## What it is
A React Native library providing file access, upload/download, and streaming APIs with native-to-native file handling to avoid BASE64 bridging overhead. It also offers Blob, File, and XMLHttpRequest polyfills for browser-based libraries in React Native.

## Use cases
- download files in react native with progress
- upload multipart form data with files from react native
- read and write large files with streams in react native
- access camera roll and asset files in react native
- use browser libraries that need Blob or XMLHttpRequest in react native
- manage cached files on android and ios

## When to choose
- maintaining a legacy React Native app already using react-native-fetch-blob
- you need file streaming and direct storage transfer in an old RN project

## When to avoid
- starting a new React Native project - the repo has moved to joltup/rn-fetch-blob and this version is unmaintained
- you need long-term support or recent React Native compatibility

## Facets
