Setting a welcome channel Discord.js? - node.js

Question

Now there are a lot of tutorials on setting up welcome messages, and sending it once a member joins the guild, but they are only for custom servers, because look:
const applyText = (canvas, text) => {
const ctx = canvas.getContext('2d');
let fontSize = 70;
do {
ctx.font = `${fontSize -= 10}px sans-serif`;
} while (ctx.measureText(text).width > canvas.width - 300);
return ctx.font;
};
client.on('guildMemberAdd', async member => {
const channel = member.guild.channels.cache.find(ch => ch.name === '🚪welcome');
if (!channel) return;
const canvas = Canvas.createCanvas(700, 250);
const ctx = canvas.getContext('2d');
const background = await Canvas.loadImage('./GANG.jpg');
ctx.drawImage(background, 0, 0, canvas.width, canvas.height);
ctx.strokeStyle = '#74037b';
ctx.strokeRect(0, 0, canvas.width, canvas.height);
ctx.font = '45px Masked Hero Demo';
ctx.fillStyle = '#000000';
ctx.fillText('WELCOME,', canvas.width / 2.4, canvas.height / 3.5);
ctx.font = '45px Masked Hero Demo';
ctx.fillStyle = '#ffffff';
ctx.fillText('WELCOME,', canvas.width / 2.37, canvas.height / 3.6);
ctx.font = applyText(canvas, `${member.displayName}!`);
ctx.fillStyle = '#000000';
ctx.fillText(`${member.displayName}!`, canvas.width / 2.5, canvas.height / 1.57);
ctx.font = applyText(canvas, `${member.displayName}!`);
ctx.fillStyle = '#ffffff';
ctx.fillText(`${member.displayName}!`, canvas.width / 2.47, canvas.height / 1.6);
ctx.beginPath();
ctx.arc(125, 125, 100, 0, Math.PI * 2, true);
ctx.closePath();
ctx.clip();
const avatar = await Canvas.loadImage(member.user.displayAvatarURL({ format: 'jpg' }));
ctx.drawImage(avatar, 25, 25, 200, 200);
const attachment = new Discord.MessageAttachment(canvas.toBuffer(), 'GANG.jpg');
channel.send(`Welcome to the server, ${member}! Make sure to check info at <#743160115833864263>`, attachment);
});
At the part where it says 🚪welcome, that means any channel matching that name is where the message will send to.
But this would only work using a custom bot, and since I want everyone to use this, depending since they wont use 🚪welcome as their welcome channel name. How do I make it that a user sets a welcome channel and then welcome messages will send there?
Sorry, English is my second language.

Answer 1

You can simply set a variable (ex. welcomeChannel) equal to whatever the user wants their welcome channel to be and replace that with your 🚪welcome section.
Ex.
let welcomeChannel = "welcome" and then later on replace
const channel = member.guild.channels.cache.find(ch => ch.name === '🚪welcome');
with
const channel = member.guild.channels.cache.find(ch => ch.name === welcomeChannel);
Everything else will work just fine. If you wanted to create a command though to have the bot prompt it via messaging, that'll require a messageCollector. I'm not certain if that's what you're asking.
