React全家桶环境搭建过程

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.jsconst 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.jsconst 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 .lessresolve: {extensions: ['.ts', '.tsx', '.js', '.jsx', '.less', '.css']},module: {rules: [{test: /\.css$/,use: ['style-loader', 'css-loader']},//import less modules，name：demo__demo___hash{test: /\.less/,use: ['style-loader','typings-for-css-modules-loader?modules&importLoaders=1&localIdentName=[name]__[local]___[hash:base64:5]&namedExport&camelCase&less!less-loader']},{test: /\.(png|svg|jpg|gif)$/,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} ><div 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></div></Router>,document.getElementById('root'));
