Manual installation

iOS

1. In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name]
2. Go to node_modules ➜ react-native-reat-native-get-music-files and add RNReatNativeGetMusicFiles.xcodeproj
3. In XCode, in the project navigator, select your project. Add libRNReatNativeGetMusicFiles.a to your project's Build Phases ➜ Link Binary With Libraries
4. Run your project (Cmd+R)<

Android

1. Open up android/app/src/main/java/[...]/MainApplication.java

• Add com.cinder92.musicfiles.RNReatNativeGetMusicFilesPackage; to the imports at the top of the file
• Add new RNReatNativeGetMusicFilesPackage() to the list returned by the getPackages() method

2. Append the following lines to android/settings.gradle:

   include ':react-native-get-music-files'
   project(':react-native-get-music-files').projectDir = new File(rootProject.projectDir, 	'../node_modules/react-native-get-music-files/android')
   

3. Insert the following lines inside the dependencies block in android/app/build.gradle:

     compile project(':react-native-get-music-files')
   

4. Add the following READ_EXTERNAL_STORAGE permission to AndroidManifest.xml

   <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

   Also starting from Android M, users need to be prompted for permission dynamically. Follow this link for more details on how to do that.

Usage

import MusicFiles from 'react-native-get-music-files';

MusicFiles.getAll({
    blured : true, // works only when 'cover' is set to true
    artist : true,
    duration : true, //default : true
    cover : false, //default : true,
    genre : true,
    title : true,
    cover : true,
    minimumSongDuration : 10000, // get songs bigger than 10000 miliseconds duration,
    fields : ['title','albumTitle','genre','lyrics','artwork','duration'] // for iOs Version
}).then(tracks => {
    // do your stuff...
}).catch(error => {
    // catch the error
})

//In order to get blocks of songs, for fix performance issues at least in Android, use next

componentWillMount() {
    DeviceEventEmitter.addListener(
        'onBatchReceived',
        (params) => {
            this.setState({songs : [
                ...this.state.songs,
                ...params.batch
            ]});
        }
    )
}

componentDidMount(){
        MusicFiles.getAll({
            id : true,
            blured : false,
            artist : true,
            duration : true, //default : true
            cover : true, //default : true,
            title : true,
            cover : true,
            batchNumber : 5, //get 5 songs per batch
            minimumSongDuration : 10000, //in miliseconds,
            fields : ['title','artwork','duration','artist','genre','lyrics','albumTitle']
        });
}

MusicFiles returns an array of objects where you can loop, something like this.

[
  {
    id : 1,
    title : "La danza del fuego",
    author : "Mago de Oz",
    album : "Finisterra",
    genre : "Folk",
    duration : 132132312321, // miliseconds
    cover : "file:///sdcard/0/123.png",
    blur : "file:///sdcard/0/123-blur.png", //Will come null if createBLur is set to false
    url : "/sdcard/0/la-danza-del-fuego.mp3"
  }
]

  • note :

    • If batchNumber is set, this method will not return any value and instead will fire the following events:

      Type	payload.batch	description
      onBatchReceived	array of songs	number of songs per batch is equal to batchNumber
      onLastBatchReceived	null	fires when the last batch has been sent

    • delay paramater determines how many ms should the native side wait before sending the next batch. This should help with UI thread performance on older devices.

    • event listeners should be used to catch these events ie:

         componentDidMount() {
           DeviceEventEmitter.addListener(
            'onBatchReceived',
            (p) => {
                this.setState({ ...this.state, tracks: [...this.state.tracks, p.batch] })
              }
            )
         }
