Summary
Wasmer engineers used Codex (an AI code generation tool) to build Edge.js, a JavaScript runtime that runs Node.js workloads inside WebAssembly (a low-level code format that runs in sandboxes for security and portability). What would have taken one year to build was completed in two weeks, allowing a small team to tackle a project previously only feasible at large companies.
