WECHATY v0.18: REDUCE WEIGHT

The only purpose for Wechaty v0.18 is to: Reduce Weight!

But, why do we need to reduce weight?

Let's back to May 2016, when the first version of Wechaty was published, it only contains thousands of lines of the code, and at the end of the year 2016, we have about 10,000 lines of the code. (you can read our blog at this time)

As the time passed by in 2017 & 2018, we added more features to Wechaty, like send attachment files, support WeChat protocol other than web like ipad, which means we write more and more codes in Wechaty repository... at last we get almost 30,000 lines of the code, and to be precise: 27,630. (with 377 unit tests, you can check it out at here if you are interested)

Is that fat? 30,000 lines of the code, is not too much, but it is not a small number too. After we finished abstracting the puppet base class after v0.16, it seems we have very good reason to begin reducing weight:

1. Abstract Puppet Class need to be imported by every puppet implementations, and it should to be a solo npm module, with good version management.
2. Every Puppet Implentation Class is better to be a solo npm module, becasue we can only install the required source code that we needed.

So at this version (v0.18), we have the follow npm modules that splited out from Wechaty:

WECHATY PUPPET LIST

1. For Puppet User

Stage	Name	Wechaty Puppet	Backend	Version
Release	puppeteer	PuppetPuppeteer	Web API via Browser Hooking
Beta	padchat	PuppetPadchat	iPad Protocol
Alpha	wechat4u	PuppetWechat4u	Web API via HTTP
Alpha	ioscat	PuppetIoscat (WIP)	iPhone App Hooking
TBW	Android		Android Hook	0.0.0
TBW	Win32		Win32 Hook	0.0.0

2. For Puppet Builder

Stage	Name	Wechaty Puppet	Backend	Version
Release	N/A	Puppet	Abstract Base Class
Release	mock	PuppetMock	Mocking

If we count the other npm modules that split out from Wechaty before, we can also list them as the following:

1. cloneClass: Clone an ES6 Class as Another Class Name for Isolating Class Static Properties.
2. hotImport: Hot Module Replacement(HMR) for Node.js
3. Brolog: Brolog is Logger for Angular in Browser like Npmlog.
4. FileBox: Pack a File into Box for easy move/transfer between servers no matter of where it is.(local, remote url, or cloud storage)
5. MemoryCard: Memory Card is an Easy to Use Key/Value Store Implements ES6 Map with Async API, with Swagger & Serialization Support.
6. RxQueue: Easy to Use RxJS Queue for Throttle/Debounce/Delay/DelayExecute
7. StateSwitch: State Switch is a Monitor/Guard for Managing Your Async Operations.
8. Watchdog: An Timer used to Detect and Recover from Malfunctions

Hmm... lots of them aha? So how can we keep all of them in one repository and manage them easily? It must be a nightmare!

So at last, as we published the v0.18, we only left 5,465 source lines of the code in Wechaty repository(11,006 physical lines). We can see a timeline from the history:

Source Lines of Code for Wechaty

From 27,630 to 11,006, we almost get the half size than before, cheers!
