Codex

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

Quick start

Usage

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.

Development

Codex development requires the following:

• Node: the required version of Node is pinned in .nvmrc. To install and use the required version, run nvm install "$(<.nvmrc)" then nvm use in the root of the repository. Node Version Manager (NVM) is a handy tool that lets you install and switch between multiple versions of Node on your machine. This is especially useful when working on multiple projects that depend on different Node versions.
  Learn more about NVM on GitHub.
• npm: version 7 or higher is required to support workspaces. You can install latest version of npm 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.
