Reading a user profile

The read method will use fetch to make a GET call to retrieve a specific user by ID. Since this is a protected route, besides passing the user ID as a parameter, the requesting component must also provide valid credentials, which in this case will be a valid JWT received after successful sign-in.

mern-skeleton/client/user/api-user.js:

const read = (params, credentials) => {
  return fetch('/api/users/' + params.userId, {
    method: 'GET',
    headers: {
      'Accept': 'application/json',
      'Content-Type': 'application/json',
      'Authorization': 'Bearer ' + credentials.t
    }
  }).then((response) => {
    return response.json()
  }).catch((err) => console.log(err))
}

The JWT is attached to the GET fetch call in the Authorization header using the Bearer scheme, and then the response from the server is returned to the component in a promise.
