How can I use dynamic URLs in my web application?

Dynamic URLs allow you to create flexible and user-friendly links that can change based on user input or data. You can implement them using frameworks like Express.js for Node.js or Django for Python.

Can you give me an example of how to implement it in Express.js?

Sure! In Express.js, you can define a route with parameters like this: app.get('/user/:id', (req, res) => { const userId = req.params.id; // Fetch user data using userId }); This way, the URL can change based on the user ID.

What about handling query parameters?

For query parameters, you can access them using req.query. For example, app.get('/search', (req, res) => { const searchTerm = req.query.q; // Use searchTerm to filter results });.

Are there any SEO considerations I should keep in mind?

Yes, ensure your dynamic URLs are descriptive and include relevant keywords. Also, use canonical tags to avoid duplicate content issues.
