Usage

Listener

All listener provide a same interface to operate. You can use it like this:

// it is psudocode
const listener = new Listener(message, { collectorOptions });
listener.on("collect", (arg) => console.log("collect", arg));
listener.on("collectError", (error) => console.log(error));
listener.on("end", (collected, reason) => console.log("listenerEnd"));
await listener.start(); // it would perform some required action

ActionRowMessageListener

import { ActionRowMessageListener } from "discord.js-message-listener";

ActionRowMessageListener provide a simple way to create action rows and listen to them. To use it, you need to pass a message, and a list of action row to it. It will edit the message to show the action row and listen to it.

const messageActionRow = new ActionRowBuilder();
const btn1 = new ButtonBuilder();
const btn2 = new ButtonBuilder();
btn1.setLabel("1");
btn2.setLabel("2");
messageActionRow.addComponents(btn1, btn2);
const listener = new ActionRowMessageListener(message, {
  messageActionRows: [messageActionRow],
  collectorOptions: {
    time: 10000,
  },
});
listener.on(
  "collect",
  // use as to cast to subclass of Interaction
  (arg) => console.log((arg as ButtonInteraction).customId)
);
await listener.start();

Utility

Paginator

import { Paginator } from "discord.js-message-listener";

Paginator provide a simple way to create paginator. It need a message listener to listen to the message. The other thing you need to do is to pass filter functions to it. Because the paginator accept any listener, you can use it flexibly.

The paginator will bind collect event to the listener for you, so you don't need to do it manually.

const messageActionRow = new ActionRowBuilder();
const prevPage = new ButtonBuilder();
const nextPage = new ButtonBuilder();
prevPage.setLabel("Prev");
prevPage.setCustomId("prev-btn");
nextPage.setLabel("Next");
nextPage.setCustomId("next-btn");
messageActionRow.addComponents(prevPage, nextPage);
const listener = new ActionRowMessageListener(msg, {
  messageActionRows: [messageActionRow],
  collectorOptions: {
    time: 60000,
  },
});
const page1 = new EmbedBuilder();
const page2 = new EmbedBuilder();
page1.setTitle("Page 1");
page2.setTitle("Page 2");
const pages = [page1, page2];
const paginator = new Paginator(listener, {
  pages,
  nextPageFilter: (arg) => (arg as ButtonInteraction).customId === "next-btn",
  previousPageFilter: (arg) =>
    (arg as ButtonInteraction).customId === "prev-btn",
});
// you should call start() to start the paginator
// start() will call listener.start() for you
await paginator.start();

You can also bind error handler and end handler to the paginator.

Error handler and end handler will be bind to the listener.

const paginator = new Paginator(listener, {
  pages,
  nextPageFilter: (arg) => (arg as ButtonInteraction).customId === "next-btn",
  previousPageFilter: (arg) =>
    (arg as ButtonInteraction).customId === "prev-btn",
  errorHandler: (error) => {
    // to something
    console.log(error);
  },
  endHandler: (collected, reason) => {
    // to something
    console.log(reason);
  },
});
