erela.js - Updated & Improved by BENx2115

An up to date Lavalink Wrapper, which makes it easy to use Lavalink within your Discord Bot!
- Works in Typescript, CommonJS and ModuleJS
- Made for discord.js, but works in discordeno (example), eris, oceanic and many other libraries too!
- Supports Regioning (e.g: Picking a USA Node for USA Voice Channel Regions)
- Supports Latest Lavalink Version (v3.7) [REST API]
- Inbuilt Filters
- Many Settings like: instaFilterFix, volumeDecrementer, etc. which makes using it way easier!

Maintained + improved Fork from the official menudocs/erela.js repository!

Within this Repository, I did:
- updated erela.js to support Latest Lavalink Features (Sessions, REST-API, etc.)
- Added new Features

$3

Or shortly said here:
1. Download the latest .jar File-Release from the releases page of the Lavalink Repository
2. Download the example Application.yml file from the official Example and put it in the same directory as your Lavalink.jar file (note it __must be__ named: application.yml)
3. Adjust the settings of your Lavalink Server in the file called: application.yml: Port, Password are the most important ones! (they are used to connect to it via erela.js)
4. Start the Lavalink-Server with a terminal by typing: java -jar Lavalink.jar within that directory!

Everything about Nodes:

$3

You tell the Manager in it's ManagerOptions, which Nodes it shall use:
`js
client.musicManager = new Manager({
...ManagerOptions,
nodes: [ { identifier: "MyNode1", host: "localhost", port: 2333, password: "youshallnotpass", version: "v3", useVersionPath: true, secure: false, } ]
})
`
You can pass multiple Nodes too, if you do so the identifier Property is very Important!
How to create a Node after Manager-Creation?
`js
client.musicManager.createNode({ identifier: "MyNode3", host: "localhost", port: 2333, password: "youshallnotpass", version: "v3", useVersionPath: true, secure: false });
`

$3

| Variable-Name | Value | Default | Description |
|-----------------|---------------------|-------------------|---------------------------------------------------------------------------------------------------|
| host | string | - | The Hostname / Ipaddress of your Lavalink-Node |
| port | number | 2333 | The Port of the Node |
| password | string | "youshallnotpass" | The Authentication Creditentals aka Password |
| secure | boolean | false | If it shall use Port 443 and https |
| identifier | string | - | The identifier of the Node (for your manager#nodes Collection key) |
| retryAmount | number | 5 | How often it shall retry to connect on fails |
| retryDelay | number | 30e3 | How long to wait between each retry |
| requestTimeout | number | 10e3 | How long to wait until a REST-Request gets rejected |
| poolOptions | undici.Pool.Options | - | The Undici Pool Options |
| regions | string[] | - | Discord Voice Regions array (for that node) to support regioning |
| version | "v2" | "v3" | - | Lavalink Version (use v3 for REST API) |
| useVersionPath | boolean | - | If it should use the path while making Requests (if your lavalink node is on v2 make it on false) |

$3


The Default Node is beeing used, when no node is provided while creating the Manager
-> You can also see it as an "example" of Node Data
`js
{
identifier: "default",
host: "localhost",
port: 2333,
password: "youshallnotpass",
secure: false,
retryAmount: 5,
retryDelay: 30e3,
requestTimeout: 10e3,
version: "v3",
useVersionPath: true, // should be set on true, to use the latest rest api correctly!
}

Examples & Tutorials

Regioning System:

When creating the node(s) pass the variable regions, to auto-select the right region based on what region u provide in the players.create(options#region) options!


`js
const nodes = [
  {
    identifier: "USA_NODE", host, password, port, version: "v3", useVersionPath: true,
    regions: ["us-east", "us-central", "us-south", "us-west", "brazil"],
  },
  {
    identifier: "GERMANY_NODE", host, password, port, version: "v3", useVersionPath: true,
    regions: ["rotterdam", "russia"],
  },
]
`

When creating the Player, pass the rtcRegion like that:

`js
const { channel } = message.member.voice;
const player = client.musicManager.create({
  region: channel?.rtcRegion || undefined, // region
  guild: channel.guild.id,
  voiceChannel: channel.id,
  textChannel: message.channel.id,
  selfDeafen: true,
});

// searching tracks requires you to pass the node now!
client.musicManager.search(query, requester, player.node);


// or search via player, so you don't need to pass the node:
player.search(query, requester);
`


IMPORTANT NOTE!
> When using regioning, you must SEARCH on the same NODE as you play the TRACK on, best practice can be found in the JS script above for the search() method, just provide the correct node (the node the player is using)

*



$3

> Lavalink provides default sources from: scsearch, ytsearch, ytmsearch, so that you don't need to type these weird names, you can simply type soundcloud or youtube or youtube music.
> However since Lavalink supports Plugins too, you can now also use them to search on things like: Spotify, Deezer, etc. Use the LavaSrc Plugin for that!
> -> so you can also pass as a source spotify, or short: sp
> Check out SearchPlatforms to figure what all you can use!

`js

const source = "yt"; // "yt" / "ap" / "sp" / "sc" / "ytm" / "..."
// request possibility
client.musicManager.search({query, source}, requester, player.node);
// e.g. search on spotify
client.musicManager.search({
   query: "Adele - Hello",
   source: "spotify", // "sp"/ "spsearch" / "sprec" / etc. check out: SearchPlatforms on what you can all use!
   // or for deezer: source: "dz" / "deezer"
}, interaction.user, player.node);
`

How to make filters apply instantly

Added the Player-Create-Property #instaUpdateFiltersFix
Updates filters and Equalizers almost instantly, by seeking to the same player position after a filter/eq got applied
-> On default it's set to: true aka enabled, if your system is not able to handle the extra load, disable it!

`js
const player = client.musicManager.create({
    ...PlayerOptions,
    instaUpdateFiltersFix: true, // to disable it (and save resources) set it to false
})
`

Update the Player Position way faster!

Lavalink sends the Player Stats (Position) every 5s. With the newest Lavalink Version you can adjust that, however if it's less than 2s your CPU Usage goes crazy high!!
-> To make it simpler, you can count the position on your Manager!
-> the default value is: 250 (in ms) to adjust / change that, do it with:

`js
new Manager({
    ...ManagerOptions,
    position_update_interval: 150
})
`

It is client sided, not server sided, means, that on your client player.position will be more accurate, if the server changes, the client will be updated either way by the server (real) data.


Added Manager#Property: volumeDecrementer

// e.g: new Manager({volumeDecrementer:0.75}); will send to lavalink 75% of the volume not 100%, aka you will hear 75% of the set volume, tho see in the player.volume property the full 100% aka if you do player.setVolume(100); then player.volume == 100 but lavalink receives 75

- I use smt between 0.5 - 0.75 cause then the volume is not TOO LOUD at 100% (default) and not really earrapy at 150% (which users like to do when trolling ;) ) (for reference 1 is the same as not adding the option)




This lib works for many discord Libs

I tested it in: discord.js, discordeno, oceanicJS, eris.
-> U just have to be sure, to pass all IDs as STRINGS (as that'S discord.js's default caching value-type)

Inbuilt Filters

Variables to see which Filter is active:
`js

player.filters.nightcore // READONLY - {Boolean|String} if it's enabled or not
player.filters.rotating // READONLY - {Boolean} if it's enabled or not
player.filters.tremolo // READONLY - {Boolean} if it's enabled or not
player.filters.vibrato // READONLY - {Boolean} if it's enabled or not
player.filters.lowPass // READONLY - {Boolean} if it's enabled or not
player.filters.karaoke // READONLY - {Boolean} if it's enabled or not
player.filters.audioOutput // READONLY - {"stereo"|"mono"|"right"|"left"} how the audio is getting outputted

// only available with lavalink-filter-plugin
player.filters.echo // READONLY - {Boolean} if it's enabled or not

`

Functions to set the Filters:
> -> You can even use custom Data if you want, just pass them to the function parameter(s)!
`js

player.toggleRotating(rotationHz = 0.2);
player.toggleVibrato(frequency = 2, depth = 0.5);
player.toggleTremolo(frequency = 2, depth = 0.5);
player.toggleLowPass(smoothing = 20);
player.toggleNightcore(speed = 1.2999999523162842, pitch = 1.2999999523162842, rate=1);
player.toggleKaraoke(level = 1, monoLevel = 1, filterBand = 220, filterWidth = 100);
// default: stereo, rightChannel is right 100% and left 0%, and leftChannel is invert of rightChannel
player.setAudioOutput("stereo"|"mono"|"right"|"left");

// reset all filters to default
player.resetFilters();

// only available with lavalink-filter-plugin
player.toggleEcho(delay = 1, decay = 0.5);
`

Added Manager#validUnresolvedUris for unresolved tracks


- If an unresolved Track is saved from lavalink plugins, like spotify and u wanna search on spotify with that uri, then u should do this:

`js

const Manager = new Manager({
    ...,
    validUnresolvedUris: ["spotify.com"]
})

`




Added Manager#forceLoadPlugin for forcing plugin loadings

If you get errors like does not extend plugin, then you can do this to force load it!

`js
const Manager = new Manager({
    ...,
    forceLoadPlugin: true,
})
`




Added manager.init("clientId", { clientId, clientName, shards });

This allows it, that you can add data from the client once you init the manager!
Like clientName or shards Count, you should init the manager either way, once it's ready!

Added More player parameters:

 - player.createdAt Date object, when the player was created in LAVALINK
 - player.createdTimeStamp Date Timestamp in MS, when the player was created in LAVALINK
 - player.connected Lavalink connected state, if it's true, lavalink thinks player is connected...
 - player.payload Last payload from playerUpdate Event lavalink sent
 - player.ping Ping in ms from Lavalink server. if it's less then 0, it means player is not connected yet
 - player.wsPing Ping in ms from Lavalink server. if it's less then 0, it means player is not connected yet

Added Link (Url) Query Validation:


- Manager#onlyAllowAllowedLinks --> must be true to make it work (default: true)
 - Manager#allowedLinks Array of Strings of Urls which are allowed
 - Manager#allowedLinksRegexes Array of Regexes which must match the link
    - Manager#regex --> Default Regexes applied to allowedLinksRegexes, if not Set (except spotify and deezer links)
If provided link to query is not valid, then it throws an error,

e.g.

`js

new Manager({

  allowedLinksRegexes: [

    Manager.regex.YoutubeRegex,

    Manager.regex.YoutubeMusicRegex,

    Manager.regex.SoundCloudRegex,

    Manager.regex.SoundCloudMobileRegex,

    // Manager.regex.AllDeezerRegex,

    // Manager.regex.AllSpotifyRegex,

    Manager.regex.mp3Url,

    Manager.regex.m3uUrl,

    Manager.regex.m3u8Url,

    Manager.regex.mp4Url,

    Manager.regex.m4aUrl,

    Manager.regex.wavUrl,

    //Manager.regex.vimeo,

    //Manager.regex.TwitchTv,

    //Manager.regex.appleMusic,

    //Manager.regex.bandcamp,

    //Manager.regex.radiohost,

    //Manager.regex.yandexmusic,

  ] // these are the default Values with comments, are all available, you can add your custom regexes if you want like this: /regex/ or new RegExp("regex", "flags");

})

// or: accept all the provided regexes:

new Manager({

  ...,

  allowedLinksRegexes: Object.values(Manager.regex),

})

`
