## Installation
```sh
npm install --save discord-music
```
Install **opusscript** or **node-opus**:
```sh
npm install --save opusscript
```
Install [FFMPEG](https://www.ffmpeg.org/download.html) and you're done!
## Player
```js
const Discord = require("discord.js"),
client = new Discord.Client(),
settings = {
prefix: "!",
token: "Your Discord Token"
};
const { Player } = require('discord-music');
const player = new Player(client, "YOUTUBE API KEY", {
leaveOnEnd: true,
leaveOnStop: true
});
// To easily access the player
client.player = player;
client.on("ready", () => {
console.log("I'm ready !");
});
client.login(settings.token);
```
### Play
To play a song, use the `client.manager.play()` function.
**Usage:**
```js
client.player.play(voiceChannel, songName);
```
**Example**:
```js
client.on('message', async (message) => {
const args = message.content.slice(settings.prefix.length).trim().split(/ +/g);
const command = args.shift().toLowerCase();
// !play Despacito
// will play "Despacito" in the member voice channel
if(command === 'play'){
let song = await client.player.play(message.member.voice.channel, args[0])
message.channel.send(`Currently playing ${song.name}!`);
}
```
### Pause
To pause the current song, use the `client.manager.pause()` function.
**Usage:**
```js
client.player.pause(guildID);
```
**Example**:
```js
client.on('message', async (message) => {
const args = message.content.slice(settings.prefix.length).trim().split(/ +/g);
const command = args.shift().toLowerCase();
if(command === 'pause'){
let song = await client.player.pause(message.guild.id);
message.channel.send(`${song.name} paused!`);
}
});
```
### Resume
To resume the current song, use the `client.manager.resume()` function.
**Usage:**
```js
client.player.resume(guildID);
```
**Example**:
```js
client.on('message', async (message) => {
const args = message.content.slice(settings.prefix.length).trim().split(/ +/g);
const command = args.shift().toLowerCase();
if(command === 'resume'){
let song = await client.player.resume(message.guild.id);
message.channel.send(`${song.name} resumed!`);
}
});
```
### Stop
To stop the music, use the `client.manager.stop()` function.
**Usage:**
```js
client.player.stop(guildID);
```
**Example**:
```js
client.on('message', (message) => {
const args = message.content.slice(settings.prefix.length).trim().split(/ +/g);
const command = args.shift().toLowerCase();
if(command === 'stop'){
client.player.stop(message.guild.id);
message.channel.send('Music stopped!');
}
});
```
### SetVolume
To update the volume, use the `client.manager.setVolume()` function.
**Usage:**
```js
client.player.setVolume(guildID, percent);
```
**Example**:
```js
client.on('message', (message) => {
const args = message.content.slice(settings.prefix.length).trim().split(/ +/g);
const command = args.shift().toLowerCase();
if(command === 'setvolume'){
client.player.setVolume(message.guild.id, parseInt(args[0]));
message.channel.send(`Volume set to ${args[0]} !`);
}
});
```
### AddToQueue
To add a song to the queue, use the `client.player.addToQueue()` function.
**Usage:**
```js
client.player.addToQueue(guildID, songName);
```
**Example:**
In this example, you will see how to add a song to the queue if one is already playing.
```js
client.on('message', async (message) => {
const args = message.content.slice(settings.prefix.length).trim().split(/ +/g);
const command = args.shift().toLowerCase();
if(command === 'play'){
let aSongIsAlreadyPlaying = client.player.isPlaying(message.guild.id);
// If there's already a song playing
if(aSongIsAlreadyPlaying){
// Add the song to the queue
let song = await client.player.addToQueue(message.guild.id, args[0]);
message.channel.send(`${song.name} added to queue!`);
} else {
// Else, play the song
let song = await client.player.play(message.member.voice.channel, args[0]);
message.channel.send(`Currently playing ${song.name}!`);
}
}
});
```
### ClearQueue
To clear the queue, use the `client.player.clearQueue()` function.
**Usage:**
```js
client.player.clearQueue(guildID);
```
**Example:**
```js
client.on('message', (message) => {
const args = message.content.slice(settings.prefix.length).trim().split(/ +/g);
const command = args.shift().toLowerCase();
if(command === 'clear-queue'){
client.player.clearQueue(message.guild.id);
message.channel.send('Queue cleared!');
}
});
```
### GetQueue
To get the server queue, use the `client.player.getQueue()` function.
**Usage:**
```js
client.player.getQueue(guildID);
```
**Example:**
```js
client.on('message', (message) => {
const args = message.content.slice(settings.prefix.length).trim().split(/ +/g);
const command = args.shift().toLowerCase();
if(command === 'queue'){
let queue = await client.player.getQueue(message.guild.id);
message.channel.send('Server queue:\n'+(queue.songs.map((song, i) => {
return `${i === 0 ? 'Current' : `#${i+1}`} - ${song.name} | ${song.author}`
}).join('\n')));
}
/**
* Output:
*
* Server queue:
* Current - Despacito | Luis Fonsi
* #2 - Memories | Maroon 5
* #3 - Dance Monkey | Tones And I
* #4 - Circles | Post Malone
*/
});
```
## Info Messages
You can send a message when the queue ends or when the song changes:
```js
client.on('message', (message) => {
const args = message.content.slice(settings.prefix.length).trim().split(/ +/g);
const command = args.shift().toLowerCase();
if(command === 'play'){
let song = await client.player.play(message.member.voice.channel, args[0]);
song.queue.on('end', () => {
message.channel.send('The queue is empty, please add new songs!');
});
song.queue.on('songChanged', (oldSong, newSong) => {
message.channel.send(`Now playing ${newSong}...`);
});
}
```
## Handle errors
There are 2 main errors that you can handle like this:
```js
client.on('message', (message) => {
const args = message.content.slice(settings.prefix.length).trim().split(/ +/g);
const command = args.shift().toLowerCase();
// Error 1:
// Song not found
if(command === 'play'){
client.player.play(message.member.voice.channel, args[0]).then((song) => {
message.channel.send(`Currently playing ${song.name}!`);
}).catch(() => {
message.channel.send(`No song found for ${args[0]}`);
});
}
// Error 2:
// Not playing
if(command === 'queue'){
let playing = client.player.isPlaying(message.guild.id);
if(!playing) return message.channel.send(':x: No songs currently playing!');
// you are sure it works:
client.player.getQueue(message.guild.id);
}
});
```

};
const { Player } = require('discord-music');
const player = new Player(client, &quot;YOUTUBE API KEY&quot;, {
leaveOnEnd: true,

<p><strong>Example</strong>:</p>
<pre class="prettyprint source lang-js"><code>client.on('message', async (message) => {
const args = message.content.slice(settings.prefix.length).trim().split(/ +/g);
const command = args.shift().toLowerCase();
// !play Despacito
// will play &quot;Despacito&quot; in the member voice channel
if(command === 'play'){
let song = await client.player.play(message.member.voice.channel, args[0])
message.channel.send(`Currently playing ${song.name}!`);
}
</code></pre>
<h3>Pause</h3>
<p>To pause the current song, use the <code>client.manager.pause()</code> function.</p>
<p><strong>Usage:</strong></p>
<pre class="prettyprint source lang-js"><code>client.player.pause(guildID);
</code></pre>
<p><strong>Example</strong>:</p>
<pre class="prettyprint source lang-js"><code>client.on('message', async (message) => {
const args = message.content.slice(settings.prefix.length).trim().split(/ +/g);
const command = args.shift().toLowerCase();
if(command === 'pause'){
let song = await client.player.pause(message.guild.id);
message.channel.send(`${song.name} paused!`);
}
});
</code></pre>
<h3>Resume</h3>
<p>To resume the current song, use the <code>client.manager.resume()</code> function.</p>
<p><strong>Usage:</strong></p>
<pre class="prettyprint source lang-js"><code>client.player.resume(guildID);
</code></pre>
<p><strong>Example</strong>:</p>

if(command === 'setvolume'){
client.player.setVolume(message.guild.id, parseInt(args[0]));
message.channel.send(`Volume set to ${args[0]} !`);
}
});
</code></pre>

let aSongIsAlreadyPlaying = client.player.isPlaying(message.guild.id);
// If there's already a song playing
if(aSongIsAlreadyPlaying){
// Add the song to the queue
let song = await client.player.addToQueue(message.guild.id, args[0]);
message.channel.send(`${song.name} added to queue!`);

message.channel.send('Queue cleared!');
}
});
</code></pre>
<h3>GetQueue</h3>
<p>To get the server queue, use the <code>client.player.getQueue()</code> function.</p>

<pre class="prettyprint source lang-js"><code>client.player.getQueue(guildID);
</code></pre>
<p><strong>Example:</strong></p>
<pre class="prettyprint source lang-js"><code>client.on('message', (message) => {
const args = message.content.slice(settings.prefix.length).trim().split(/ +/g);
const command = args.shift().toLowerCase();
if(command === 'queue'){
let queue = await client.player.getQueue(message.guild.id);
message.channel.send('Server queue:\n'+(queue.songs.map((song, i) => {
return `${i === 0 ? 'Current' : `#${i+1}`} - ${song.name} | ${song.author}`
}).join('\n')));
}
/**

song.queue.on('end', () => {
message.channel.send('The queue is empty, please add new songs!');
});
song.queue.on('songChanged', (oldSong, newSong) => {
message.channel.send(`Now playing ${newSong}...`);
});
}
</code></pre>
<h2>Handle errors</h2>
<p>There are 2 main errors that you can handle like this:</p>
<pre class="prettyprint source lang-js"><code>client.on('message', (message) => {
const args = message.content.slice(settings.prefix.length).trim().split(/ +/g);
const command = args.shift().toLowerCase();
// Error 1:
// Song not found
if(command === 'play'){
client.player.play(message.member.voice.channel, args[0]).then((song) => {
message.channel.send(`Currently playing ${song.name}!`);
}).catch(() => {
message.channel.send(`No song found for ${args[0]}`);
});
}
// Error 2:
// Not playing
if(command === 'queue'){
let playing = client.player.isPlaying(message.guild.id);
if(!playing) return message.channel.send(':x: No songs currently playing!');
// you are sure it works:
client.player.getQueue(message.guild.id);
}
});
