You are creating an application that shows data to the user - doesn't matter if he is searching for some specific thing or he is only listing everything you have. What happens if the server responds with empty array? Or with error? Will your application show only empty space or an error message?
I needed to create a simple server, that would have one “public” route
/login and other routes are available only for users with valid JWT token.
That means, the user is allowed to log into the system and then get any data from it. If he is not logged in and he tries to get some data, he only get an error message and 401 ( Unauthorized ) status code will be returned.
