commover v1.0.0

commover

Batch remove unused @ts-expect-error directive comment lines, especially helpful when using with ts-migrate.

What does commover mean? It's a composite word that represents comment remover ahahaha :)

Motivation

ts-migrate is such an useful tool that helps us fix historical TS errors incrementally in our projects. But sometimes it's not perfect as well for some reason. There're lots of unused @ts-expect-error directive added to the code, which causes TS compile errors.

This project is designed for this, which will read your compile log, parse and remove the corresponding lines.

pnpm install -g commover # or npm/yarn

commover tsc.log # will read `tsc.log` and handle parsed errors as need
