How to get role in Discord.js?

Question

This is my first Discord bot, so please bear with me if this is dumb!

I've been trying to find a way to get a role, either by name or by ID. Most tutorials that I've found are in line with:

// get role by ID

let myRole = message.guild.roles.get('264410914592129025');

// get role by name

let myRole = message.guild.roles.find((role) => role.name === 'Moderators');

Source: https://anidiots.guide/understanding/roles

Yet I keep getting a ReferenceError: message is not defined error.

Here is my code:

const token = '';

const prefix = '!!';

let role = message.guild.roles.find((role) => role.name === 'among us');

My goal is to just actually take the "among us" role and mute the mics for everyone with that role.

//prefix manager
bot.on('message', (message) => {
 //exit and stop if no pref
 if (!message.content.startsWith(prefix)) return;

 var args = message.content.substring(prefix.length).split(' ');

 //if !! is used
 switch (args[0]) {
  case 'bing':
   message.reply('bong');
   break;

  case 'HEY':
   message.reply(boulderHello[Math.floor(Math.random() * boulderHello.length)]);
   break;

  case 'muteall':
   role.voice.setMute(true);
   break;
 }
});

Answer 1

Okay so if something is not defined just define it like so:

const token = '';

const prefix = "!!";


//if it says: can't read property of bot of undefined use client.on instead


bot.on("message", (message) => {
let role = message.guild.roles.find(role => role.name === "among us");

//your code here
})

The Message is not defined by default. It is defined within the message event of Client as the first parameter.

Here's an example of how to get the role within the message event:

client.on("message", message => {
    const Role = message.guild.roles.cache.find(role => role.name == "among us");

    // You can also get the role by ID like this:
    const Role = message.guild.roles.cache.get("RoleID");
});

Answer 3

You need to put message in a message event.

bot.on(`message`, message => {
  //here you can have your code
});

As for finding the role, it's been updated in v12, so you need to do:

let role = message.guild.roles.cache.get(`id`)

And to get it by name:

let role = message.guild.roles.cache.get(r => r.name === `name`)
