Implement a persistent data store manager ( based AsyncStorage )

   export const RNStorage = {// RNStorage : custom data store object
       token: null, // string type
       isShow: null, // bool type
       userInfo: null, // object type
   };

  import { XStorage } from 'react-native-easy-app';
  import { AsyncStorage } from 'react-native';
   
  XStorage.initStorage(RNStorage, AsyncStorage, () => {
      ... // RNStorage 【Property access code snippet】
  });
  
  // OR ---------------------------------------------------------------
  
  const result = await XStorage.initStorageSync(RNStorage, AsyncStorage);
  if (result) {
      ... // RNStorage 【Property access code snippet】
  }

 // RNStorage 【Property access code snippet】
 
 // From now on, you can write or read the variables in RNStorage synchronously
 
 console.log(RNStorage.isShow);
 // equal to [console.log(await AsyncStorage.getItem('isShow'))] 
  
 RNStorage.token = 'TOKEN1343DN23IDD3PJ2DBF3==';
 // equal to [ await AsyncStorage.setItem('token',TOKEN1343DN23IDD3PJ2DBF3==') ]  
 
 RNStorage.userInfo = {name: 'rufeng', age: 30};
 // equal to [ await AsyncStorage.setItem('userInfo',JSON.stringify({ name:'rufeng', age:30})) ]

Note: If the React Native version of the project is higher than 0.60, the parameters of storageImp, it is recommended to use the [AsyncStorage] instance in '@react-native-community/async-storage'

Configurable Http request framework

All based on configuration (configuration optional, free to set)

import { XHttpConfig, XHttpConst } from 'react-native-easy-app';

XHttpConfig().initLogOn(true)
             .initBaseUrl('https://www.baidu.com')

new HttpRequest() ==> XHttp()

It is recommended that it be more convenient to send requests using XHttp()

request-send

synchronous request

   import { XHttp } from 'react-native-easy-app';
   
   const url = 'https://www.google.com';
  
   const result = await XHttp().url(url).execute('GET');
   const {success, json, message, status, response} = result;
   
   if(success){
      this.setState({content: JSON.stringify(json)})
   } else {
      showToast(message)
   }

asynchronous request mode 1

   XHttp().url(url).get((success, json, message, status, response)=>{
       if (success){
          this.setState({content: JSON.stringify(json)});
       } else {
          showToast(msg);
       }
   });

asynchronous request mode 2

   XHttp().url(url).execute('GET').then(({success, json, message, status, response}) => {
       if (success) {
            this.setState({content: JSON.stringify(json)});
       } else {
            showToast(message);
       }
    })

Flexible base widget

   XView
   XImage
   XText
   
   XFlatList
   
   XWidget
   .initResource(AssetsBaseUrl)    // The uri prefix of the icon attribute of the XImage component
   .initReferenceScreen(375, 677); // The component scales the reference screen size

XView, XImage, and XText all contain the raw attribute. If the raw value is true, the setting of XWidget.initReferenceScreen (referenceWidth, referenceHeight) is ignored: multi-screen size adaptation is not automatically processed

XView Object

Property	type	Description
raw	bool	default:false, if true, the multi-screen adaptation function will be disabled.
...	...	If the onPress or onLongPress property is included, it has the same property as TouchableXXX, otherwise it has the same property as View

XImage Object

Property	type	Description
raw	bool	default:false, If true, the multi-screen adaptation function will be disabled.
icon	string	equivalent to Image's srouce attribute,Can accept such as [https://xxx.yy.com/../image.jpg], [data: image / png; base64, iVBORw0KGgoAAAAN ...] or [require ('./ image.jpg')]
iconSize	number	the size of the image has priority over the width and height of the style
...	...	if the onPress and onLongPress functions are set, XImage will be wrapped by XView, and the externally passed properties will be automatically assigned to the correct control

XText Object

Property	type	Description
raw	bool	default:false, If true, the multi-screen adaptation function will be disabled.
text	string	text
textExtend	bool	if the icon is included, it is equivalent to setting the property of the Text component: {flex: 1}
icon	string	equivalent to Image's srouce attribute,Can accept such as [https://xxx.yy.com/../image.jpg], [data: image / png; base64, iVBORw0KGgoAAAAN ...] or [require ('./ image.jpg')]
resizeMode	string	icon resizeMode
iconSize	number	icon size
iconStyle	object	icon style
iconMargin	number	distance between icon and text
iconPosition	string	the position of the icon in the View, only the following values can be set: 'top', 'right', 'bottom', 'left'
...	...	if the onPress and onLongPress functions are set, XText will be wrapped by XView, and the externally passed properties will be automatically assigned to the correct control

XFlatList Object

Property	type	Description
data	array	equivalent to data of FlatList control
refreshStatus	object	XFlatList list displays UI styles and text setting objects in different refresh states
indicatorProps	object	set the style and attributes of RefreshControl
onRefresh	() => {...}	equivalent to onRefresh of FlatList control
onLoadMore	() => {...}	When the list scrolls to the bottom, the callback method is executed (when more data needs to be loaded)
renderEmptyViewFunc	(status, isEmpty) => {...}	Customize the realization of EmptyView in various states
renderRooterViewFunc	(status, isEmpty) => {...}	Customize the implementation of RooterView in various states
...	...	all remaining properties of [FlatList] component

FlatList component refreshStatus attribute example

 const RefreshStatus = {
   Idle: {}, //idle status
 
   RefreshingData: {  text: 'Loading...' }, // Pull-down refresh..
   NoData: {  text: 'No data' }, // To drop down to refresh (no data).
   LoadFailure: {  text: 'Failed to load' }, // Drop-down refresh (load failed)
 
   LoadingMoreData: { moreText: 'Loading more data…' }, // Load more, in progress...
   NoMoreData: { moreText: 'No more data' }, // Load more (no data)
   LoadMoreFailure: { moreText: 'Click to reload' }, // Load more (load failed)
   
   NetException: {text: 'network exception', moreText: 'Network exception, click reload'}, // network exception
 }

Version log

1.7.0 XStorage initialization adds required parameter storageImp (AsyncStorage instance)
1.7.4 Set the default timeout of XHttpConfig to 15 seconds; update the readme file and add XStorage synchronization initialization code snippets.
1.7.5 Remove the parameter urlEncoded processing of specific request, only support global encoding or no encoding; fix the encoding processing under non-formEncoded type.
1.7.6 Set the default contentType of XHttpConfig to application/x-www-form-urlencoded; set the default icon of XText to be at the top of the text.
1.7.7 XText adds iconStyle and resizeMode attributes; XHttp common parameters add support for incoming FormData, the original parameter paramRaw supports sending the request directly without processing.
1.7.8 Fix the bug that XImage does not support tintColor style when there is a click event.
1.7.9 XFlatList adds ref attribute: ref => this.flatList = ref, so that XFlatList can support the related methods owned by FlatList, the usage is as follows: this.refreshList.flatList.scrollToOffset({...}).
1.7.12 When the request is successful, the meaningless timeout timer is cleared in time to reduce unnecessary waste of timer resources.
1.7.13 XFlatList adds attributes renderFooter, indicatorProps to control its style and attributes more flexibly.
1.7.16 XFlatList adds attributes such as indicatorProps, renderEmptyViewFunc, renderRooterViewFunc, etc., which can customize the layout of indicator, emptyView in various states and rooterView
1.7.17 XFlatList adds attribute renderPreEmptyViewFunc, which is used to customize the layout of EmptyView when the list is not loaded with any data.
1.7.18 HttpConfig adds the initNetworkExceptionFunc method, through the @react-native-community/netinfo instance object specified by the user, the corresponding callback processing is done according to the current network status when requesting
1.7.19 XFlatList merges renderPreEmptyViewFunc into renderEmptyViewFunc method, removes XText’s default support for allowFontScaling
1.7.20 Fix the bug that the judgment condition of the screen adaptation method validReferSize is wrong
1.7.23 Removed unnecessary data type conversion implementation when XStorage reads data from persistence to memory
1.7.25 Compatible XStorage data storage can not effectively handle the bug of undefined type data (an exception will be reported on IOS)
1.7.26 Rename the XHttpConfig method initHttpLogOn to initLogOn, rename the XFlatList method renderRooterViewFunc to renderFooterViewFunc, modify the readme document description
