这次给大家带来React全家桶环境搭建代码解析，React全家桶环境搭建的注意事项有哪些，下面就是实战案例，一起来看一下。
环境搭建
1.从零开始搭建webpack+react开发环境
2.引入Typescript
安装依赖
npm i -S @types/react @types/react-dom npm i -D typescript awesome-typescript-loader source-map-loader
新建tsconfig.json
{
"compilerOptions": {
"outDir": "./dist/",
"sourceMap": true,
"noImplicitAny": true,
"module": "commonjs",
"target": "es5",
"jsx": "react"
},
"include": [
"./src/**/*"
]
}修改webpack.config.js
// webpack.config.js
const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const webpack = require('webpack');
module.exports = {
entry: {
index:'./src/index.js',
},
output: {
filename: 'bundle.js',
path: path.resolve(dirname, 'dist')
},
devtool: "source-map",
// Add '.ts' and '.tsx' as resolvable extensions.
resolve: {
extensions: ['.ts', '.tsx', '.js', '.jsx']
},
module: {
rules: [
{
test: /\.css$/,
use: ['style-loader', 'css-loader']
},
{
test: /\.(png|svg|jpg|gif)$/,
use: ['url-loader']
},
{
test: /\.(woff|woff2|eot|ttf|otf)$/,
use: ['url-loader']
},
{
test: /\.(js|jsx)$/,
exclude: /node_modules/,
use: {
loader: 'babel-loader'
}
},
// All files with a '.ts' or '.tsx' extension will be handled by 'awesome-typescript-loader'.
{
test: /\.tsx?$/,
loader: "awesome-typescript-loader"
},
]
},
plugins: [
new HtmlWebpackPlugin({
title: 'production',
template: './index.html'
}),
new webpack.NamedModulesPlugin(),
new webpack.HotModuleReplacementPlugin()
],
devServer: {
contentBase: './dist',
hot: true
},
};3.引入less并支持import less modules
安装依赖
npm i -D less less-loader npm i -D typings-for-css-modules-loader
tips:typings-for-css-modules-loader
打包时将样式模块化，我们可以通过import或require引入样式，并且相互不冲突。
//demo.less -> demo.less.d.ts
//.demo{color:red;} -> export const demo: string;
import * as styles from 'demo.less'
<DemoComponent className={styles.demo} />修改webpack.config.js
// webpack.config.js
const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const webpack = require('webpack');
module.exports = {
entry: {
index:'./src/index.js',
},
output: {
filename: 'bundle.js',
path: path.resolve(dirname, 'dist')
},
devtool: "source-map",
//add .less
resolve: {
extensions: ['.ts', '.tsx', '.js', '.jsx', '.less', '.css']
},
module: {
rules: [
{
test: /\.css$/,
use: ['style-loader', 'css-loader']
},
//import less modules，name：demodemo_hash
{
test: /\.less/,
use: [
'style-loader',
'typings-for-css-modules-loader?modules&importLoaders=1&localIdentName=[name][local]_[hash:base64:5]&namedExport&camelCase&less!less-loader'
]
},
{
test: /\.(png|svg|jpg|gif)$/,
use: ['url-loader']
},
{
test: /\.(woff|woff2|eot|ttf|otf)$/,
use: ['url-loader']
},
{
test: /\.(js|jsx)$/,
exclude: /node_modules/,
use: {
loader: 'babel-loader'
}
},
{
test: /\.tsx?$/,
loader: "awesome-typescript-loader"
},
]
},
plugins: [
new HtmlWebpackPlugin({
title: 'production',
template: './index.html'
}),
new webpack.NamedModulesPlugin(),
new webpack.HotModuleReplacementPlugin()
],
devServer: {
contentBase: './dist',
hot: true
},
};4.引入react-routerv4
npm i -S react-router-dom
创建history
import { createHashHistory } from 'history';
export default createHashHistory();使用
import React from 'react';
import ReactDom from 'react-dom';
import * as styles from "./index.less";
import history from './helpers/history';
import {Router, Route, Switch, Redirect, Link} from 'react-router-dom';
import Hello from "./router/Hello";
import TodoList from "./router/TodoList";
const PrivateRoute = ({ component: Component , ...rest}) => {
return (
<Route {...rest} render={props => (
<Component {...props}/>
)}/>
);
}
ReactDom.render(
<Router history={history} >
<p className={styles.wrap}>
<ul>
<li><Link to="/">Homes</Link></li>
<li><Link to="/todo">TodoList</Link></li>
</ul>
<Switch>
<Route exact path="/" component={Hello}/>
{/*<Route path="/demo" component={Demo}/>*/}
<PrivateRoute path="/todo" component={TodoList} />
</Switch>
</p>
</Router>,
document.getElementById('root')
);...ES7语法报错
npm i -S babel-preset-stage-2
修改.babelrc
{
"presets": ["es2015", "react", "stage-2"],
}5.引入mobx状态管理
npm i -S mobx mobx-react
使用装饰器语法
修改tsconfig.json
"compilerOptions": {
"target":"es2017", //fix mobx.d.ts error
"experimentalDecorators": true,
"allowJs": true
}npm i -D babel-plugin-transform-decorators-legacy
修改.babelrc
{
"presets": ["es2015", "react", "stage-2"],
"plugins": ["transform-decorators-legacy"]
