Node.js 22.0 (Current) Released — The latest major version of Node is here. Note that it’s a ‘Current’ release for now, so gets all the newest features first, but is due to become Node’s main active LTS release this October. As an even numbered release, Node 22 should be around and maintained for a long time, most likely out to 2027 or so (see image above).

We’ll dig into some of what’s new with Node 22 in just a moment..

Stytch: Auth0 Alternative for AuthN, AuthZ, Fraud Prevention — Use Stytch for enterprise-grade multi-tenant B2B auth with SSO, RBAC, and SCIM. Use pre-built UIs, go headless, or integrate directly with the API. Plus, Stytch has device fingerprinting built-in to detect bots and prevent abuse. Get started free.

So what’s new in Node 22?

• V8’s Maglev compiler has been enabled by default, resulting in a performance boost for more short-lived programs.

• V8 has been updated to version 12.4 (which introduces iterator helpers, Set methods, and Array.fromAsync.)

• The ability to run npm scripts using

  1

  node

  itself, e.g.

  1	node --run test

• 1	node --watch

  is now stable.

• The previously experimental integrated WebSocket client is now enabled by default.

• require(esm) support. More on that next..

TypeScript 5.5 Beta — There’s a lot going on here (like inferred type predicates) but we’ll be focusing on it more in JavaScript Weekly. On the Node side, if you’re writing an ECMAScript module, you can now use named imports from TypeScript’s npm package.

JSR is Not ‘Another Package Manager’ — Node, npm and CommonJS brought a packaging standard to JavaScript, and while tools like Yarn or pnpm added their own twists to the process, Ryan says it’s time for a transformation. JSR is not ‘a new npm’ but a reshaping of how packages are distributed, designed for the ESM era.

File Loading — This isn’t a super new feature (it’s existed since Node 20.6.0) but a handy reminder that you can trim another dependency if you have basic

environment variable reading requirements.
