?? Exploring Routing in Next.js: From Basics to Dynamic Paths ??

One of the most powerful features of Next.js is its built-in routing system. Unlike other frameworks, there's no need to install external libraries – routing in Next.js is file-based, simple, and extremely flexible.

Here are a few highlights of what makes Next.js routing so effective:

1?? File-Based Routing – Next.js uses a file-based routing system. This means that every file inside the pages folder automatically maps to a route in the application, with the filename determining the path.

For example:

• pages/index.js becomes /
• pages/about.js becomes /about
• pages/contact.js becomes /contact

To create a new route, simply add a new file to the pages directory – no extra configuration needed!

2?? Dynamic Routes – Building dynamic applications is a breeze with dynamic routing. By wrapping a file name in brackets (e.g., [id].js), you can set up dynamic paths, allowing for routes like /post/1 or /user/42.

3?? Nested Routes – Want to group related routes? Simply organize the files into folders inside the pages directory. For example, adding a file structure like pages/blog/[slug].js results in a clean and organized route: /blog/my-first-post.

4?? API Routes – Yes, Next.js has routing for API endpoints too! Inside the pages/api folder, you can create endpoints with full serverless functionality, such as pages/api/users.js for /api/users.

5?? Link Component – The Link component in Next.js enables seamless client-side navigation between routes. This is essential for building fast and dynamic Single Page Applications (SPAs) without full-page reloads.

To use the Link component, import it from next/link and wrap it around any element, typically <a> tags:

?? Pro Tip: Use Next.js’s catch-all routes for scenarios like nested paths or filtering. Just name your file [...params].js to capture all paths at a certain level!
