Unexpected End of JSON Input when pulling JSON from Reddit

Question

I am trying to pull some reddit posts from their json feed, as it is done in this example:

var http = require('http');


function getRedditPosts() {
  var url = "http://www.reddit.com/r/jokes/new/.json?limit=1";

  var request = http.get(url, function(response) {
    var json = '';
    response.on('data', function(chunk) {
      json += chunk;
    });

    response.on('end', function() {
      var redditResponse = JSON.parse(json);
      redditResponse.data.children.forEach(function(child) {
    if(child.data.domain !== 'self.node') {
      console.log('-------------------------------');
      console.log('Author : ' + child.data.author);
      console.log('Domain : ' + child.data.domain);
      console.log('Title : ' + child.data.title);
      console.log('URL : ' + child.data.url);
    }
      });
    })
  });
  request.on('error', function(err) {
    console.log(err);
  });
}

getRedditPosts();

The problem is that I am getting a unexpected end of JSON input. Why is that?

undefined:1

There is a typo in your url `reddit.com/r/jokes/new.json?limit=1`` — Francois
@FrançoisP. Thanks, weird. Postman accepted this just fine. — ffritz

So, there is a typo in your url reddit.com/r/jokes/new.json?limit=1.

And you should use https instead of http package because reddit is https. Corrected code :

var http = require('https');


function getRedditPosts() {
  var url = "https://www.reddit.com/r/jokes/new.json?limit=1";

  var request = http.get(url, function(response) {
    var json = '';
    response.on('data', function(chunk) {
      json += chunk;
    });

    response.on('end', function() {
      var redditResponse = JSON.parse(json);
      redditResponse.data.children.forEach(function(child) {
    if(child.data.domain !== 'self.node') {
      console.log('-------------------------------');
      console.log('Author : ' + child.data.author);
      console.log('Domain : ' + child.data.domain);
      console.log('Title : ' + child.data.title);
      console.log('URL : ' + child.data.url);
    }
      });
    })
  });
  request.on('error', function(err) {
    console.log(err);
  });
}

getRedditPosts();
