# Febs React Web


> A framework for building web apps with React Native compatible API.

> 在 [React-web@0.3.2](http://github.com/taobaofed/react-web) 的基础上编写.

> Febs React Web 项目兼容react-native, 能够以react-native方式编写项目, 并且最终导出html/js方式. 基于reactjs, 构建单页/多页webapp.

## Create a new project

1. Install `npm install febs-react-web-cli -g`
2. Execute `febs-react-web init <ProjectDir>`.
3. Execute `febs-react-web start` that starts the web dev server
4. Execute `febs-react-web bundle` that builds the output.

    ( In Linux system maybe use `sudo` )


## Fix platform differences

1. Native events without direct pageX/pageY on web platform
  ```js
  if (Platform.OS == 'web') {
    var touch = event.nativeEvent.changedTouches[0];
    pageX = touch.pageX;
    pageY = touch.pageY;
  } else {
    startX = event.nativeEvent.pageX;
    startY = event.nativeEvent.pageY;
  }
  ```

2. Should run application on web platform
  ```js
  AppRegistry.registerComponent('app', () => app);
  if(Platform.OS == 'web'){
    var app = document.createElement('div');
    document.body.appendChild(app);
    AppRegistry.runApplication('app', {
      rootTag: app
    })
  }
  ```

3. Should care about fetch domain on web platform
  ```js
  import {
    Fetch,
    Jsonp
  } from 'react-native'
  ```
  Jsonp 只支持jsonp格式: callback({json}), 且只能是get方式.
  Fetch 使用XMLHttpRequest, 需处理跨域问题.


4. Without some APIs like `LayoutAnimation` on web platform
  ```js
  var LayoutAnimation = require('ReactLayoutAnimation')
  if(Platform.OS !== 'web'){
    LayoutAnimation.configureNext(...)
  }
  ```

5. Should manually specify the height of ScrollView
  ```js
  <ScrollView style={{height: 235}} horizontal={true} />
  ```
