Deno Extension

If you're not familiar with Deno, it's a runtime for JavaScript and TypeScript started by the creator of Node.js.

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.

curl -fsSL https://deno.land/install.sh | sh

Getting Started

Try running a simple program:

deno run https://deno.land/std/examples/welcome.ts
Enter fullscreen mode Exit fullscreen mode

Or a more complex one:

const listener = Deno.listen({ port: 8000 });
console.log(
Enter fullscreen mode Exit fullscreen mode

Tonight I discovered there is a VS Code extension for Deno that adds support for the Deno language server.

You can read more about getting VS Code setup for Deno in the official docs.
