Frequently Asked Questions

How often does Deno release new versions?

Deno ships minor versions roughly monthly and patch releases as needed. Major versions ship when significant breaking changes are ready (Deno 1.0 in 2020, Deno 2.0 in October 2024).

Can I use npm packages with Deno?

Yes. Since Deno 2.0, you can import npm packages using 'npm:' specifiers (e.g., import express from 'npm:express'). Most npm packages work out of the box, including those with native dependencies.

Should I use Deno or Node.js for a new project?

Node.js has the larger ecosystem and more production battle-testing. Deno offers better defaults (TypeScript, security permissions, built-in tooling) and a cleaner API. For new projects where you want modern defaults, Deno 2.x is a strong choice. For maximum library compatibility, stick with Node.js.
