@yarnpkg/fslib
Advanced tools
@yarnpkg/fslibA TypeScript library abstracting the Node filesystem APIs. We use it for three main reasons:
Our library has two path types, NativePath and PortablePath. Most interfaces only accept the later, and instances of the former need to be transformed back and forth using our type-safe utilities before being usable.
The FSLib implements various transparent filesystem layers for a variety of purposes. For instance we use it in Yarn in order to abstract away the zip archive manipulation logic, which is implemented in ZipFS and exposed through a Node-like interface (called FakeFS).
All FakeFS implementations can be transparently layered on top of the builtin Node fs module, and that's for instance how we can add support for in-zip package loading without you having to care about the exact package format.
All methods from the FakeFS interface are promisified by default (and suffixed for greater clarity, for instance we offer both readFileSync and readFilePromise).
fs-extra is a popular library that extends the native Node.js fs module with additional methods and promises. It provides similar functionalities to @yarnpkg/fslib, such as file and directory operations, but it is more general-purpose and not specifically tied to the Yarn ecosystem.
node-fs is another library that extends the native fs module with additional features like recursive directory creation and symbolic link support. It offers similar capabilities to @yarnpkg/fslib but is less focused on path manipulation and more on enhancing the core fs module.
graceful-fs is a drop-in replacement for the native fs module that improves its reliability, especially under heavy load. While it doesn't offer as many high-level utilities as @yarnpkg/fslib, it ensures more robust file system operations.
