    20170728-110148@2x android


    If your react-native version is under 0.57 please use version 2.x otherwise please use the latest version

    Getting started

    $ npm install @merryjs/photo-viewer --save


    $ yarn add @merryjs/photo-viewer

    Mostly automatic installation

    $ react-native link @merryjs/photo-viewer

    When you done this you still need link some frameworks into your xcode's embedded framework section, here you have some choices please see IOS link frameworks for more details

    and initialize Fresco Library please see Android Fresco initialize

    Manual installation


    1. In XCode, in the project navigator, right click LibrariesAdd Files to [your project's name]
    2. Go to node_modules@merryjs/photo-viewer and add MerryPhotoViewer.xcodeproj
    3. In XCode, in the project navigator, select your project. Add libMerryPhotoViewer.a to your project's Build PhasesLink Binary With Libraries
    4. Run your project (Cmd+R)<

    IOS Link Frameworks

    Manual link

    For some reasons if you dont want use any package manager in your side then you can link frameworks as:

    • Go to your xcode project choose your project if you unsure it click (command + 1)
    • Choose target General panel find embedded binaries click + icon will display a dialog and then go to node_modules/@merryjs/photo-viewer/ios/Carthage/Build/iOS/ folder add these frameworks into your xcode project. make sure checked copy items if needed and then It should looks like below, 20170728-110148@2x

    Add pod "NYTPhotoViewer", "~> 2.0.0" in your Podfile

    If you only use CocoaPods to define your react-native 3rd party libraries you can add this to you Podfile without linking to project as above:

    pod 'MerryPhotoViewer', path: '../node_modules/@merryjs/photo-viewer'

    If you want use Carthage in your project and then you can add these dependencies into your Cartfile

    github "NYTimes/NYTPhotoViewer"

    and run carthage update when you done this you can link it like Manual link from node_modules describes, the only difference is use your carthage file instead of ours


    1. Open up android/app/src/main/java/[...]/MainActivity.java
    • Add import com.merryjs.PhotoViewer.MerryPhotoViewPackage; to the imports at the top of the file
    • Add new MerryPhotoViewPackage() to the list returned by the getPackages() method
    1. Append the following lines to android/settings.gradle:

      include ':@merryjs/photo-viewer'
      project(':@merryjs/photo-viewer').projectDir = new File(rootProject.projectDir, 	'../node_modules/@merryjs/photo-viewer/android')
    2. Insert the following lines inside the dependencies block in android/app/build.gradle:

      compile project(':@merryjs/photo-viewer')
    3. Workaround for older gradles please see https://github.com/merryjs/photo-viewer/issues/39

      include ':merryjs-photo-viewer'
      project(':merryjs-photo-viewer').projectDir = new File(rootProject.projectDir,'../node_modules/@merryjs/photo-viewer/android')
      compile project(':merryjs-photo-viewer')

    Android targetSdkVersion configuration

    We use a third part library and both of them are target to targetSdkVersion 25, so you need update your build.gradle to the same version or you will meet a build error

    The configuration looks like: (android/app/build.gradle)

    android {
     compileSdkVersion 25
     buildToolsVersion "25.0.3"
     defaultConfig {
         applicationId "com.merryexamples"
         minSdkVersion 16
         targetSdkVersion 25
         versionCode 1
         versionName "1.0"
         ndk {
             abiFilters "armeabi-v7a", "x86"
         renderscriptTargetApi 25
         renderscriptSupportModeEnabled true
    	// ...

    If we have any better solution will update this section in the future.

    Android Fresco initialize

    When you have linked you need one more step for initialize the Fresco Library in MainApplication.java

    import com.facebook.drawee.backends.pipeline.Fresco; // <-- import on top of the file
    // ...
    public void onCreate() {
    	SoLoader.init(this, /* native exopackage */ false);

    If your pictures are very large, you can initialize with these configurations in MainApplication.java

    // Add these imports on top of the file
    import com.facebook.drawee.backends.pipeline.Fresco;
    import com.facebook.imagepipeline.core.ImagePipelineConfig;
    import com.facebook.imagepipeline.decoder.SimpleProgressiveJpegConfig;
    // ...
    public void onCreate() {
    	SoLoader.init(this, /* native exopackage */ false);
      ImagePipelineConfig config = ImagePipelineConfig.newBuilder(this)
        .setProgressiveJpegConfig(new SimpleProgressiveJpegConfig())
      Fresco.initialize(this, config);

    Thats all.


    The most part from this package is setup the Native side dependencies, once you have done it before, you can use it as below, very very easy to use:

    import PhotoView from "@merryjs/photo-viewer";
    // local image
    const cat = require("./cat-2575694_1920.jpg");
    const photos = [
        source: {
        title: "Flash End-of-Life",
          "Adobe announced its roadmap to stop supporting Flash at the end of 2020. ",
        // must be valid hex color or android will crashes
        titleColor: "#f90000",
        summaryColor: "green"
        source: cat,
        title: "Local image"
        source: {
        source: {
        source: {
        source: {
          uri: "https://media.giphy.com/media/3o6vXWzHtGfMR3XoXu/giphy.gif"
        title: "gif 1"
      onDismiss={e => {
        // don't forgot set state back.
        this.setState({ visible: false });
