scriptc

Compile ordinary TypeScript and JavaScript to small, fast native executables — no Node, no V8, no JavaScript engine in the binary. What compiles behaves byte-for-byte like Node.

$ cat fib.ts
function fib(n: number): number {
  return n < 2 ? n : fib(n - 1) + fib(n - 2);
}
console.log(fib(30));

$ scriptc run fib.ts
832040

$ scriptc build fib.ts -o fib && ./fib
832040

Install

$ npm install -g scriptc

Requires clang on the PATH (Xcode Command Line Tools on macOS, clang package on Linux).

Commands

• scriptc build <file.ts> — compile to a native executable
• scriptc run <file.ts> — compile and run
• scriptc coverage <file.ts> — what compiles statically, and why the rest doesn't

No annotations, no dialect, no special stdlib: the same TypeScript you run on Node, type-checked by the real TypeScript compiler. Programs outside the static tier can opt into --dynamic, which embeds a small JavaScript engine (~620KB) for the parts that can't be static; everything else fails the build with a specific error code and usually a rewrite hint.

Native code can be called through an explicit, link-time C ABI manifest: declare the function signature in TypeScript, bind it to a C symbol, and build with --ffi <manifest.json>. See the Native FFI guide.
