New to full time front end development from designing. Can you give any tips that would save my time and make life easier

Web front-end? In that case:

1: disable cache in the browser you use for testing (F12 somewhere)

2: use query parameters on your css/js files so they look new to the users browsers after you've deployed an updated version. Look f.ex. how devrant.com puts "?v=<number>" in their link rels and script srcs.

3: automate #2

As @Buggz said,

- keep cache disabled,

- use versioning on cacheable assets,

- find a good automation tester (selenium for example) this will save you a lot of time in the long wrong

- don’t stress over something not being pixel perfect, it’s the web!

- throw some of that design creativity into your dev work!

- if you need to work with APis (some front end devs do) look at insomnia.rest or postman

And most of all, welcome to devRant

Learn webpack now. The sooner the better.

It will look like gibberish mixed with Egyptian in the beginning but when mastered is a powerful beast.

Also, enforce good practices with a good eslint file.

Learn git and how to do branch and commit properly.
