  • Brief overview of RESTful APIs.
  • Why Flask is a popular choice for building APIs.

Step 1: Setting Up Flask Project:

  1. Install Flask using pip.
pip install flask
Enter fullscreen mode Exit fullscreen mode
  1. Create a new Flask project directory.

Step 2: Building the API Structure:

  1. Create the main Flask application file (app.py).
  2. Define routes for different API endpoints (GET, POST, PUT, DELETE).

Step 3: Implementing CRUD Operations:

Endpoint 1: Retrieving Data

  1. Create a route to retrieve all data.
  2. Implement a function to handle the GET request.

Endpoint 2: Adding Data

  1. Set up a route to add new data.
  2. Implement a function to handle the POST request.

Endpoint 3: Updating Data

  1. Define a route for updating existing data.
  2. Implement a function to handle the PUT request.

Endpoint 4: Deleting Data

  1. Create a route for deleting data.
  2. Implement a function to handle the DELETE request.

Step 4: Testing the API:

  1. Install Postman for API testing.
  2. Create requests for each CRUD operation.
  3. Test the API locally.

Conclusion:

  1. Recap the key steps.
  2. Emphasize the importance of testing and documentation.
