Run all local quality gates for the affected library. If no argument provided, detect the library from changed files via git diff --name-only.
Steps
1. Identify scope
# If $ARGUMENTS provided, use it. Otherwise detect from changed files:
git diff --name-only HEAD~1
Map changed file paths to library names (libs/core/ → core, libs/platform/ → platform, etc.).
2. Format
yarn format
Ensure all code is formatted before running quality gates.
3. Build
nx run <library>:build
Report: PASS or FAIL with error summary.
4. Lint
nx run <library>:lint
Report: PASS or FAIL with violation count and top issues.
5. Unit tests
nx run <library>:test --skip-nx-cache
Report: PASS or FAIL with failing test names and error messages.
6. Export check
For each changed component file, verify it is exported from the library's public_api.ts or index.ts. Flag any new public classes missing from exports.
7. Breaking change check
Run git diff on changed files. Flag:
- Removed
input(),output(), ormodel()declarations - Renamed exported classes, functions, or types
- Changed input/output names
- Changed default values
If breaking changes found, verify the commit message contains BREAKING CHANGE: footer.
