Run it yourself
What you need
- A checkout of the SDK repository and Node 22.23.3 or newer.
- Source and qualification only: the owner documents how to build and test it but no standalone run command.
Build and check it from source
- From the SDK repository root, run nvm use and npm ci, then npx playwright install chromium.
- Run npm run build; it includes npm run build:react-card-consumer.
- Run npx vitest run --config vitest.config.ts scripts/react-card-consumer.test.ts for the headless checks.
