Running the Project Locally

1. To install dependencies, run the following:

npm install

2. To install the Comet CLI, run the following (optional):

npm install -g @metrostar/comet-cli

3. Install Recommended VS Code Extensions (optional)

4. To run locally with SSO, add a file called .env.local to the comet-starter directory. Copy and paste the template below and replace the placeholder values with your own (optional):

VITE_SSO_AUTHORITY=[SOME_KEYCLOAK_REALM_URL] # Ex: http://localhost:8088/realms/dev
VITE_SSO_CLIENT_ID=[SOME_CLIENT_ID] # Ex: dev-client

5. To start the app, run the following:

npm run dev

Running Unit Tests

To make sure your changes do not break any unit tests, run the following:

npm run test

Ensure to review the coverage directory for code coverage details.

npm run test:coverage

Running Code Quality Checks

To make sure your changes adhere to additional code quality standards, run the following:

npm run lint
npm run format

You can also see the .vscode/settings.json file to find how to enable auto-formatting on save.

Running End-to-End (E2E) Tests

Note: running E2E tests requires a deployed or running app.

1. To run against a deployed app, add the following to your .env.local (optional):

VITE_BASE_URL=SOME_URL # Ex: 'https://metrostar.github.io/comet-starter/'

2. To install playwright dependencies, run the following (only required the first time):

npx playwright install

3. To run e2e tests, run the following:

npm run e2e

Running Accessibility (a11y) Tests

Note: running accessibility tests requires a deployed or running app.

1. To run against a deployed app, add the following to your .env.local (optional):

VITE_BASE_URL=SOME_URL # Ex: 'https://metrostar.github.io/comet-starter/'

2. To run accessibility tests, run the following:

npm run a11y
