We use >=yarn, keep in mind that we use lockfiles and use at least Node v12 to be able to build the project.

Install dependencies


For development run the following command, it will execute webpack and verdaccio to

yarn dev

The configuration file is located on tools/_config.yaml.

Run linting tooling and test to check your code is clean before commit.

⚠️ The development mode just emulate interaction of the UI development with a real verdaccio server, but it is not the real integration. UI is just a theme plugin dependency in the Verdaccio project.

Before commit

Don't forget run the following commands before commit and push your code, it will save you time.

yarn lint && yarn test


Remember we follow the the Conventional Commits specification.

End to End Testing

Additionally, we recommend run E2E testing before push and verify your changes do not break anything. These command will run in our CI anyway.

yarn build && yarn test:e2e

yarn build will build with webpack the production files.
