How to count members belonging to a certain role in Discord.js bot?

Question

I'm trying to implement a function which messages the count of users assigned to a certain role. A few months ago this worked flawlessly, but after a certain update it just stopped working correctly.

let count = message.guild.members.filter(m => m.roles.find(r => r.name === roleName)).size;
message.channel.send(user + " Count of users in " + roleName + ": "+count);

My code now looks like this:

let count = message.guild.members.cache.filter(m => m.roles.cache.find(r => r.name === roleName)).size; //These commands are in a module export, message is an object passed as an argument into it
message.channel.send(user + " Count of users in " + roleName + ": "+count);

Easy to say it doesn't work and it usually returns count of users that recently messaged or interacted with the bot. I tried using various .fetch() but they just return:

UnhandledPromiseRejectionWarning: Error [GUILD_MEMBERS_TIMEOUT]: Members didn't arrive in time

...or something similair. I tried guild.members.fetch() / guild.fetch() and such. Any help would be appreciated.

Answer 1

You need to enable the SERVER MEMBERS INTENT in your application.

Answer 2

You dont need to fetch all users or enable server members intent for such a feature.

You can send GET request to https://discord.com/api/v8/guilds/<guildID>/roles/member-counts endpoint.

This will return a response like this:

{
    "538088986342719490": 1,
    "593404972922830848": 2,
    ...
    // "roleID": memberCount,
}

In Discord.js v13 + The Syntax is:

const Guild = message.guild;
let Rolecount = Guild.members.cache.filter(m => m.roles.cache.find(r => r.name === 'RoleNameHere')).size;
