[@key_michael]

In continuity to this tutorial I would suggest that a set of videos showing how to deal with persistent data would be ideal. Most people can learn how to create the API URIs, but the real deal is when it is for a developer to manage to records to a Database. That's MySQL for example and not Firebase which happens to be more simplified. Also, an example from various programming languages should help a ton of people to move things forward.

I have a suggestion... recently I was in a big project and I was confused as hell. We had many arguments and fights about what folder structure to use for our API: - Where to put validation? - Use validation in express.js way (in the routes like a middleware) or separately? - Where to put routes? - break routes into different files or one single file? If so, break based on what? There are just countless questions to be answered in this regard. The problem also is that nobody makes videos about folder structure for enterprise level applications. It would be great if you could make it a thing.

[@iarde3422]

for some reason stupid youtube was deleting my comment over and over, until I split it this way.

[@iarde3422]

For many years, i tried to figure out, what it is, reading lengthy articles, downloading 200-300 page books, that I never wanted to read for more, then the 1st chapter, watching videos about it, asking about it on forums. Up to this point, the understanding of what this technology is was very vague, although, I have many years of experience in programming software and web apps (frontend and backend).

[@iarde3422]

I just couldn't grasp the concept of what this weird technology is about and what it is for. I thrived for this short, complete, simple and sane explanation from the beginning. I couldn't get some programming jobs only, because they were asking about this weird RESTFull creature thing and I didn't know what it was.

[@iarde3422]

Basically, everything, that I've already been doing on web development is already RESTFull, I just didn't know, that it was called that, especially, that most of the similar techniques, I came up myself, just refining my development techniques over time.

[@iarde3422]

THAAAAAAAAAAAANX!!! Finally, I know, what it is! And I can throw away those lengthy no good books about RESTFull API, because, all they had to do was just make the same explanation, that you did! Why, oh, why I couldn't find anything as simple and explanatory, as your video, years ago! I dropped a big boulder of my shoulder!
