What is Deno?

Deno is a secure JavaScript and TypeScript runtime built on V8 and Rust, created by Ryan Dahl (the original creator of Node.js). It runs TypeScript natively without a compilation step, has secure-by-default sandboxing, and implements modern web standard APIs. Deno 2 brings full Node.js and npm compatibility.

            🚀 Why Latest Versions Matter: Deno is actively developed with major improvements in each release, including enhanced Node.js/npm compatibility, performance improvements, and new web platform API implementations. Latest versions include critical security patches and improved TypeScript support.

📋 Available Deno Packages

debian.griffo.io provides two different Deno packages to suit different needs:

🦕 deno (Recommended)

Full Deno runtime with all developer tooling including the REPL, LSP, formatter, linter, test runner, and bundler. This is the recommended choice for most developers.

⚡ denort

Lightweight Deno runtime without the developer tooling. Ideal for production deployments where you only need to run compiled Deno programs with minimal overhead and a smaller binary footprint.

sudo apt install denort

🔄 Managing Both Packages

You can install both deno and denort simultaneously:

Install both:

sudo apt install deno denort

Check deno version:

deno --version

Check denort:
