Build Status - Cirrus Twitter handle

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


  • 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 like a dependency inspector (deno info) and a code formatter (deno fmt).
  • Set of reviewed standard modules that are guaranteed to work with Deno.


Shell (Mac, Linux):

curl -fsSL | sh

PowerShell (Windows):

iwr -useb | iex

Homebrew (Mac):

brew install deno

Chocolatey (Windows):

choco install deno

Build and install from source using Cargo:

cargo install deno

See deno_install and releases for other options.

Getting Started

Try running a simple program:

deno run

Or a more complex one:

import { serve } from "";
const s = serve({ port: 8000 });
for await (const req of s) {
  req.respond({ body: "Hello World\n" });

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

More in-depth info can be found in the runtime documentation.
