// Add theme options (if you want)
const options = {
  defaultFontFamily: 'Helvetica',
  headingFontFamily: 'Georgia',
  colors: {
    primary: {
      500: '#124C80',
    success: {

export default function Root() {
  return (
    // Wrap your components with <WuiProvider /> with your theme
      // Will inject a CSS reset with normalizer
      // Will show the focus ring on keyboard navigation only

Develop on local

  1. First install and build the packages (only the first time)
yarn first:install
  1. Start documentation website
yarn start
  1. Start a watch on all packages to rebuild them easily
yarn watch
  1. and go to https://localhost:3020

How to release

The release of the packages is automated by the CI, you just need to bump package version and push git tags to initiate the process.

Initiating the release process from your environment

The commands listed below will only prompt for packages to bump. Then they will modify packages versions, commit changes and create the git tag to finally push everything to github. No further actions are required once you have validated the packages to bump.

If you just need to bump one version without switching from a prerelease to stable release, run:

yarn release

To create a new prerelease, run:

This is only used for the first prerelease. If you already published a v5.0.0-alpha.0 then you just need to run the first command.

yarn prerelease

NB: you can replace alpha with any other keyword (beta, rc, ...)

Force publish a package

In addition to the options shown above, you can use the --force-publish option to force bumping some packages.


How to release when the publish process failed having published some packages

Re-run the failed job with ssh, then ssh into the machine and run this command:

cd welcome-ui/packages && find . -maxdepth 1 -type d \( ! -name . \) -exec bash -c "cd '{}' && npm publish" \;

This will publish each packages, those who are already published will fail and be ignored by the script.

How to rollback a release that has been stopped before publish to npm

Revert the last commit (which should be the commit that bumps package versions):

git revert HEAD^

Remove the tag on github and locally.

Then apply your fixes and re-run your release command.

About the CI

The CI will trigger on tags to build the packages and then push them to the npm registry
