Building a Simple API

Topic Outline (30-min)

1. Introduction to REST APIs and Their Structure:

   • REST (Representational State Transfer) is an architectural style for building APIs.

   • CRUD operations:

     • GET: Retrieve data.

     • POST: Create new data.

     • PUT: Update existing data.

     • DELETE: Remove data.

   • Example of a REST API endpoint:

     bash코드 복사GET /tasks - Retrieve a list of tasks

2. Setting Up Routes and Handling HTTP Requests:

   • Use the http module or a framework like Express to handle API routes.

   • Example route setup:

     javascript코드 복사app.get('/tasks', (req, res) => {
       res.send(tasks);
     });

3. Integrating with JSON Data:

   • Data is stored and managed in JSON format:

     javascript코드 복사const tasks = [
       { id: 1, title: 'Task 1', completed: false },
       { id: 2, title: 'Task 2', completed: true }
     ];

4. Using Tools Like Postman for Testing APIs:

   • Postman is a popular tool for testing API endpoints.

   • You can make GET, POST, PUT, and DELETE requests to verify the API responses.
