Next.js 11 is released

Highlights include:

  • Next.js Live -- A new, open-source development environment that enables real-time, collaborative coding in the browser. It uses Wasm, ESM, Service Workers, and a bunch of other stuff to generate a live URL (without a build step) that you can share with anyone -- so your whole team can edit, chat, draw, and see updates happen in real time.

  • Conformance -- Google's new system of "strong defaults and actionable rules" for improving performance out of the box with frameworks like Next.js.

  • Better, faster dev experience -- Startup time improved by 24%, processing time for changes was reduced by 40%, and the next/image component got some big improvements.
