RedditJS uses spa-seo-renderer so search engines can crawl this single page app.

RedditJS is now known as!


The code that powers

I rewrote reddit from the ground up using the javascript framework Backbone and the reddit API. I feel that I've created a better user experience as well as additional features that makes for a more enjoyable experience. Follow updates at /r/redditjs.


  • Data Cache: Only have to load up the subreddit once. Once the subreddit is loaded, it will pull the subreddit/single post from memory. (Benefit for both Reddit's server and you! Only fetch once.)
  • Unique Views: View an entire subreddit in a new way. View thumbnails only, full images, and large grid mode. (more to come)
  • Do everything: you normally can on Reddit(*almost everything). Vote/save/hide posts. Comment, Mail, Search all without having to refresh your browser.
  • Bottom Bar: On single post views, you can see a bottom bar that contains all of the posts from that subreddit. If you don't have that subreddit in memory yet, it caches it for later use too. (Faster browsing back to that subreddit in the future). When the bottom bar is not active, it remains at only 20% visibility so you can hardly tell that it's there. I have found that navigating through reddit this way to be more enjoyable.
  • Custom CSS: Subreddit may have custom CSS and flair that goes with them, redditJS uses them!
  • Comment Links: If you hover over a link to an image or Youtube video, it becomes fullsize inside of the comment box. (Future plans to be able to add MEME text to this image right from the image)
  • Permalink Comments: If you visit a link to a permalink of a comment in Reddit it only shows that comment, I've always found this annoying. RedditJS will show that linked comment first and all of the comments from that post in the thread
  • Keyboard Navigation: Use the left and right arrow keys to navigate between posts
  • Subreddit Explorer: I've turned the top left subreddit dropdown menu into a list of subreddits based on category. There are currently about 1,000 subreddits listed here. It helps you discover new subreddits and waste even more time on reddit!
  • Download Images: Download all images and compress them into a zip. Done all on the client side. example
  • Widget embed codes: for reddit posts or subreddits details and examples below.
  • Same Styles everywhere: Option to use the same CSS styles from one subreddit all over reddit. I did this so I could use murica everywhere.
  • Subreddit Slideshow: Create a never ending slideshow from the images in a subreddit. Reddit Slideshow example

RedditJS is built with:

Post embed widget

You can add this script tag to any website. The post widget will embed itself onto your Wordpress post and detect if it has been posted to reddit. details and examples

<script src='//'></script>

If it has NOT been posted to reddit it will show a link to encourage the user to submit. no reddit post found

If it has been posted, it will load a widget displaying that reddit post giving the user where they can upvote/comment that post.

This is excellent for websites that have their content submitted to reddit.  It will help increase reddit activity with more upvotes and comments and allow the user to freely navigate reddit.
