• How to make a basic youtube music bot work with searching titles instead of the URL

  21 janvier 2021, par Brandon

  Hello so i've followed this tutorial and added this code to my current bot to make it have a music bot function. Im wondering how to make the following code work with the youtube search function, for example right now I have to do !play URL but I would also like to be able to do !play name of song then the bot will search and play the most matched song.

  



  I am new to javascript but I know I shouldn't be looking for handouts, but some help would be appreciated.

  



  const Discord = require("discord.js");
const { prefix, token } = require("./config.json");
const ytdl = require("ytdl-core");

const client = new Discord.Client();

const queue = new Map();

  console.log("Ready!");
});

client.once("reconnecting", () => {

    skip(message, serverQueue);
    return;
