In this tutorial, we will learn how to quickly integrate HttpClient service in Angular 8 application to consume RESTful API JSON data from the server.
HttpClient enables the communication between client and server through many available methods like get(), post(), put(), delete() etc. We will also add Error handling techniques using RxJS operators at one place in our service.
For demonstrating real-world scenarios, here we will create a Student management application with the following operations:
- Create a new Student record using the post() method.
- List/Get Students data to show in a table using get() method.
- Update any Student data by clicking on Edit put() method.
- Delete any Student by clicking Delete on table row using delete() method.
