Codex is the design system for Wikimedia. The Codex repository contains four packages:

• Components: for building usable, accessible, translatable applications. Codex contains Vue 3 components and CSS-only components
• Design tokens: for writing styles consistent with the Codex Design Style Guide for Wikimedia
• Icons: a collection of icons with language and directionality variants
• VitePress site: for Codex documentation, Vue component demos, and design token visualization

Codex features:

• Wide-ranging support for internationalization and global usage
• Web accessibility compliant (Web Content Accessibility Guidelines 2.1 level AA)
• Comprehensive browser and device support

To install:

npm install --save-dev @wikimedia/codex @wikimedia/codex-icons

To use components:

import { CdxButton, CdxTextInput } from '@wikimedia/codex';

To use icons:

import { cdxIconAlert, cdxIconNewWindow } from '@wikimedia/codex-icons';

For more information on how to set up and use the library, see the usage documentation.

Codex development requires the following:

• Node: the required version is pinned in .nvmrc. To install and use the required version of Node, run nvm install "$(<.nvmrc)" then nvm use in the root of the repository.
• npm: version 7 or higher is required to support workspaces; it is not included by default in older versions of Node (prior to version 15) and will need to be upgraded manually. You can do this with nvm via nvm install --latest-npm.

Helpful commands:

• npm install in the root of the repository to install requirements for all workspaces
• npm run doc:dev to start the docs site
• npm run dev to start the Vite sandbox
• npm run test:unit -w @wikimedia/codex to run unit tests for e.g. the codex workspace. Read more about testing.
