    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.

    Heartbreaking: I’ve been using it intensively for a few hours now and I can’t find anything wrong with the viberewritten version. It’s smaller, faster, retains 100% feature parity and didn’t crash once, also no other unexpected behavior at any point.
