How do I use route parameters in REST APIs?

Route parameters are used to capture values in the URL. For example, in a URL like /users/{id}, {id} is a route parameter.

Can you give me an example of how to implement this in a Node.js application?

Sure! In Express.js, you can define a route like this: app.get('/users/:id', (req, res) => { const userId = req.params.id; // fetch user by userId });

What if I want to use multiple route parameters?

You can define multiple parameters in the URL, like /users/:id/posts/:postId. In your handler, you can access them via req.params.id and req.params.postId.

Are there any best practices for using route parameters?

Yes, keep your parameters descriptive, use plural nouns for collections, and avoid using sensitive information in URLs.
