React全家桶环境搭建过程详解

本文介绍了React全家桶环境搭建过程详解，分享给大家，具体如下：

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'
 

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 (
     (
      
    )}/>
  );
}

ReactDom.render(
  
    
      

 
Homes
 
TodoList
      
      
 
 {}
 
      
    
  ,
  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"]
}
