2022~07~21,晴,闷热的不行,大早上下地铁就看到了一个身材巨好穿着超短裙的美女,心情美滋滋。废话不多说,上步骤:
1:桌面随便新建一个文件夹,用来存放项目,我的叫my-react
2:打开my-react文件夹,在路径中输入cmd,然后回车
3:然后输入命令:create-react-app project(你想起的项目名称)
4: 此时执行npm start就可以运行项目了,但是虽然项目已经运行成功,但是在项目目录里是找不到webpack
配置项的。比如,我们想配置less
、sass
、配置项目接口请求等,这时我们需要做一个操作:展开项目(eject
)
注意:这个一个不可逆过程,一旦执行了,就不能回到初始化 。
cd进入到project目录中、执行eject解压配置命令:npm run eject
再看项目结构,此时已多了一些其他目录,展开config目录,里面就有webpack配置文件以及其他各种配置
5:安装less配置
vue-cli 构建的项目默认是不支持 less 的,需要自己添加
运行命令:npm install less less-loader --save-dev
6:安装路由组件router:
npm install react-router-dom
7:添加状态管理mobx。
mobx是做状态管理的,mobx-react是做数据分片和数据获取
npm install mbox mbox-react。
npm install babel-plugin-transform-decorators-legacy
package.json
文件中的 babel
参数添加下面代码:
- "plugins": [
- [
- "@babel/plugin-proposal-decorators",
- {
- "legacy": true
- }
- ]
- ]
8:数据请求axois,安装axios库:
9:引入使用最多的react UI库ant design:npm instal antd
10:安装ts:npm install --save typescript @types/node @types/react @types/react-dom @types/jest
一切安装完毕,运行项目:npm start
---------------------------------------------------------分---隔---线-------------------------------------------------------
1:在src文件夹下新建api、components、pages、router文件夹
2:在pages新建login和index文件夹,分别新建login.js和index.js文件
index.js代码:
- import React, { Component } from "react";
- import { Layout, Switch, Menu } from "antd";
- // import { RenderRoutes } from "../../router/utils";
- import { Link } from "react-router-dom";
- // require("./index.less");
-
- const { Header, Content, Sider } = Layout;
- const { SubMenu } = Menu;
-
- class Index extends Component {
- state = {
- collapsed: false,
- theme: "dark",
- };
-
- onCollapse = (collapsed) => {
- console.log(collapsed);
- this.setState({ collapsed });
- };
- changeTheme = (value) => {
- this.setState({
- theme: value ? "dark" : "light",
- });
- };
- render() {
- const { collapsed } = this.state;
- let { routes } = this.props;
- console.log(routes);
- return (
- <Layout style={{ minHeight: "100vh" }}>
- <Sider
- theme={this.state.theme}
- collapsible
- collapsed={collapsed}
- onCollapse={this.onCollapse}
- >
- <div className="logo" />
- <Menu
- theme={this.state.theme}
- defaultSelectedKeys={["/user/experience"]}
- defaultOpenKeys={["sub1"]}
- mode="inline"
- >
- <Menu.Item key="1">
- <Link to="/user/WorkBench">工作台</Link>
- </Menu.Item>
- <SubMenu key="sub1" title="用户管理">
- <Menu.Item key="/user/experience">
- <Link to="/user/experience">体验用户</Link>
- </Menu.Item>
- <Menu.Item key="4">VIP用户</Menu.Item>
- <Menu.Item key="5">
- <Link to="/user/Details">用户详情</Link>
- </Menu.Item>
- </SubMenu>
- </Menu>
- </Sider>
- <Layout className="site-layout">
- <Header className="ant-layout-header" style={{ background: "#fff" }}>
-
- </Header>
- <Content style={{ margin: "16px 16px" }}>
- {/* <RenderRoutes routes={routes}></RenderRoutes> */}
- </Content>
- </Layout>
- </Layout>
- );
- }
- }
- export default Index;
login.js代码:
- import React, { Component } from "react";
- // require("./index.less");
- class Login extends Component {
- render() {
- return (
- <div className="main-page">
- 登录页
- </div>
- );
- }
- }
- export default Login ;
在这个步骤有可能会报如下错误,不要慌
原因:这些报错原因均为'Switch' 和'Redirect' 是react-router 5版本的接口,在项目中的package.json中查看你的react-router-dom版本,版本是"react-router-dom": "^6.x.x"。新版并且已经将Switch改为Routes。
解决办法有二:
1.将所有 Switch 改为 Routes,Redirect 改为 Navigate ,withRouter改为 useNavigate
(vscode中,按快捷键:CTRL+F及可查找替换)
2.卸载新版本,再安装5的版本
npm uninstall react-router-dom
npm install react-router-dom@5
我直接使用的第二个,卸载了新版本,重新装了5的版本,就没问题了
3:在router文件夹下新建router.js和allocation.js
router.js代码
- import Login from '../pages/login/login'
- import Index from '../pages/index/index'
- // 菜单相关路由
- export const menus = []
- //登录、首页、404路由
- export const main = [
- { path: '/login', exact: true, name: '登录', component: Login },
- { path: '/', name: '首页', component: Index, routes: menus },
- ]
-
- export const routerExport = {
- main, menus
- }
allocation.js代码:
- import React from 'react';
- import { Route, Link, Switch, Redirect } from "react-router-dom";
-
- export const SubRoutes = route => (<Route
- path={route.path}
- exact={route.exact}
- render={props =>{
- return (
- route &&( route.Redirect ? (<Redirect to={route.Redirect}></Redirect>) :
- (<route.component {...props} routes={route.routes} />))
- )
- }}
- />
- );
-
- export const RenderRoutes = ({routes}) => {return <Switch> {(routes.map((route, i) => <SubRoutes key={i} {...route} />))} </Switch> };
4:到app.js配置
app.js代码
- // import logo from './logo.svg';
- import './App.css';
- import 'antd/dist/antd.css'; // or 'antd/dist/antd.less'
- import { BrowserRouter as Router } from "react-router-dom";
- import { main as mainConfig } from "./router/router";
- import { RenderRoutes } from "./router/allocation";
-
- function App () {
- return (
- <Router>
- <div className="App">
- <RenderRoutes routes={mainConfig}></RenderRoutes>
- </div>
- </Router>
- );
- }
-
- export default App;
5:接下来输入http://localhost:3000/login和http://localhost:3000就能看到首页和登录页了
6:接着对index布局,采用antD的layout组件
index.js代码:
- import React, { Component } from "react";
- import { Layout, Switch, Menu } from "antd";
- // import { RenderRoutes } from "../../router/utils";
- import { Link } from "react-router-dom";
- // require("./index.less");
-
- const { Header, Content, Sider } = Layout;
- const { SubMenu } = Menu;
-
- class Index extends Component {
- state = {
- collapsed: false,
- theme: "dark",
- };
-
- onCollapse = (collapsed) => {
- console.log(collapsed);
- this.setState({ collapsed });
- };
- changeTheme = (value) => {
- this.setState({
- theme: value ? "dark" : "light",
- });
- };
- render() {
- const { collapsed } = this.state;
- let { routes } = this.props;
- console.log(routes);
- return (
- <Layout style={{ minHeight: "100vh" }}>
- <Sider
- theme={this.state.theme}
- collapsible
- collapsed={collapsed}
- onCollapse={this.onCollapse}
- >
- <div className="logo" />
- <Menu
- theme={this.state.theme}
- defaultSelectedKeys={["/user/experience"]}
- defaultOpenKeys={["sub1"]}
- mode="inline"
- >
- <Menu.Item key="1">
- <Link to="/user/WorkBench">工作台</Link>
- </Menu.Item>
- <SubMenu key="sub1" title="用户管理">
- <Menu.Item key="/user/experience">
- <Link to="/user/experience">体验用户</Link>
- </Menu.Item>
- <Menu.Item key="4">VIP用户</Menu.Item>
- <Menu.Item key="5">
- <Link to="/user/Details">用户详情</Link>
- </Menu.Item>
- </SubMenu>
- </Menu>
- </Sider>
- <Layout className="site-layout">
- <Header className="ant-layout-header" style={{ background: "#fff" }}>
-
- </Header>
- <Content style={{ margin: "16px 16px" }}>
- {/* <RenderRoutes routes={routes}></RenderRoutes> */}
- </Content>
- </Layout>
- </Layout>
- );
- }
- }
- export default Index;
接下来输http://localhost:3000就能看到首页了
