2024년 5월 30일 작업일지

아침에 일어나자마자 피부터 뽑고 왔다.

SWC 배포 fix

• https://github.com/swc-project/swc/commit/797b90bc88f121087efde3bb6b5a168de41e1661

겨우 고쳤다. 근데 JS API 고치다가 한번 더 깨져서 다시 고치고 새 버전 배포했다.

터보팩RcStr 최적화 PR

• https://github.com/vercel/turbo/pull/8221

• https://github.com/vercel/next.js/pull/66262

많은 노가다 작업을 했다. 벤치마크를 돌릴 수 있을 정도의 작업이 진행돼서 돌려봤는데 성능 차이는 생각보다 작았던 것 같다.

SWC JS API 복구

• https://github.com/swc-project/swc/pull/8998

JS API가 깨져서 복구했다.

SWC X 시작

• https://github.com/swc-project/swc/pull/8999

내가 구상중인 cross-module JS 최적화 도구다. 번들러들에서 쓸 수 있는 형태로 배포하고 추후에 안정화되면 터보팩에도 넣을 생각이다.

SWC Output API 구상

• https://github.com/swc-project/swc/pull/9000

트랜스폼에서 JS한테 데이터를 돌려주기 위한 API에 대해 고민했다.

SWC CI 개선

• https://github.com/swc-project/swc/pull/9002

문제가 생겨서 임시로 비활성화했던 CI 작업들을 활성화했다.
