Download Files
Downloading files, such as PDFs, images, or documents, is a common requirement for apps that let users save content locally on their device. This tutorial explains how to implement file downloads in React Native.
Using react-native-fs
The react-native-fs library provides file system access for downloading and saving files directly to the device.
Downloading a File
Tracking Download Progress
Saving Images to the Gallery
For image files specifically, the CameraRoll module or libraries like react-native-cameraroll allow saving downloaded images directly to the device’s photo gallery.
Requesting Storage Permissions
On Android, saving files to certain directories requires explicit storage permissions, which must be requested before attempting the download.
Opening Downloaded Files
Once downloaded, files can be opened using libraries like react-native-file-viewer, allowing users to view PDFs or documents directly within the app.
Conclusion
Implementing file downloads with progress tracking and proper permission handling allows React Native applications to offer offline access to important documents, reports, and media content.
