A proposal argues that Node.js needs a built-in virtual file system (VFS) to solve critical issues with its current `fs` module, such as security vulnerabilities from path traversal attacks and the difficulty of mocking for testing. The VFS would provide a unified, secure, and mockable interface, representing a significant architectural improvement for the runtime.
Background
Node.js is a popular JavaScript runtime built on Chrome's V8 engine, commonly used for building server-side and networking applications. Its built-in `fs` module provides an API for interacting with the file system.
