matrixai/js-virtualfs

VirtualFS is an in-memory, POSIX-like filesystem for JavaScript that runs in both Node.js and browsers, providing features like symlinks, hardlinks, virtual inodes, and device file support. It's designed for developers who need a complete, Node-compatible filesystem API in environments where persistent storage isn't available or desired, such as browser-based applications or sandboxed Node.js environments. The project is particularly useful for testing, sandboxed execution, and applications that require filesystem operations without actual disk I/O.
