+DolphinScheduler uses `pnpm` to check and automatically fix frontend code style and formatting issues.
+First, navigate to the frontend project directory:

+```shell
+pnpm run lint      # Fix ESLint issues
+pnpm run prettier  # Format code
+```

+Finally, you can run the following command to perform a full TypeScript type check and catch type-related errors early:
+
+```shell
+pnpm exec vue-tsc --noEmit  # Type check
