this course touches the basic of spring framework, its actually crazy how huge the spring ecosystem is

@drexex0f Місяць тому

yes

@Jake295A 19 днів тому

It's hard to find a spring boot tutorial that goes over the basics and the foundations like this one does. Many tutorials out there jump writing into writing code which is very frustrating when you are new and don't understand what the purpose of everything is.. This is massively helpful! Thanks!

You’re missing out then, Mistakenly, I spent the first couple years of coding focusing on one language. Building literally everything with it! However, it annoyed everyone when they would see my contribution to whatever project we were working on. Perplexed on why I did it only in ArnoldC!

@mysmileisfake Місяць тому

Love the tutorial, thank you! I want to ask, in Module 3: REST API, you mentioned using creating new RunRepository() in constructor could lead to millions of instantiation due to requests, but isn't @RestController a singleton? Won't the same controller always be called for all the requests and the constructor will only instantiated once?

How to handle two differnt versions of backend in spring boot3 ? for example in version 1 , we had a simple data model , but in the version 2 we had a data model with different relations ( one to many ) , we have two versions of backend app in deployment ,where as the frontend we developed with Angular also with two differnt versions , How to Handle this kind of situations where version1 of frontend only will connect to version1 of backend app and v2 will connect only with V2 of backend ?

Although the video is so informative and good, it would be nice if you used a dark theme

@DanVega Місяць тому

I actually prefer dark theme but If I would have used that I would have gotten comments that they wish I used light theme. I prefer dark when coding but I think for presentations light theme works best. Hopefully you can dim the brightness and survive light mode.

I get what you are saying in this video but there needs to be an outline maybe of the process. Then describe why each part is used and how its wired together. Watching this video I can see there is so much "assumed" understanding of what is needed to make the project. Its very hard to follow. Its clear this guy knows what he's talking about, but its very difficult to follow.
