## Wechaty had rewritten to Typescript.

Details: https://github.com/wechaty/wechaty/issues/40

```diff
+ Typescriptilized ...
+ on 12th Oct 2016
```

[VSCode](https://code.visualstudio.com/) is recommended as developing IDE for typescript because we can get the benefit of [intelligent code completion, parameter info, and member lists](https://code.visualstudio.com/docs/languages/javascript).

The last Javascript version is: [v0.4.0](https://github.com/wechaty/wechaty/releases/tag/v0.4.0) (2016/10/9) , or install v0.4 by `npm install wechaty`.

### Benifits from Typescript

- [Why we decided to move from plain JavaScript to TypeScript for Babylon.js](https://www.eternalcoding.com/?p=103)
- [Migrating from JavaScript](https://www.typescriptlang.org/docs/handbook/migrating-from-javascript.html)

# Examples
Wechaty is dead easy to use: 6 lines javascript for your wechat bot.

## 1. Basic: 6 lines
The following 6 lines of code implement a bot who can log all message to console:

```typescript
import Wechaty from 'wechaty'

Wechaty.instance() // Singleton
.on('scan', (url, code) => console.log(`Scan QrCode to login: ${code}\n${url}`))
.on('login',       user => console.log(`User ${user} logined`))
.on('message',  message => console.log(`Message: ${message}`))
.init()
```

Notice that you need to wait a moment while bot tries to get the login QRCode from Wechat. As soon as the bot gets login QRCode URL, he will print URL out. You need to scan the QR code on wechat and confirm login.

After that, the bot will be on duty. (roger-bot source can be found at [here](https://github.com/wechaty/wechaty/blob/master/example/roger-bot.js))

## 2. Advanced: dozens of lines
Here's a chatbot [ding-dong-bot](https://github.com/wechaty/wechaty/blob/master/example/ding-dong-bot.js) who can reply _dong_ when receives a message _ding_.

## 3. Hardcore: hundreds of lines
Here's a chatbot [api-ai-bot](https://github.com/wechaty/wechaty/blob/master/example/api-ai-bot.js), who can slightly understand NLP.

Natural Language Understanding enabled by [api.AI](https://api.ai), you can get your module on api.AI by its free plan.

# Deploy

Use docker to deploy wechaty is highly recommended.

## Deploy with 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)

[![dockeri.co](http://dockeri.co/image/zixia/wechaty)](https://hub.docker.com/r/zixia/wechaty/)

Wechaty is fully dockerized. So it will be very easy to be deployed as a MicroService. 

```bash
export TOKEN="your token here"

docker run -e WECHATY_TOKEN="$TOKEN" wechaty/wechaty
```

`WECHATY_TOKEN` is required here, because you need this key to managing wechaty on the chatbot cloud manager: https://www.wechaty.io

### Build

```bash
docker build -t wechaty .
```

### Ship

Wechaty can be used via Container as a Service

* [Arukas Cloud](https://arukas.io/en/) - Hosting Docker Containers(Currently in Beta, provide up to 10 **free containers**)
* [Docker Cloud](https://cloud.docker.com/) - Docker Cloud is a hosted service that provides a Registry with the build and testing facilities for Dockerized application images, tools to help you set up and manage your host infrastructure, and deployment features to help you automate deploying your images to your infrastructure.
* [Dao Cloud](https://www.daocloud.io/) - 容器云平台

## Deploy with Heroku

To Be Fix

~~Follow [these instructions](https://wechaty.readme.io/docs). Then, [![Deploy to Heroku](https://www.herokucdn.com/deploy/button.sv
g)](https://heroku.com/deploy)~~


# Installation

## Install from NPM

[![npm version](https://badge.fury.io/js/wechaty.svg)](https://badge.fury.io/js/wechaty)
[![Downloads][downloads-image]][downloads-url]

Use NPM is recommended to install a stable version of Wechaty published on NPM.com

```shell
npm install --save wechaty
```


If you use chrome instead of phantomjs, you should make sure:

1. chrome is installed
1. if you are under Linux, set headless right for `Xvfb`

* [Running a GUI application in a Docker container](https://linuxmeerkat.wordpress.com/2014/10/17/running-a-gui-application-in-a-docker-container/)

Then you are set.

## Install to Cloud9 IDE
[Cloud9 IDE](https://c9.io/) is Google Docs for Code, which is my favorite IDE today. Almost all my wechaty development is based on Cloud9.

> Cloud9 IDE written in JavaScript uses Node.js on the back-end. It uses Docker containers for its workspaces and hosted on Google Compute Engine.

### 1. Open in Cloud9 IDE

Just one click here: <a href="https://c9.io/open/?name=Wechaty&type=nodejs&clone_url=https://github.com/wechaty/wechaty.git&description=Wechat%20for%20Bot&selection_file=/example/ding-dong-bot.js" target="_blank"><img src="https://img.shields.io/badge/open%20in-Cloud9%20IDE-blue.svg" alt="Open Wechaty in Cloud9 IDE"></a>

### 2. Set default to Node.js v6
Open Terminal in Cloud9 IDE, use nvm to install nodejs v6, which is required by Wechaty.

```bash
$ nvm install 6
Downloading https://nodejs.org/dist/v6.2.1/node-v6.2.1-linux-x64.tar.xz...
######################################################################## 100.0%
Now using node v6.2.1 (npm v3.9.3)

$ nvm alias default 6
default -> 6 (-> v6.2.1)

$ node --version
v6.2.1
```

### 3. Run
```shell
$ npm install

$ npm run demo
```

### 4. Enjoy Cloud9 IDE
You are set.

## Install from Github
In case that you want to dive deeper into Wechaty, fork & clone to run Wechaty bot on your machine, and start hacking.

### 1. Install Node.js
Node.js Version 6.0 or above is required.

1. Visit [Node.js](https://nodejs.org)
1. Download NodeJS Installer(i.e. "v6.2.0 Current")
1. Run Installer to install NodeJS to your machine

### 2. Fork & Clone Wechaty

If you have no GitHub account, you can just clone it via https:
```shell
git clone https://github.com/wechaty/wechaty.git
```
This will clone wechaty source code to your current directory.

### 3. Run Demo Bot
```shell
cd wechaty
npm install
npm run demo
```

After a little while, bot will show you a message of an URL for Login QrCode. You need to scan this QR code in your wechat in order to permit your bot login.

### 4. Done

Enjoy hacking Wechaty!
Please submit your issue if you have any, and a fork & pull is very welcome for showing your idea.

# Trouble Shooting

If wechaty is not run as expected, run unit test maybe help to find some useful message.

```shell
$ npm test
```

To test with full log messages

```shell
$ WECHATY_LOG=silly npm test
```

[Details about unit testing](https://github.com/wechaty/wechaty/tree/master/test)

## LOG output
Wechaty use [npmlog](https://www.npmjs.com/package/npmlog) to output log message. You can set log level by environment variable `WECHATY_LOG` to show log message.

the environment variable `WECHATY_LOG` values:

1. `silly`
1. `verbose`
1. `info`
1. `warn`
1. `error`
1. `silent` for disable logging

Linux/Darwin(OSX/Mac):

```bash
$ export WECHATY_LOG=verbose
```

Win32:

```bat
set WECHATY_LOG=verbose
```

Tips: You may want to have more scroll buffer size in your CMD window in windows.

```bat
mode con lines=32766
```
> http://stackoverflow.com/a/8775884/1123955

### NpmLog with Timestamp ###
Here's a quick and dirty patch, to npmlog/log.js

```typescript
  m.message.split(/\r?\n/).forEach(function (line) {

    var date = new Date();
    var min = date.getMinutes()
    var sec = date.getSeconds()
    var hour = date.getHours()

    if (sec < 10) { sec = '0' + sec }
    if (min < 10) { min = '0' + min }
    if (hour < 10) { hour = '0' + hour }

    this.write(hour + ':' + min + ':' + sec + ' ')

    if (this.heading) {
      this.write(this.heading, this.headingStyle)
      this.write(' ')
    }
```

And we can look forward the official support from npmlog: https://github.com/npm/npmlog/pull/24

## DEBUG

set environment variable WECHATY_DEBUG to enable DEBUG in Wechaty.

this will:
1. open phantomjs debugger port on 8080

# Requirement

ECMAScript2015(ES6). I develop and test wechaty with Node.js v6.0.

# API Reference

I'll try my best to keep the API as simple as it can be.

## Events

Wechaty supports the following 6 events:

1. scan
2. login
3. logout
4. message
5. error
6. friend
7. room-join
8. room-leave
9. room-topic

### this.say(content: string)

`this.say()` method will sending message to `filehelper`, just for logging / reporting / any usage for your convenience

### 1. Event: `scan`

A `scan` event will be emitted when the bot needs to show you a QR Code for scanning.

```typescript
wechaty.on('scan', (this: Sayable, url: string, code: number) => {
  console.log(`[${code}] Scan ${url} to login.` )
})
```

1. URL: {String} the QR code image URL
2. code: {Number} the scan status code. some known status of the code list here is:
    1. 0    initial
    1. 200  login confirmed
    1. 201  scaned, wait for confirm
    1. 408  waits for scan

`scan` event will be emitted when it will detect a new code status change.

### 2. Event: `login`

After the bot login full successful, the event `login` will be emitted, with a [Contact](#class-contact) of current logined user.
```typescript
wechaty.on('login', (this: Sayable, user: Contact) => {
  console.log(`user ${user} login`)
})
```

### 3. Event: `logout`

`logout` will be emitted when bot detected logout, with a [Contact](#class-contact) of the current login user.

The `message` here is a [Message](#class-message).


### 6. Event: `friend`

Fired when we got new friend request, or confirm a friendship.

1. if `request?: FriendRequest` is set, then it's a friend request
1. if `request?: FriendRequest` is not set, then it's a friend confirmation

```ts
wechaty.on('friend', (this: Sayable, contact: Contact, request?: FriendRequest) => {
  if (request) {  // 1. request to be friend from new contact
    request.accept()
    console.log('auto accepted for ' + contact + ' with message: ' + request.hello)

  console.log(`Room ${room} got new member ${nameList}, invited by ${inviter}`)
})
```

### 8. Event: `room-leave`

```typescript
wechaty.on('room-leave', (this: Sayable, room: Room, leaverList: Contact[]) => {
  const nameList = leaverList.map(c => c.name()).join(',')

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.
