Zip archive utility for react-native

## Installation

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

## Usage

import it into your code

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

you may also want to use something like [react-native-fs](https://github.com/johanneslumpe/react-native-fs) to access the file system (check its repo for more information)

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

## API

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

> zip source to target

Example

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

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

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

> unzip from source to target

Example

```js
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.

```js
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 unzip progress callbacks. Useful for displaying a progress bar on your UI during the unzip 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.

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

```js
componentWillMount() {
  this.zipProgress = subscribe((e) => {
    this.setState({ zipProgress: e.progress })
  })
}

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