fix(@formatjs/ts-transformer): restore ts-jest-integration subpath export (#6437)

longlho · claude · web-flow · commit 10d1f740972d · 2026-04-24T18:11:53.000Z
## Summary - Add `./ts-jest-integration.js` to the `exports` field in `package.json` - Add `ts-jest-integration.ts` as a rolldown entry point in `BUILD.bazel` so it gets bundled with `.js`, `.d.ts`, and `.js.map` into the published package - Update jest integration test config to use `.js` extension in the import path This was a regression from #6080 which added an `exports` field to `package.json` but only included `.` — blocking the `ts-jest-integration` deep import that ts-jest users rely on. Closes #6433 ## Test plan - [x] `bazel test //packages/ts-transformer:package_exports_test` — validates all exports resolve to real files - [x] `bazel test //packages/ts-transformer:unit_test` — 27 tests pass - [x] All pre-commit hooks pass 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
