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.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$/,
                use: ['style-loader', 'css-loader']
            },
            //import less modules,name:demo__demo___hash
            {
                test: /\.less/,
                use: [
                    'style-loader',
                    'typings-for-css-modules-loader?modules&importLoaders=1&localIdentName=[name]__[local]___[hash:base64:5]&namedExport&camelCase&less!less-loader'
                ]
            },
            {
                test: /\.(png|svg|jpg|gif)$/,
                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')
);
  • ...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"]
}
