Route GroupsIn the app directory, nested folders are normally mapped to URL paths. However, you can mark a folder as a Route Group to prevent the folder from being included in the route's URL path.
This allows you to organize your route segments and project files into logical groups without affecting the URL path structure.
Route groups are useful for:
Organizing routes into groups e.g. by site section, intent, or team.
Enabling nested layouts in the same route segment level:
Creating multiple nested layouts in the same segment, including multiple root layouts
Adding a layout to a subset of routes in a common segment
Convention
A route group can be created by wrapping a folder's name in parenthesis: (folderName)
Examples
Organize routes without affecting the URL path
To organize routes without affecting the URL, create a group to keep related routes together. The folders in parenthesis will be omitted from the URL (e.g. (marketing) or (shop)).
