Usage

yarn build
- This babelfies all of the packages and creates/lib
folders for each one. -
yarn test
- Run all linting and unit tests before committing. -
yarn test -o
- Run only the tests that have changed. -
yarn test -u
- Update all of the snapshot tests.
Lerna
-
lerna changed
- Show which packages have changed. -
lerna diff
- Show specifically what files have cause the packages to change.
Linking
When linking inside of the Monorepo, everything works as expected. If you are trying to consume packages from this Monorepo in a different application locally, using npm link
or yarn link
does not work as expected. However, we have a workaround for the time being.
- Run
yarn build
- Run
yarn dev
- Change the
package.json
of the consumer from$YOUR_PACKAGE_NAME
(which lives inside the monorepo) tofile:./../monorepo/packages/$YOUR_PACKAGE_NAME
- Run
rm -rf node_modules && yarn
in the consumer 🎉
Contributing
All formatting and linting should be taken care of for you using stylelint, ESLint, and Prettier. You should also consider installing an extension for CSS syntax highlighting.
