Wechaty.instance() // Global Instance
.on('scan', (qrcode, status) => console.log(`Scan QR Code to login: ${status}\nhttps://api.qrserver.com/v1/create-qr-code/?data=${encodeURIComponent(qrcode)}`))
.on('login',            user => console.log(`User ${user} logined`))

GETTING STARTED

Wechaty Starter Repository - https://github.com/wechaty/wechaty-getting-started

We have a Wechaty starter repository for beginners with the simplest setting. It will be just work out-of-the-box after you clone & npm install & npm start.

If you are new to Wechaty and want to try it the first time, we'd like to strong recommend you starting from this repository, and using it as your starter template for your project.

Otherwise, please saved the above The World's Shortest ChatBot Code: 6 lines of JavaScript example to a file named mybot.js before you can use either NPM or Docker to run it.

1. NPM

npm init
npm install wechaty

# create your first mybot.js file, you can copy/paste from the above "The World's Shortest ChatBot Code: 6 lines of JavaScript"
# then:
node mybot.js

2. Docker

Wechaty Starter Repository for Docker - https://github.com/wechaty/docker-wechaty-getting-started

Wechaty Docker supports both JavaScript and TypeScript. To use TypeScript just write in TypeScript and save with extension name .ts, no need to compile because we use ts-node to run it.

2.1. Run JavaScript

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

2.2. Run TypeScript

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

Learn more about Wechaty Docker at Wiki:Docker.

3. Switch Protocol(Puppet)

Wechaty is very powerful that it can run with different protocols. You can specify the protocol by set the environment variable WECHATY_PUPPET to different puppet provider.

Currently we support the following puppet providers:

Protocol	Puppet Provider	Environment Variable
Web	PuppetPuppeteer	`export WECHATY_PUPPET=wechaty-puppet-puppeteer`
iPad	PuppetPadchat	`export WECHATY_PUPPET=wechaty-puppet-padchat`
Mock	PuppetMock	`export WECHATY_PUPPET=wechaty-puppet-mock`
Web	PuppetWechat4u	`export WECHATY_PUPPET=wechaty-puppet-wechat4u`

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
Singapore	$3.5	512MB	Alipay, Wechat	Vultr

The Story

In 2017 ...

Huan's daily life/work depends on too much chat on wechat.

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

Can you imagine that? He was 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 he want to follow up(especially in a noisy room). ;-)

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