VA Mobile Design System - Components Package

The Components package is the core of the VA Mobile Design System containing the components themselves.

For Consumers

The components package assumes you already have a functioning React Native app, whether using Expo or React Native CLI; see the React Native documentation if you do not.

Once you have a running app:

  1. Add @department-of-veterans-affairs/mobile-component-library as a dependency with your package manager (e.g. yarn)
  2. Add @department-of-veterans-affairs/mobile-assets as a dependency
    • Note: beyond the assets package, react, react-native, and react-native-gesture-handler are also expected dependencies to run the components package
  3. Hook up the custom fonts in the assets package to your app
  4. Import components from @department-of-veterans-affairs/mobile-component-library within .jsx/.tsx files and incorporate into the display logic similarly to how you would the built-in React Native components

Note: The linting package is highly recommended so you'll automatically receive linting warnings for deprecation as the components package evolves; it should be set to the same version as the components package.

Documentation about components available can be found via the documentation site as well as our Storybook. Questions and issues can be directed to our DSVA Slack channel.
