Brynjolf Events

Easily create Discord.js event listeners without needing a Client variable reference everytime, in Javascript or Typescript. Also includes a powerful listener decorator system that enables stateful, modular listener creation for Typescript users.

Features

  • 💊 Typescript decorators to convert classes into modular listeners
  • 🪩 Create Discord.js event listeners without Client
  • 🪶 Lightweight, zero dependencies
  • 🍰 Extremely easy to use
  • 🧩 Fully documented
  • ⭐ New * event emitted alongside all other events
  • 🧠 Built with Typescript, providing great IDE intellisense

Get Started

  1. Create a Discord.js client
  2. Install Brynjolf Events with npm install @brynjolf/events
  3. Run the quick example below, or skip the tutorial and jump right in

Quick Examples

Modular Listeners

⚠️ Requires Typescript >= v5

Using the power of decorators, you can easily create modular classes to handle events. A class can handle any number of events. The events are only handled once the class is constructed into an object. Unfortunately, Javascript does not officially support decorators yet, so this is a Typescript-only feature for the moment.

approver_example.ts:

import { listener } from "@brynjolf/events"
import type { Message } from "discord.js"

// Reacts with 👍 on the third message received
class MessageApprover {
    private messageCount: number = 0;

    @listener("messageCreate")
    onMessage(message: Message) {
        this.messageCount++;
        if (this.messageCount == 3) message.react("👍");
    }
}

// Construct
new MessageApprover();

index.ts:

import { events } from "@brynjolf/events"
import { Client, IntentsBitField } from "discord.js"

// Create Discord.js client
const client = new Client({ intents: [
    IntentsBitField.Flags.Guilds,
    IntentsBitField.Flags.GuildMessages
]});
client.login("YOUR TOKEN HERE");

// Set client in events system
events.client(client);

No-Client Listeners

✅ Works in Javascript or Typescript

Easily create event listeners without needing an immediate reference to a Client. Just supply a Client once in your main file, and all listeners will work.

message_example.js:

import { events } from "@brynjolf/events"

events.on("messageCreate", message => {
    message.reply("Hello there!");
});

index.js:

import { events } from "@brynjolf/events"
import { Client, IntentsBitField } from "discord.js"

// Import your event files
import "message_example.js";

// Create Discord.js client
const client = new Client({ intents: [
    IntentsBitField.Flags.Guilds,
    IntentsBitField.Flags.GuildMessages,
    IntentsBitField.Flags.MessageContent
]});
client.login("YOUR TOKEN HERE");

// Set client in events system
events.client(client);

All Event

✅ Works in Javascript or Typescript

The all (*) event is emitted when any other event is emitted, providing you the name of the emitted event and its arguments.

import { events } from "@brynjolf/events"

events.on("*", (eventName, args) => {
    console.log(`Event '${eventName}' was triggered.`);
});

// Message sent:
// => "Event 'messageCreate' was triggered."

// Slash command used:
// => "Event 'interactionCreate' was triggered."

// Message deleted:
// => "Event 'messageDelete' was triggered."

// And so on...

This obviously requires you to create a Discord.js Client and supply it via events.client(), just like the above examples.
