VUE2.7项目配置webpack打包-详细操作步骤

55 阅读 0 评论

一、Webpack简介

　　Webpack是一个打包工具，可以把JS、CSS、Node Module、Coffeescrip、SCSS/LESS、图片等都打包在一起，因此，现在几乎所有的SPA项目、JS项目都会用到Webpack。

官网：https://webpack.js.org  

GitHub为https://github.com/webpack/ webpack 

二、创建基于Webpack的Vue2.7.js项目

　　Webpack+Vue.js的方式来做项目的，这样才可以做到“视图”“路由”“component”等的分离，以及快速打包、部署及项目上线。

1. Webpack 的相关命令，以及项目常用到的命令，我全部放这里，请务必按照版本安装！！！

"cross-env": "^7.0.2",

"vue-template-compiler": "^2.6.14",

"webpack": "^5.70.0",

"webpack-dev-server": "^4.7.4"

"compression-webpack-plugin": "^9.2.0",

"css-loader": "^4.1.0",

"friendly-errors-webpack-plugin": "^1.7.0",

"is-glob": "^4.0.3",

"monaco-editor": "^0.27.0",

"monaco-editor-webpack-plugin": "^4.2.0",

"process": "^0.11.10",

"style-loader": "^3.3.1",

"stylus-loader": "^6.2.0",

"vue-loader": "^15.11.1",

"vue-style-loader": "^4.1.0",

"webpack-bundle-analyzer": "^4.5.0",

"webpack-cli": "^4.10.0",

"webpack-merge": "^5.8.0",

"webpackbar": "^5.0.2"

"cross-env": "^7.0.2",

package.json代码：

 "scripts": {
    "build:private": "cross-env CONFIG_ENV=private  webpack --config build/webpack.prod.js",
    "start:private": "cross-env CONFIG_ENV=private  webpack-dev-server --open --hot --config ./build/webpack.dev.js"
  },

2. 文件配置 

看下文件目录结构：

1）build/config.js文件：

'use strict'
// Template version: 1.3.1
// see http://vuejs-templates.github.io/webpack for documentation.

const path = require('path')

let env
switch (process.env.CONFIG_ENV) {
  case 'local':
    env = require('../config/local.env')
    break
  case 'dev':
    env = require('../config/dev.env')
    break
  case 'stage':
    env = require('../config/stage.env')
    break
  case 'pro':
    env = require('../config/prod.env')
    break
  case 'private':
    env = require('../config/private.env')
    break
  default:
    break
}

module.exports = {
  shouldAnalyzerBundle: false,
  shouldSplitChunks: false,
  shouldGzipResource: false,
  htmlWebpackConfig: {
    // author: 'AnbanTech@FrontendTeam',
    // license: 'Copyright © 2019-2022 Anban Inc. All Rights Reserved. 安般科技.',
    title: '报告'
    // keywords: 'webpack, vue',
    // descritpion: 'learn how to config webpack to build vue project'
  }
}

 2）build/webpack.base.js文件：（重点分析）

const path = require('path')
const { resolve } = path
const MonacoWebpackPlugin = require('monaco-editor-webpack-plugin')
const HtmlWebpackPlugin = require('html-webpack-plugin')
const { htmlWebpackConfig, shouldSplitChunks } = require('./config')
const WebpackBar = require('webpackbar')

const CopyWebpackPlugin = require('copy-webpack-plugin')
const MiniCssExtractPlugin = require('mini-css-extract-plugin')
const { BundleAnalyzerPlugin } = require('webpack-bundle-analyzer')
const FriendlyErrorsWebpackPlugin = require('friendly-errors-webpack-plugin')

const isDev = process.env.NODE_ENV !== 'production'
function genereateAssetsLoader(shouldSplitChunks) {
  if (shouldSplitChunks) {
    return [
      {
        test: /\.(woff|woff2|eot|otf|ttf)$/,

    ]
  } else {

3.运行命令和打包命令：

npm run start:private

npm run build:private

完结撒花ヽ(°▽°)ノ

其实我写的过程，不断地出现报错，坚持住，不断地解决掉！！

当前配置有些冗余的代码文件，后续还需要优化
