💡 Hint

Common Mistakes

Using 'route' instead of 'Router' causes an error because 'route' is not a function.

Using 'app' is incorrect because it refers to the main app, not a router.

The Router() method creates a new router object to handle routes.

💡 Hint

Common Mistakes

Using '/' will not add any prefix.

Using '/home' or '/user' does not match the required prefix.

The app.use('/api', router) prefixes all routes in the router with '/api'.

💡 Hint

Common Mistakes

Using 'write' causes the response to not end properly.

Using 'render' expects a template, which is not used here.

The res.send() method sends a response body as a string.

4fill in blank

hard

Fill both blanks to create a router that handles GET requests at '/users' and responds with JSON.

Express

router.[1]('/users', (req, res) => {
  res.[2]({ message: 'User list' });
});

Drag options to blanks, or click blank then click option'

Bsend

Cjson

Dpost

💡 Hint

Common Mistakes

Using 'post' instead of 'get' changes the route method.

Using 'send' instead of 'json' sends plain text, not JSON.

The get method defines a GET route, and json sends a JSON response.

5fill in blank

hard

Fill all three blanks to prefix routes with '/api', create a POST route at '/login', and send a JSON response.

Express

app.use([1], router);

router.[2]('/login', (req, res) => {
  res.[3]({ success: true });
});

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using '/user' as prefix instead of '/api'.

Using 'get' instead of 'post' for the login route.

Using 'send' instead of 'json' for JSON response.

Prefix routes with '/api', define a POST route, and send JSON response.
