• Edit android/settings.gradle to look like this (without the +):

  rootProject.name = 'MyApp'
  
  include ':app'
  
  + include ':react-native-zip-archive'
  + project(':react-native-zip-archive').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-zip-archive/android')

• Edit android/app/build.gradle (note: app folder) to look like this:

  apply plugin: 'com.android.application'
  
  android {
    ...
  }
  
  dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:23.0.0'
    compile 'com.facebook.react:react-native:0.16.+'
  + compile project(':react-native-zip-archive')
  }

• For react-native blew 0.19.0

  • Edit your MainActivity.java (deep in android/app/src/main/java/...) to look like this (note two places to edit):

  + import import com.rnziparchive.RNZipArchivePackage;
  
  ....
  
    @Override
    protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      mReactRootView = new ReactRootView(this);
  
      mReactInstanceManager = ReactInstanceManager.builder()
        .setApplication(getApplication())
        .setBundleAssetName("index.android.bundle")
        .setJSMainModuleName("index.android")
        .addPackage(new MainReactPackage())
  +     .addPackage(new RNZipArchivePackage())
        .setUseDeveloperSupport(BuildConfig.DEBUG)
        .setInitialLifecycleState(LifecycleState.RESUMED)
        .build();
  
      mReactRootView.startReactApplication(mReactInstanceManager, "ExampleRN", null);
  
      setContentView(mReactRootView);
    }

• react-native 0.19.0 and higher

  • Edit your MainActivity.java (deep in android/app/src/main/java/...) to look like this (note two places to edit):

  package com.myapp;
  
  + import com.rnziparchive.RNZipArchivePackage;
  
  ....
  
    @Override
    protected List<ReactPackage> getPackages() {
      return Arrays.<ReactPackage>asList(
        new MainReactPackage(),
  +     new RNZipArchivePackage()
      );
    }
  
  }

• For react-native 0.29.0 and higher ( in MainApplication.java )

  • Edit your MainApplication.java (deep in android/app/src/main/java/...) to look like this (note three places to edit):

  + import com.rnziparchive.RNZipArchivePackage;
  
  public class MainApplication extends Application implements ReactApplication {
    ...
      @Override
      protected List<ReactPackage> getPackages() {
        return Arrays.<ReactPackage>asList(
  -       new MainReactPackage()
  +       new MainReactPackage(),
  +       new RNZipArchivePackage()
        );
      }

Usage

import it into your code

import { zip, unzip, unzipAssets, subscribe } from 'react-native-zip-archive'

you may also want to use something like react-native-fs to access the file system (check its repo for more information)

import { MainBundlePath, DocumentDirectoryPath } from 'react-native-fs'

API

zip(source: string, target: string): Promise

zip source to target

Example

const targetPath = `${DocumentDirectoryPath}/myFile.zip`
const sourcePath = DocumentDirectoryPath

zip(sourcePath, targetPath)
.then((path) => {
  console.log(`zip completed at ${path}`)
})
.catch((error) => {
  console.log(error)
})

unzip(source: string, target: string): Promise

unzip from source to target

Example

const sourcePath = `${DocumentDirectoryPath}/myFile.zip`
const targetPath = DocumentDirectoryPath

unzip(sourcePath, targetPath)
.then((path) => {
  console.log(`unzip completed at ${path}`)
})
.catch((error) => {
  console.log(error)
})

unzipWithPassword(source: string, target: string, passowrd: string): Promise

unzip from source to target

Example

const sourcePath = `${DocumentDirectoryPath}/myFile.zip`
const targetPath = DocumentDirectoryPath
const password = 'password'

unzipWithPassword(sourcePath, targetPath, password)
.then((path) => {
  console.log(`unzip completed at ${path}`)
})
.catch((error) => {
  console.log(error)
})

unzipAssets(assetPath: string, target: string): Promise

unzip file from Android assets folder to target path

Note: Android only.

assetPath is the relative path to the file inside the pre-bundled assets folder, e.g. folder/myFile.zip. Do not pass an absolute directory.

const assetPath = `${DocumentDirectoryPath}/myFile.zip`
const targetPath = DocumentDirectoryPath

unzipAssets(assetPath, targetPath)
.then(() => {
  console.log('unzip completed!')
})
.catch((error) => {
  console.log(error)
})

subscribe(callback: ({ progress: number, filePath: string })): EmitterSubscription

Subscribe to the progress callbacks. Useful for displaying a progress bar on your UI during the process.

Your callback will be passed an object with the following fields:

• progress (number) a value from 0 to 1 representing the progress of the unzip method. 1 is completed.
• filePath (string) the zip file path of zipped or unzipped file.

Note: Remember to check the filename while processing progress, to be sure that the unzipped or zipped file is the right one, because the event is global.

Note: Remember to unsubscribe! Run .remove() on the object returned by this method.

componentDidMount() {
  this.zipProgress = subscribe(({ progress, filePath }) => {
    this.setState({ zipProgress: progress })
  })
}

componentWillUnmount() {
  // Important: Unsubscribe from the progress events
  this.zipProgress.remove()
}
