REACT BENCH TOOLING GETS JSON OUTPUT, EYES NEXT.JS INTEGRATION

By RepoJournal · Filed · About Meta

1 person shipped this

React's benchmark suite now exports machine-readable JSON, unblocking its adoption in Next.js performance tracking.

Dan Abramov landed a bench infrastructure upgrade [1] that adds JSON output capability and declares missing dependencies, work discovered while wiring React's benchmarks into the Next.js test pipeline [2]. The change is minimal but purposeful: React's performance telemetry can now feed directly into downstream build tools instead of requiring manual parsing. This matters because Next.js has been waiting on exactly this capability [2] to automate performance regression detection across releases. The bench improvements ship lean, 1 commit across the frame, solving a real integration blocker without scope creep.
