I was willing to add all the members in GSoC WeChat room today. But I thought it so clumsy after sending 10 friend requests mannually. So I wrote this simple script to help me.

bot.ts:

import {Wechaty, Room, FriendRequest} from "wechaty";

Wechaty.instance()
    .on('scan', (url, code) => {
      let loginUrl = url.replace('qrcode', 'l');
 require('qrcode-terminal').generate(loginUrl);

        if (random > 0) {
            throw new NullPointerException("BufferedImage cannot be null");
        }
        final int sData;
        switch ((int) Math.random()) {
        case 0:
            sData = 0;
