Use Babel 7 TS compilation and forked checker? #151

Open karlhorky opened 5 years ago

karlhorky commented 5 years ago

Current Behavior

TypeScript is both compiled and checked by rollup-plugin-typescript2.

Desired Behavior / Suggested Solution / Alternatives

What are your thoughts on adding something to run type-checking code in a separate process, like fork-ts-checker-webpack-plugin?

Looks like this would either require moving away from Rollup or finding a plugin that does this.

Who does this impact? Who is this for?

Additional Information

create-react-app did some exploration into improving TS performance in this thread, when they were adding fork-ts-checker-webpack-plugin: https://github.com/facebook/create-react-app/pull/5903
Next.js recently added fork-ts-checker-webpack-plugin too https://github.com/zeit/next.js/pull/7278

Ah it looks like there is an issue in the rollup-plugin-typescript2 repo that is asking for this feature: https://github.com/ezolenko/rollup-plugin-typescript2/issues/113

So that may be a possible solution, in case that gets implemented.
