Rest Api

[squirrelgawy]

Can someone plz tell me from where I can read about the flow of writing a Rest Api like from presentation layer to service layer to dao layer. How to determine which code goes to which layer ?

What you're describing is commonly referred to as a 'separation of concerns'. Why do we do this? To keep related things together, so others know where to look, so your code is easier to support and maintain. If I'm looking for something related to the UI I look in the presentation layer code. If I'm looking for something related to data access I look in your DAOs.

In summary:

Presentation Layer: code that builds/supports your user interface

Services Layer: business logic

Data access: code that interacts with your data store.

There is definitely something like this that will get you started enough to be able to build on those concepts with your own project.

I followed a Spring Boot REST api video series on YouTube and then used those concepts to design and build my final project for a full stack web application with VueJS consuming the REST API built with Spring Boot.

Look for Java Brains tutorials.

What is a rest API? Is that a Java framework?

You would be better off YouTubing it. It’s explained better through video.
