The client must send this token in the Authorization header when making requests to protected resource.

  Describe express middleware

  Middleware is software containing functions that execute during the request-response cycle and have access to both the request object (req) and the response object (res). Middleware is executed during the window between when a server receives a request and when it sends a response.
