Fresh out the oven, still warm. Top of the tray.
Summary
Wasmer has open-sourced Edge.js, a JavaScript runtime designed to safely run Node.js applications in WebAssembly sandboxes for AI and edge computing. Unlike other edge runtimes like Deno or Cloudflare Workers, Edge.js maintains full Node.js compatibility while isolating unsafe execution parts using WebAssembly, enabling existing Node.js applications and native modules to run securely with improved density and startup times compared to containers.
Key quotes
· 5 pulledToday we are incredibly excited to open source Edge.js, a JavaScript runtime specifically designed to safely run Node.js workloads for AI and Edge computing.
The goal is simple: run your existing Node.js applications safely and with density and startup times that are impossible to get with containers.
Edge.js takes a different approach from existing JS edge runtimes like Deno or Cloudflare Workers.
Instead of introducing new APIs Edge.js preserves full Node compatibility and isolates the unsafe parts of execution using WebAssembly.
This allows existing Node.js applications and native modules to run securely with improved density and startup times compared to containers.
