react-native-background-upload

The only React Native http post file uploader with android and iOS background support. If you are uploading large files like videos, use this so your users can background your app during a long upload.

NOTE: Use major version 4 with RN 47.0 and greater. If you have RN less than 47, use 3.0. To view all available versions: npm show react-native-background-upload versions

Installation

1. Install package

npm install --save react-native-background-upload

or

yarn add react-native-background-upload

Note: if you are installing on React Native < 0.47, use react-native-background-upload@3.0.0 instead of react-native-background-upload

2. Link Native Code

Autolinking (React Native >= 0.60)

iOS

cd ./ios && pod install && cd ../

Android

No further actions required.

Automatic Native Library Linking (React Native < 0.60)

react-native link react-native-background-upload

Or, Manually Link It

iOS

1. In the XCode's "Project navigator", right click on your project's Libraries folder ➜ Add Files to <...>
2. Go to node_modules ➜ react-native-background-upload ➜ ios ➜ select VydiaRNFileUploader.xcodeproj
3. Add VydiaRNFileUploader.a to Build Phases -> Link Binary With Libraries

Android

1. Add the following lines to android/settings.gradle:

   include ':react-native-background-upload'
   project(':react-native-background-upload').projectDir = new File(settingsDir, '../node_modules/react-native-background-upload/android')

2. Add the compile and resolutionStrategy line to the dependencies in android/app/build.gradle:

   configurations.all { resolutionStrategy.force 'com.squareup.okhttp3:okhttp:3.4.1' } // required by react-native-background-upload until React Native supports okhttp >= okhttp 3.5
   
   dependencies {
       compile project(':react-native-background-upload')
   }

3. Add the import and link the package in MainApplication.java:

   import com.vydia.RNUploader.UploaderReactPackage;  <-- add this import
   
   public class MainApplication extends Application implements ReactApplication {
       @Override
       protected List<ReactPackage> getPackages() {
           return Arrays.<ReactPackage>asList(
               new MainReactPackage(),
               new UploaderReactPackage() // <-- add this line
           );
       }
   }

4. Ensure Android SDK versions. Open your app's android/app/build.gradle file. Ensure compileSdkVersion and targetSdkVersion are 25. Otherwise you'll get compilation errors.

3. Expo

To use this library with Expo one must first detach (eject) the project and follow step 2 instructions. Additionally on iOS there is a must to add a Header Search Path to other dependencies which are managed using Pods. To do so one has to add $(SRCROOT)/../../../ios/Pods/Headers/Public to Header Search Path in VydiaRNFileUploader module using XCode.

Usage

import Upload from 'react-native-background-upload'

const options = {
  url: 'https://myservice.com/path/to/post',
  path: 'file://path/to/file/on/device',
  method: 'POST',
  type: 'raw',
  maxRetries: 2, // set retry count (Android only). Default 2
  headers: {
    'content-type': 'application/octet-stream', // Customize content-type
    'my-custom-header': 's3headervalueorwhateveryouneed'
  },
  // Below are options only supported on Android
  notification: {
    enabled: true
  },
  useUtf8Charset: true
}

Upload.startUpload(options).then((uploadId) => {
  console.log('Upload started')
  Upload.addListener('progress', uploadId, (data) => {
    console.log(`Progress: ${data.progress}%`)
  })
  Upload.addListener('error', uploadId, (data) => {
    console.log(`Error: ${data.error}%`)
  })
  Upload.addListener('cancelled', uploadId, (data) => {
    console.log(`Cancelled!`)
  })
  Upload.addListener('completed', uploadId, (data) => {
    // data includes responseCode: number and responseBody: Object
    console.log('Completed!')
  })
}).catch((err) => {
  console.log('Upload error!', err)
})

Multipart Uploads

Just set the type option to multipart and set the field option. Example:

const options = {
  url: 'https://myservice.com/path/to/post',
  path: 'file://path/to/file%20on%20device.png',
  method: 'POST',
  field: 'uploaded_media',
  type: 'multipart'
}

Note the field property is required for multipart uploads.

API

Top Level Functions

All top-level methods are available as named exports or methods on the default export.

startUpload(options)

The primary method you will use, this starts the upload process.

Returns a promise with the string ID of the upload. Will reject if there is a connection problem, the file doesn't exist, or there is some other problem.

options is an object with following values:

Note: You must provide valid URIs. react-native-background-upload does not escape the values you provide.

Customizing Android Build Properties

You may want to customize the compileSdk, buildToolsVersion, and targetSdkVersion versions used by this package. For that, add this to android/build.gradle:

ext {
    targetSdkVersion = 23
    compileSdkVersion = 23
    buildToolsVersion = '23.0.2'
}

Add it above allProjects and you're good. Your android/build.gradle might then resemble:

buildscript {
    repositories {
        jcenter()
    }
}

ext {
    targetSdkVersion = 27
    compileSdkVersion = 27
    buildToolsVersion = '23.0.2'
}

FAQs

Is there an example/sandbox app to test out this package?

Yes, there is a simple react native app that comes with an express server where you can see react-native-background-upload in action and try things out in an isolated local environment.

RNBackgroundExample

Does it support iOS camera roll assets?

Yes, as of version 4.3.0.

Does it support multiple file uploads?

Yes and No. It supports multiple concurrent uploads, but only a single upload per request. That should be fine for 90%+ of cases.

Why should I use this file uploader instead of others that I've Googled like react-native-uploader?

This package has two killer features not found anywhere else (as of 12/16/2016). First, it works on both iOS and Android. Others are iOS only. Second, it supports background uploading. This means that users can background your app and the upload will continue. This does not happen with other uploaders.

Common Issues

BREAKING CHANGE IN 3.0

This is for 3.0 only. This does NOT apply to 4.0, as recent React Native versions have upgraded the okhttp dependencies. Anyway...

In 3.0, you need to add

    configurations.all { resolutionStrategy.force 'com.squareup.okhttp3:okhttp:3.4.1' }

to your app's app's android/app/build.gradle file.

Just add it above (not within) dependencies and you'll be fine.

BREAKING CHANGE IN 2.0

Two big things happened in version 2.0. First, thehe Android package name had to be changed, as it conflicted with our own internal app. My bad. Second, we updated the android upload service dependency to the latest, but that requires the app have a compileSdkVersion and targetSdkVersion or 25.

To upgrade: In MainApplication.java:

Change

```java
import com.vydia.UploaderReactPackage;
```

to

```java
import com.vydia.RNUploader.UploaderReactPackage;
```

Then open your app's android/app/build.gradle file. Ensure compileSdkVersion and targetSdkVersion are 25.

Done!

Thanks to:

• android-upload-service It made Android dead simple to support.

• MIME type from path on iOS Thanks for the answer!
