  1. The App Router (_app.js) is used to configure app-wide settings and components, such as headers and footers. The Pages Router (files in the pages directory) is used to define routes and handle individual page rendering, including dynamic routes. You generally need to learn both to complete a full application.

  2. In Next.js, there are two types of routers: the App router and the Page router. Let’s discuss the differences between them point by point:

    Purpose:

    1. App Router: The App router handles the overall routing and navigation for your entire application. It is responsible for rendering the correct pages based on the URL and managing the transitions between pages.
    2. Page Router: The Page router handles the routing within individual pages of your application. It allows you to define dynamic routes and access the route parameters for rendering specific content on a page.

    Location:

    1. App Router: The App router is typically implemented in the _app.js or _app.tsx file. It wraps your entire application and controls the routing and layout for all pages.
    2. Page Router: The Page router is implemented in each individual page component. It defines the routing logic and determines the content to be rendered based on the current route.

      In short, the App router is responsible for the overall routing and navigation of your application, while the Page router focuses on routing within individual pages. The App router is configured in the _app.js or _app.tsx file and provides global routing functionality, whereas the Page router is implemented within each page component and handles routing specific to that page.
