List of community extensions?

This link List of Extensions only provides the list of official extensions.

There are some great community extensions that are hard to find because they aren’t listed under a single resource. Some good ones are demoed here: React CodeMirror - CodeMirror component for React.
Repl.it which is a commercial supporter of codemirror has also published several extensions.

If the official codemirror website can have a section linking to various community extensions, it will make finding, contributing, and sharing such extensions much more straightforward.

@marijn would you be willing to create an official page to list community extensions - I would love to help you collect the list!

Something like this is definitely going to be useful. I’m somewhat concerned about maintaining it, though. Many open-source packages are published in a short burst of enthusiasm and then immediately abandoned, and I’d hate to end up with a lot of links to inactive, broken stuff—but I also don’t really want to audit every link and check on it later.

A disclaimer at the top + an encouragement to help maintain the list with pull requests might make this manageable, I don’t know. If you have a set of links that’d make a good starting list, please post them here and I’ll set up an initial page.

Thanks! That would be lovely.

Given how widespread codemirror is, I’m sure that the community will pick up once they have an official channel for listing the plugins.


Here are a few of the initial extensions & components. Please start with a page for listing these and I will send your PRs on github as I hunt for more.

Note: all of the following rely on codemirror v6

And here are some for older versions - in case someone would like to port them to codemirror 6

Ideally, creating a separate page for these will be good since this will help people find older things that need to be ported to the latest version of codemirror.

Contributing my own extensions. I guess @lqv/codemirror would go under Extensions and @lqv/codebooth would go under Components, maybe?

@lqv/codemirror, @lqv/codebooth

These packages allow you to create interactive coding tutorials by recording typing into a CodeMirror editor and then replaying it. @lqv/codemirror is a low-level package that handles recording and replaying. @lqv/codebooth builds on this, providing a family of React components (<Editor>, <FileTabs>, etc.) for building an IDE-like experience.

Looks great! Thanks :smile:

@marijn would you like the extensions compatible only with older versions of codemirror to also go on that page? If not, where shall we put those?

No. I don’t really want to maintain such a page at this point.
