Cross platform photo upload component for react native

react-native-photo-upload

This component handles all the hassle in dealing with photos in react native, it's built on top of react-native-image-picker, react-native-image-resizer and react-native-fs it takes an image component and upon click, you get the image picker prompt, get the base64 string of the image and the image source changes to whatever image was picked.

react-native link react-native-fs

The following steps are required by react-native-image-picker for both Android and IOS even with automatic linking

Android

  • Update the android build tools version to 2.2.+ in android/build.gradle (required step by `react-native-image-picker):
buildscript {
    ...
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.+' // <- USE 2.2.+ version
    }
    ...
}
...
  • Update the gradle version to 2.14.1 in android/gradle/wrapper/gradle-wrapper.properties:
 ...
 distributionUrl=https\://services.gradle.org/distributions/gradle-2.14.1-all.zip
  • Add the required permissions in AndroidManifest.xml:
 <uses-permission android:name="android.permission.CAMERA" />
 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

IOS

For iOS 10+, Add the NSPhotoLibraryUsageDescription, NSCameraUsageDescription, and NSMicrophoneUsageDescription (if allowing video) keys to your Info.plist with strings describing why your app needs these permissions. Note: You will get a SIGABRT crash if you don't complete this step

<plist version="1.0">
  <dict>
    ...
    <key>NSPhotoLibraryUsageDescription</key>
    <string>YOUR_REASON_FOR_USING_USER_PHOTOS_HERE</string>
    <key>NSCameraUsageDescription</key>
    <string>YOUR_REASON_FOR_USING_USER_CAMERA_HERE</string>
  </dict>
</plist>
