Implementation

Start by creating a new Manager passing an array of nodes and an object with user the client's user id.

// import the Manager class from lavacord
const { Manager } = require("lavacord");

// Define the nodes array as an example
const nodes = [
    { id: "1", host: "localhost", port: 2333, password: "youshallnotpass" }
];

// Initilize the Manager with all the data it needs
const manager = new Manager(nodes, {
    user: client.user.id, // Client id
    send: (packet) => {
        // this needs to send the provided packet to discord's WS using the method from your library.
        // use the bindings for the discord library you use if you don't understand this
    }
});

// Connects all the LavalinkNode WebSockets
await manager.connect();

// The error event, which you should handle otherwise your application will crash when an error is emitted
manager.on("error", (error, node) => {
    error, // is the error
    node // is the node which the error is from
});

Resolving tracks using LavaLink REST API

const { Rest } = require("lavacord");

async function getSongs(search) {
    // This gets the best node available, what I mean by that is the idealNodes getter will filter all the connected nodes and then sort them from best to least beast.
    const node = manager.idealNodes[0];

    return Rest.load(node, search)
        .catch(err => {
            console.error(err);
            return null;
        });
}

getSongs("ytsearch:30 second song").then(songs => {
    // handle loading of the tracks somehow ¯\_(ツ)_/¯
});

Joining and Leaving channels

// Join
const player = await manager.join({
    guild: guildId, // Guild id
    channel: channelId, // Channel id
    node: "1" // lavalink node id, based on array of nodes
});

await player.play(track); // Track is a base64 string we get from Lavalink REST API

player.once("error", error => console.error(error));
player.once("end", data => {
    if (data.type === "TrackEndEvent" && data.reason === "replaced") return; // Ignore replaced reason to prevent skip loops
    // Play next song
});

// Leave voice channel and destroy Player
await manager.leave(guildId); // Player ID aka guild id
