Captcha Generator
Captcha Generator is a Node library for quickly and easily generating captcha images that can be used through an authorized bot to verify human users on a chat platform such as Slack or Discord.
Installation
Use the package manager npm to install Captcha Generator
npm i @haileybot/captcha-generator
Usage
Basic:
// Import the module
const Captcha = require("@haileybot/captcha-generator");
// Create a new Captcha object - this will contain "PNGStream" and "value"
// - "PNGStream" is a stream of the image in PNG format
// - "value" is the 6 character code the image contains
let captcha = new Captcha();
Save to file example:
const Captcha = require("@haileybot/captcha-generator"),
fs = require("fs"),
path = require("path");
let captcha = new Captcha();
captcha.PNGStream.pipe(fs.createWriteStream(path.join(__dirname, `${captcha.value}.png`)));
Discord Example:
This example assumes you already have the core framework of a Discord Bot set up
const Captcha = require("@haileybot/captcha-generator");
// Use this function for blocking certain commands or features from automated self-bots
function verifyHuman(msg) {
let captcha = new Captcha();
msg.channel.send(
"**Enter the text shown in the image below:**",
new Discord.MessageAttachment(captcha.PNGStream, "captcha.png")
);
let collector = msg.channel.createMessageCollector(m => m.author.id === msg.author.id);
collector.on("collect", m => {
if (m.content.toUpperCase() === captcha.value) msg.channel.send("Verified Successfully!");
else msg.channel.send("Failed Verification!");
collector.stop();
})
}
