# Getting Started with Create React App
This project was bootstrapped with [Create React App](https://github.com/facebook/create-react-app).
## Available Scripts
In the project directory, you can run:
### `npm start`
Runs the app in the development mode.\
Open [http://localhost:3000](http://localhost:3000) to view it in your browser.
The page will reload when you make changes.\
You may also see any lint errors in the console.
### `npm test`
Launches the test runner in the interactive watch mode.\
See the section about [running tests](https://facebook.github.io/create-react-app/docs/running-tests) for more information.
### `npm run build`
Builds the app for production to the `build` folder.\
It correctly bundles React in production mode and optimizes the build for the best performance.
The build is minified and the filenames include the hashes.\
Your app is ready to be deployed!
See the section about [deployment](https://facebook.github.io/create-react-app/docs/deployment) for more information.
### `npm run eject`
**Note: this is a one-way operation. Once you `eject`, you can't go back!**
If you aren't satisfied with the build tool and configuration choices, you can `eject` at any time. This command will remove the single build dependency from your project.
Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except `eject` will still work, but they will point to the copied scripts so you can tweak them. At this point you're on your own.
You don't have to ever use `eject`. The curated feature set is suitable for small and middle deployments, and you shouldn't feel obligated to use this feature. However we understand that this tool wouldn't be useful if you couldn't customize it when you are ready for it.
## Learn More
You can learn more in the [Create React App documentation](https://facebook.github.io/create-react-app/docs/getting-started).
To learn React, check out the [React documentation](https://reactjs.org/).

1、react-router-dom
2、BrowserRouter HashRouter 标签
3、路由组件与一般组件的区别
4、Route标签 路由组件
5、NavLink标签 高亮效果
6、activeClassName 自定义高亮路由类名
7、批量接收props {...this.props}
8、children相当于标签体内容
9、Switch to只匹配path一次，可以提高效率
<NavLink to='/home'>编程式路由</NavLink>
<Route path="/home" component={Home}/>
<Route path="/home" component={Test1}/>
此时 to同时匹配 home和test1路由组件 使用Switch标签后只匹配第一个
10、exact属性严格匹配 to匹配path 按需使用，一般不用开启
<Route exact={true} path="/test" component={Test}/> to='/test/a/b' 此时to不能匹配path
<Route exact={false} path="/test" component={Test}/> to='/test/a/b' 此时可以匹配path
11、Redict重定向 兜底
12、路由嵌套
13、路由传参 pathname
14、push与replace
15、witchRoute 使一般组件拥有路由组件的属性，返回值是一个新组件
16、编程式路由
this.props.push()
this.props.replace()
