Environment Setup & Tools

To build and test APIs efficiently, you need more than just a code editor. You need tools to simulate client requests and inspect raw network data.

1. API Clients (The Essentials)

2. Testing with cURL

Before using a GUI, it's vital to understand how to make requests from the command line.

# Simple GET Request
      curl http://localhost:3000/api/users

      # POST Request with JSON Data
      curl -X POST http://localhost:3000/api/users \
          -H "Content-Type: application/json" \
          -d '{"name": "Pradeep", "job": "Developer"}'

3. Local Development Proxy (ngrok)

When you need to test webhooks (real-time callbacks from services like Stripe), your local server isn't accessible from the internet. ngrok creates a public URL for your local machine.

4. VS Code Extensions

• REST Client: Send HTTP requests directly from your code editor.
• Thunder Client: A lightweight Postman-like extension inside VS Code.
• Prettier: Essential for keeping your JSON examples clean.
