Hooks

React v16.8 introduced hooks. If you are using a version of React Native that is before v0.59.0, your React Native version does not support hooks.

useTrackPlayerEvents

Register an event listener for one or more of the events emitted by the TrackPlayer. The subscription is removed when the component unmounts.

Check out the events section for a full list of supported events.

import React, { useState } from 'react';
import { Text, View } from 'react-native';
import { useTrackPlayerEvents, Event, State } from 'react-native-track-player';

// Subscribing to the following events inside MyComponent
const events = [
  Event.PlaybackState,
  Event.PlaybackError,
];

const MyComponent = () => {
  const [playerState, setPlayerState] = useState(null)

  useTrackPlayerEvents(events, (event) => {
    if (event.type === Event.PlaybackError) {
      console.warn('An error occured while playing the current track.');
    }
    if (event.type === Event.PlaybackState) {
      setPlayerState(event.state);
    }
  });

  const isPlaying = playerState === State.Playing;

  return (
    <View>
      <Text>The TrackPlayer is {isPlaying ? 'playing' : 'not playing'}</Text>
    </View>
  );
};

useProgress

State	Type	Description
position	number	The current position in seconds
buffered	number	The buffered position in seconds
duration	number	The duration in seconds

useProgress accepts an interval to set the rate (in miliseconds) to poll the track player's progress. The default value is 1000 or every second.

import React from 'react';
import { Text, View } from 'react-native';
import { useProgress } from 'react-native-track-player';

const MyComponent = () => {
  const { position, buffered, duration } = useProgress()

  return (
    <View>
      <Text>Track progress: {position} seconds out of {duration} total</Text>
      <Text>Buffered progress: {buffered} seconds buffered out of {duration} total</Text>
    </View>
  )
}

usePlaybackState

A hook which returns the up to date state of getPlaybackState(). The hook will initially return { state: undefined } while it is awaiting the initial state of the player.

import React, { useState } from 'react';
import { Text, View } from 'react-native';
import { usePlaybackState, State } from 'react-native-track-player';

const MyComponent = () => {
  const playerState = usePlaybackState();
  const isPlaying = playerState.state === State.Playing;

  return (
    <View>
      <Text>The TrackPlayer is {isPlaying ? 'playing' : 'not playing'}</Text>
    </View>
  );
};

usePlayWhenReady

A hook which returns the up to date state of TrackPlayer.getPlayWhenReady().

useActiveTrack

A hook which keeps track of the currently active track using TrackPlayer.getActiveTrack() and Event.PlaybackActiveTrackChanged.
