The server sample is based on this repository

# in project root
cd server
npm i
node ./server.js

It starts a server at localhost:3000 and accepts file upload through /upload POST request. Uploaded files will be stored in server/uploads folder.

This sample was created by initializing a blank React Native project

react-native init TestUploader

To run the demo:

# in project root
npm i
cd ios
pod install
cd ..
npm run ios

• First click on DOWNLOAD IMG and DOWNLOAD BIN to save an image and a binary file to app storage
• Then try clicking on UPLOAD IMG or UPLOAD BIN and observe the server console
• Notice how the image file has been changed when upload, but not the binary file
