Deno desktop ships; startup 2x faster, memory 3x less
Deno 2.9 introduces deno desktop, a new command that builds native desktop applications from web framework projects with no extra toolchain, producing a single distributable binary with built-in Deno.* desktop APIs. Performance gains include 2x faster cold startup (17ms), up to 3x less RSS memory, and 27% higher realworld Deno.serve throughput. Also adds direct npm, pnpm, yarn, and Bun lockfile reading in deno install, CSS module imports, and a stronger test runner.
