Sadly there doesn't seem to be a way to do this. The ideal way would be to create two separate Routes for your purpose.

<Route exact path="/tasks/:id" component={...} />
<Route exact path="/tasks/:id/notification/:notificationId" component={...} />

If you really must only declare one Route, you could use a custom regex rule (the part that is wrapped in parentheses after the parameter name declaration):

<Route exact path="/tasks/:id/:notificationId(notification/\d+)?" component={...} />

However!! - note that the notificationId parameter will include the substring "notification". For example, if you have:


You will have a taskId of "123" and notificationId of "notification/456" (the whole string)!

That said, the route above will match the following paths:

  • tasks/123
  • tasks/123/notification/456

but not:

  • tasks/123/notification
  • tasks/123/notification/abc
  • tasks/123/456


TL;DR - You probably want to use two individual routes as shown in the first example above.


It looks like there isn't any support for this in React Router [1]. Maybe you could just use a query parameter instead? /tasks/:id?notification=notificationID.
