Quick Start

<Router ref="router" 
        renderTitle={(route)=> {
            return <Text style={{color: "white"}}>{route.title}</Text>;
        }}  
        renderLeftButton={(route, navigator, index)=> {
            if (index > 0) {
                return <Text style={{color: "white"}} onPress={event=> {
                    navigator.$pop();
                }}>back</Text>
            }
            return null;
        }}
        navigationBarStyle={{backgroundColor: "black"}}
        routes={[{
            path: "home",
            title: "Home",
            component: Home
        }, {
            path: "register",
            title: "Register-Step1",
            component: RegisterStep1,
            routes: [{
                path: "step2",
                title: "Register-Step2",
                hideNavigationBar: true,
                component: RegisterStep2
            }]
        }]}>
</Router>

Router Props

renderTitle(route:route,navigator:NavigatorEx,index:number,navState:route[])

Set title for navigation. the default value will return a text node:

<Text>{route.title}</Text>

renderLeftButton(route:route,navigator:NavigatorEx,index:number,navState:route[])

Set back button or left button for navigation, null as default value.

navigationBarStyle

Set navigation style

routes

The first route as initial route

type route

• path:string route path that is required.
• title:string navigation title
• renderLeftButton(route:route,navigator:NavigatorEx,index:number,navState:route[]):function set left button for navigation. if it is provided , the Router.renderLeftButton will be ignore.
• renderRightButton(route:route,navigator:NavigatorEx,index:number,navState:route[]):function set right button for navigation.
• renderTitle(route:route,navigator:NavigatorEx,index:number,navState:route[]):function if it is provided , the Router.renderTitle will be ignored.
• hideNavigationBar:boolean [hideNavigationBar=false] whether hide navigation.
• routes:route[] this is required.
• component:Component
• onEnter(route:route):function invoke when navigator.$push,you can return a available path to redirect or nothing. NOTE1:if you return a available path in here , you can access route.$previousRoute and route.$previousPath in new path. NOTE2:don't be invoked when start app from initial route.

configureScene()

configure page transition, you can refer to React Native Navigator the default value is Navigator.SceneConfigs.HorizontalSwipeJump.

onChange(type:string,route:route,path:string)

Invoke when navigator $push,$pop,$replace,$refreshNavBar

navigator methods

$push(path:string[,route:route])

router will push to target path.the parameter route will override route which find by path.

//go to 'register'
this.props.navigator.$push("register")
//go to 'register/register-step2' 
this.props.navigator.$push("register/register-step2");
//override route which find by path with the second parameter
this.props.navigator.$push("register",{
	title:"Register"
});

in addition you can pass props through the second parameter.

this.props.navigator.$push("register",{
	tel:"13100000000"
})

$pop()

back to previous route.

$replace(path:string[,route:route])

replace current route with path. the second parameter is the same as $push

$refreshNavBar([route:route])

Refresh navigation's style.

this.props.navigator.$refreshNavBar({
    title:"test",
    renderLeftButton:()=>{},
    renderRightButton:()=>{}
})

NOTE:this method must't be calling in component's lifecycle, such as componentDidMount,only calling in sceneDidFocussceneDidFocus.

Router event

sceneDidFocus(route)

Refer to Navigator.onDidFocus

class TestComponent extends Component{
	sceneDidFocus(){
		//do something
	}
}

sceneWillFocus(route)

Refer to Navigator.onWillFocus

class TestComponent extends Component{
	sceneWillFocus(){
		//do something
	}
}

Authentication

Example

const routes = [{
	path: "home",
	title: "Home",
	component: Home
}, {
	path: "register",
	title: "Register-Step1",
	component: RegisterStep1,
	routes: [{
		path: "step2",
		title: "Register-Step2",
		hideNavigationBar: true,
		component: RegisterStep2
	}]
},{
	path: "login",
	title: "Login",
	component: Login
}, {
	path: "mine",
	title: "Mine",
	component: Mine,
	onEnter: ()=> {
		if (!isLogin) {
			return "login";
		}
	}
}];

after login success.

this.props.navigator.$replace(this.props.route.$previousPath);

or

this.props.navigator.$pop();

Async Authentication

More time we determine login state with token , but we can't get token value in sync , so we need a page to initial some data , such as token . after we can use these data in sync. when you need to restore redux , the step is useful. sample code following:

window.appData={
	token:""
};

class Init extends Component{
	
	componentDidMount(){
		getToken().then(value=>{
			if(value){
			    window.appData.token=value;
			    this.props.navigator.$replace("home");
			}
			else{
				this.props.navigator.$replace("login");
			}
		})
	}
	
}

you can get current net state or anything data in here except above.

How to use Router with Redux

import Router from "mkp-react-native-router";
import {connect, Provider} from "react-redux";

const RouterWithRedux = connect()(Router);

<Provider store={store}>
        <RouterWithRedux
            navigationBarStyle={navigationStyles.navigationBar}
            renderTitle={(route)=> {
                return (
                    <View style={[navigationStyles.base]}>
                        <Text style={[navigationStyles.title]}>{route.title}</Text>
                    </View>
                );
            }}
            renderLeftButton={(route, navigator, index)=> {
                if (index > 0) {
                    return (
                        <TouchableHighlight
                            style={[navigationStyles.base, navigationStyles.leftButton]}
                            onPress={event=> {
                                navigator.$pop();
                            }}>
                            <Image source={require("./themes/assets/icons/back-icon.png")}/>
                        </TouchableHighlight >
                    );
                }
                return null;
            }}
            routes={routes}></RouterWithRedux>
</Provider>

you can deal with some action that is 'SCENE_WILL_FOCUS' and 'SCENE_DID_FOCUS' in reducer. example following,

import {ActionTypes} from "mkp-react-native-router";
export function testReducer(state,action){
    switch(action.type){
        case ActionTypes.SCENE_WILL_FOCUS:
            //you can access the route from action.route
            //do something
            break;
        case ActionTypes.SCENE_DID_FOCUS:
            //you can access the route from action.route
            //do something
            break;
        default:
            return state;
    }
}

How to deal with hardware back event on android

Router provide two property currentRoute and navigator, you can do something through these property. following code:

class Test extends Component{
    constructor(props){
        super(props);
        BackAndroid.addEventListener("hardwareBackPress",()=>{
            // if router with redux
            //let cur=this.refs.router.renderedElement._owner._renderedComponent._instance.currentRoute;
            //let navigator=this.refs.router.renderedElement._owner._renderedComponent._instance.navigator;
            //else
            //let cur=this.refs.router.currentRoute;
            //let navigator=this.refs.router.navigator;
            let cur=this.refs.router.renderedElement._owner._renderedComponent._instance.currentRoute;
            let navigator=this.refs.router.renderedElement._owner._renderedComponent._instance.navigator;
            if(cur.path==="login" || cur.path==="home"){
                //exit
                confirm("确定要关闭应用吗?",ok=>{
                    if(ok){
                        BackAndroid.exitApp();
                    }
                })
            }
            else{
                navigator.$pop();
            }
            return true;
        });
    }
    render(){
        return (
            <Router ref="router"></Router>
        )
    }
}
