Make a GET request to JSON API in Node.js?

Question

Wondering how I can make a GET request to a JSON API using Node.js. I preferably want to use Express however it is not necessary, and for the output to be on a Jade page. I'm still completely new to Node.js and backend languages as a whole.

Answer 1

var request = require('request');
request('<API Call>', function (error, response, body) {
    if (!error && response.statusCode == 200) {
      var info = JSON.parse(body)
    }
})

This will make an HTTP request to the API and upon success parse the response into JSON.

As far as getting the response onto a Jade page do you wish to do an API call (to your own server) and then use AngularJS/ jQuery/ another framework to fill in the information?

If you wish to add this to your own route consider embedding it like such:

var express = require('express');
var cors = require('cors');
var request = require('request');
var app = express();
app.use(express.bodyParser());
app.use(cors());
app.get('<Your Route>', function(req, res){
  request('<API Call>', function (error, response, body) {
    if (!error && response.statusCode == 200) {
      var info = JSON.parse(body)
      // do more stuff
      res.send(info);
    }
  })
});
app.listen(3000);
console.log("The server is now running on port 3000.");
