# Example

The shortest wechat bot code in the world: 6 lines JavaScript

```javascript
const { Wechaty } = require('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()
```

This bot can log all message to console. Source code(TypeScript version) at [here](https://github.com/wechaty/wechaty/blob/master/example/roger-bot.ts).

You can find more example from [Wiki](https://github.com/wechaty/wechaty/wiki/Example) and [Example Directory](https://github.com/wechaty/wechaty/blob/master/example/).

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 that most of them have more than 400 members.

Can you image 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 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.
