Install

Requirements

NPM

Yarn

Example of usage

const Discord = require('discord.js')
const { ReactionController } = require('discord.js-reaction-controller')

const client = new Discord.Client()

client.on('message', message => {
  if (message.content.startsWith('>pagination')) {
    const controller = new ReactionController(client)

    controller
      .addReactionHandler('🤔', (reaction) => {
        reaction.message.channel.send('thinking')
          .catch(console.error)
      })

    controller.addPages([
      new Discord.MessageEmbed().setImage('https://github.com/yyx990803.png'),
      new Discord.MessageEmbed().setImage('https://github.com/egoist.png'),
      new Discord.MessageEmbed().setImage('https://github.com/vercel.png'),
      new Discord.MessageEmbed().setImage('https://github.com/Google.png'),
      new Discord.MessageEmbed().setImage('https://github.com/Microsoft.png')
    ])

    controller.sendTo(message.channel, message.author)
      .catch(console.error)
  }
})

client.login()
  .catch(console.error)

Using Promise (Lazy Loading)

It is recommended to create a function that returns MessageEmbed with Promise and put it in the argument of addPages and addPage when there are many processes to access externally through the network.

That way, "discord.js-reaction-controller" will resolve the promises as needed and cache and display the MessageEmbed.

const { Client, MessageEmbed } = require('discord.js')
const { ReactionController } = require('discord.js-reaction-controller')
const { getBasicInfo } = require('ytdl-core')

const client = new Client()

const fetchYouTubeVideoInfo = videoUrl => async () => {
  const { videoDetails } = await getBasicInfo(videoUrl)

  return new MessageEmbed()
    .setColor('RED')
    .setTitle(videoDetails.title)
    .setURL(videoDetails.video_url)
    .setImage(videoDetails.thumbnails[videoDetails.thumbnails.length - 1].url)
    .setTimestamp(Date.parse(videoDetails.publishDate))
    .setFooter('Uploaded on')
    .setAuthor(videoDetails.author.name, videoDetails.author.thumbnails[0].url, videoDetails.author.channel_url)
}
