Reddit.js

Reddit.js is a browser based wrapper on most of the read-only Reddit API. It makes CORS requests to the Reddit API. Thus only unauthenicated (logged-out) requests are allowed.

Latest versions of Chrome, Firefox, Internet Explorer and Safari are supported.

Usage

Reddit.js is a lightweight dependency-free library which comes with minified source.

• Install via npm install reddit.js
• Or include a link from the jsdelivr CDN.
• Or download the reddit.min.js file from here.

Include the minfied source via script tag like so

  <script src="https://cdn.jsdelivr.net/npm/[email protected]/reddit.min.js"></script>

The reddit variable is exported which can be used to talk to the Reddit API. The examples directory includes usage with pure DOM API. More sophisticated examples are on the way!

  // Fetch the 5 hottest posts on /r/awww
  reddit.hot('aww').limit(5).fetch(function(res) {
    // res contains JSON parsed response from Reddit
    console.log(res);
  });

  // Errors (if any) will be passed to the 2nd argument of fetch()
  reddit.hot('aww').limit(5).fetch(function(res) {}, function(err) {
    // err contains the error from Reddit
  });

  // All Reddit API filters are supported and chainable
  reddit.hot('aww').limit(1).after("t3_23jf8n").fetch(function(res) {
    // res contains JSON parsed response from Reddit
    console.log(res);
  });

  // Subreddits may be omitted
  // Fetch the hottest posts from Reddit
  reddit.hot().fetch(function(res) {
    console.log(res);
  });
