Level 7: Set Up Postman for Testing

Download and install Postman (the desktop application, not the website) so you can test your localhost server. Postman allows you to send HTTP requests to http://localhost:3000 and inspect responses.

Option 1: Postman Desktop App (Recommended)

• Download from postman.com/downloads
• Install the desktop application (not the web version)
• The desktop app can access localhost URLs

Option 2: Postman Extension

• Install the Postman extension for VS Code or your preferred browser
• Ensure it supports localhost connections

Once installed, you’ll use Postman to test your API endpoints throughout this project. Make sure you can access http://localhost:3000 before moving to the next level.
