How V8 is Making JSON.stringify More Than Twice as Fast — The V8 team has made JSON.stringify over twice as fast, giving your apps an automatic performance boost for common tasks like API responses and caching, at least once Node upgrades to V8 13.8 (Node 24 uses V8 13.6). This article unpacks the low-level work behind the speedup.

Announcing TypeScript 5.9 — v5.9 is one of TypeScript’s gentler evolutionary steps, with no big features, but we do get support for import defer, a new --module node20 option, and ‘expandable hovers’ in editors like VS Code to see expanded type information. We also learn a little about TypeScript 6.0 which will act as a ‘transition point’ to get prepared for the Go-powered ‘native port’ of TypeScript which will become TypeScript 7.0.

IN BRIEF:
-
🔒 npm now lets you securely publish npm packages from CI/CD workflows using OpenID Connect (OIDC) for authentication.
-
NPKILL is a popular tool for digging into, and cleaning up, those heavy
node_modulesfolders you’ve accumulated. v1.0 is nearly here and its author is thinking about how it could be extended to cleaning up other types of clutter. -
npm creator Isaac Z. Schlueter is available for hire and his homepage implies he might no longer be working at vlt.
-
We featured Modern Node.js Patterns for 2025 over a month ago, but it seems to be blowing up all over social media right now, so is worth a look if you missed it at the time. It gives a good roundup of some of Node’s more recently added features.
Node.js v22.18 (LTS) Gets Type Stripping by Default — A big tweak for an LTS release: type stripping/TypeScript support is enabled by default, making node app.ts a reality, much as with Bun or Deno. It is, however, still considered ‘experimental.’

🛠 Code & Tools
pnpm 10.14: Adds Support for JavaScript Runtime Installation — The popular, efficiency-focused package installer now lets you define Node.js, Deno or Bun versions in package.json and pnpm will then download and pin them automatically.
