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

```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 message to console.

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

# Getting Started

## A Great Live Coding Tutorial

<div align="center">
<a target="_blank" href="https://blog.chatie.io/guide/2017/01/01/getting-started-wechaty.html"><img src="https://cloud.githubusercontent.com/assets/1361891/21722581/3ec957d0-d468-11e6-8888-a91c236e0ba2.jpg" border=0 width="60%"></a>

The above 10 minutes video tutorial is a good start point if you are new to Wechaty.

## 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`.

Get to know more about Wechaty Docker at [Wiki:Docker](https://github.com/chatie/wechaty/wiki/Docker).

### NPM

[![NPM Version](https://badge.fury.io/js/wechaty.svg)](https://badge.fury.io/js/wechaty) [![Downloads][downloads-image]][downloads-url] [![Greenkeeper badge](https://badges.greenkeeper.io/Chatie/wechaty.svg)](https://greenkeeper.io/)

```shell
$ npm install wechaty

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

$ node mybot.js
```

## Find a Good Server

The best practice for runing 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 is used by ourselves, they worked perfectly in production. You can use the following link to get one in minutes, and also do this can support Wechaty because you are refered by us.

| Location  | Price | Ram     | Payment           | Provider |
| ---       | ---   | ---     | ---               | ---      |
| Singapore | $5    | 512MB   | Paypal            | [DigitalOcean](https://m.do.co/c/01a54778df5c) |
| Japan     | $5    | 1GB     | Paypal            | [Linode](https://www.linode.com/?r=5fd2b713d711746bb5451111df0f2b6d863e9f63) |

# Todo

* [ ] Use Dependency Injection for FriendRequest(etc)

* [ ] [Generating Documentation for TypeScript Projects](https://blog.cloudflare.com/generating-documentation-for-typescript-projects/)

Documentation
-------------

In order to sync the doc with the lastest code for best, Wechaty use [jsdoc](http://usejsdoc.org/) to descript API, and use [jsdoc-to-markdown](https://github.com/jsdoc2md/jsdoc-to-markdown/wiki) to generate markdown format document to [docs](docs/index.md) directory.

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.
