Getting started

1. We use Node.js 18 and Yarn. See https://nodejs.org/en/download/ for options for installing Node.js.
2. Install "unplugged" dependencies.

yarn install

3. Start development server, which will report any lint violations as well:

yarn start

4. Open http://localhost:3000 in a browser.

Testing

Run unit tests with:

yarn test

Code style and linting

• ESLint is automatically run on commits via a pre-commit hook. To skip the pre-commit hook, use git commit --no-verify.
• To attempt to automatically resolve lint issues, run yarn lint from the repo's root directory. ESLint will fix whatever issues it can and report any that must be manually resolved.
• In an IDE other than IntelliJ (VS Code, etc): install the eslint plugin from your package manager, and there should be a command to fix issues at any time.
• In IntelliJ:
  • Styles should be automatically applied by .editorconfig; make sure you've also turned on eslint.
  • In order to correctly format a file at any time, run the IntelliJ Reformat Code action, and then right-click in a window and click Fix ESLint Problems. You could also create an IntelliJ macro to do this for you as explained here, and map running of the macro to a keyboard shortcut for convenience.
