Support running tsc --noEmit before transpiling

[aminya]

Feature request

It would be nice to add an option so that tsx runs tsc --noEmit before transpiling

Why?

Type-checking is important, and only relying on the IDE checker is not enough. The dependencies of a project change, and those can introduce new type errors. But because I haven't opened that file, the IDE doesn't check it.

Alternatives

Wrapping tsx so that it calls tsc --noEmit file before tsx

Blocking execution with type-checking kind of defeats the point of tsx. If you want to do that, why not just run tsc and use Node to run the compiled file?

Also, you can run this yourself:

tsc --noEmit ./file.ts && tsx ./file.ts

Or wrap it in a package.json script.
