    In the next version of Bun `process` emits a "memoryPressure" event when the system runs low on memory (thanks @codebytere!)
    Bun · react to system memory pressure
// level: "warning" | "critical"
process.on("memoryPressure", (level) => {
  if (level === "critical") cache.clear();
});

    In the next version of Bun `bun build --react-compiler` runs the React Compiler in Rust On a large React codebase, it's 19x faster than the Babel plugin
    Wall time
vs Babel plugin
Baseline ( reactCompiler: false )
391 ms
-
reactCompiler: true
484 ms
19.8x faster
Babel plugin (same input)

    enough with the tyranny of V8 isolates, everyone now gets a real x86_64 VM but without cold starts and with serverless DX, ergonomics and economics (except cheaper than the competition) blog posts incoming!

    Hot take after 2 years of Bun in production: the DX is good enough that I'd pick it over Node even for "boring" enterprise work. @bunjavascript + @elysiaJS + @DrizzleORM is the most fun I've had shipping backend in years.
