The World's Shortest ChatBot Code: 6 lines of JavaScript

const { Wechaty } = require('wechaty') // import { Wechaty } from 'wechaty'

Wechaty.instance() // Singleton
.on('scan', (url, code) => console.log(`Scan QR Code to login: ${code}\n${url}`))
.on('login',       user => console.log(`User ${user} logined`))
.on('message',  message => console.log(`Message: ${message}`))

Notice: Wechaty requires Node.js version >= 6.9.0

This bot can log all messages to the console.

You can find more examples from Wiki and Example Directory.


A Great Live Coding Tutorial

The above 15 minute video tutorial is a good start point if you are new to Wechaty.

Source code in the video can be found at: Wechaty Starter Repository


Let's say, you have saved the above six line javascript example to mybot.js.

We have two options to run wechaty:

  1. Docker
  2. NPM

Notice: The published versions have always passed the CI tests. We highly recommend running wechaty with the versions installed by docker or npm instead of the latest master branch unless you are prepared to deal with the broken code problems.


Docker Pulls Docker Stars Docker Layers

The best practice to use Wechaty is running with docker, because it's not only the most easy way to get started, but also protects you from the troubles of dependency problems.

Wechaty Docker supports both JavaScript and TypeScript. To use TypeScript just write in TypeScript and save with extension name .ts.

Get to know more about Wechaty Docker at Wiki:Docker.

  1. Run JavaScript
$ docker run -ti --rm --volume="$(pwd)":/bot zixia/wechaty mybot.js # for JavaScript
  1. Run TypeScript

Find a Good Server

The best practice for running Wechaty Docker/NPM is using a VPS(Virtual Private Server) outside of China, which can save you hours of time because npm install and docker pull will run smoothly without any problem.

The following VPS providers are used by the Wechaty team, and they worked perfectly in production. You can use the following link to get one in minutes. Also, doing this can support Wechaty because you are referred by us.

Location Price Ram Payment Provider
Singapore $5 512MB Paypal DigitalOcean
Japan $5 1GB Paypal Linode
Korea $10 1GB Alipay, Paypal Netdedi

Future Improvements

Wechaty is far from perfect. The following things should be addressed in the future:

  • PuppetWine - Use DLL Inject to hook Windows Wechat Application, run from wine inside docker.
  • PuppetAndroid - Use Xposed to Hook Android Pad version of Wechat App, run from android emulator inside docker.

My Story

My daily life/work depends on too much chat on wechat.

  • I almost have 14,000 wechat friends in May 2014, before wechat restricts a total number of friends to 5,000.
  • I almost have 400 wechat rooms, and most of them have more than 400 members.

Can you imagine that? I'm dying...

So a tireless bot working for me 24x7 on wechat, monitoring/filtering the most important message is badly needed. For example, it highlights discussion which contains the KEYWORDS which I want to follow up(especially in a noisy room). ;-)

At last, It's built for my personal study purpose of Automatically Testing.
