How do you create a RESTful API in CodeIgniter?

Answer: To create a RESTful API in CodeIgniter, you can follow these steps:

  1. Extend the Controller: Start by creating a new controller that extends the base controller class provided by CodeIgniter. This allows you to add your own methods that handle different HTTP requests.
  2. Implement RESTful Methods: In your controller, define methods that correspond to the standard RESTful actions:
    • GET: Retrieve data from the server.
    • POST: Submit new data to the server.
    • PUT: Update existing data on the server.
    • DELETE: Remove data from the server.

    Each method should handle the specific logic related to its action, such as fetching records from the database for GET requests or processing input data for POST requests.

  3. Use Third-Party Libraries: To simplify the process and enhance functionality, you can utilize libraries like codeigniter-restserver. This library provides built-in support for RESTful APIs, including features like response formatting, routing, and authentication. You can install it via Composer or download it directly from its repository.
  4. Set Up Routing: In your routes.php configuration file, define routes that map to your controller methods. This way, when a client makes an HTTP request to a specific URL, it will be directed to the corresponding method in your controller.
  5. Test Your API: Use tools like Postman or cURL to test your API endpoints. Ensure that each method responds correctly to the various HTTP requests and returns the appropriate HTTP status codes.
