Matteo Collina, Node.js TSC member and Platformatic co-founder, has proposed a built-in Virtual File System (VFS) for Node.js core via a new node:vfs module (PR #61478). The proposal covers ~19,000 lines of code across 100 files and targets use cases like in-memory test execution, AI-generated code sandboxing, Single Executable Applications, and multi-tenant file access isolation. A userland package (@platformatic/vfs) is already available on npm for Node.js 22+, with Vercel and LangChain having independently adopted similar APIs. The PR has sparked significant debate because Collina used Claude Code to build much of the implementation. Long-time contributor Fedor Indutny launched a GitHub petition to ban AI-generated code from Node.js core, citing concerns about Developer Certificate of Origin compliance and reviewer ability to verify machine-generated code. The Node.js TSC is expected to vote on policies governing AI-assisted contributions.
