Resolves persistent `ReferenceError: exports is not defined` errors
encountered during unit tests (`unit-test (20.x)` job) in the GitHub
Actions CI environment. These errors occurred specifically when
importing `cli-testing-library` in the global Jest setup file
(`test/jest-setup.ts`), despite tests passing locally with the same
Node.js version (v20.19.0).
After iterative testing, the following Jest configuration combination
was identified as necessary to ensure consistent ESM handling and test
success in both local and CI environments:
- Set preset to `ts-jest/presets/default-esm` for stricter ESM rules.
- Configured `transformIgnorePatterns` to ensure Jest transforms specific ESM dependencies (`cli-testing-library`, `@clack`, `cleye`) within `node_modules`.
- Expanded the `transform` pattern (`^.+\\.(ts|tsx|js|jsx|mjs)$`) to explicitly cover various script types handled by `ts-jest`.
- Included explicit `tsconfig` overrides (`module: 'ESNext'`, `target: 'ES2022'`) within the `ts-jest` transform options to resolve potential environment discrepancies.
- Retained `moduleNameMapper` for `.js` imports for reliable module resolution.
- Ensured `cli-testing-library` imports remain in the global setup (`test/jest-setup.ts`).
- Removed test cache clearing from the `test:unit` script in `package.json`.
This configuration now passes reliably across environments.
fix(prepare-commit-msg-hook.ts): add missing await keyword to getStagedFiles() function call
feat(prepare-commit-msg-hook.ts): add spinner to indicate commit message generation progress
feat(utils/mergeDiffs.ts): add mergeDiffs function to merge array of strings into an array of strings with a maximum length
The test.ts file is now ignored by git. The missing await keyword has been added to the getStagedFiles() function call. A spinner has been added to indicate the progress of commit message generation. The mergeDiffs function has been added to merge an array of strings into an array of strings with a maximum length.
