🎓 Discord.js Captcha 🎓

A powerful package for Discord.js v13 that allows you to easily create CAPTCHAs for Discord Servers.

What is a CAPTCHA?

Put simply, a CAPTCHA is a question you have to answer to prove you are not a robot.

CAPTCHA is an acronym for:

Completely

Automated

Public

Turing Test (to tell)

Computers (and humans)

Apart

To learn more about what a CAPTCHA is, you can watch this video by Tom Scott.

Install Package

To install this awesome module, type the command shown below into your Terminal.

npm i discord.js-captcha --save

For versions 2.0.0 and Above, you'll also need discord.js v13.

npm i discord.js@13 --save

For versions earlier than 2.0.0, you'll need discord.js v12. However it is recommended you update to gain access to more customisation options, as well as to patch bugs and security vulnerabilities.

npm i discord.js@12 --save

Example Code

const { Client, Intents, MessageEmbed } = require("discord.js");
const client = new Client({ intents: [Intents.FLAGS.GUILDS, Intents.FLAGS.GUILD_MESSAGES, Intents.FLAGS.GUILD_MEMBERS, Intents.FLAGS.DIRECT_MESSAGES] });
const { Captcha } = require("discord.js-captcha");

const captcha = new Captcha(client, {
    guildID: "Guild ID Here",
    roleID: "Role ID Here",
    channelID: "Text Channel ID Here", //optional
    sendToTextChannel: false, //optional, defaults to false
    kickOnFailure: true, //optional, defaults to true. whether you want the bot to kick the user if the captcha is failed
    caseSensitive: true, //optional, defaults to true. whether you want the captcha responses to be case-sensitive
    attempts: 3, //optional, defaults to 1. number of attempts before captcha is considered to be failed
    timeout: 30000, //optional, defaults to 60000. time the user has to solve the captcha on each attempt in milliseconds
    showAttemptCount: true, //optional, defaults to true. whether to show the number of attempts left in embed footer
    customPromptEmbed: new MessageEmbed(), //customise the embed that will be sent to the user when the captcha is requested
    customSuccessEmbed: new MessageEmbed(), //customise the embed that will be sent to the user when the captcha is solved
    customFailureEmbed: new MessageEmbed(), //customise the embed that will be sent to the user when they fail to solve the captcha
});

client.on("guildMemberAdd", async member => {
    //in your bot application in the dev portal, make sure you have intents turned on!
    captcha.present(member);
});

client.login("Discord Bot Token")

Note: When displaying a CAPTCHA to the user, the CAPTCHA image will automatically be attached to the customPromptEmbed for you.

In addition, if you have the showAttemptCount option enabled, any embed footer text on the customPromptEmbed will be overwritten with the number of attempts left.

channelID Option Explained

The channelID option is the ID of the Discord Text Channel to Send the CAPTCHA to if the user's Direct Messages are locked.

Use the option sendToTextChannel, and set it to true to always send the CAPTCHA to the Text Channel.

sendToTextChannel Option Explained

The sendToTextChannel option determines whether you want the CAPTCHA to be sent to a specified Text Channel instead of Direct Messages, regardless of whether the user's DMs are locked.

Use the option channelID to specify the Text Channel.

CAPTCHA Events

There are five events that you can use to log CAPTCHA actions, responses, and other details. They are:

• prompt - Emitted when a CAPTCHA is presented to a user.
• answer - Emitted when a user responds to a CAPTCHA.
• success - Emitted when a CAPTCHA is successfully solved.
• failure - Emitted when a CAPTCHA is failed to be solved.
• timeout - Emitted when a user does not solve the CAPTCHA in time.

All of these events are emitted by the Captcha class. Here's an example of how to use them:

captcha.on("success", data => {
    console.log(`A Member has Solved a CAPTCHA!`);
    console.log(data);
});
