Upgrade Paths

Migration guidance between major versions — breaking changes, effort estimates, and tips.

1.x 2.0 Medium Difficulty
Est. 2-4 hours

Breaking Changes

  • Global window variable removed (use globalThis)
  • Deno.run() removed (use Deno.Command)
  • Some std library APIs stabilized with breaking changes
  • Import map resolution changes
  • Unstable APIs promoted to stable or removed

Migration Notes

Deno 2.0 was designed to minimize breakage. Most 1.x code runs on 2.0. The biggest changes affect std library imports and deprecated APIs. deno lint helps find issues. The npm compatibility improvements in 2.0 may actually fix issues you had in 1.x.

Version Risk Assessment

Evaluate risk factors before choosing a version for production.

Version EOL Risk CVE Risk Ecosystem Cloud Support Overall Recommended Action
Deno 1.x High Low Maintenance Full High Upgrade to 2.0 — better npm compat, stable APIs
Deno 2.0+ None Low Active Full Low Current — keep updated with minor releases

Risk considers version currency, npm compatibility, and ecosystem momentum. Assessed as of March 2026.

Frequently Asked Questions

Common questions about Deno releases and lifecycle.

Should I use Deno or Node.js?
Node.js has a vastly larger ecosystem, more jobs, and more libraries. Deno offers better security defaults (permissions model), built-in TypeScript, and a more modern standard library. Use Deno for new projects where you want a batteries-included runtime. Use Node.js when you need maximum library compatibility.
Can Deno use npm packages?
Yes. Since Deno 1.28, you can import npm packages directly with npm: specifiers (e.g., import express from "npm:express"). Deno 2.0 made npm compatibility first-class with package.json support and node_modules creation. Most npm packages work, though native addons may not.
What is Deno Deploy?
Deno Deploy is a serverless edge runtime from the Deno team. Code runs close to users on 35+ global regions. Built on V8 isolates for fast cold starts. Supports Fresh (Deno web framework), Hono, and standard web APIs.
How does Deno handle security?
Deno is secure by default. Scripts cannot access the filesystem, network, or environment variables without explicit permission flags (--allow-read, --allow-net, etc.). This prevents supply chain attacks where a dependency does something unexpected.
Is Deno production-ready?
Yes. Deno 2.0 (Oct 2024) marked the production-ready milestone with full backward compatibility, stable APIs, npm compatibility, and long-term support commitment. Companies like Slack, GitHub, and Netlify use Deno in production.
