I wrote this article and included some best practices, pitfalls, info, and ' what to look out for' when building an Angular application. A lot of these had been personal experiences and lessons learned the hard way. Also, it was really difficult to create this list, keep it short and simple since I wanted to add stuff for beginners and experts.
Try to follow what Angular recommends: don't do things your way
Since you're using Angular, you should follow what the creator suggests and not do things your way. This goes for most opinionated frameworks, not just Angular.
