五、build目录下配置文件之webpack.dev.conf.js
webpack.prod.conf.js也差不多。这2者之间的差别以后再讨论。
/**
* 此文件用于开发环境下的webpack配置
* 就本项目执行npm run dev 和 npm run start都会用到这个文件的配置
* 具体可以参考JavaScript中"scripts"的配置
*/
'use strict'
const utils = require('./utils')
const webpack = require('webpack')
const config = require('../config')
const merge = require('webpack-merge')
const path = require('path')
const baseWebpackConfig = require('./webpack.base.conf')
const CopyWebpackPlugin = require('copy-webpack-plugin')
//生成html文件
const HtmlWebpackPlugin = require('html-webpack-plugin')
//friendly-errors-webpack-plugin:把webpack的错误和日志搜集起来展现给用户
const FriendlyErrorsPlugin = require('friendly-errors-webpack-plugin')
const portfinder = require('portfinder')
