Introducing REST APIs Chapter 4Also, in controllers/users.js, we have the following:
module.exports.controller = (app) => {
// get homepage
app.get('/users', (req, res) => {
res.render('index', { title: 'Users' });
})
}Adding a GET endpoint in the users controller
Let's add a route to our controllers/users.js that will fetch all the user's records from
the database.
Currently, with the code we have in our users controller, when we
visit http://localhost:3000/users, it only returns a title, Users. Let's modify this
code to incorporate a GET request to fetch all user requests.
Fetching all users
First, start the server with $ nodemon app.js. Now, in controllers/users.js:
var User = require("../models/User");module.exports.controller = (app) => {
// get all users
app.get('/users', (req, res) => {
User.find({}, 'name email', function (error, users) {
if (error) { console.log(error); }
res.send(users);
})
})
}Now that we have our code in place, let's test this endpoint using the Postman app. In the
Postman app, add the necessary details in the URL. When we hit the Send button, we
should see the response as follows:
