Deno
Deno is a modern runtime for JavaScript, TypeScript, and WebAssembly with secure defaults, built-in developer tooling, and direct npm package compatibility.
When to Use
- Secure TypeScript/JavaScript Server Runtime: Default-secure environment requiring explicit file, network, and environment permissions.
- Edge Functions & Cloudflare/Deno Deploy: Sub-millisecond cold start serverless endpoints and web APIs.
- Zero-Config Scripting & Tooling: Running scripts directly without
npm install,tsconfig.json, or bundlers. - Standard Web APIs & Deno 2 Ecosystem: Utilizing standard
fetch, WebSockets, and seamless npm package compatibility.
