@tsd/typescript v5.7.2
@tsd/typescript
TypeScript with some extras for type-checking.
This is a drop-in replacement for TypeScript meant for programmatic usage only. It does not expose the binaries like tsc
and tsserver
because it would override the TypeScript binaries of the project. It exposes extra methods on the internal TypeChecker
object.
Install
npm install --save-dev @tsd/typescript
