OOUI

OOUI is a component-based JavaScript UI library. Key features:

• Common widgets, layouts, and dialogs
• Classes, elements, and mixins to create custom interfaces
• Internationalization and localization, like right-to-left (RTL) languages support
• Theme-ability
• Built-in icons
• Accessibility features

It is the standard library for Web products at the Wikimedia Foundation, having been originally created for use by VisualEditor.

Quick start

The library is available on npm. To install:

$ npm install oojs-ui

Once installed, include the following scripts and styles to get started:

<script src="node_modules/jquery/dist/jquery.min.js"></script>
<script src="node_modules/oojs/dist/oojs.min.js"></script>
<script src="node_modules/oojs-ui/dist/oojs-ui.min.js"></script>
<script src="node_modules/oojs-ui/dist/oojs-ui-wikimediaui.min.js"></script>

Loading the library

While the distribution directory is chock-full of files, you will normally load only the following three:

• oojs-ui.js, containing the full library;
• One of oojs-ui-wikimediaui.css or oojs-ui-apex.css, containing theme-specific styles; and
• One of oojs-ui-wikimediaui.js or oojs-ui-apex.js, containing theme-specific code

You can load additional icon packs from files named oojs-ui-wikimediaui-icons-*.css or oojs-ui-apex-icons-*.css.

The remaining files make it possible to load only parts of the whole library.

Furthermore, every CSS file has a right-to-left (RTL) version available, to be used on pages using right-to-left languages if your environment doesn't automatically flip them as needed.

Contributing

We are always delighted when people contribute patches. To setup your development environment:

1. Clone the repo: $ git clone https://gerrit.wikimedia.org/r/oojs/ui oojs-ui

2. Move into the library directory:
   $ cd oojs-ui

3. Install composer and make sure running composer will execute it (e.g. add it to $PATH in POSIX environments).

4. Install dev dependencies:
   $ npm install

5. Build the library (you can alternatively use grunt quick-build if you don't need to rebuild the PNGs):
   $ grunt build

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

7. You can also copy the distribution files from the dist directory into your project.

We use Gerrit for code review, and Phabricator to track issues. To contribute patches or join discussions all you need is a developer account.

• If you've found a bug, or wish to request a feature raise a ticket on Phabricator.
• To submit your patch, follow the "getting started" quick-guide. We try to review patches within a week.
• We automatically lint and style-check changes to JavaScript, PHP, LESS/CSS, Ruby and JSON files. You can test these yourself with npm test and composer test locally before pushing changes. SVG files should be squashed in advance of committing with SVGO using svgo --pretty --disable=removeXMLProcInst --disable=cleanupIDs <filename>.

A new version of the library is released most weeks on Tuesdays.

Release

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 && composer test

    # 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 (change 'patch' to 'minor' if you've made breaking changes):
    $ npm version patch --git-tag-version=false

    $ 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"
    $ npm run publish-build && git push --tags && npm publish
