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/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
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.
