Installation
Multiple ways to use tsrun in your projects
Quick Example
Run TypeScript code from Rust in just a few lines
use tsrun::{Interpreter, StepResult};
fn main() -> Result<(), tsrun::JsError> {
let mut interp = Interpreter::new();
interp.prepare(r#"
class User {
constructor(public name: string, public email: string) {}
greet() { return `Hello, ${this.name}!`; }
}
new User("Alice", "alice@example.com").greet()
"#, None)?;
loop {
match interp.step()? {
StepResult::Continue => continue,
StepResult::Complete(value) => {
println!("{}", value.as_str().unwrap()); // "Hello, Alice!"
break;
}
_ => break,
}
}
Ok(())
