# The World's Shortest ChatBot Code: 6 lines of 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.

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/).

# Run

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

We have two options to run wechaty:

1. Docker
1. NPM

## Docker

[![Docker Pulls](https://img.shields.io/docker/pulls/zixia/wechaty.svg?maxAge=2592000)](https://hub.docker.com/r/zixia/wechaty/) [![Docker Stars](https://img.shields.io/docker/stars/zixia/wechaty.svg?maxAge=2592000)](https://hub.docker.com/r/zixia/wechaty/) [![Docker Layers](https://images.microbadger.com/badges/image/zixia/wechaty.svg)](https://microbadger.com/#/images/zixia/wechaty)

The **best practice** to use Wechaty is run by docker, becasue it's not only the most easy way to get start, but also protect you out of the troubles of dependencies problems. 

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

> Wechaty Docker support to run TypeScript directly as well: just write in TypeScript and save to `mybot.ts`.

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.
