discord-guard/src/captcha.js

A discord verifacation bot that uses a captcha.

const Jimp = require('jimp');
module.exports.createCaptcha = async function createCaptcha() {
    const captcha = Math.random().toString(36).slice(2, 8);
    const image = new Jimp(175, 50, 'white');
    const font = await Jimp.loadFont(Jimp.FONT_SANS_32_BLACK);
    const w = image.bitmap.width;
    const h = image.bitmap.height;
    const textWidth = Jimp.measureText(font, captcha);
    const textHeight = Jimp.measureTextHeight(font, captcha);
    image.print(font, (w / 2 - textWidth / 2), (h / 2 - textHeight / 2), captcha);
    image.write(`./Guard/Container/${captcha}.png`);
    return captcha;
}
