Implement the Course Service

Implementing the course service

To implement the course service for the REST API, we’ll implement the logic in the frontend of our Angular application by following the steps below:

Step 1: Generating a new service

To implement the REST API in our Angular application, we need to start by creating a services file for the course service. We can do this by running the command below:

ng g s services/course

The above code will generate a boilerplate service for us by default.

Step 2: Course service injection

This step involves injecting the newly created course service and the HttpClientModule into our application’s app.module.ts file.
