Build Frontend Skill
Use this skill to validate that all frontend TypeScript and React components compile successfully without errors.
What This Skill Does
- •Runs
npm run buildinsrc/client/frontend/ - •Validates TypeScript compilation via
tsctype checking - •Bundles React application with Vite
- •Captures and parses build errors
- •Reports errors with file and line number references
- •Exits with failure status if any build errors are found
When to Use
- •After implementing or modifying React components
- •After updating frontend TypeScript types or interfaces
- •To validate that TypeScript compilation succeeds
- •Before running E2E validation against the UI
- •To ensure Vite bundling produces valid output
How the Agent Should Use This Skill
- •Prepare: Ensure you are in the repository root directory
- •Invoke: Run the frontend build helper script from the repository root:
code
dotnet .github/skills/build-frontend/build-frontend.cs
- •Parse Output: Monitor stdout for success message and stderr for errors
- •Handle Errors: If exit code is non-zero, the build failed. Review the error messages to identify:
- •TypeScript compilation errors (e.g., type mismatches, missing properties)
- •Import/export issues
- •React component rendering errors
- •Vite bundling failures
- •Report: If any errors occur, halt further validation and report the build error details to the user
Success Criteria
- •Exit code: 0
- •Stdout contains:
[BUILD] Frontend build completed successfully
Failure Indicators
- •Exit code: 1
- •Stderr contains TypeScript or build errors
- •Error messages may reference file paths, line numbers, and error codes (e.g.,
TS7006)
Notes
- •The build script automatically finds the repository root by searching for
FakeSurveyGenerator.slnxorFakeSurveyGenerator.sln - •Frontend directory is located at
src/client/frontend/ - •Build process includes TypeScript type checking (
npm run buildruns bothtsccheck and Vite bundling) - •The script automatically runs
npm ciifnode_modulesdirectory is missing, ensuring dependencies are installed before building - •On Windows, the script uses
cmd.exe /c npmto reliably invoke npm, avoiding PATH resolution issues
Next Steps After Success
Once frontend build succeeds, typically invoke:
- •Validate Aspire Runtime Skill - to start the application and UI server
- •Validate E2E Skill - to run interactive UI tests with Playwright MCP
