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}`))
.init()

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.

GETTING STARTED

A Great Live Coding Tutorial

The above 10 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

Run

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

We have two options to run wechaty:

Docker
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

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.

Run JavaScript

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

Run TypeScript

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

NPM

$ npm install wechaty

$ cat > mybot.js <<'_EOF_'
const { Wechaty } = require('wechaty')
const bot = Wechaty.instance()
console.log(bot.version())
_EOF_

$ node mybot.js

TEST

Wechaty uses AVA for unit testing

To test Wechaty, run:

npm test

DOCUMATAION

In order to sync the doc with the lastest code, it's best to use jsdoc to describe the API, and use jsdoc-to-markdown to generate markdown format documents to the docs directory.

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

CONTRIBUTING

Howto contribute

Contributions in any form are highly encouraged and welcome! Be it new or improved presets, optimized streaming code or just some cleanup. So start forking!

Code Contributions

If you want to add new features or change the API, please submit an issue first to make sure no one else is already working on the same thing and discuss the implementation and API details with maintainers and users by creating an issue. When everything is settled down, you can submit a pull request.

When fixing bugs, you can directly submit a pull request.

Make sure to add tests for your features and bugfixes and update the documentation (see below) before submitting your code!

Join Wechaty Developers' Community

Wechaty is used in many ChatBot projects by hundreds of developers. If you want to talk with other developers, just scan the following QR Code in WeChat with secret code wechaty, you can join our Wechaty Developers' Home at once.

Scan now, because other Wechaty developers want to talk with you too! (secret code: wechaty)

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.
