Quick Start

Deno Deploy natively executes TypeScript without any build step or compilation required. It isolates tenants using V8 isolates, providing incredible speed and security.

deloyctl deploy --project=my-project main.ts

Production Patterns

Deno KV

Use Deno KV for global, strongly consistent database storage built directly into the runtime. It requires zero configuration and provides ACID transactions.

Architecture & Scaling

Web Standard Modules

Deno completely ignores Node.js node_modules and package.json. You import modules directly via URLs (e.g., import { serve } from 'https://deno.land/std/http/server.ts').

Error Recovery

Deno strictly adheres to web standards. If an unhandled promise rejection occurs, the V8 isolate crashes. Always await and catch asynchronous network calls.

Security Notes

Deno is secure by default. Even when running locally, it cannot access the disk, network, or environment variables unless you explicitly pass flags (e.g., --allow-net).
