT ERROR MESSAGE WITHOUT A LINE NUMBER OR ANY FUCKING CONTEXT. I HAVE TO DO THIS CONSTANTLY TO SEE IF ANYTHING I'M DOING EVEN WORKS.
6. There's no github to complain to the maintainers or search for issues because it's NOT FUCKING OPEN SOURCE so there is literally nothing to be fucking done about it.
This is due in a week and a half, found out about it last Friday. How's your day going?
PS: good to be back after a long respite from dev ranting.1 -
Why I hate typescript. Bored during quarantine so thought I rant a little more about this.
1. Compilation time, typescript increases project compilation time from 1 second to 3-4 seconds, which is basically triple or quadruple the time if you don't know math.
2. You write a minimum of 30% more code.
3. Many libraries are not written in TS by default, which means you end up having to manually install a fuckton of @types/(pckg name) manually which is incredibly shit.
4. Typescript is an absolute pain in the ass when using dynamic libraries. Plus when it works, it usually ends up finding maybe 1-2 errors in your code MAX, completely not worth it.
5.JSDoc is 100 times better. (Still don't use it though).
6. I actually enjoy loosely typed languages, having your compiler being smart enough to tell what the type of your input is is much better than it assuming you're a fucking retard so it forces you to manually type everything.
P.S if you hate loosely typed languages, kindly resort to Angular, C#, Java or whatever and leave JS alone, cunt.43 -
Do devranters think that Reason(ML) is too late to the game to compete against TypeScript...or can it ride React success to become more than a niche?
Personally I like it, but, like with F#, I don't enjoying the lack of resources every time I need to get something done.7 -
I'm a node JS developer, but I basically don't use Typescript but with the whole buzz around the technology, I feel I'm doing something wrong by not using Typescript and refusing to learn it. What do you think?4
-
I just got told that a codebase written in javascript / typescript can't be built to last.
This is the type of rediculous stuff us Web Devs have to put up with.10 -
I honestly treat JavaScript as a binary executable format nowadays. It's an output format for me.
I choose you, TypeScript.4 -
Discussing with the boss:
boss: < How is it going? >
me: < I'm trying to rewrite this horrible javascript code with typescript >
boss: < But release cannot support typescript >
me: < I can compile typescript locally and then release >
boss: < You are not listening to me! we can not execute a script in typescript >
me: < In fact we will use a script in javascript >
boss: < So why are you rewriting it in typescript? >
And so the discussion continued for another 20 minutes...8 -
It is about time we start thinking of real alternatives to JS in the browser.
What is wrong with TKinter on the web?
JavaFX? Even Windows Forms dude!
I am sick of the darn following:
- Webpack, Parcel
- React, Angular, Vue
- Typescript, babel
- Polyfills
- undefined
- COMPAFUCKINGBILITY!
- SPA VS. MPA
- SEO
- Maintainability
- BlaBla does not have a constructor
- <any>
I AM SICK OF WORKAROUNDS TO A ROOT PROBLEM WITHOUT BATTING AN EYE ABOUT THE ROOT PROBLEM!
LEARNING THE SHIT TON OF TOOLING FOR A MONTH BEFORE DOING ONE THING SHOULDN'T BE THE CASE! FUCK!29 -
I want to use Babel or Typescript for the first time. Because as I read it is the way to go, when compressing JavaScript and make it browser compatible. If that's false, please correct me.
There's a question I've got about this. Right now I am using a PHP router file dealing with requests and selecting the right .js file and compresses it. So I can write like modular JavaScript functions and include them when needed.
My question is, what do I have to change in my setup to switch to the mentioned technologies?11 -
Attempting a huge undertaking. I'm trying to convert a large JavaScript library, written in standard ES5 syntax, to Typescript with ES6 syntax. Turns out it's extremely difficult, but if I can finish this it will be 100% worth it3

Microsoft for creating typescript, and google for maintaining angular and forcing people to learn typescript before learning dog shit angular8

Fucking Visual Studio is such a piece of shit. 2 years ago we created a solution for our 7 webclients with 30 projects (clients, common stuff, tests, ...).
Things were ok, we could change something, save the file and everything was built and we just had to reload the client. Only F12 between the projects does not work.
But now the studio doesnt get shit done. Opening the clients solution after a clean checkout takes 5 minutes, saving doesnt build anymore, building breaks the project because it cant find references, rebuilding works but takes 3 minutes. When you have a syntactic error in a file the fucking thing almost crashes and becomes unresponse for a few seconds. It randomly shows errors in some files that disappear once you rebuilt it, sometimes it builds but still shows an error in that file.
But at least we will soon rewrite the clients in angular5 and dont need this piece of crap software anymore for the front end.
If I only could get my team to use another technology for the server so that I dont have to see this big pile of shit anymore. Fuck Visual Studio.2 -
Omfgggggggggggggggggggg
Fuck you typescript.
A whole day wasted working on react native pull to refresh bug, wondering why the fucking hell shit doesn't even appear when u try to pull. And so many other weird shit like touchable opacity not showing up.
Guess what was the problem? Fucking typescript importing shit from react-native-gesture-handler.
Btw I live and breathe typescript. I appreciate typescript everyday but for today fuck you typescript.3 -
Every time I try to use TypeScript for something, everything I learned a month ago is deprecated. Tsconfig keeps changing. The way to get and set up definition files has changed like 5 times now. From downloading, all the way to referencing. Can we please just settle on something now?1
-
It's kinda cute how people think strict typing is going to prevent bugs and make software reliable. It's all the rage now. I am not saying that there is anything wrong with strict typing but after all it was the original state of affairs and dynamically typed languages where developed to fix it.
Same hype with pure functional programming. It's going to push bugs out to the edges and make everything work. The pursuit of purity is no new thing and it breaks down on contact with the real world, such as a complex JSON. A switch to Haskell won't change that much. I have seen people hunt peculiar bugs in Haskell for ages.8 -
Started using typescript and other than the toxic wasteland that is NPM, I'm actually quite enjoying my time. Fuck javascript in the ass, typescript is like a nice dick pic to that ex who called to threaten your life for the third time that day. Different phone numbers every time too. Fuck JS.2
-
Did I screw up or is it ok doing this?
1. Calling another method inside the same factory file
2. Calling a method from another factory file
3. All factory methods are static because they only depend on their passed parameter(s)

Reading OpenSource lib that write in TypeScript is a nightmare
WTF:
export function concatMap<T, I, R>(
project: (value: T, index: number) => ObservableInput<I>,
resultSelector?: (outerValue: T, innerValue: I, outerIndex: number, innerIndex: number) => R
): OperatorFunction<T, I|R> {
return mergeMap(project, resultSelector, 1);
}
That is just fucking definition, no execution code inside1 -
Angular 2 is really, really satisfying me. Such a very clean and smart way to organize web functionality! And es2015 + typescript is sooo nice to work with.2

How do you feel about using TypeScript with React? I appreciate the benefits, but, as every snippet of React code everywhere on the web is vanilla JS,I just don't want the cognitive overhead.
Yes, I know TS is JS, but, if I'm not going to use the features, why bother? I'd want to strongly type props, state, etc.
What's the status of TypeScript support in the React ecosystem (eg Router, MUI, etc.)?
I'm kinda hoping Reason will get some traction as the type inference is much better, but, will that happen? Or is that going to fizzle so it's a choice between TS and JS?
Appreciate any thoughts on this---including those from anyone who's in the same boat.
Looking for views on TS in React ecosystem---no need to sell me on TS in general.6 -
I am some Kind of angry right now.
Some of you may know the App "Jodel" (for those who don't: it is an app which lets you talk to strangers at in your city/near your location)
I am in an informatics-Channel and I feel a bit annoyed.
There is a groundless hate against JavaScript or Java, it seems because... People feel cool? It remembers me of the PHP-Hate. Clueless people are talking shit, even if the web is not even their programming-field of activity.
Someone just said that in js you can do any shit and it works.
- you can leave out semicolons. wow.
Another one meant that one problem is the unlogical backwards-conpatibility. "You have to look if the script is running on the browsers and on your engine."
- Isn't that part of any programming language? To see if it works?
I don't know what to say right now.
#ilovejs
Uhm btw.: Can someone explain me, what he meant with "engine"? I mean there is an interpreter, but "engine"?!10 -

Omg nothing is as frustrating as writing tests for a given file, that is needed to achieve 100% code coverage. Also not following TDD.3

My colleagues want to forbid the usage of the shorthand constructor in TypeScript.
I feel strongly about this.
At least they find it annoying that I call the more verbose one "PHP-style constructor" :D -
Frontend JS devs - did you take the plunge into Typescript?
I've done some reading and a simple intro course but I'm still on the fence, what pushed you over the edge to adopt it?4 -
Typescript integration in Visual Studio SUCKS!! I waste so much time fucking trying to set up Angular 2 boilerplate that would take almost no time in VS Code or another editor because this bloated piece of garbage has to try and hack everything into MS build tasks and "Virtual Projects".
You would think that the company that created Typescript could figure out how to integrate it properly into their flagship IDE!!!
FUUUUCCCCCKKKKK!!1 -
Typescript is like a condom that has sideways with passages to flow the stuff ! Which is basically a bloody condom with hole ! WTF 😑 .ts to .js !
You just want whole bloody damn Java to be implemented at client side ..😣 God bless us .. Hate u Angular ... I loved you like hell now u hokkin up with this hoe ...
Hail JavaScript !2 -
Damn bro Vue 3 sucks actually. It's just a big function now with arguments like "`this` can be sometimes confusing when TypeScript is used." - hell no, my component was a class and this was the fucking class. nothing was confusing about this.
It's all a clusterfuck of magic now, I don't see why writing `ref(5)` or `return { all of your shit }` after `setup() { complete business logic inclusive functions here }` is better.
I was so looking forward to all the improvments, but why do we need these 3 apis with actually no difference, tried to be explained by the same image of colorful blocks in every single fucking article?
what happened to methods? am i seriously supposed to return them from a function? that just feels wrong.17 -
As a Software Design junky, I just enjoy using TypeScript for more conventional C-style programming structures in JavaScript !2

Its sad to see the original creator of Node.js killing it for good.
Ryan Dahl had the guts to agree what he did wrong while building Node.js and some of the decisions which stays even today as irreversible. Hats off for him for bring everything to light and working again towards a solution using deno!
Which uses typescript and with a lot more optimized features, still in development tho.
Alot of people still loves node, including me, but do you guys really think it will last longer?
Ryan Dahl's talk at JSConf EU 2018.

I'll preface this by saying that TypeScript is a beautiful language.
But also UTTERLY INCOMPLETE.
Here's what I'm trying to do: give the compiler well-defined contextual type information for a decorator's argument (a lambda signature) and for the decorated class method, so the user would not have to toil and type every single argument.
But does that happen? No.
I'm honestly disappointed.

Setting up ts linting is a pain in the ass..
Until you realize you could try to reload the window. So your settings actually pick up you know.. -
Why are there so many testing framworks for JavaScript? Jasmine, mocha, buster ... and for spies, stubs and mocks, there is sinon and for assertions, there is chai. And oh you can record entire external api calls with nock and whatever else I forgot. I am a bit overwhelmed by this overambundancy of libraries. Writing tests is supposed to be easy.2

It's been awhile, for the heads up I'm that good dude applied a job as MIS few months ago, knows a little bit python and the manager finds out, he told me I gotta make a Warehouse Management Software for the company in C# PLUS MIS regular work(server management, user trouble-shooting and stuff).
after I finish my Warehouse Management Software about a week ago, my manager told me which I quote:
"wpf is not enough! we gonna bring it to multi platform like a web interface can be use on employee's phone as barcode reader and do things can be done as wpf can.
aaaaand we need RFID integration for the whole system working with Identity Server on Azure.
AAAAAAND we need it online before Feb 2020."
I guess after C#,
I'm learning typescript and angular now.
oh by the way my position is MIS with MIS salary.
Does this means after all these shits. I can apply as RD my next job right?2 -
MFW I worked longer than 8 hours because of a weird bug that turned out to be caused by lack of typing in a third-party library. Was supposed to be a number but I was giving it a string 🤦♀️Need more sleep.
The funniest part is the library was written in Typescript. HmmMMMMmm...
Throw a `parseInt` or warning for wrong type in there for me, fellow devs! Save consumers of your library a headache!! -
Anyone know how to go about unit testing an application that is made up of:
- Electron
- Node
- React
- Typescript
(React using Typescript of course).
Electron has its own framework (Spectron), people seem to use Mocha with Node, React has its own tools like React testing library (and testing UI components will probably end me) and Typescript seems to play best with Jest - but a special Typescript flavour of Jest called ts-jest is preferable because the only other option is having Babel and its Typescript support that doesn't type check.
I want to beg for the sweet release of death.4 -

I've heard "someone" saying, that typescript and c# are somewhat similar. Now I've never worked with c#, but I still doubt it. What do you, human of devRant, think?9
-
What's the point of using TypeScript if you type all of your code with `any` or worst part is you don't provide any types!?
P.S
If you're anti-typescript or any static linting tool, I know this will not prevent any runtime errors, but this is part of the testing/code quality. My teammates do not care for quality, and I'm tired of it.2 -

Am i the only one who thinks TypeScript is not necessary, more some kind of overhead creation?
Whats your opinion about TS? Do you use it or just "good" old plain JavaScript?5 -
TypeScript types are fun. Problem is: the check is compile-time only.
I just wasted an hour not understanding that an integer passed from command line was actually getting transmitted as a string. The library, where that value landed as parameter, happily ignored the non-matching type and worked as if the value has not been set at all!
Dear library maintainer, please enforce your parameter types! Throw an error right into my face saying I shall not pass anything but an integer! Don't just continue to work to produce false output correctly. Thank you!
Dear TypeScript, I really want type checks on runtime.
Dear JavaScript: Why did you ever think loose types were a good idea? (And I say that as a PHP developer as well.)2 -
Oi, typescript, why do you take 15 seconds to transpile my project!?
It's a waiting game for the unit test to even start :/4 -
Joined a new company as front end developer after working for a legal tech for 3 years. The codebase is shit here. There is this ReactJS developer who has done everything except for following standard code practices. No modularity, no reusable components. Some files go beyond 2000 lines of codes. It is a literal nightmare.
The worst part is, he does not understand that he has written the worst code. I dunno how to handle this now.8 -
TypeScript! Why you default compiler option "pretty" to false!? Why would anyone want this as false? This is such an amazing feature disabled out of the box! GNARF!
I USED TO GREP FOR ERROR TO GET ERROR HIGHLIGHTING!

For fuck's sake Microsoft, why on Earth do you announce a half-done feature? Was this an idea from marketing? Upper management? I am fairly certain that nobody who actually writes code for a living would have ever approved releasing a rushed feature to a TYPE SYSTEM.

Enough with this “I’m a full stack web developer but I find JavaScript to hard and demanding to keep up with”. Unless your using typescript which is still remarkably close, half or more of your job will be JavaScript. And sorry but it’s only growing and latching on to everything. It’s a bad time for you refuse to learn it.1

You know the feeling when your mom come to visit and then start reorganize your stuff and complains about the way you choose to live ?
That how I feel when TypeScript come into my code and start reorganize my functions into Classes and bug me, all the time, about the types I must use to active there function
( thanks to Angular )1 -
So just started to get stuck into my new book on TypeScript. My immediate feeling is TypeScript is amazing and makes JavaScript a zillion times better. What's others opinions?4

when some lib using Typescript they think that they can show in the top of the page function with the full fucking complex signature and that explain everything you need to know about what the function do and how to use it !
what about some simple basic signature, table of attribute name and meaning. and some good examples
like we have then on the old day ?? -
Productivity Hack: I'm a java developer who decided to write a productivity app that integrates to-do, pomodoro and eisenhower matrix altogether with reports generation. this will also help me logging at work. I'm also using electron + angular2 + typescript, just because, well, I'm trying to learn new stuff.
Long story short, many many many many days later, i'm still waiting for that productivity boost. What is dis webpack? Wat u mean loaders? Wat promises? electron-prebuilt is now electron? Wat u mean npm and node should be updated? .....
Please send help1 -
Sigh :/ The npm default to print its own logging messages is so annoying I now do this:

Am really confused between app development and web development. Where should I proceed guys?
Am CS student right now. Mostly learn C# (WPF, xamarin) in mean time.
But recently am getting love on Angular 4. For that I learn typescript (I know HTML and CSS basics btw) and willing to start learning it in upcoming vacations.
But thoughts coming in my mind is am doing good to get into web development? If yes what should I do with the knowledge of C# then? 😣😣. Or should I stick with app development and get dipper knowledge in it?
Really confusing stuff man. Am really need some good assistance on this topic!1 -
So maybe stack overflow is better for this...but it's kind of ranty too so here goes.
Any react + typescript devs here? Cause I did something dumb. I ejected the project because I needed to build a custom express implementation...long story short, I can't run a webpack react dev server or use hot reload. Which is a PAIN! If I wanted to wait for a full TS and react static recompile after changing a css prop....I wouldn't be in the web game!!
Has anyone else had this and fixed it??1 -
The adventurous world of javascript and typescript never ceases to amaze me.
I'm investigating some paths to take for migrating this legacy project which has incurred some technical debt. Because of... reasons... even the frontend Vue project needs to be built on a Windows system. No, you can take your hands down, even wsl or docker aren't alternatives here. It's a long story and ties in with said debt.
I'm keen on rebooting the entire frontend using a newer Vue cli and scaffold up all the essentials like eslint and typescript which is currently not used. This is gonna be sweet.
Except, typescript (BY Microsoft) doesn't play well on a Windows (BY Microsoft) filesystem because of a recent change to support - get this - wsl. I can't decide if it's hilariously ironic or genius.
This response about sums up my current mood. https://github.com/Microsoft/...
Of course, further digging in other repos like node only turns up issues closed due to it being on Windows' end.
So now my readme has a troubleshooting section describing how to make changes to your filesystem if you run into issues in Windows and I want to go home.6 -

I dont know if i should learn typescript, i really like how it shows any error if you have done some mistake in the code in realtime.

I work on react and javascript on daily basis.11

I'm using typescript and run mocha acceptance tests. I was confused as to why my tests were failing on the Jenkins albeit they passed locally just fine.
I couldn't find the error. Just after making a pause, implementing something else, I realized what the problem was:
As I renamed a folder from `fixtures` to `tapes` my test run on the Jenkins suddenly claimed to not find the files in `fixtures`. Yet in my code base there was no occurrence of the string `fixtures` anymore and then it hit me like a brick wall:
I have old transpiled files in my outDir, the `dist` folder on the jenkins! Locally, I make sure to run `git clean -fd` once in a while, so I never was hit by it it locally. Yet my jenkins had really old files in the `dist` folder. And just running `rm dist/* && tsc` fixed the entire ordeal.
Well, JavaScript is so 2012 and typescript is the new shit, yet transpiling the code can leave to some quite strong headaches.2 -
Maintained some old Dockerfile. Confused how `npm install` could possibly work as the working dir of that command was a *subfolder* with *no* `package.json`. Yet it verifyably installed into the correct package on build to the parent folder with the `package.json`. I assumed a grunt or npm script taking care of it, yet found nothing. Digging deeper, I realized: [this is by design](https://github.com/npm/npm/...).

When elements of an union are distinguished by a boolean, VSCode's Typescript plugin can only do type elimination if I branch by "== true" and not if I just branch by the boolean.
This is because Typescript treats booleans as an union of the constants "true" and "false", and compile-time elimination can only be done if I use syntax that makes sense with unions. Logical evaluation, for some reason, doesn't.
The fact that this issue can even appear is deeply concerning.1 -

I just wasted a few hours by not realizing that array.prototype.concat does not act upon the array calling it but rather that it returns a new concatenated one :/

Why TypeScript and Angular2 encourages you to link scripts directly from node_modules folder? What happens when you move the project to server(you know...the place that doesn't know about that folder). And how's the bundling gonna work?

Today I escape from the clutches of the legacy iOS project ive been stuck in for about a year and a half.
Starting on a new team, totally different stack (TypeScript/Angular).
Its bad that what makes me happiest is that we have unit tests, something thats been missing from my life for so long now. I might actually get to do TDD now.
Life is good. -

Today I had a dream, not sure if I can call it a nightmare:
I was doing ReactJS + TypeScript. but no matter how much I try, I can't seem to match the type of the variable/object. The IDE ( WebStorm ) kept showing RED marks under the variables & I kept trying, but no solution!
& Finally I woke up at 3 am :|1 -
The final hour of mental torture among many of finding a complex solution to an otherwise simple problem in a React/Typescript project:

when using typescript, how often do you use 'any' versus the actual type? and for objects, do you use models or do you use 'any' and parse the objects?11

Scala is a better TypeScript. Feels so easy and natural to switch. Too bad it mainly targets Java devs. Scala.js is not nearly as popular as it should be.3

I love Typescript's challenges. Today I had to make a generic interface that replaces every property in its parameter with either itself, a promise of itself or a different property keyed `obtain${key}` which is a function returning either the value or a promise of it. Not a very difficult challenge, but it was very satisfying to solve.
If anyone has the patience to attempt it I'm very curious what more experienced type theorists than myself come up with.1 -
About to write (and publish) my first npm package with TypeScript. It's basically just for json stream writing because the existing packages suck and/or don't do what I need
Guess my actual project I need this for will have to take a bit longer now -

So I finally gave up trying to get TypeScript ES6 modules to work. Back to CommonJS it is, because fuck me I guess. I mean it *did* work... Until I also had to use a commonjs module at which point tsc basically tells you to fuck off with that2

Sometimes I think that TypeScript is like a poor developer's Haskell. I thought "Isn't this supposed to support functional programming?" and searched for a way to do currying or partial application, and only found hackish solutions :/ Then again, maybe I don't know Haskell well enough to make a proper judgment.1

Guys can you help me with sentry integration in angular 7 app ?
It capture errors but need to know the line number in the typescript source file not in the minified js file. Any hint ?3 -
I like typescript so dont get me wrong, but its pre-compiler is rediculous sometimes! It makes assumptions on similar named primitives that I can quite it just by naming the variable differently, even if the same naming is used in entirely different scope.2

Since I can't get my user stories today, I started on trying getting my angular frontend to communicate with my symfony backend. I now feel like I need a lot of climbing gear, because I get the feeling I went too deep into the rabbit hole.

tldr: Fuck webpack with a big rusty pipe.
I have a class and in the construct a method is called with an imported value as the argument. This imported value is declared like this:
export const EXT = 'whatthef';
Seems like webpack moves things around in such a way that this constant isn't aceasable in all contexts.
Spent a good 4 hours figuring that out 🙃2 -
I was playing with NativeScript, it looks cool as fuck, writing typescript and angular + native ui elements that you can style with css. This is underrated.

Is programming a website/basic backend program in TypeScript with NodeJS actually a good idea? Or should you be programming it in C#, Rust, (not PHP), Golang, etc?
I personally feel like NodeJS has pretty amazing performance considering how much less code you would write compared to the other options. Although I feel something like Rust (haven't used it yet) would be more robust but more work.
Note: I only currently know JS, TS, C#, Go and obviously HTML, CSS10 -

You cannot upgrade npm via `npm update npm -g` inside a docker container. Yet one can download a npm install skript that performs the installation of the latest npm update ...

Which syntax is "correct" TypeScript syntax ?. I prefer the first one. But what's about guidelines ?
Note for UpperCase variables: yes I know. We use that syntax to differentiate public and private variables. (Yes I know that doesn’t exist in JavaScript)

I need help structuring a new TypeScript project built on a MERN stack. I used CRA for the client, so I opted to have separate tsconfig files -- one for client (auto-generated by CRA) and one for server (extends node12 tsconfig). However, I'm trying to setup eslint and prettier globally so that the lint/style rules are uniform across the codebase. CRA adds an eslint config that extends react-app, which is fine, but I'd like to still have my global rules. I have written my eslintrc.json file and am happy with it, so I placed it in the project root directory. I figured I would install eslint, prettier, etc. in the project root, then when I run eslint globally, it would lint the server code with the global rules and the client code with the global rules and the react-scripts rules.
However, react-scripts complains that I've installed a newer version of eslint in a parent directory. I can either ignore that rule or use the same version as react-scripts, but it seems like react-scripts is going to run eslint on its own when I run npm start, regardless of if I have a global config. What should I do? Is there a better way to structure the app?1 -
Article helps to understand the core concepts and the best patterns around Redux

What do you guys recommend to read when starting Electron project with React and Typescript. I'm kinda stuck. :/
I've already make a simple Electron app with Js, but few people recommended me to try React, Redux and Typescript. But idk where to start.
P.S: Tried the boilerplate, reading docs.. I need something that explains what does what and how.4 -
Being lazy sometimes and writing type definitions after I’m done developing something rather than before (hence wasting time as doing that work is meant to help with the development process in the first place...)

This is a TypeScript question, but that shouldn't matter.
Would you use dependency injection to get access to your controllers inside your router files, or would you just import them?2 -
Excuse my question I might be the one to blame, but on Typescript 3.7 JSON.stringify parses numbers as strings, while on 3.4 it was working without issues.
I'm no pro in web dev but I did use JSON.stringify lots of times and that's something strange here, not sure what the cause is, but when I parse number props again using parseInt(value.toString()) it works .-.2 -
I really want to divide this frontend into two parts, one that faces the users and other for administrators so I can release changes on both without works on one part blocking the other, but, I have many question, like, how do I manage authentication in two different React projects from one login page?
Maybe there are more problems than benefits, what do you think?3 -
Loopback 4 really is pulling me out of the expressjs shithole... It really feels like I'm avoiding a lot of tedious work.
"B-b-bbut you have to use typescript and its a slower"
I've preferred typescript ever since angular 2 came out, and the 'slower' comment is invalidated by the fact that, when working on projects that are distributed between multiple devs, are marked by silent errors and serialization issues, and can change datasource types between customers, then the benefits of typescript and loopback's CLI far outweigh any potential slowdowns that may be caused. If you can find me an alternative that does this better, please let me know.1 -
Well, the time has finally come to tackle Typescript! So far it's not too rough-so I think I might put some effort into levelling up my redux skills too so I can put them together...maybe!1
