Notes

Browser Limitation:

Only GET requests work from the browser. Routes like /add-user (POST) and /update-user (PUT) show "Method Not Allowed" in browser. Always use Postman or any API client for these requests.

Data Storage:

Users are stored in memory (users dictionary). Data will reset when the app restarts.

Postman Tips:

Set Content-Type: application/json for POST/PUT requests Use raw JSON body format

Example Postman Flow

Add a new user → POST /add-user

View all users → GET /view-users

Update a user → PUT /update-user/1

View a single user → GET /view-user/1

Delete a user → DELETE /delete-user/1
