Hocuspocus would be nothing without its lively community. Contributions have always been and will always be welcome. Here is a little bit you should know, before you send your contribution:

Welcome examples

  • Failing regression tests as bug reports
  • Documentation improvements, e. g. fix a typo, add a section
  • New features for existing extensions, e. g. a new configurable option
  • Well explained, non-breaking changes to the core

Won’t merge

  • New extensions, which we then need to support and maintain

Submit ideas

Make sure to open an issue and outline your idea first. We’ll get back to you quickly and let you know if there is a chance we can merge your contribution.

Set up the development environment

It’s not too hard to tinker around with the official repository. You’ll need Git, Node and NPM installed. Here is what you need to do then:

  1. Copy the code to your local machine: $ git clone
  2. Install dependencies: $ npm install
  3. Build packages $ npm run build:packages
  4. Start the development environment: $ npm run start
  5. Open http://localhost:3000 in your favorite browser.
  6. Start playing around!

Compile and watch for changes:

npm run build:watch

How to include local hocuspocus packages in your development project

If you want to include a local hocuspocus package in your project, you'll need to follow the following steps. I have tried using npm link, but haven't managed to make it work reliably because of duplicated yjs imports. The following is the only way I made it work:

Execute the following command in this (hocupsocus) repo to compile the sources:

$ rollup -c -w

Then ..

$ cd other_project # execute the following commands within the other project that should include local
 # hocuspocus dependencies. Replace `provider` by the package that you want to replace.
 # Replace HOCUSPOCUS_LOCAL_REPO_PATH by the path of "this" repo.
$ rm -Rf node_modules/yjs node_modules/@hocuspocus/provider
$ ln -s HOCUSPOCUS_LOCAL_REPO_PATH/packages/provider node_modules/@hocuspocus/provider
$ ln -s HOCUSPOCUS_LOCAL_REPO_PATH/node_modules/yjs ./node_modules/yjs

Still doesn't work? -> rm -Rf node_modules && npm install ; then try again

Our code style

There is an eslint config that ensures a consistent code style. To check for errors, run $ npm run lint. That’ll be checked when you send a pull request, too. Make sure it’s passing, before sending a pull request.

Testing for errors

Your pull request will automatically execute all our existing tests. Make sure they all pass before sending a pull request. Your pull request will automatically execute all tests via the GitHub Workflow.

  • Start a redis server: $ docker run -d --name hocuspocus-redis -p 6379:6379 redis:7
  • Run all tests locally: $ npm run test
  • Run all tests of a single package: $ npm run test -- tests/PACKAGE_NAME
