Edge.js: Running Node apps inside a WebAssembly Sandbox
Summary
Wasmer announces Edge.js, an open-source JavaScript runtime designed to safely run Node.js workloads inside a WebAssembly sandbox. It preserves full Node compatibility while isolating unsafe OS calls and native modules via WASIX, enabling dense, serverless edge deployments without Docker. The post covers architecture, design decisions, compatibility with Node.js v24, testing, performance considerations, and the role of AI tooling in the development process.
