Is vue-tsc a full replacement of tsc?

[jods4]

The README mentions doing a type-check only with --noEmit and then using vite for regular build.
Is vue-tsc a full, compatible, typescript compiler though?

Can I build a basic project on the CLI using vue-tsc without the "no emit" flag?

More interestingly: can I use it as a custom TSC compiler in loaders such as rollup-plugin-typescript2?

Some background / context:

• I have a Vite build that is customized to use the offical tsc compiler instead of esbuild (main reason being const enum support).
• The build uses rollup-plugin-typescript2 to achieve that, which has an option to use a specific compiler.
• The awesome Volar types can't be injected into regular tsc, so I'm left with 2 options if I want to typecheck my project:
• (1) do 2 passes, vue-tsc --noEmit && vite build, which would in my case go through TS compiler twice, so that's a bit of a bummer speedwise, but it'd work;
• (2) swap vue-tsc for typescript in rollup-plugin-typescript2, hoping it would compile and do the full typechecking magic.

I suppose (2) would require some fiddling with the vue rollup plugin, which compiles SFC files, so that each plugin sees the correct input. Otherwise rollup-plugin-typescript2 sees already compiled .vue files and that would ruin the vue-tsc magic.

Sorry I don't know how rollup-plugin-typescript2 working for now, I will give you answer in future.
