useMidiPlayer : React Hook and Context to play midi files

Before all, all credits goes to @ryohey for his [wavelet](https://github.com/ryohey/wavelet library that I used to create this hook. You should check his work on Signal, it's really cool.

This hook allow you to play midi files in your react app. It use the midifile-ts library to parse the midi file and wavelet to play it.

npm install @maximethizeau/use-midi-player

# or

yarn add @maximethizeau/use-midi-player

Usage

You can use one of the following methods to play a midi file:

• useSingleMidiPlayer hook

const LoadByHook: React.FC<Props> = () => {
  const { synth } = useMidiPlayer({
    url: 'Numb.mid',
  })
  return (
    <>
      <button id="button-play" onClick={synth?.play}>
        Play
      </button>
      <button id="button-pause" onClick={synth?.pause}>
        Pause
      </button>
      <button id="button-pause" onClick={synth?.stop}>
        Stop
      </button>
    </>
  )
}

• useMidiPlayerContext hook

const LoadByContext: React.FC<Props> = () => {
  const { synth } = useMidiPlayerContext()

  useEffect(() => {
    if (!synth) return
    synth?.load('Numb.mid')
  }, [synth])

  return (
    <>
      <button id="button-play" onClick={synth?.play}>
        Play
      </button>
      <button id="button-pause" onClick={synth?.pause}>
        Pause
      </button>
      <button id="button-pause" onClick={synth?.stop}>
        Stop
      </button>
    </>
  )
}

const App: React.FC<Props> = () => {
  return (
    <MidiPlayerProvider>
      <LoadByContext />
    </MidiPlayerProvider>
  )
}

• MidiPlayerExample component

const App: React.FC<Props> = () => {
  // Simple component that allow you to upload a midi file and play it
  return <MidiPlayerExample url="Numb.mid" />
