Lavalink Intallation Guide

Usage

Once the installation process is complete, we can import the NecordLavalinkModule into the root AppModule:

import { NecordLavalinkModule } from '@necord/lavalink';
import { Module } from '@nestjs/common';
import { Client } from 'discord.js';
import { AppUpdate } from './app.update';

@Module({
    imports: [
        NecordLavalinkModule.forRoot({
            nodes: [
                {
                    authorization: 'youshallnotpass',
                    host: 'localhost',
                    port: 2333,
                    id: 'main_node'
                }
            ]
        })
    ],
    providers: [AppUpdate]
})
export class AppModule {
}

Then create app.update.ts file and add OnLavalinkManager/OnceLavalinkManager decorators for handling LavalinkManager events and OnNodeManager/OnceNodeManager decorators for handling NodeManager events:

import { Injectable, Logger } from '@nestjs/common';
import { Context } from 'necord';
import { OnLavalinkManager, OnNodeManager, LavalinkManagerContextOf, NodeManagerContextOf } from '@necord/lavalink';

@Injectable()
export class AppUpdate {
    private readonly logger = new Logger(AppUpdate.name);

    @OnNodeManager('connect')
    public onReady(@Context() [node]: NodeManagerContextOf<'connect'>) {
        this.logger.log(`Node: ${node.options.id} Connected`);
    }

    @OnLavalinkManager('playerCreate')
    public onPlayerCreate(@Context() [player]: LavalinkManagerContextOf<'playerCreate'>) {
        this.logger.log(`Player created at ${player.guildId}`);
    }
}

Whenever you need to handle any event data, use the Context decorator.
