react-router v6嵌套路由简单案例

​
react-router V6版本路由用法和V5用法差距较大,一个简单的使用案例

新版本组件也开始使用函数式组件+hooks

"react-router-dom": "^6.2.1",

1.入口main 

import "./App.css";
import { BrowserRouter, Route, Routes, Navigate } from "react-router-dom";
import Index from "./modules/index/Index";
import Error from "./modules/error/Index";
import Admin from "./modules/admin/Index";

const App = () => {
    return (
        

            {/* HashRouter哈希路由 还是 Browser路由随需求选择 */}
            
                
                    {/* 默认初始化入口/home*/}
                    } />
                    {/* home模块路由 */}
                    } />
                    {/* admin模块路由 */}
                    } />
                    {/* 404页面 */}
                    } />
                
            
        
    );
};

export default App;

2.子路由-Index模块(案例举例)

import { Route, Routes } from "react-router-dom";
import MainIndex from "./page/index/Index";
import Nav from "./page/nav/Nav";

import Error from "../error/Index";


const Index = () => {
    return (
        

            
                    {/* path="/"初始化默认 */}
                    } />
                    } />
                    {/* 子路由的404页面 */}
                    } />
                
        
    );
};
export default Index;

3.路由跳转方法2种 useNavigate, Link

import { useNavigate, Link } from "react-router-dom";

const Child = (props) => {
    const navigate = useNavigate();
    return (
        

            {/* link跳转 */}
            跳转路由
            

            
 {
                // 逻辑跳转
                navigate("/admin/componentDelivery");
                // replace 跳转
                // navigate('/home', {replace: true});
                // navigate("/");
                // 回退步数 0刷新页面
                // navigate(-1);
            }}>
           
        
    );
};
export default Child;
