npm package

@bext-stack/tsc-rs ships a prebuilt tsc-rs binary through npm, so a JavaScript project can use the compiler without a Rust toolchain.

npm install --save-dev @bext-stack/tsc-rs

Use as a CLI#

npx tsc-rs --target es2022 --outDir dist src/index.ts

Use from a script#

The package exposes a helper that returns the path of the installed binary:

import { resolveBinaryPath } from "@bext-stack/tsc-rs/lib/resolve.mjs";
import { spawn } from "node:child_process";

const tscrs = resolveBinaryPath();
spawn(tscrs, ["--noEmit", "src/index.ts"], { stdio: "inherit" });

From there you can start the transpile pipe or the type-check daemon.

Supported platforms#

The binary comes from a per-platform optional dependency. npm, pnpm and yarn install only the one that matches the host.

On a platform without a prebuilt binary the shim fails with a clear error. Build from source and use the override below.

Override the binary#

Set TSCRS_PATH to the absolute path of a tsc-rs binary you built yourself. The npm shim uses it instead of the packaged binary:

TSCRS_PATH=/path/to/ts-rs/target/release/tsc-rs npx tsc-rs --version

The bext server resolves the compiler the same way: TSCRS_PATH first, then node_modules/.bin/tsc-rs found by walking up from the working directory.
