react 项目搭建
系统: windows
1. 安装 node
node 下载地址. 一路 next
如果遇到 windows 没有权限安装 msi 文件. 打开 cmd, 运行 msiexec /package 文件路径.
查看是否安装成功, 打开终端
node -v
npm -v
2. 安装 vscode 编辑器
vscode 下载地址. 一路 next
3. 安装 react 项目脚手架
打开终端
npm install -g create-react-app
4. 创建 react 项目
create-react-app myApp
cd myApp
npm install
npm start
code .
5. 安装项目依赖
npm i react-router-dom mobx mobx-react axios qs –save
配置装饰器语法支持
npm i –save-dev @babel/plugin-proposal-class-properties @babel/plugin-proposal-decorators
解压 webpack 配置
npm run eject
修改 webpack.config.dev.js 和 webpack.config.prod.js
{
test: /\.(js|mjs|jsx|ts|tsx)$/,
include: paths.appSrc,
loader: require.resolve(‘babel-loader’),
options: {
customize: require.resolve(‘babel-preset-react-app/webpack-overrides’),
plugins: [
+ [‘@babel/plugin-proposal-decorators’, { legacy: true}],
+ [‘@babel/plugin-proposal-class-properties’, { loose: true}],
[
require.resolve(‘babel-plugin-named-asset-import’),
{
loaderMap: {
svg: {
ReactComponent: ‘@svgr/webpack?-prettier,-svgo![path]’
}
}
}
]
],
// This is a feature of `babel-loader` for webpack (not Babel itself).
// It enables caching results in ./node_modules/.cache/babel-loader/
// directory for faster rebuilds.
cacheDirectory: true,
// Don’t waste time on Gzipping the cache
cacheCompression: false
}
}
6. 配置路由
在项目中新建 src\pages 文件夹. 新建页面文件 src\pages\Home\index.js
// Home\index.js
/**
* @name Home
* @desc 首页
*/
import React, {Component} from ‘react’
class Home extends Component {
render() {
return (
<div>
<h1>Home</h1>
</div>
)
}
}
export default Home
新建 router.js
/**
* @name Router
* @desc 页面路由配置
*/
import React, {Component} from ‘react’
import {Switch, Route, Redirect} from ‘react-router-dom’
import Home from ‘./pages/Home’
class Router extends Component {
render() {
return (
<Switch>
<Redirect path=”/” to=”/home” exact />
<Route path=”/home” component={Home} />
</Switch>
)
}
}
export default Router
7. 配置 http 请求插件
新建 src\utils\axios.js
import axios from ‘axios’
import qs from ‘qs’
const axiosIns = axios.create({
baseURL: ‘/’,
timeout: 10000,
responseType: ‘json’,
transformRequest: [data => qs.stringify(data)],
headers: {
‘Content-Type’: ‘application/x-www-form-urlencoded;charset=utf-8’
}
})
axiosIns.interceptors.request.use(
config => {
return config
},
error => Promise.reject(error)
)
axiosIns.interceptors.response.use(result => result.data, error => Promise.reject(error))
const get = (url, params = null, config = {}) => axiosIns.get(url, { …config, params})
const post = axiosIns.post
const all = axiosIns.all
export {get, post, all}
8. 配置状态管理插件
8.1 新建 src\utils\mobx-store.js
/**
* @name Store
* @desc store 构造器
*/
import {action, configure} from ‘mobx’
configure({enforceActions: ‘observed’})
class Store {
constructor(modules) {
Object.keys(modules).forEach(moduleName => {
this[moduleName] = new modules[moduleName]({
mapStore: this.mapStore.bind(this),
rootState: this.rootState
})
})
}
rootState = {}
mapStore(moduleName) {
if (moduleName) {
return this[moduleName] ? this[moduleName] : console.error(new Error(`has no store named “${moduleName}”`))
} else {
return this
}
}
}
let $mapStore = null
let $rootState = null
class StoreModule {
constructor({mapStore, rootState}) {
$mapStore = mapStore
$rootState = rootState
}
mapStore(name) {
return $mapStore(name)
}
getRootState() {
return $rootState
}
setState(options) {
action(opt => {
Object.keys(opt).forEach(key => {
if (Object.prototype.hasOwnProperty.call(this, key)) {
this[key] = opt[key]
} else {
console.error(new Error(`mobx action “setState”: has no attribute named “${key}”`))
}
})
})(options)
}
}
export {Store, StoreModule}
8.2 创建一个状态模块, 新建 src\store\test-store.js
/**
* @name Test
* @desc
*/
import {observable, action, configure} from ‘mobx’
import {StoreModule} from ‘../utils/mobx-store’
configure({enforceActions: ‘observed’})
class Test extends StoreModule {
@observable
msg = ”
@action.bound
handleChangeMsg(e) {
this.setState({msg: e.target.value})
}
}
export default Test
8.3 配置 store
新建 src\store\index.js
/**
* @name Store
* @desc 合并全部子模块的 store
*/
import {Store} from ‘../utils/mobx-store’
import Test from ‘./test-store.js’
export default new Store({Test})
9. 注入 router 和 store
修改 index.js
import React from ‘react’
import ReactDOM from ‘react-dom’
import {BrowserRouter} from ‘react-router-dom’
import {Provider} from ‘mobx-react’
import store from ‘./store’
import App from ‘./App’
ReactDOM.render(
<Provider {…store}>
<BrowserRouter>
<App />
</BrowserRouter>
</Provider>,
document.getElementById(‘root’)
)
修改 App.js
import React, {Component} from ‘react’
import Routes from ‘./router’
class App extends Component {
render() {
return (
<div classes=”container”>
<Routes />
</div>
)
}
}
export default App
修改 src\pages\Home\index.js
/**
* @name Home
* @desc 首页
* @author
* @version
*/
import React, {Component} from ‘react’
import {inject, observer} from ‘mobx-react’
@inject(‘Test’)
@observer
class Home extends Component {
render() {
return (
<div>
<h1>Home</h1>
<p>msg: {this.props.Test.msg}</p>
<p>
<input type=”text” value={this.props.Test.msg} onChange={this.props.Test.handleChangeMsg} />
</p>
</div>
)
}
}
export default Home
11.http 请求例子
// src\store\test-store.js
/**
* @name Test
* @desc
*/
import {observable, action, configure} from ‘mobx’
import {StoreModule} from ‘../utils/mobx-store’
import {post} from ‘../utils/axios’
configure({enforceActions: true})
class Test extends StoreModule {
@observable
msg = ”
@action.bound
handleChangeMsg(e) {
this.setState({msg: e.target.value})
}
@action.bound
async getSomething() {
try {
const res = await post(‘/some-data’, { type: ‘news’})
} catch (err) {
console.error(err)
}
}
}
export default Test
12. 打包
npm run build
安装本地服务器启动工具
npm install -g serve
启动打包的项目
serve -s ./build
