Lesson 9 - Finishing the Node.js API - The GET and PUT methods
In the previous lesson, API extension in Node.js - Schemas, validation, POST, DELETE, we advanced with our RESTful API in Node.js for a MongoDB movie database. Today we're going to finish the GET and PUT methods, then we'll have a product that can be used by a client application.
Retrieving Data - The GET Method
Now we'll extend our GET method for retrieving data from the database.
Currently we have GET programmed for the URLs /api/movies and
/api/movies/id. But that's not enough, as the client will not
usually need all the movies at once. That's why we'll introduce parameters for
the request with the URL /api/movies. We've already decided what
parameters we're going to use in the last lesson when we were adding validation
functions.
GET /api/movies
By default, this query will return an array of all movies including all the information. However, we'll use query parameters to reduce the result gradually at the database level.
