Project organization
Next.js provides several features to help you organize your project while following routing conventions.
File colocation
Each folder in Next.js represents a route segment, but a route is only publicly accessible when a page.js
or page.tsx file is added to the respective segment.
For example, accessing localhost:3000/users with the following folder structure /app/users/line-chart.js
will
result in a 404 error until a page.js file is defined. Only the content returned by page.js is sent to the client.
Files colocated inside route segments within the app directory won't accidentally become routable.
Route groups
Route groups allow logical grouping of routes and files without affecting the URL structure. They can be created by
wrapping a folder in parentheses: (folderName)
For example, (auth)/register , (auth)/login and (auth)/forgot-password can be accessed at /register, /login, and
/forgot-password. The auth route group helps organize routes more efficiently.
