Search - "mongo"
Hired a new backend Dev. He writes a script and sends it for testing...
Tester: "It's not working..."
Backend Dev: Goes to Mongo and deletes the tester's whole profile...
I cant control my laughter every time I remember this incident...He claimed it was a mistake, I don't think that it was a mistake...the tester had it coming...
"It's not working" that's all he says every time...I mean at least give me something to start with...!5
Senior frontend Dev at my company: "microservices best thing ever"
Also him: "Relational databases gonna die"
Also him (talking to the DB team): "You're gonna dissapear, Mongo is the future"
Me: "Eh... Dude, Mongo is still a database.."
Always tell junior devs the same.
You'r not going to become the senior dev or architect you have in your grand vision by sitting around this company fulfilling mundane tickets.
Start thinking through new ideas, possibilities, software that you think could really help a specific niche Or pick a model that already exists. The ideas prior existence doesn't matter but having a new idea that has potential has always inspired me to keep pursuing it.
Break out lucid charts, learn how to map out your domain objects and their relationships. Build out a service map of how you want things to work together. You dont have to know how context boundaries or demilitarized zones work or any that technical jargon. At the end of the day those concepts <should> develop organically and then the jargon will come to you like "oh thats the term for this". Some people learn better from knowing and then implementing. I usually come to it organically then learn about it later. Thats the point of this though. Read up on it, understand enough to map it out and then start building them out.
Use a language you want to be proficient in but are not. Use a framework you want to understand but do not. If theres an auth protocol in high demand that meets your needs but you do not understand, run with it. You'r proficient with mysql; mongo would also be a good fit for the business needs but you've never used it. Perfect, use mongo then.
Find avenues of improvement down the line. Maybe the simple records resource server would be a good candidate for GraphQL. Pull in a pub/sub to increase service communication/aggregation, learn websockets to maintain a vital client interface. If you dont know what the fuck im talking about, perfect! Jump in there. Start small, build up, tinker.
You'll meet soul sucking blockers all along the way and thats the biggest thing that separates seniors from juniors is having worked through these issues before, time and time again. Embrace failure, embrace change, maintain initiative because you can be another miserable dev that keeps the cogs turning making a decent 50k salary or you can be a positive catalysis.16
Cool. 300$ in Google Cloud credits. Maybe I can get to one of those cool projects I’ve been wanting to get to.
spins up server
installs material design components
makes title bar and navigation
*okay, good enough for now, i’ll come back later*
*never gets around to it, and 300$ in free credits get exhausted by server running 24/7*12
I think I will ship a free open-source messenger with end-to-end encryption soon.
With zero maintenance cost, it’ll be awesome to watch it grow and become popular or remain unknown and become an everlasting portfolio project.
So I created Heroku account with free NodeJS dyno ($0/mo), set up UptimeRobot for it to not fall asleep ($0/mo), plugged in MongoDB (around 700mb for free) and Redis for api rate limiting (30 mb of ram for free, enough if I’m going to purge the whole database each three seconds, and there’ll be only api hit counters), set up GitHub auto deployment.
So, backend will be in nodejs, cryptico will manage private/public keys stuff, express will be responsible for api, I also decided to plug in Helmet and Sqreen, just to be sure.
Actual data will be stored in mongo, rate limit counters – in redis.
Frontend will probably be implemented in React, hosted for free at GitHub pages. I also can attach a custom domain there, let’s see if I can attach it to Freenom garbage.
So, here we go, starting up modern nosql-nodejs-react application completely for free.
If it blasts off, I’m moving to Clojure + Cassandra for backend.
And the last thing. It’ll be end-to-end encrypted. That means if it blasts off, it will probably attract evil russian government. They’ll want me to give him keys. It’ll be impossible, you know. But they doesn’t accept that answer. So if I accidentally stop posting there, please tell my girl that I love her and I’m probably dead or captured28
Him: Relation databases are stupid; SQL injections, complex relationships, redundant syntax and so much more!
Me: so what should we use instead? Mongo, redis, some other fancy new db?
Him: no, I have this class in Java, it loads all the data into memory and handles transfers with http.
Me: ...... Bye!5
99% of our server-side code is Python and PHP (legacy applications).
Asked a junior dev to make a small update to a PHP site so we could have it run some cleanup server side. Plenty of existing PHP code to look at and piece something together. Should be 50 lines max.
Did he use the existing PHP code to do this task? Nope. Did he at least use Python? Nope.
"I couldn't figure it out and Node.js seemed to have good support for mongo so I used that instead."
Much would of rather he put in twice as much time to learn the tools of our stack.8
On the presentation for my database project my team and I showed a NodeJS + Mongo + VueJS project with cloud storage capability, nothing fancy but did everything from scratch (from token auth and system encryption to the frontend CSS and the database) the teacher made some questions and meh'd at it.
Behold team two's project, WordPress with a standard template and phpMyAdmin, teacher loves it because "it's so beautiful"
Guess who just failed that class?
God I love college, it's the best time investment I've ever done and it'll surely pay out.11
Wrote angular service, named it "MongoService", handles calls/requests to mongodb. Spent an hour wondering why it wasn't running one of my functions from controller. Just realized I am calling MangoService instead of Mongo. Lord help me.2
Learning Node.js, Express, React.js, ES6, and Mongo all at once. Haven't been this excited about programming since college. This stuff is incredible!10
Database tip of the day:
Spent hours on Amazon's DynamoDB and ultimately found it couldn't do what I wanted, not without a complicated workaround.
Switched to Mongo and had it working in literally under 5 minutes.
Hooray for Mongo 😀4

My company now of three months has proven to be the most perfect environment for me to pursue what I would call a long road to senior level expertise in software development. They say you can only grow as large as the room your in will allow. Everyone around me has 30+ years of experience and is ridiculously intelligent. Theres not one feature that does not correctly use sufficient design patterns,. Code is actively refactored to the point that it reads like a book. New technologies are pursued, btw dont tell me mongo cant be proficient in a large environment, these guys have proven differently (it just takes the right abstractions to keep it safe). I encourage every dev to find that team that pushes you to be more.5
Fun day, lots of relief and catharsis!
Client I was wanting to fire has apparently decided that the long term support contract I knew was bullshit from go will instead be handled by IBM India and it's my job to train them in the "application." Having worked with this team (the majority of whom have been out of university for less than a year), I can say categorically that the best of them can barely manage to copy and paste jQuery examples from SO, so best of fucking luck.
I said, "great!," since I'd been planning on quitting anyways. I even handed them an SOW stating I would train them for 2 days on the application's design and structure, and included a rider they dutifully signed that stated, "design and structure will cover what is needed to maintain the application long term in terms of its basic routing, layout and any 'pages' that we have written for this application. The client acknowledges that 3rd party (non-[us]) documentation is available for the technologies used, but not written by [us], effective support of those platforms will devolve to their respective vendors on expiry of the current support contract."
Contract in hand, and client being too dumb to realize that their severing of the maintenance agreement voids their support contract, I can safely share what's not contractually covered:
- Stream based programming
- Angular 9
- Any of the APIs
- Dotnet core
- pretty much anything not in a commit
I'm a little giddy just thinking about the massive world of hurt they've created for themselves. Couldn't have happened to nicer assholes.6
So last semester, my college made a class compulsory to attend.
We were taught, "How to install MongoDB on Windows"...
With screenshots, not even live installation.
I wanted to die.. So much.. 😖5
Usually I develop in python, mongo, cordova and node. Few days back I installed Windows on my laptop cause I needed to use the Visual Studio for a specific task. Then I thought that if I can setup the python, mongo, cordova and node stack on Windows then I don't need to switch between Linux and Windows frequently. And that was a horrible decision.
It took almost 8-10 hours to setup that shit, and still I couldn't make it work. There are so much complexities and those do not make any fucking sense! I mean why the hell I need to add the python path to the environment variables, and then again add the pip path separately. Then mongodb can not autostart. And finally I needed to make and build a package, and that waa the moment when I just scrapped it.
It takes me 2-3 hours to setup a fresh Linux box (which supports apt) including the OS installation. Same for the osX. I still wonder that why Microsoft does this! If Windows is for non-dev and non-tech people then why don't they release a Windows developer edition? Developing anything except ASP.NET and Java in Windows is a fucking nightmare for me!11
Had an idea for an app. I started writing the prototype in Node since I just had a simple API in mind. Wanted to have some very basoc crud functionality going and then hook up a nice interface to it. It has to do with logistics and analytics so I just wanted to start sketching something small, and being that i have been successful in doing an API like this in the pass with node and mongo for a local company I said why not.
I have finished a good chunk of it. Gotta love that js productivity. But what tripped me out about it was:
Check how big the folder size is: 387mb
I tripped, there was no way in hell this shit was that heavy. I am basically using Koi(to give it a whirl instead of express, gotta start testing koi sometimes right?) And some joi with morgan and winston. That is it. I am using mongo since legit its the only one i know, even with that there really can't be that much right?
Check node_modules size.....10mb....wtf? What
Sure as shit....forgot that i was storing the mongo data folder inside the app's root folder.
This would have been nothing if it would have taken me 30 seconds to figure it out.
I was losing my mind for 30 mins before i decided to properly verify
I need some sleep6
Set up a server, code for hours using node and Mongo trying to realize your dream. FINALLY complete it after a lOOOng time of blood and sweat..
Then find out that a Noob who didn't know the first letter of web programming used FireBase and did what you did in a fraction of the time
I think I've reached the point where I can question what I've done, my purpose in life and.. As for my confidence I think it successfully descended during my last visit to the bathroom3
You used Node and Mongo to handle highly concurrent financial transactions. What where you thinking.10
I wrote a node + vue web app that consumes bing api and lets you block specific hosts with a click, and I have some thoughts I need to post somewhere.
My main motivation for this it is that the search results I've been getting with the big search engines are lacking a lot of quality. The SEO situation right now is very complex but the bottom line is that there is a lot of white hat SEO abuse.
Commercial companies are fucking up the internet very hard. Search results have become way too profit oriented thus unneutral. Personal blogs are becoming very rare. Information is losing quality and sites are losing identity. The internet is consollidating.
So, I decided to write something to help me give this situation the middle finger.
I wrote this because I consider the ability to block specific sites a basic universal right. If you were ripped off by a website or you just don't like it, then you should be able to block said site from your search results. It's not rocket science.
Google used to have this feature integrated but they removed it in 2013. They also had an extension that did this client side, but they removed it in 2018 too. We're years past the time where Google forgot their "Don't be evil" motto.
AFAIK, the only search engine on earth that lets you block sites is millionshort.com, but if you block too many sites, the performance degrades. And the company that runs it is a for profit too.
There is a third party extension that blocks sites called uBlacklist. The problem is that it only works on google. I wrote my app so as to escape google's tracking clutches, ads and their annoying products showing up in between my results.
But aside uBlacklist does the same thing as my app, including the limitation that this isn't an actual search engine, it's just filtering search results after they are generated.
This is far from ideal because filter results before the results are generated would be much more preferred.
But developing a search engine is prohibitively expensive to both index and rank pages for a single person. Which is sad, but can't do much about it.
I'm also thinking of implementing the ability promote certain sites, the opposite to blocking, so these promoted sites would get more priority within the results.
I guess I would have to move the promoted sites between all pages I fetched to the first page/s, but client side.
But this is suboptimal compared to having actual access to the rank algorithm, where you could promote sites in a smarter way, but again, I can't build a search engine by myself.
I'm using mongo to cache the results, so with a click of a button I can retrieve the results of a previous query without hitting bing. So far a couple of queries don't seem to bring much performance or space issues.
On using bing: bing is basically the only realiable API option I could find that was hobby cost worthy. Most microsoft products are usually my last choice.
Bing is giving me a 7 day free trial of their search API until I register a CC. They offer a free tier, but I'm not sure if that's only for these 7 days. Otherwise, I'm gonna need to pay like 5$.
Paying or not, having to use a CC to use this software I wrote sucks balls.
So far the usage of this app has resulted in me becoming more critical of sites and finding sites of better quality. I think overall it helps me to become a better programmer, all the while having better protection of my privacy.
One not upside is that I'm the only one curating myself, whereas I could benefit from other people that I trust own block/promote lists.
I will git push it somewhere at some point, but it does require some more work:
I would want to add a docker-compose script to make it easy to start, and I didn't write any tests unfortunately (I did use eslint for both apps, though).
The performance is not excellent (the app has not experienced blocks so far, but it does make the coolers spin after a bit) because the algorithms I wrote were very POC.
But it took me some time to write it, and I need to catch some breath.
There are other more open efforts that seem to be more ethical, but they are usually hard to use or just incomplete.
commoncrawl.org is a free index of the web. one problem I found is that it doesn't seem to index everything (for example, it doesn't seem to index the blog of a friend I know that has been writing for years and is indexed by google).
it also requires knowledge on reading warc files, which will surely require some time investment to learn.
it also seems kinda slow for responses,
it is also generated only once a month, and I would still have little idea on how to implement a pagerank algorithm, let alone code it.4
mongo in slang means idiot, which comes from the term mongol or mongoloid, which is a deprecated word that used to be used for sufferers of down syndrome. So MongoDB means "Down Syndrom Data Base"
Also mongo means huge, so it may have been named after that.12
Tldr; its a long introduction
I've been on this app for quite a while now. As a shy cat watching from a distance and reading all kinds of rants. Anywho I feel comfortable enough to crawl out of my shell and introduce myself. Since I feel you guys together made such a pleasant and safe community, I'm really happy to be a part of it!
Anyway I'm Sam, 24 year old, from the Netherlands. My favorite color is green. Mostly the green you can find in nature. The one that calms you down:). I'm a very introverted person but always very curious and eager to learn new things.
I started to program when I was 12. I did assembly and C++. Because I liked making cheats for online games. Later I learned about C#, Java and Python. Mostly used it for web stuff, scraping, services etc. But also chatbots (for Skype for example).
Currently I'm 2 years in as a data scientist, mostly working in Python.
But on the side as a hobby and with an ambition I have a basic understanding of full stack development.
Mostly Nodejs, express, mongo, and frontend, no frameworks.
(I will later ask you guys some more questions about that! I could really use some advice!)
Anyway enough about me! Tell a bit about yourselves! Happy to get to know you all a little better!12
A few months passed. Still jobless. I am a php dev btw. In stead of giving up. I made a simple app allows people vote up and down restaurants I Melbourne Australia. https://melres.shopshop.space. I learn a lot about nodejs, react, redux, express, mongo, nginx, Ubuntu. I apply for nodejs job, IT support, DevOps, API job, backend job. All got rejected. Due to experience and competiton. I even ask I can work for DevOps for free. Still no reply. In stead of giving up, I keep learning, doing the thing I love. Focus on learn how to learn. Day in and day out. Hopefully it gets better.5
Best: a school project with tons of cool stuff: NodeJS, Express, jwt, Jest (unittests), VueJS, pwa, Mongo, Python, OpenCV and tesseract
Worst: the teacher complaining all the time on the background colour of the website6
Don't get me wrong, I am a huge fan of disparate microservices when building applications. I started 4 years ago building monolithic applications on symfony, laravel and .net.
SPAs have not only made my applications more flexible but have allowed me to build more flexible front ends. But I almost ALWAYS have this dirty, unorganized feeling when working in this microserviced approach.
My data always feels scattered. Because my backend doesn't have as tight of a grip on what view is being rendered and what data it gets, I am always left with a sense of disorganization and lack of security. I have more anxiety that my application will unravel at any given moment then I've ever had and that keeps me up at night.
Does anyone else feel this way when working with disparate systems?
And dont even get me started on mongo. Again, I love it, but the feeling of disorganization is intense when using it.4
So... About a month ago 2 interns started a project from scratch at my company. My boss gave them a project to follow as an example (more for the api and database side).
Wednesday they ended the internship and I've began to help fix the rest of the kinks that were left to be fixed. Friday we were finishing up the app and api to send to the client for tests. The database was created with 4 tables that were equal in structure... Imagine that you need a table for orders and they have status like pending, cancelled, finished and accepted. What they've done was they created 4 tables, one for each status....
Why the hell would you do this???5
Thing that just occurred to me.
Write backend of website in Node with Mongo.
Write front end of website by using PHP to echo data from mongo and inline styles. PHP will also echo any inline JS that needs to make AJAX calls back to handle responsiveness.
Write a website with JS as its backend and PHP as its front end because the world has gone absolutely mad and you dgaf anymore.2
I always feel odd when I hear about MongoDB. Cuz mongo is a German curse word for someone with down syndrom...7
Thinking about transferring the majority project from mongo to MySQL. It makes sense rationally but - feels like there is a creeping darkness is looming over me.7
Neat: MongoDB. Fairly easy to use, intuitive-ish JSON API. Thinking about using it on a project. Excitement.
Neater: Data validation. You can have it drop writes that don't match a schema. Excitement intensifies.
Braindead: It absolutely will not tell you exactly *why* the write doesn't meet the schema, leaving you to figure that out on your own, smart guy. Mongo smugly crosses its arms and tells you to go back and do it right without actually telling you what the problem is.
Fucking braindead: This has been an open feature request since year of our lord two-thousand-and-fucking-fifteen. https://jira.mongodb.org/browse/...7
Sometimes I don't know if my co-worker is that stupid or...
Well, he came to me with an strange problem with mongoose.
I looked at the error message. And guess what the database was not reachable. Asked him, did you check the mongo db service. No. Of course the service was not running. Told him to restart it. Then he restarted robo t not the service itself. Major face palm. He then asked me if I knew why his service was not running. Do I look like some kind of wizard? Told him to check the logs. Long story short, his drive ran out of space....2
So here's is the thing.
For some weird reason I decided to work at a VC funded startup. For 15k year,(I live in a really poor country).
So, let me describe the hell I'm in now, and if for some good grace you happen to be hiring, please consider saving me from the horror that's ahead.
Company got funded 5 months ago, main owners are, an economist and a civil engineer with no programming habilities whatsoever.
They took 1 month to assemble "a killer team", with no hiring expertise they handpicked a CTO that came in 1 month later and took a month of vacation in his first month of work.
He didn't do any specification of the system that needs to be built.
The 2 naive owners hired the rest of this "killer team".
The team is good, but have no appreciation of planning.
They've built and rebuilt the backend system twice, once in graphql and the second with plain http (is not real rest, just a http api), in front of, guess what a mongo database.
This mongo DB is not only one, but 7, because we have 7 microservices, and each has its own database.
After some time, they decided to fire their CTO, and hire one more programmer(that's me), because the CTO wasn't doing anything.
The app has 3 parts, the app per se, a business version, and a help desk, guess what the helpdesk just appeared last week on the radar.
Long story short, we have one month to deliver what couldn't be built in 5.
When I decided to work for these people, I did not imagine the kind of clusterfuck that I was getting into.
It took me 1 month to realize the whole situation, now, I really would like to see some help from the deities of any religion, not for the project, that project is doomed.
It's how I'll pay the bills after that clusterfuck collapses that worries me.
Now in the startup no one is talking about how stupid the whole situation is. Or how far back we are. And at this point there's very little that could be done about it, I have a feeling that it could still be accomplished, but it's fading day after day.
I will do my best to live the best of this experience, and do as the musicians in the Titanic and keep playing the music even after knowing the Titanic is sinking.5
I'm still unable to find a single advantage of using the Firebase Database over MongoDB, yet people keep suggesting me to do so.
WHY? I can host Mongo for free on my own server and won't have to worry about *READING* costing money!7
The application that was working fine on local host failed to do one task which is to read users data from excel and save it on mongo db, in some collection document's embedded document. My last night and today morning was tensed due to this. So I decided to re deploy the same application on another instance that I have. Worked completely fine
I am php laravel developer with little knowledge about nodejs.
I got selected by one startup as nodejs developer.
frankly I am not better nodejs developer than my competition who were rejected.
I completed oral interview with my nodejs theory knowledge at a time of technical round , they gave us task to create crud with fantastic front end and nodejs mongo as a back end.
I developed front end in bootstrap but at a time of backend, I just copy paste code from github.
and changed everything variable and other proof to hide reality. in mean time other candidates were actually coding everything then I took time to understand this code and I submitted after few candidates.
in last round they ask me to explain code which I explained properly and I get salary 40k/month INR.
I know it is cheating but I wanted this job badly.6
Product Owner: Hey, can you guys own this incredibly fragile legacy app built with Grails, Angular and Mongo?
PO: Go on. You can rebuild it!
Me: Sigh.. ok
- 6 months later -
Me: When can we rebuild this bloody app??
PO: lol sry no budget lmao!
My boi states that node's biggest issue has always been npm and the quality of packages. I always contradict those statements by saying that if one uses community standards and the best packages then one does not need to worry about the quality(i.e mongoose over some unmaintained mongo wrapper etc)
I sometimes catch myself finding that my way of thinking adapts better to JS than it even does Python (which is his preference for deep learning) and whilst there are some beastly packages for python in terms of quality and usefulness such as matplotlib etc that one can do great things with the equivalent JS.
I mean, tensorflow.js came from the same wizards that did tensorflow (obviously) and i find the functional approach of JS to be more on par with how we develop solutions.
I am no deep learning expert, and sadly I have no professional experience with machine learning. But I venture to say that we should not cast aside the great strides that the JS community has done to the language in terms of evolution and tooling. Today's Js is not your grandaddy's Js and thinking that the language is crippled because of early iterations of the language would be severely biased.
What do you guys(maybe someone with professional experience) think of Js as a language for machine learning?
Do you think the language poses something worth considering in terms of tooling and power for ml?3
In a time where a web dev is expected to know, well.. everything... Backend -JAVA, python, nodejs and C++ would be great.
Front- angular, react, other 10 libs
DBs -sql, mongo, redis, elastic, kafka, rebbitmq
Also be devops on the side with AWS and docker kubernetis and more stuff
How the f is that possible?
In my real job for the last couple of years and different companies, I usually use 1 language/framework & 1 main DB.. and although it's possible in some companies, but in mine, ppl dont get access to AWS etc..
So let's say there's me.. a server side dev for years.
So I decide to be better and learn Golang.. cool lang, never needed in my job, after few days of not using it I forgot all I learned and that was it.
Then I realized I gotta know some frontend cause everyone want a fullstack ninja nowadays.. so I tried Vuejs.. it was amazing .. never got to use it at work, cause i was a backend, and we didnt use frameworks on our products back then..
Then I decided to learned nodejs, because this is the coolest thing ever.. hated it, but whatever... Never got to use it at work, cause everything was written in other lang which the whole team knew... Forgot the little i knew.
Then I decided, its time to see what Angular is, cause everyone started using it... similar idea to vuejs which i barely remembered, but wow it's a lot of code to remember, or I'll have to google everything.. so I went over it, but can't say i even learned it.
Now Im trying to move on to python, which, I really am learning in depth.. however, since I dont have real experience with it, no one gives me a shot at being a python dev, so again i feel like I'm trying to memorize syntax and wasting my time..
Tired of seeing React in all job ads, i decided to have a look what's that all about.. and whadoyaknow... It's fucking the same idea as vue/angular with again different syntax..
THIS IS CRAZY!
in how many syntaxes do i need to know how to make a fucking crud api, and a page with same fucking post form, TO BE A GOOD PROGRAMMER?!?6
Boooooy symfony has changed a lot since laaaaaaaaast time I used it a long time ago.
Some days ago I finished a little project I built using express and mongo. I want to port it into symfony to see how the newest version (which is 4) fares and I must say. I am really impressed and happy with what I am seeing :D
This sucks because I am going to be dying to use this at work and I know that I am not going to be able to use it unless i act all sneaky and shit4
Boss: Write a program to generate a report using some data from an existing one.
Me: OK, I will look into doing a POC
Boss: Also it would be stored in Mongo so all the data is queryable
Me: OK I will generate the file first
Boss: But it needs to be in DB, couldn't you just upload it when done?
This discussion goes on for 30 mins+ preventing me from finishing release related work...
IF THE FCKING POC/REPORT ITSELF IS WRONG OR IS MISSING INFORMATION/CAN'T BE GENERATED WHY THE FUCK DOES WHERE IT'S STORED MATTER?!!!!!!!!!!! WHY ARE TOY EATING TIME ON THESE TINY DETAILS THAT DON'T MATTER AT THE MOMENT.
FUCKING GET YOUR PRIORITIES STRAIGHT. YES EVERYTHING IS DOABLE... JUST NOT NOW.....5
There's very little good use cases for mongo, change my mind.
Prototyping maybe? Rails can prototype, create/update/destroy db schemas really quickly anyways.
If you're doing a web app, there's tons of libs that let you have a store in your app, even a fake mongo on the browser.
Are the reads fast? When I need that, use with redis.
Can it be an actual replacement for an app's db? No. Safety mechanisms that relational dbs have are pretty much must haves for a production level app.
Data type checks, null checks, foreign key checks, query checks.
All this robustness, this safety is something critical to maintain the data of an app sane.
Screw ups in the app layer affecting the data are a lot less visible and don't get noticed immediately (things like this can happen with relational dbs but are a lot less likely)
Let's not even get into mutating structures. Once you pick a structure with mongo, you're pretty much set.
Redoing a structure is manual, and you better have checks afterwards.
But at the same time, this is kind of a pro for mongo, since if there's variable data, as in some fields that are not always present, you don't need to create column for them, they just go into the data.
But you can have json columns in postgres too!
Is it easier to migrate than relational dbs? yes, but docker makes everything easy also.12
Today a co-worker (I am going to call him 'boss') ask to another co-worker (I am goin to call it 'useless piece of shit' or 'ups') to explain to me a new task, becaus boss was to bussy with a new release for a client.
Idk how but ups managed to explain all wrong, like terribly wrong.
Ups: "Dev, all you have to do is fix some queries from local files"
Dev: "Ok, seems legit"
Try the local files, nothing happend
Dev: "weird... ups why this is happening?"
Ups: "I know the same as you, ask boss."
Dev: "boss this."
Boss: "what the actual what? ... this is all wrong. The config file is in mongo, in this IP, we don't use local files anymore. I tell ups to explain this to you so I can atay focused on this other task, but now I lost the double amount of time"
Dev: "oh... sorry, I will fix the remote queries"
I hate ups, every fucking time soneone need something from him this happend or worst...1
There is a parody of "Cheap Thrill's" by Mongo DB.
Yes Mongo DB ,it was for thier product promotion(Mongo DB Atlas)!
BTW it's one of the best DB I have ever used, it binds well with NodeJs
Here is it:
I know its way old ,but just want to share
If I learn React, Redux, Mongo, Express and Node, will I be able to build a full web application?22
Has anyone here used MongoDB for relational databases? I am trying to use MySQL with Node but I feel like the whole thing is a mess. There are some ORMs like Knex or Sequelize for MySQL but they are pretty crap. I am thinking if I should just move onto MongoDB instead of MySQL, at the same time I feel a little dirty to store relational data in a document store :(18
This rant must be because of my oldness. I was never into Pokemon, but my oldest kid was.
So the hashtag for Pokemon Go makes little sense to me. It could just as easy be an insulting Poke Mongo (ie harazzing a Down's Syndrome person) as Pokemon Go.
There. Out of my system. Please carry on.4
So far I've created two pods, mongo & Go
Exposed those pods using services
Their IP is 10.x.x.x and accessible from my machine only (virtual lan I'm guessing only known to host), but my machine's network ip is 192.x.x.x therefore, not accessible from outside world and to do so I need to put nginx in front to receive requests and route them internally.
Is there a way in kubernetes to make it work like nginx in terms of:
Kubernetes listen to port 80 (for example) route based on received url. As you know in enginx we define a server block with server domain_name.tld
Anything similar in kubernetes? I've cheked ingress-nginx controller, and also saw LoadBalancer but that requires a cloud provider.
If anyone can also give an example it would be great, so far examples I checked ended up screwing my setup and had to reset kubectl to get things back working18
Some facepalm things I've discovered recently:
- Node's require("http") doesn't work for https - you have to require("https") specifically.
- Mongofiles (command line utility for Mongo, imports files as GridFS) cannot input more than one file at a time. Regex doesn't work. [Ended up making a puny Powershell script to do it].
- Airtable doesn't let you download your attachments, even if you export a csv - it's just a url to the image on their cloud.
It's been an exhausting day.1
SO , i just ran into this database called ArangoDB and it claims to single handedly beat Mongo,Neo4j,Postgres and claims to be capable of handling any use case you can throw at it.
If anyone could verify this claim , such an ideal database just makes me question it's existence.5
Hey there people, I have a few questions regarding neo4j. Your experience could also be very useful to me here @dfox.
1. Is neo4j good for storing user data, like password hashes, etc.. In addition to the regular relationships with other components of the ecosystem
2. Is neo4j good enough to accommodate a really large number of users..
3. Does DevRant use a dual database, like user info in Mongo and relationships like comments and ++ on neo4j or is it like everything on neo4j
For q.3, if you're not @dfox then just provide an idea of how you would handle the situation.7
Start mongo, start my node server, start the app, quick "5mins" look on dev rant started 30mins ago!1
1. Learn Vue.js
2. Learn some backend framework or language like Express.js or ROR
3.Learn Mongo DB
4. Make a progressive web app
Bored and want something to do? Learn MongoDB. There’s SO many great resources out there! I have legit enjoyed these first three courses in Mongo University (+1 on Udemy).6
Shifted to new office few days back.
Just had to put up with the shitty intermittent internet connection.
SSH failing and coming out for every 50 secs.
Trying to take Mongo Dump and restore for the past 2 hours. Finally! ufff.
When the network is disconnected SSH gets disconnected. Fine. Acceptable. Again, when the network gets connected, it should start from the same place right ? Dumb Enough. But i wanted that today.2
I'm a rather young developer, self-learned everything and started when I was 13 (now 20) but I still feel like I'm a total beginner since I have not yet mastered the things I am OK at.
Php (laravel, since it makes things much easier), js (jquery, bad at vanilla, have used angular and ember but not mastered), node, linux, html, css, photoshop, illustrator, sql, mongo and windows servers
I know little about many things, can create things that are asked of me but the methods I use are rather bad imo.. ex: I finish coding a section of a site, but when I need to add a new feature I find myself rewriting most of the stuff to add the new feature and in the end still feeling like the code could be optimized further, even though I have no idea how.
TL;DR I write bad code, but things work as long as I am monitoring them. I know little about alot of stuff but mastered none of them.
What should I do? Go to school for programming?8
A simple app, just proceed with the coding. it doesn't matter whether it's mysql or mongo. Get the shit done guys!3
Regretting I ever put Mongo on this app's stack... It's been great to learn in the process, but man it can be a bitch to setup sometimes...
So I have a friend. One of few who I can freely speak with using my natural language (so that means, narrow down topics to IT, mix some of my native language, mix in lot of english and mixture of our favourite languages terms (don't ask me how it works, but it works brilantly and its actually easier to communicate)). And its true friend, seriously.
But when we meet, 80% of time we spent together, every, single, fucking time we argue (in cultural maner, its more of discussion) about what enviroment and what languages have advantages against others. And it pisses the fucking hell out of me, when he takes his enviroment, takes his problems with exac his enviroment, and applies his favourite solutions to it, and goes on how they are fucking awesome and brilliant, and than I reply, sure in my enviroment if I ever had XYZ problem, I wouldn't say use mongo DB becouse I can do it my way, and it would work well too, but it's not really the way I really should solve XYZ problem, becouse in my enviroment you dont have it in the first place. And he will fucking go on, but at least he understands my solutions and finds various details where HIS solution works better. His solution to his problem vs my solution to non-existant problem.
But that's actually an example of much grander thing that I want to rant about. You see, that's not all that bad, we keep it civil and we somewhat enjoy these discussions even if often times, they are pointless. It's like playing games and shit like that, so it's not the point, I just used the example to make it clear what I mean later down the line.
So, to the actual point. What the living fucking fuck is wrong with people, for living fucks sake they cannot physically, mentaly, virtually or otherwise change mindset and point of view if they are telling YOU what to fucking do, what's better to do, etc.
What the fuck! You have around 0.1% of context that is in my head, and my solution works with most of it and your bearly manages to deal with your given 0.1%, so kindly please for living hell, fuck off telling me what to do, what is better in my fucking situation etc. You don't know most of shit I know about my own situation (dosent apply to people with coma and heavy mental issues, sorry its not 100% universal) that I know, yet you have something in your brain that fucking allows you (dosent tell you "its no-go lol") to try push thru your shit to me like it was your fucking life. It's not.
And to be clear, before someone gets sad becouse I was to broad and generic. If you giving advice you can do it properly. And there are people who legit have mindset "well, if I was you and known what you told me, I would do XYZ", but for what the living fuck reason most of people I know have more mindset of "Do XYZ coz fuck you if you dont, coz dat is my opinion and shit and I dont give a living fuck if it does what you want"2

What cheap/good quality node.js hosting provider for nodejs/react/mongodb app do you suggest? (including sale, black friday etc.)9
What's with all the hate towards mongo as of late? Just a few years ago it was all the rage.
I haven't yet used it myself, I just find it to be a sudden stark contrast in opinion2
So what is the best free Mongo DB client for Mac? What are you using aside from the command line?
I prefer good ui and features. Thanks! 👍5
Just got off a call with Mongo expert... Seems it's not good for large systems that need to be fast and scale...5
Hopefully at work we have successfully migrated from a combination of MySQL and Mongo to only Postgres. Also we finally split up our monolith into medium sized services, so we can actually do something interesting and update our dependencies.
And port one of the services from Java Struts to Django..
..but that is only if developers were to set the plan...if sales/management: new feature here! new feature there! sell sell sell! No time for maintenance!
After a year of using mongo in prod and personal projects I have realised some things. Its really nice early on the project, especially when there are changing requirements and for small projects or proof of concepts.
But when you make commercial software things tend to get more complex and relational. Stakeholders want reporting and even a report building which a document store isn't the best at.
With most projects projects when they get big things get relational and this becomes more and more expensive to handle in terms of compute power and developer time.
I don't doubt mongo has its place, maybe as an secondary specialised data store or if the project is inherently document oriented.
I just spent 2 hours tearing apart an express app to figure out what was wrong... turned out I hadn't started the mongo server. Doh!3
So I accidentally used an email as a username to create an account through Jira for mongodb to report a bug.. That apparently breaks the entire Jira login system. I cant recover my account, and I can't create another account because my email is already in use.. Thanks Jira for deciding I'm going to bar before I go home today...9
My one of my favorite open source project was Re-think DB!
It was highly light weight real-time DB.
One fine day, I read a blog by the CEO / founder, telling we are under loss since there is no financial support! and we are closing it, by just keeping the website and docs of prev version alive!
I was heartbroken , for days!
This takes the top place for favourite oss project
It has high no. of stars in github than Mongo db, reddis, etc..2
Everybody is bussy!
So let's going to give this mess to the one who never worked with mongo, does not know the objects in the DDBB, add to it some weird way to build queries in java to it and hope for everithing end well!
End well = need to be done today.
Guess what? Not for today! I have no clue of how to clean this shit.1
IDK about every other mongo consumer but for me, working with mongo/mongoose feels like I constantly have no real structure to my data.
Like im able to implement whatever i want anytime without any consequences or faults and yet that wide range of freedom has seemed to leave my structure in a confusing place.
I can explain a mysql driven domain pretty accurately because its defined rather accurately. It really takes some work to have a real understandable model with mongo.2
am i the only one who likes quoting Blazing Saddles in git commits?
most recent being adding mongo to a project.
A question for Web developers:
I'm planing to start working on a web part of my project. Important part is that it's supposed to be working with MongoDB. The idea is to build a small digital library, so the main functionalities should be user registering, his login, querying database for books, showing list of results and viewing pdf files up to 200MB size.
Please note that this is a school project on which I'm working after my job, and not something to be deployed to customers.
I went ahead and tested t2.micro and lambda+dynamo(free tier)
You definitely get better performance and load handing with lambda+dynamo (5rcu+5wcu)
Tested the two with wrk and a simple GET which reads an item from a database of 90k items.
I could share more details with you if youre interested, but with 2000 requests, 100 connections and 4 threads. I got about 26requests/s on ec2 and about 260r/s on lambda.
Latency for ec2 was about 28s.
Latency for lambda was about 22s.
ONE WEEK i've been working on this migration from Mongo to Kafka for a service that will probably handle 5 requests A MONTH for this thing that launch an entire JVM and take 10 seconds just to create a so-called topic
New startup - our backend stack is php, js, mysql, mongo & redis
Can you guys recommend nice-to-have internal tools that could make out lifes easier? We’ve been using confluence so far and thinking on grabbing a jira license.
Any advice is helpful 🤪11
Guessing my rant free streak is over. Trying to connect to a mongo atlas cluster. Just migrated from mlab as mongo Inc is discontinuing the heroku add on.
Migration went well. I can connect to atlas cluster via mongo shell.
Reactive mongo claims it supports dns seed list. I add mongodb+srv connection string. Doesn't work.
I go back to atlas and allow all ips access (migrating staging dB first to make sure all is well so I can whitelist all ips) - > send a request-> mongo error. No primary node is available.
Disconnect from my network, connect to another network, same thing. I push the connection string to my server, test using an ssl connection to make a request, still no primary node available. I am about to lose my mind.
I'm taking a look at neo4j after working a lot of mongo. Takes some getting used to but I think I could use it well for my next project.4
Just wanted to share this because i've made the hardest step - actually started working on it.
Kinda feeling proud of myself.
Kinda feeling weird of being proud of such a thing.
Don't wish me luck, wish me the will to keep not giving up when it's the hardest
I've just read the article about CloudPet, and honestly I am disgusted.
I don't even know what to say beyond that. I call out my team on basic stuff like forgetting to escape, but this?2
We recently encountered a strange Mongo DB behaviour or rather strange Mongo Shell behaviour.
Read how it made us scratch our heads.
Check out: https://prakhar.xyz/how-mongo-gave-...4
Any recommendation for managed mongodb service provider and server provider?
I am usually a fan of Digital Ocean but DO doesn't seem like a good option for mongodb (especially for mongo-noobs)5
hate to create huge one timers. got to build huge migrate tool (luckily there its not thousand of users) to migrate from mysl to mongo, then to upload assets properly at place. Its also got to be a new api test. Which also i wrote.(the api). Eveything is fine except the time. They wanted me to finish two days ago and i almost got it. But my head is about to explode and code is messy...
Need some help from anyone experience with MEAN.
Do you have a separate cache for data or is Mongo the cache as well?
Basically we have 500GB+ DB of data, how would you architect a MEAN system around it so that it's fast and stable1
At what point should I feel my skills are strong enough to apply for a junior front end position? I'm going to be getting my bachelor's in May for CS and currently I am pretty familiar with HTML/CSS/JS, understand jQuery and bootstrap, know some basic node/express/Mongo (I know, I'm learning postgres, calm down), and now I'm kind of deep diving into angular.3
Made a node js app that dynamically let users stir up websockets on their port choice for HL7 (healthcare messaging) message transmission as translation later before outgoing to a receiver they specify. Learned meteor, react, express, and mongo on this project. Lotsa lotsa new tools. And yes I know learning meteor was pointless F off3
Spent the whole day trying to get php driver for mongoDB to work.. made a php script that connects to remote db, the connection kept returning null/false no matter what i did.. in the end i uncommented a code below that fetches data with the "null" connection and suddenly I see data printed out 😐 well f you too very much 😡
Tomorrow I'll finally play with mongo 😊 i hope it won't be too much of a pain with php2
I need to work on a mysql project for university but i know nothing about it,
Can you tell where is it deployed for production purpose, like mongo DB stuff can be deployed on heroku11
just 'Hello world' me trying to make a restful api.
*Got Ktor, loved the koltin, hated the deploy, quit.
*Got Django, loved the python, hated the sql migration, quit.
*Got Node, loved everything, hated mongo, can't quit now...
*Got Firebase DB now, I feel the hate monster...ghostly voices, saying, Work my slave, build it... dont stop, 'cause we're right behind you...
....and we're waiting for you5
Me: Assigned to do some NoSQL injections test cases in December on Jira by product owner.
After asking him about it, he said it can be vague and it’s only for developers to get an idea. I also have this restriction where I can’t really keep actually data or databases in our test sample application, so I could only mock mongodb. Product owner says just mongo is fine.
I do it. Now it’s January, product owner away for a month we so director is managing it. She then schedules me to talk to database team. I show them the very simple test cases which essentially just inject payloads I found online into different parameters specified in test case. They say if that’s it. I say yes. They say what’s the point of this. I said that it’s probably to test your database clients and ensure they’re rejecting bad Malicious input? They then keep asking but I’m just the dev and tell them the product owner is away. Then the guy calls my test case essentially useless and the others agree. Then they tell me to do it for other databases which I can’t mock like couchbase even tho my PO said it’s fine for mongo only.
Am I just being silly here? I am pretty new to working in a dev environment so please feel free to be blunt.4
Architecture for Java REST API going to build/port from existing NodeJS one.
So Spring Boot + *
Lots of concurrent requests and large MongoDB calls. Current APIs use like 4GB memory for each instance because they don't use stream/pipe the response. Hold all data in memory and then return it all at once to user.
And well we expect more load in the future, so want to do this the right way.
So my understanding since this morning, is there's the blocking? MongoClient, (find* returns List) and now a Reactive MongoClient which is very async and like JS promises. Based on Pub, Sub model.
But the downside of JS promises was callback hell.
So actually 2 questions.
1. For each request, the db call done using the same MongoClient/db connection such that if there are 2 requests one would block the other?
2. Reactive Mongo would be non-blocking by design so would be better to support streamed responses?8
Sometimes I'm questioning all my skills... I have a maven based project which uses hibernate as OGM to the mongo database. Everything working fine and already in a productive environment.
Now I changed some lines of code at the business logic to adjust for the changed database model. So far so good.
After compiling and running on the test environment: exception! "no persistence provider for Entity Manager named xy" are you fu***** kidding me? I changed nothing at that point!
Mongo client for important analytical data reporting was configured with write concern 0 since 2012.
It's a master replica setup...
Neo4j vs Mongo vs SQL
Which one would you choose for a high density scalable database?
Please comment with your ideas about speed and scalability.15
Just a question about a generic social app. Using mongodb , 3 entities ,like comment and post . how do I display posts in feeds with comment count and like count . since its mongodb I can't do joins . the other way is to maintain a data structure on the server side . or yet another way would be making 2 extra queries to db for retrieving like and comments count . Any other way this is possible or is it possible to form a query in mongo db to retrieve all 3 at the same time???1
Can anyone tell me how I can integrate Mongo DB with golang?
I found go-bongo, but it's not well documented.5
Can anyone Tell me. Is there any way to use node js with MySQL or Mongo Db on TERMUX Android.
If you Help me. I will be very thankful to you.
I want to learn but I don't have computer.10
Where can find an all in one guide to set up/configure a ELK environment manually from the tars (not yum, apt-get, docker image)?
I am following the component docs from Elastic but not sure how each component integrates with each other or how to set the mongo connection (DB is not local)5
Month into a project and I can’t decide between mongo and MySQL. I’m using an ORM so I can still have this debate but deeper in I’m going to need some Manuel queries and I really need whatever reads the fastest. I was told mongos selects are much quicker but an article I read this morning said differ.
I'm banging out a couple "showcase" mobile apps for practice, portfolio, and/or as potential templating tools.
I have no issue writing the code, I just wanted to see if I could get a couple pointers as far as user databases go. I'd like to have some "user profile" features generated from a FB...vlike profile images, name, address, contact, yadda yadda yadda. I usually use Firebase, but I am still having a little trouble with the more advanced stuff when it comes to integrating users profile data. I can get values from Google and whatnot, but I'd like to see what my other options are on the smaller scale.
I am currently writing code in Flutter/Dart, ReactJS( not native!), Vanilla Js, Python, and CPP.
I know there's options for client side storage like Shared Prefs, Sqflite, etc, as well as server/DB side stuff like Firebase, Aws, Mongo, Node, SQL, etc- you get the idea.
I just want something with decent documentation that's reliable, not a massive undertaking (at least not for all this little stuff, anyways) and could potentially be a go-to platform configuration in the future. It'd be cool to wire in my Flutter and js shit of possible, bit honestly I'm cool with having separate setups for the time being. Any extra input regarding the use of python and/or cpp as well (either separately or with mobile) would be rad as fuck!!!
I do realize it's a pretty vast area to cover, but I figured it couldn't hurt to see what everyone likes to use for full-stack setups.
Ok so, i have no idea where i can ask this kinda thing so i'm asking it here (i know i could do like stackexchange or dead aws discord servers, ... nvm you know why i'm not going that route).
I'm looking for a comparison between a mongo+node setup on a basic t1.micro instance and a lambda+dynamodb setup.
Each one has it's perks obviously but i guess i sorta prefer whichever one gives best performance on the free tier.
I do know dynamo has 25 reads and 25 writes a second on the free tier, which might be a little less ? I really have no clue.
But how many writes/reads would a basic mongo setup be able to achieve on the t1.micro instance ? Any idea? Do share your experiences with these architectures as well. I'm sort of a newb with serverless, the downsides aren't worth it for me but I'm learning it nevertheless. It sorta tickles some sort of self-torture curiosity fetish (need more self-research to back that).10
What would you suggest to learn the fullstack js (with mongo,express, vue(example), nodeJs) first instead jumping into the specific framework?and wht are the next step after its been learned?
People love to talk crap about MongoDB but it's not horrible for getting in to NoSql databases. Is it good for extremely important production apps? No, but nobody is saying it is.
Why does my database provider now have a rainbow background for their logo? My DATABASE PROVIDER !? Still better the Microsoft sequel's logo though, theirs has swastikas 😂 😂1
I need to know if I’m just going insane or if this is common in other work environments. I’ve had three feature improvements now that required me to connect to our staging Redis to obtain a hash map example that I would then manually put in my Local redis so that the process I am running can successfully run. That’s just one terrible example, I feel like I am constantly making changes to mongo and redis in order to make my environment act the way it is supposed to just so I can properly test my jobs. I don’t think I’ve ever written an application that has resulted in developers having to have a deep understanding of every database abstraction just so they can claw their way through manual database entries so they can continue doing their job5
Ugh trying to refactor a Node.js MUD codebase to use mongodb. It currently accesses/stores it's data in json files via synchronous FS operations. Callback and/or .then hell, here I come!
Follow up sorta...
So I got pulled into a support issue on a day off. Some system was facing timeouts on our servers so had to investigate.
Over the weekend as part of the release, I released the ELK stack I built and today I used that to help.
Pretty much immediately pinpointed which machine was hanging though still had to investigate and confirm so split between KQL and checking the server logs.
One thing I've always griped about is how no one created schema docs for it mongo collections so can't easily figure out what they do or your to get the document needed.
Well guess it's my turn.... Because only I know the schema :)
When is it a good idea to use linked lists?
In my pet project, I want to have a list of items with an index. The index of an item should be updateable, and the index of the other items should adjust.
A linked list would make it very easy to adjust the order since you just need to update the "next" node of 2 items, but I think this would make getting the index of items more troublesome.
What is the preferred way to do something like this, am I just overthinking it, and would updating all the indices of the items not be such a big job?
The project uses React and mongo (express-mongoose) btw, if that's important.4
I'm looking into an app for work. It needs to connect to both a mongo and Kafka server using SSL or something, but different keys basically.
So need to load a jks file in the main() I think except I have 2 files.
I don't remember exactly how it works but I guess need to combine them into 1?
How do I load each though in app? Need to tell mongo, kafkaClient with one to use?1
