Angular 12 + Spring Boot + PostgreSQL example: Build CRUD App

In this tutorial, we will learn how to build a full stack Angular 12 + Spring Boot + PostgreSQL example with a CRUD App. The back-end server uses Spring Boot with Spring Web MVC for REST Controller and Spring Data JPA for interacting with PostgreSQL database. Front-end side is made with Angular 12, HTTPClient, Router and Bootstrap 4.
