Deno 2.9
Deno 2.9 introduces new features including improved Node.js compatibility, better TypeScript support, and various performance enhancements to the JavaScript/TypeScript runtime.
Background
- Deno is a JavaScript/TypeScript runtime (like Node.js) created by Ryan Dahl, the original creator of Node.js. It was built from scratch to fix Node's architectural problems — particularly around security, module systems, and modern JavaScript support.
- Deno 2.9 introduces "Workspaces," a feature that lets developers manage multiple related projects (packages) in a single repository. This brings Deno closer to feature parity with Node's ecosystem tools (like npm workspaces and pnpm workspaces).
- The update also adds "vender" (offline caching of remote dependencies) and "compile" improvements. Previously, compiling Deno scripts to standalone executables had rough edges; this version smooths them out, making distribution easier.
- Deno remains a niche competitor to Node.js and Bun. Each release aims to reduce friction for developers migrating from Node, so these ergonomic improvements matter for adoption.
