Creating dynamic routes in Next.js

Next.js is a popular framework for building React-based web applications. One of its key features is the ability to create dynamic routes. This allows you to create URLs that can change based on user input or other factors. In this tutorial, we will walk you through the process of creating dynamic routes in Next.js.

Step 1: Define your routes

The first step in creating dynamic routes is to define your routes. In Next.js, routes are defined in the “pages” directory. Each file in this directory represents a different route. For example, if you have a file called “pages/about.js”, the route for this page would be “/about”.

Step 2: Create a dynamic route

To create a dynamic route, you need to create a new file in the “pages” directory with a special name. The name of the file should be in the format “[route].js”. For example, if you want to create a dynamic route for a user’s profile, you would create a file called “pages/[username].js”.

Step 3: Retrieve the dynamic parameter

Once you have created your dynamic route, you need to retrieve the dynamic parameter in your component. You can do this by using the “useRouter” hook, which is provided by Next.js. The “useRouter” hook allows you to access the router object, which contains information about the current route, including any dynamic parameters.

Step 4: Use the dynamic parameter

Once you have retrieved the dynamic parameter, you can use it in your component. For example, if you are creating a user profile page, you could use the username parameter to fetch the user’s data from an API or database.

Step 5: Deploy your application

When you’re ready to deploy your application, you can use the following command to build your application and generate a set of static files that you can host on a web server:

npm run build

After the build process is complete, you can find the generated files in the “out” directory. You can now upload these files to your hosting provider and your application will be live.

Conclusion

In this tutorial, you have learned how to create dynamic routes in Next.js. Dynamic routes allow you to create URLs that can change based on user input or other factors. This is a powerful feature that can be used
