Subject [Incubator Wiki] Update of "Weex" by BonoLv
Date Wed, 09 Nov 2016 03:12:54 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Incubator Wiki" for change notification.

The "Weex" page has been changed by BonoLv:

New page:
= Weex Proposal =

== Abstract ==
Weex is a framework for building Mobile cross-platform UI.

== Proposal ==
Weex allows developers to build iOS,Android and Web user interface with a single codebase.
Compared with WebView based UI framework which performance and features are limited, Weex
preserves its lightweight development pattern and improve the user experience by high-quality
native view and native features at the same time.. 

Weex provide a tag based language which maintained a consistent style with Web standards.
 Developers write in this language just like writting in HTML. After transforming to JSBundle
by Weex build-in tools, these tag will be render to higher-level platform-specific components
using Weex SDK.

Because Weex use JavaScript as UI operation and data processing language which don't need
compile before execute in user's Mobile phone. Interface implemented by Weex is "Dynamic".
At the time of this writing , another famed dynamic Native UI framework is React Native which
developed by Facebook Inc .

Weex and React Native share some common features but have different language syntax. React
Native use specific JSX , whereas Weex use vanilla Javascript .React Native set target that
to replace whole Mobile App development process, whereas Weex allow developer choose which
page in Mobile App should be implemented by Weex freely. At principle level React Native adopt
"Learn Once, Write Anywhere", whereas Weex keep "Write Once, Run Everywhere" on different
platform development environment.

We think Weex is an effective supplement to Apache Cordova. Both Apache Cordova and Weex help
developer for leveraging Web development technique in Mobile age. Boot developer the ability
of delivering consistent content to different platform. With our sincere heart and determination
to open source , we will always keep an open mind for Apache Cordova community.

== Background ==
Prior to Weex, in order to develop high performance mobile application we need write at least
three different codebase(iOS,Android,Mobile Web) or adopt WebView based UI technique(Apache
Cordova for example) which can't satisfy the demand for neat user experience on critical Interactive

A special task force at Alibaba Inc try to provide a solution for this problem have been setup
since 2013.  At first the team release an cross-platform rendering engine which render a special
format JSON to native components on different platform. To output this JSON file the team
had  build a website which other developer can use to simply design final interface.

This solution had worked for a while. We found it not able to meet our requirement , the website
be use to design interface have too many limitations , the JSON file be use to render final
interface lacks enough dynamics. The following discussion inspire we start to develop Weex.

Now days, Mobile Taobao App which developed by Alibaba Inc , the largest user volume eCommerce
App in China have adapted Weex in a lot of UI. We have measured Weex page and prior Mobile
Web page which have same interface design and content with Weex page by A/B testing in one
of Mobile Taobao shopping guide product. The result show the Bounce Rate drop from 5.5%(Mobile
Web page) to 1.7%(Weex page).

== Current Status ==
Weex have become a open source project since June 2016.  It have been use at a lot of Alibaba
producted mobile softwares which running on the mobile phone of millions of users.

Weex code repository located at GitHub . All development activities have already happened
on GitHub as open source manner.

== Community ==
The community surrounding Weex is a variety of developer which have different technique background.
iOS,Android,Web developer must collaborate closely to implement most Weex feature.  

Currently total 43 contributors involved in the GitHub development process. Weex repository
have received 517 pull requests until Aug 2016.

Beyond committer from Alibaba Inc,Weex community welcome anybody join us.Now days Evan You
from Vue Technology LLC, Wang Run Xiang from Aipai Inc and lots of GitHub users have contributed
source code or document to Weex.

At the time of this writing ( Aug 2016) Weex GitHub star number is 4935 , watch number is
1829 , fork number is 500.  
Weex use GitHub issue for problem tracking and technical discussion.  Currently 437 issues
have been submited , 362 of them have been solved.

== Core Developer ==
 * BryantWu
 * LuicsXu   (iOS)
 * Jin-JiangZhao  (Web/Node)
 * Tai-ChengHuang (Web/Node)
 * FengYin    (iOS)
 * YuanYin      (Android)
 * BobNing       ningli928@1 6    (iOS)
 * WeiZheng  (Android)
 * YorkShen (Android)
 * SaiHe    (Web)
 * BonoLv     (Web/Node)
 * GurisXie     (Testing)
 * AtomTong  (Testing)

== Known Risks ==
"Write Once Run Everywhere"  is one of original goal of Weex.  But as Weex  provides more
feature ,we have received more suggestions for implement single platform exclusive feature.

== Source Code ==
 * Main repository:
 * Weex transformer:
 * Weex toolkit:
 * Weex loader:
 * Gulp Weex:

== Documentation ==
 * English Document:
 * Chinese Document(English first , currently only partially doc have been translate to Chinese):中文文档

== Next Goals ==
 * License all Weex source code and documentation to the Apache Software Foundation. ( We
already using Apache license for our main code repository) 
 * Setup and standardize the open governance of the Weex Project.
 * Move Weex development activity to Apache infrastructure ( Git repository , Mail list )
