OpenWorkers Runtime Boa

Pure Rust JavaScript runtime for serverless workers, built on Boa.

Quick Start

use openworkers_runtime_boa::{Worker, Script, Event, HttpRequest, HttpMethod, RequestBody};
use std::collections::HashMap;

let script = Script::new(r#"
    addEventListener('fetch', event => {
        event.respondWith(new Response('Hello from Boa!'));
    });
"#);

let mut worker = Worker::new(script, None).await?;

let req = HttpRequest {
    method: HttpMethod::Get,
    url: "http://localhost/".to_string(),
    headers: HashMap::new(),
    body: RequestBody::None,
};

let (task, rx) = Event::fetch(req);
worker.exec(task).await?;

let response = rx.await?;
