Deno 2.9

The scoop

Deno 2.9 introduces deno desktop, a new tool for building native desktop applications from web frameworks (Next.js, Astro, Fresh, etc.) without Electron, compiling to a single binary with native APIs built into the runtime. The release also makes migrating from Node projects easier with direct lockfile reading and adds CSS module imports, a stronger test runner, and Node.js 26 compatibility. Readers discuss persistent Node compatibility issues, edge cases blocking adoption, and concerns about stability compared to alternatives like Bun.
