Deno

Deno is a simple, modern and secure runtime for JavaScript and
TypeScript that uses V8 and is built in Rust.

Features

• Secure by default. No file, network, or environment access, unless explicitly
  enabled.
• Supports TypeScript out of the box.
• Ships only a single executable file.
• Built-in utilities.
• Set of reviewed standard modules that are guaranteed to work with
  Deno.

Getting Started

Try running a simple program:

deno run https://deno.land/std/examples/welcome.ts

Or a more complex one:

const listener = Deno.listen({ port: 8000 });
console.log("http://localhost:8000/");

for await (const conn of listener) {
  serve(conn);
}

async function serve(conn: Deno.Conn) {
  for await (const { respondWith } of Deno.serveHttp(conn)) {
    respondWith(new Response("Hello world"));
  }
}

You can find a deeper introduction, examples, and environment setup guides in
the manual.

The complete API reference is available at the runtime
documentation.
