使用webpack构建react - 配置篇

首先配置webpack配置文件： ./config/dev.js

const path = require("path");
const WebpackHtmlPlugin = require('webpack-html-plugin');
//配置webpack-html-plugin 插件
const webpackHtmlPlugin = new WebpackHtmlPlugin({
    filename:"index.html",
    template:path.resolve(__dirname,"../","index.html"),
    inject:"body"
});

module.exports = {
    entry:{
        app:path.resolve(__dirname,"../src","main.js")
    },
    output:{
        path:path.resolve(__dirname,"../dist"),
        filename:"js/[name].js"
    },
    plugins:[
        webpackHtmlPlugin
    ],
    module:{
        rules:[
            {
                test:/\.(js|jsx)$/,
                loader:"babel-loader"
            }
        ]
    },
    devServer:{//配置本地开发测试环境
        contentBase:path.resolve(__dirname,"../dist"), //配置本地服务器的启动根目录
        port:3000,
        inline:true,
    }
}
