lb remote-method

This function is used to extend functionality of models by defining new methods.

If we add a buy method on product:

A new endpoint /Products/{id}/buy is automatically created on the API
We have to declare and implement the buy method on the prototype of the Product model

During the remote method creation, the generator asks for:

Create user by posting on "/Users":

{
  "email": "<email>",
  "password": "<password>"
}

Get an authentication token by posting on "/Users/login":

{
  "email": "<email>",
  "password": "<password>"
}
