REX Language
Overview
A TypeScript-shaped language that compiles to TypeScript — with real Cursor and VS Code IntelliSense.
REX is our studio language: TypeScript-like surface, compiles to TypeScript, lives in the editor with highlighting, diagnostics, completions, and go-to-definition.
Namespaces, lighter module sugar, CLI and Vite plumbing — infrastructure we can evolve without leaving the TypeScript ecosystem. Actively developed and already part of how we ship.
