rscute

A lightweight, SWC-powered TypeScript JIT runner for Node.js.

The name comes from RS (Rust, via SWC) + cute (execute) — nimble, lightweight, smart execution. rscute intercepts module imports on-the-fly and compiles TypeScript files on-demand — zero config, zero build step.

Features

• Runs .ts, .tsx, .cts, and .mts files instantly via a zero-config CLI
• Intercepts module resolutions on-the-fly and loads dependencies on-demand
• Resolves tsconfig.json path mappings automatically
• Supports both CJS and ESM projects seamlessly

Quick Start

Installation

npm i -D rscute

Note: If you are using pnpm, run commands using pnpm exec instead of npx.

CLI Execution

npx rscute script.ts

Program

rscute/register

Use the register API to hook TypeScript compilation into Node.js module resolution programmatically.

const { register } = require('rscute/register');

register();

// Now you can require .ts files directly
require('./my-module.ts');
