react-native-xnavigation

0.0.14 • Public • Published

介绍

本库基于React Navigation进一步封装的拦截器功能，让你轻松的在起始页跟目标页插入登录等多个拦截器。

实现思路参考博客

环境

环境要求

React Native >= 0.63.0
React Navigaion 6.x

安装

安装本库

npm install react-native-xnavigation

本库依赖了如下库

  "dependencies": {
    "@react-navigation/bottom-tabs": "6.0.9",
    "@react-navigation/native": "^6.0.6",
    "@react-navigation/stack": "^6.1.1",
    "react-native-safe-area-context": "^3.3.2",
    "react-native-screens": "^3.10.1",
    "react-native-gesture-handler": "^2.2.0",
  },

iOS、Android需要link react-native-screens、react-native-safe-area-context、 react-native-gesture-handler 这三个库

Hello React XNavigation

第一步：配置路由表

import * as React from 'react';
import { View, Text } from 'react-native';

function Home(){
  return (
    <View style={{ flex: 1, alignItems: 'center', justifyContent: 'center' }}>
      <Text>Home Screen</Text>
    </View>
  );
}

const routeConfig = {
  "/": {
    component: Home
  }
}

第二步：使用路由表

新建或修改app.js，路由表用来配置你的页面

import * as React from 'react';
import { View, Text } from 'react-native';
import { XNavigationContainer, XNavigator } from 'react-native-xnavigation';


const routeConfig = {
  "/": {
    component: Home
  }
}

function App() {
  return (
    <XNavigationContainer>
      <XNavigator initialRouteName="/" routerConfig={routerConfig}>
      </XNavigator>
    </XNavigationContainer>
  );
}

export default App;

initialRouteName为第一个显示的路由

使用app.js

import React from 'react';
import {
  AppRegistry
} from 'react-native';
import App from './app';

AppRegistry.registerComponent(
  'MyReactNativeApp', //注册模块，写成你自己的
  () => App
);

页面跳转

修改路由表，增加Detail详情页面


function Home(){
  return (
    <View style={{ flex: 1, alignItems: 'center', justifyContent: 'center' }}>
      <Text>Home Screen</Text>
    </View>
  );
}

function Detail(){
  return (
    <View style={{ flex: 1, alignItems: 'center', justifyContent: 'center' }}>
      <Text>Detail Screen</Text>
    </View>
  );
}

const routeConfig = {
  "/": {
    component: Home
  },
  "/detail": {
    component: Detail
  }
}

修改Home页面，导入router

import { router } from 'react-native-xnavigation';
function Home(){
  return (
    <View style={{ flex: 1, alignItems: 'center', justifyContent: 'center' }}>
      <Button title="跳转详情" onPress={() => {
        router.push('/detail')
      }}/>
    </View>
  );
}

页面传值

push的第二位参数传入参数

router.push('/detail', {code: 1000})

Detail页面接收参数

function Detail({ route }){
  const { code } = route.params;
  return (
    <View style={{ flex: 1, alignItems: 'center', justifyContent: 'center' }}>
      <Text>Detail Screen</Text>
      <Text>{code}</Text>
    </View>
  );
}

添加拦截器

修改路由表

import { router } from 'react-native-xnavigation';

class LoginInterceptor {
  intercept() {
    if(已登录){
      router.interceptNext();
    }else {
      router.push('/login');
    }
  }
}

function Login(){
  return (
    <View style={{ flex: 1, alignItems: 'center', justifyContent: 'center' }}>
      <Button title="登录" onPress={() => {
        router.interceptNext();
      }}/>
    </View>
  );
}

const routeConfig = {
  "/": {
    component: Home
  },
  "/detail": {
    interceptors:[
      {
        clazz: LoginInterceptor
      }
    ]
    component: Detail
  },
  "/login": {
    component: Login
  },
}

router.interceptNext()是告诉路由进行下一个拦截，如果没有拦截器的话，会直接进入目标页面，路由表interceptors支持多个拦截器，如下所示

class BindCardInterceptor {
  intercept() {
    if(已绑卡){
      router.interceptNext();
    }else {
      router.push('');
    }
  }
}

function BindCard(){
  return (
    <View style={{ flex: 1, alignItems: 'center', justifyContent: 'center' }}>
      <Button title="绑卡成功" onPress={() => {
        router.interceptNext();
      }}/>
    </View>
  );
}

const routeConfig = {
  "/detail": {
    interceptors:[
      {
        clazz: LoginInterceptor
      },
      {
        clazz: BindCardInterceptor
      }]
    component: Detail
  },
  "/bind-card":{ 
    component: BindCard
  }
}

路由表层级结构

路由表支持层级结构如下所示

const routeConfig = {
  "/my": {
    //申明嵌套路由
    subRoutes: { 
      "/bind-card": {
        component: BankCard //绑卡页面
      },
      "/record": {
        component: Record // 订单记录页面
      }
    }
  }
}

所以绑卡页面路由为/my/bind-card，订单记录路由为/my/record

底部Tabs

路由表配置

  "/": {
    tabs: {
      "/": {
        component: Home,
        options: {
          title: "首页",
          tabBarIcon: ({ focused }) => {
            return <Image style={{height: 21, width: 21}} source={focused ? require('./images/a_focus.png') : require('./images/a.png')}/>
          }
        },
      },
      "/my": {
        component: My,
        options: {
          title: "我的",
          tabBarIcon: ({ focused }) => {
          return <Image style={{height: 21, width: 21}} source={focused ? require('./images/b_focus.png') : require('./images/b.png')}/>
          }
        },
      },
    }
  },
