User interface classes built on the OOjs framework.


OOjs UI is a modern JavaScript UI toolkit for browsers. It provides a library of common widgets, layouts and windows that are ready to use, as well as many foundational classes for constructing custom user interfaces. The library was originally created for use by VisualEditor, which uses it for its entire user interface, and is now completely independent, and more useful and convenient for other use cases.

This library is available as an npm package! Install it right away:

npm install oojs-ui

If you don't want to use npm, you can:

  1. Clone the repo, git clone https://git.wikimedia.org/git/oojs/ui.git.

  2. Install Grunt command-line utility:
    $ npm install -g grunt-cli

  3. Install dev dependencies and build the distribution files:
    $ npm install

  4. You can now copy the distribution files from the dist directory into your project.

  5. You can see a suite of demos in /demos by executing:
    $ npm run-script demos

We use the Semantic Versioning guidelines as much as possible.

Releases will be numbered in the following format:


For more information on SemVer, please visit http://semver.org/.

Found a bug or missing feature? Please report it in the issue tracker!

Release process:

$ cd path/to/oojs-ui/
$ git remote update
$ git checkout -B release -t origin/master

Ensure tests pass

$ npm install && composer update && npm test

Avoid using "npm version patch" because that creates

both a commit and a tag, and we shouldn't tag until after

the commit is merged.

Update release notes

Copy the resulting list into a new section at the top of History.md and edit

into five sub-sections, in order:

* Breaking changes

* Deprecations

* Features

* Styles

* Code

$ git log --format='* %s (%aN)' --no-merges --reverse v$(node -e 'console.log(require("./package.json").version);')...HEAD | grep -v "Localisation updates from" | sort $ edit History.md

Update the version number

$ edit package.json

$ git add -p $ git commit -m "Tag vX.X.X" $ git review

After merging:

$ git remote update $ git checkout origin/master $ git tag "vX.X.X" $ git push --tags $ npm publish
