* Migrate build toolchain from ncc/Jest to esbuild/Vitest
Replace the legacy ncc/Jest/Babel build stack with a modern ESM toolchain:
Build:
- Replace @vercel/ncc with esbuild (--platform=node --target=node20 --format=esm)
- Add createRequire banner for CJS interop in ESM bundle
- Add "type": "module" to package.json
- Add tsc --noEmit typecheck script (esbuild strips types without checking)
- Add typecheck to husky pre-commit hook
Dependencies:
- Bump @actions/core@3, exec@3, io@3, tool-cache@4 (ESM-only)
- Replace jest/ts-jest/@babel/* with vitest@4
Tests:
- Convert 29 test files: jest.fn()→vi.fn(), jest.mock()→vi.mock(), jest.spyOn()→vi.spyOn()
- Fix vitest 4 compat: mockImplementation requires args, mock call tracking, await .rejects
CI:
- Update build step from ncc build → npm run build
- Update composite action to use npm run build
* Switch tsconfig to NodeNext module resolution
Change module/moduleResolution from ES2022/bundler to NodeNext/NodeNext
and target from ES2022 to ES2020.
- Add .js extensions to all relative imports across 59 source/test files
(required by NodeNext module resolution)
- Add vitest/globals to tsconfig types array for global test API declarations
In Typescript/Javascript an empty string split on newline is going to
produce an array with an empty string.
=> "".split('\n')
[""]
This causes the action to produce a warning, unless `pull-images` is set
to false.
Failed to get dockerfile path for image : Error: The process '/usr/bin/docker' failed with exit code 1
Filtering the list to remove any zero-length strings from the array
solves this issue.
