rn-fetch-blob

A React Native module for file transfer (download/upload) and file system access, supporting large file streaming with ArrayBuffer and Blob. Version 0.12.0 is the latest stable release; development is sporadic with few recent updates. Differentiators include streaming for large files and direct file system access, though it is superseded by react-native-blob-util (actively maintained fork) and react-native-fs for simpler needs.
