This library requires Expo SDK 45 or newer

Installation

npx expo install expo-music-picker

Once the library is installed, create a new Development Build.

If you're installing this in a bare React Native app, you will need to have the expo package installed and configured.

Configuration in app.json / app.config.js

Add expo-music-picker to the plugins array of your app.json or app.config.js and then create a new Development Build to apply the changes.

{
  "expo": {
    "plugins": [
      "expo-music-picker",
      { "musicLibraryPermission": "The app accesses your music to play it" }
    ]
  }
}

The config plugin has the following options:

Name Type Explanation Required Default Value
musicLibraryPermission string 🍏 iOS only A string to set the NSAppleMusicUsageDescription permission message. "Allow $(PRODUCT_NAME) to access your music library"

Configuration for iOS 🍏

This is only required for usage in bare React Native apps.

Add NSAppleMusicUsageDescription key to your Info.plist:

<key>NSAppleMusicUsageDescription</key>
<string>Give $(PRODUCT_NAME) permission to access your music library</string>

Run npx pod-install after installing the npm package.

Configuration for Android 🤖

This is only required for usage in bare React Native apps.

This package automatically adds the READ_EXTERNAL_STORAGE permission. It is used when picking music from the phone's library.

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

Usage

import { useState } from "react";
import { Image, Text, View, Button } from "react-native";

import * as MusicPicker from "expo-music-picker";

export default function App() {
  const [item, setItem] = useState<MusicPicker.MusicItem | null>();

  const pickMediaAsync = async () => {
    try {
      // Request permissions
      const permissionResult = await MusicPicker.requestPermissionsAsync();
      if (!permissionResult.granted) {
        console.warn("No permission");
        return;
      }

      // Open the music picker
      const result = await MusicPicker.openMusicLibraryAsync({
        allowMultipleSelection: true,
        includeArtworkImage: true,
      });

      // Process the result
      console.log(result);
      if (!result.cancelled) {
        const [firstItem] = result.items;
        setItem(firstItem ?? null);
      }
    } catch (e) {
      console.warn("Exception occurred when picking music:", e);
    }
  };

  const artworkData = item?.artworkImage?.base64Data;

  return (
    <View style={{ flex: 1, alignItems: "center", justifyContent: "center" }}>
      <Button title="Open music library" onPress={pickMediaAsync} />
      <Text>
        {item ? `Song: ${item.artist} - ${item.title}` : "No song selected"}
      </Text>
      {artworkData && (
        <Image
          source={{ uri: `data:image/jpeg;base64,${artworkData}` }}
          style={{ width: 200, height: 200 }}
          resizeMode="contain"
        />
      )}
    </View>
  );
}

requestPermissionsAsync(): Promise<PermissionResponse>

Asks the user to grant permissions for accessing user's music library.

openMusicLibraryAsync(options?: MusicPickerOptions): Promise<PickerResult>
