Deno

Also known as: Deno / デノ

A JavaScript/TypeScript runtime redesigned by Node.js creator Ryan Dahl to fix architectural shortcomings. It features built-in security permissions, a standard library, URL imports, and edge deployment via Deno Deploy.


Overview

Deno is built on V8 and Rust and is secure by default — file, network, and environment access each require explicit flags. Its npm compatibility layer lets you reuse existing packages, and Deno 2.0+ significantly improved Node.js interoperability.

Edge Affinity

Deno Deploy runs functions at edge locations globally and integrates with frameworks like Hono and Fresh. It is a strong choice for security-sensitive enterprise APIs.
