Discordjs add space between prefix and command

Tags: , ,



I created a music bot that streams music when someone taps !play in-text channel

Now I want to switch !play with please play but it response only with pleaseplay with no space between them and when I tried to change the code:

const prefix = 'please'; //before
const prefix = 'please '; //after

but it doesn’t work at all with an error

log (node:5296) UnhandledPromiseRejectionWarning: Error: No video id found:

const {Client, Attachment, Message} = require('discord.js');
const {token} = require("./config.json");
const bot = new Client();
const prefix = 'please ';


const ytdl = require("ytdl-core");
const request = require('request');
const cheerio = require('cheerio');

const queue = new Map();



bot.on('ready', () => {
    console.log('Client is online!');

Answer

The problem is that your arguments are split based on the space character.

const args = message.content.split(" ");

args[1] is being referenced to get the text after the command name, but with the space in the command, args[1] will always be “play” (or whichever command they are using)

A quick fix would be to change args[1] to args[2]

const songInfo = await ytdl.getInfo(args[2]);
