tsrun

A TypeScript interpreter written in Rust, designed for embedding in applications.

Overview

tsrun executes TypeScript code directly without transpilation to JavaScript. It uses a register-based bytecode VM for efficient execution. Type annotations are parsed but stripped at runtime (no type checking).

Features

• ES modules with import/export
• Async/await and Promises
• Classes with inheritance and static blocks
• Generators and iterators
• Destructuring and spread operators
• Template literals
• Full set of built-in objects: Array, String, Object, Map, Set, Date, RegExp, JSON, Math, and more

Installation

cargo install tsrun

Usage

tsrun script.ts

Library Usage

use tsrun::Runtime;

fn main() {
    let mut runtime = Runtime::new();
    let result = runtime.execute("const x = 1 + 2; x").unwrap();
    println!("{:?}", result);
}
