React Native Zip Archive

Zip archive utility for react-native

Installation

npm install react-native-zip-archive --save
react-native link react-native-zip-archive

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)
})

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 })): 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.

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

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