1.安装软件
(1) nodejs node下载链接
(2) npm包管理 (安装nodejs的时候已经安装了npm包管理)
2.更换npm库的源
由于国内网络环境问题，配置阿里的npm库源
npm config set registry https://registry.npm.taobao.org
3.构建项目
3.1 选择一个目录，用webstorm构建一个空白的项目
3.2 配置依赖库
打开控制台切到项目所在目录，在控制台里输入npm init 命令来初始化一个package.json文件，这个文件是一个类似于pom.xml的文件，用来描述需要的依赖库。
package.json内容：
{
"name": "myfirstreact","version": "1.0.0","description": "\"我的第一个react程序\"","main": "index.js","dependencies": {
"babel": "^6.5.2","webpack": "^1.14.0","webpack-dev-server": "^1.16.2"
},"devDependencies": {
"babel": "^6.5.2","babel-loader": "^6.2.10","babel-preset-es2015": "^6.18.0","babel-preset-react": "^6.16.0","babel-preset-stage-0": "^6.16.0","css-loader": "^0.26.1","eslint": "^3.13.1","eslint-plugin-react": "^6.9.0","file-loader": "^0.9.0","jquery": "^3.1.1","less-loader": "^2.2.3","react": "^15.4.2","react-dom": "^15.4.2","react-hot-loader": "^1.3.1","style-loader": "^0.13.1","url-loader": "^0.5.7","scripts": {
"start": "node server.js","lint": "eslint src"
},"author": "","license": "ISC"
}
3.3 安装需要的文件
npm install webpack webpack-dev-server babel --save-dev
npm install react react-dom babel-loader less-loader css-loader style-loader url-loader file-loader babel-preset-es2015 babel-preset-react react-hot-loader jquery eslint eslint-plugin-react --save-dev
--save-dev 会把下载包的相关信息写到package.json的devDependencies里面方便以后发布，其他人使用的时候只需要npm install就可以把相关的依赖下载到当前的项目里面。
在package.json里面包的版本之前的^表示可以安装类似2.x.x版本的组件但是不能安装3.x.x版本的软件
在package.json里面包的版本之前的~表示可以安装2.1.x的软件不能安装2.3.x的软件
3.4 新建一个webpack.config.js的文件
在文件里面添加如下信息
'use strict';
var webpack = require('webpack');
var commonsPlugin = new webpack.optimize.CommonsChunkPlugin('common.js');
var path = require('path');
module.exports = {
devtool: 'eval',entry: [
'webpack-dev-server/client?http://localhost:3000','webpack/hot/only-dev-server','./src/js/entry.js'
],output: {
path: path.join(__dirname,'dist'),filename: 'bundle.js',publicPath: '/static/'
},plugins: [
new webpack.HotModuleReplacementPlugin(),commonsPlugin
],module: {
loaders: [
{
test: /\.css$/,loader: 'style-loader!css-loader'
},{
test: /\.jsx?$/,loaders: ['react-hot','babel'],exclude: /node_modules/,},{
test: /\.(png|jpg)$/,loader: 'url-loader?limit=8192'
},{
test: /\.less$/,loader: 'style-loader!css-loader!less-loader'
},{
test: /\.woff(2)?(\?v=[0-9]\.[0-9]\.[0-9])?$/,loader: "url-loader?limit=10000&mimetype=application/font-woff"
},{
test: /\.(ttf|eot|svg)(\?v=[0-9]\.[0-9]\.[0-9])?$/,loader: "file-loader"
}
]
},resolve: {
root:'',extensions: ['','.js','.json','.less']
}
};
3.5新建一个.babelrc的文件
里面的内容如下：
{
"presets": ["es2015","stage-0","react"]
}
上面的是babel插件的相关信息
3.6 新建一个.eslintrc的文件
里面的内容如下：
{
"ecmaFeatures": {
"jsx": true,"modules": true
},"env": {
"browser": true,"node": true
},"parser": "babel-eslint","rules": {
"quotes": [2,"single"],"strict": [2,"never"],"react/jsx-uses-react": 2,"react/jsx-uses-vars": 2,"react/react-in-jsx-scope": 2
},"plugins": [
"react"
]
}这个配置是设置js的代码相关规范的
3.7新建server.js文件
添加以下内容：
var webpack = require('webpack');
var WebpackDevServer = require('webpack-dev-server');
var config = require('./webpack.config');
new WebpackDevServer(webpack(config),{
publicPath: config.output.publicPath,hot: true,inline:true,historyApiFallback: true
}).listen(3000,'localhost',function (err,result) {
if (err) {
return console.log(err);
}
console.log('Listening at http://localhost:3000/');
});
3.8创建index.html文件
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>myFirstReact</title>
</head>
<body>
<div id="root"></div>
<script type="text/javascript" src="/static/common.js" charset="utf-8"></script>
<script type="text/javascript" src="/static/bundle.js" charset="utf-8"></script>
</body>
</html>
3.9 创建src/js文件夹
3.9.1 创建src/js/helloworld.js：
import React,{ Component } from 'react';
export default class Hello extends Component {
render() {
return (
<div>
<h1>Hello,world.</h1>
<p>this is a simple section</p>
<p>终于搭建成功了</p>
</div>
);
}
}
3.9.2 创建src/js/entry.js:
import React from 'react';
import ReactDOM from 'react-dom';
import Hello from './helloworld';
ReactDOM.render(<Hello />,document.getElementById('root'));
4 在控制台运行npm run start,
5 在浏览器中输入http://localhost:3000/查看到如下内容：
