Fandom Developers Wiki



You've landed at the Fandom Developers Wiki — but feel free to call us the Dev Wiki!

We’re Fandom’s premier destination for people who are looking to take a deep dive into coding. Whether you’re interested in exploring our code repository or finding a new feature for your home wiki, we’ve probably got a page or two you'll want to read. And there are lots of knowledgeable users around who are willing to lend a hand.

So take a few minutes to look around our front page. We think you’ll find something here that’ll help you make your part of Fandom just a bit more your own — just a little bit "cooler".

Going beyond JavaScript

You might think that Dev Wiki is just a place where JavaScript snippets are stored so that all Fandom wikis can use them.

But we do much more than that.

We provide useful code review to our fellow Dev Wiki contributors. (We don't like bugs any more than you do!) We offer translation services for the code you'll find here. We spitball the future by suggesting newer ways of looking at long-standing coding issues.

If you’re at all interested in how Fandom works under the hood, jump right in and start editing — even if you’re just asking a lot of questions!

Things we like

While we do a lot of things around here, there are probably three things in particular that Fandom users most often associate with the Dev Wiki.


Whether you want to request a JS feature, or you're looking for an existing one to add to your wiki, we've got you covered.


Like sculpting with CSS? We've got you covered.


Our users have made a ton of Lua modules for you to use when creating powerful templates.

Things to remember

Keep a couple of points in your mind when you’re coding here at Fandom.


Both CSS and JS can be either personal or site-wide. Personal code is that which affects your account only. Site-wide code applies to an entire wiki, such that all visitors will see its effect. Under Fandom’s customization policy, not all code is allowed to be site-wide, whereas you can do whatever you want with personal code.

MediaWiki docs

Did you know that the base MediaWiki software actually has documentation? Don't be ashamed if you don't! Instead, read the introduction on!
