{"library":"memory-fs","type":"library","category":null,"description":"memory-fs provides a simple, synchronous and asynchronous, in-memory filesystem abstraction, designed to hold data entirely within a JavaScript object. It mirrors a subset of the Node.js `fs` module API, making it suitable for scenarios where persistent disk I/O is undesirable or impractical, such as build tools, bundlers, and testing environments. The current stable version, 0.5.0, was released in 2017. While not actively developing new features, it is a critical, stable dependency for projects like Webpack, which relies on it for fast, transient asset compilation. Its primary differentiator is its complete in-memory operation and direct API compatibility with many standard `fs` methods, offering a performant alternative to disk-based operations for temporary file storage.","language":"javascript","status":"maintenance","version":"0.5.0","tags":["javascript","fs","memory"],"install":[{"cmd":"npm install memory-fs","imports":["const MemoryFileSystem = require('memory-fs');","const fs = new MemoryFileSystem();"]},{"cmd":"yarn add memory-fs","imports":[]},{"cmd":"pnpm add memory-fs","imports":[]}],"homepage":null,"github":"https://github.com/webpack/memory-fs","docs":null,"changelog":null,"pypi":null,"npm":"https://www.npmjs.com/package/memory-fs","openapi_spec":null,"status_page":null,"smithery":null,"compatibility":{"summary":{"python_range":"18–22","success_rate":0,"avg_install_s":null,"avg_import_s":null,"wheel_type":null},"url":"https://checklist.day/v1/registry/memory-fs/compatibility"},"provenance":{"verified_status":null,"verified_at":null,"last_verified":"Wed Jun 17","next_check":"Sat Jul 18","install_tag":null}}
