Discussion on: How do you implement REST in an MVC application?

[José Luis Recio]

Backend:

• Models: It connect with database and we use in controllers. (Intermediary between database and controllers)
• Controllers: It does our logic for each endpoint. (Intermediary between Models and Routes)
• Routes: It has a call route method (example: GET /api/users) and the controller to execute when it is call (Intermediary between controllers and Frontend)

Frontend:

• Simply call to your api endpoint with fetch, axios or your library selected)

Example flow with fetch and express in backend:

//Frontend
const getUsers = async () => {
  const response = await fetch('https://yourapi.com/api/users');
  const data = await response.json();
  return data; //Our users
}

//Backend
  //./routes/
  //If we recieve a call to /api/users we call to usersController
app.get('/api/users', usersController)

  // ./controllers
const usersControllers = () => {
  const users = modelUser.get();//Ey model give me users from database
  //Do logic with our users and return it
}

  // ./models
const modelUser = {
  get: () => databaseCall('SELECT * FROM users'); //Ey database give me users
}

In this way:
Do you change de database? Only modify the model
Do you change your logic? Only modify the controller
Do you change your routing? Only modify the route
