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.
npm install --save-dev @tsd/typescript
This package is just TypeScript with some private methods exposed that tsd needs for enhanced type checking.
