TypeScript 6.0, Next.js 16.2, and a new Node.js runtime





















#​778 — March 24, 2026

Read on the Web




JavaScript Weekly








Announcing TypeScript 6.0 — Over six months in the making, TypeScript 6.0 is designed to bridge the gap between its self-hosted compiler and the (almost ready) Go-powered native compiler of TypeScript 7.0 . There are new features (Temporal improvements, RegExp.escape, and more), but most important are the changes to help you prepare for 7.0:




  • Numerous default changes: strict is now true, module is esnext, rootDir defaults to ., and more.

  • A change that will affect many apps is types defaulting to [] rather than pulling in everything from node_modules/@types.

  • Numerous deprecations: the es5 target, emitting AMD, UMD, and SystemJS modules, --baseUrl, and others.


  • --stableTypeOrdering makes 6.0's type ordering behavior match 7.0's to help diagnose inference differences as you update.

IN BRIEF:




  • 🤖 The Node.js community is wrestling with the role that LLM-produced code should play in its implementation, with the once creator of the io.js fork starting a petition to say 'no' to contributions built with AI assistance.




  • A large number of Deno employees announced (e.g.) they were departing the company last week. Deno employee Josh Collinsworth, not speaking for the company, noted "Deno is not going away. These are just hard times."




  • 📗 Chibivue is a code project and associated online book that provides, and explains how to build for yourself, a minimal Vue.js implementation.






RELEASES:




  • Next.js 16.2 – The React framework gets much faster next dev startup and ~50% faster rendering.




  • Storybook 10.3.0 – The component workshop adds Vite 8, Next.js 16.2, and ESLint 10 support, plus a preview of an MCP server for React dev.




  • ⚠️ All maintained Node.js versions are due security releases later today to address nine vulnerabilities.




  • Deno 2.7.6 – deno eval auto-detects CJS vs ESM, and --cpu-prof-flamegraph generates interactive SVG flamegraphs.




  • Bun 1.3.11, Valibot 1.3, ESLint 10.1

Solid v2.0.0 Beta: The <Suspense> is Over — After a long experimental phase, Solid 2.0’s first beta lands with first-class async support where computations can return Promises or async iterables, and the reactive graph suspends and resumes around them natively. <Suspense> is retired in favor of <Loading> for initial renders, and mutations get a first-class action() primitive with optimistic support. For existing users the breaking changes are substantial, but there’s a migration guide.
