react-router-dom

1、安装

yarn add react-router-dom

2、基本使用

BrowserRouter,HashRouter是两种路由方式，使用NavLink ,Link,Route时必须被路由器包裹。
NavLink ,Link是设置页面跳转，而NavLink有activeClassName属性，可以自定义设置active选中的class，默认activeClassName="active"。

import { BrowserRouter,HashRouter,NavLink ,Link,Route} from "react-router-dom"
import Home from './components/Home'
import About from './components/About'


<BrowserRouter>
  <NavLink activeClassName="demo" className="list-group-item" to="/about">
    About
  </NavLink>
  <NavLink activeClassName="demo" className="list-group-item" to="/home">
    Home
  </NavLink>
  <Route path="/about" component={About}></Route>
  <Route path="/home" component={Home}></Route>
</BrowserRouter>
