react-native-transfer

A module for React Native for uploading multiple files

• Supports uploading multiple files at a time (currently downloading is not supported)
• Supports files and fields
• Supports the following file paths: file://path/to.file, data://path/to.file, /path/to.file and assets-library: (untested)
• Reports progress of file transfer percentage.

File uploading is built in to React Native

https://github.com/facebook/react-native/blob/master/Libraries/Network/FormData.js#L29

Polyfill for XMLHttpRequest2 FormData API, allowing multipart POST requests with mixed data (string, native files) to be submitted via XMLHttpRequest.

Example:

var photo = {
    uri: uriFromCameraRoll,
    type: 'image/jpeg',
    name: 'photo.jpg',
};

var body = new FormData();
body.append('authToken', 'secret');
body.append('photo', photo);
body.append('title', 'A beautiful photo!');

xhr.open('POST', serverURL);
xhr.send(body);

Road Map, Feature Requests & Bug Fixes

• To Do: Download file with progress

I will add to this module as I need more features and I hope you will too, pull requests are always welcome. I will not add features on request because I'm busy with other projects. I want this to be a community written module so if there is a feature that's missing or bug, add it or fix it and send me a pull request. If you don't know Objective C you can learn it. We all were where you are now at some point. StackOverflow.com is your friend. :)

Getting started

1. npm install react-native-transfer --save
2. In XCode, in the project navigator, right click your project ➜ Add Files to [your project's name]
3. Go to node_modules ➜ react-native-transfer and add Transfer.m & Transfer.h
4. Run your project (Cmd+R)

Testing

I suggest you go to requestb.in and create a unique link for testing. It's free, super easy to use and there is no sign up required. Do it!

Usage

'use strict';

var React = require('react-native');
var Transfer = require('react-native-transfer');

var {
  AppRegistry,
  StyleSheet,
  Text,
  View,
} = React;

var FileUploadDemo = React.createClass({
  componentDidMount: function() {
    var obj = {
        uploadUrl: 'http://requestb.in/XXXXXXX',  // Go to http://requestb.in/ and create your own link for testing
        method: 'POST', // default 'POST',support 'POST' and 'PUT'
        headers: {
          'Accept': 'application/json',
        },
        fields: {
            'hello': 'world',
        },
        files: [
          {
            name: 'one', // optional, if none then `filename` is used instead
            filename: 'one.w4a', // require, file name
            filepath: '/xxx/one.w4a', // require, file absolute path
            filetype: 'audio/x-m4a', // options, if none, will get mimetype from `filepath` extension
          },
        ]
    };

    // Add a listener to get progress
    var subscription = NativeAppEventEmitter.addListener(
        'transferring',
        (response) => {
            console.log("Transferring: percentage: ", response.progress * 100);
        }
    );
    Transfer.Upload(
        obj,
        function(response) {
            console.log('response: ', response);
            subscription.remove();
        },
        function(error) {
            console.log('error: ', error);
            subscription.remove();
        }
    );
  },
  render: function() {
    return (
      <View style={styles.container}>
        <Text style={styles.welcome}>
          Welcome to React Native!
        </Text>
      </View>
    );
  }
});

var styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: '#F5FCFF',
  },
  welcome: {
    fontSize: 20,
    textAlign: 'center',
    margin: 10,
  },
});

AppRegistry.registerComponent('FileUploadDemo', () => FileUploadDemo);
