Exploring Next — Ep 426 w/ Justy & Cody — Virtual File System for Node.js by mcollina · Pull Request #61478 · nodejs/node
Matteo Collina's virtual file system PR for Node.js introduces a first-class node:vfs module with a provider-based architecture that lets you mount in-memory, Single Executable Application, or custom filesystems alongside the real filesystem. It intercepts 164+ fs and module-loader integration points to make require() and standard fs APIs work seamlessly with virtual files, includes overlay mode for surgical mocking, and integrates with the test runner.
