React Native Fetch Blob

Overview:

The react-native-fetch-blob is a project created to address issues related to React Native's lack of Blob implementation, aimed at making file access and data transfer more efficient for React Native developers. It includes features like direct data transfer to storage without BASE64 bridging, different file API support, and native-to-native file manipulation API.

Features:

• Direct Data Transfer: Transfer data directly from/to storage without BASE64 bridging.
• File API support: Supports regular files, Asset files, and CameraRoll files.
• Native-to-Native File Manipulation API: Reduces JS bridging performance loss.
• File Stream Support: Supports dealing with large files without OOM problems.
• Polyfills: Includes Blob, File, XMLHttpRequest polyfills for browser-based library availability.
• JSON Stream Support: Supported based on Oboe.js for seamless JSON streaming.
• Web API Polyfills: Experimental feature allowing the use of browser-based libraries in React Native.

Summary:

The react-native-fetch-blob project offers a comprehensive solution for file access and data transfer in React Native applications, addressing issues related to Blob implementation. With features like direct data transfer, file API support, and native-to-native file manipulation, developers can enhance efficiency in handling file operations. The availability of experimental features like Web API polyfills further extends the capabilities by enabling the use of browser-based libraries within React Native environments.
