vue+webpack项目环境搭建

首先安装node.js

下载地址：https://nodejs.org/en/download/

看下是否成功安装 node -v

安装webpack，命令行npm install webpack -g

npm是国外的，使用起来比较慢，我们这里使用淘宝的cnpm镜像来安装vue，命令行npm install -g cnpm --registry=https://registry.npm.taobao.org

安装完npm镜像后，开始安装全局vue-cli脚手架，命令行npm install --global vue-cli

环境搭建好之后，开始创建项目

在指定目录创建文件存放项目，进入当前目录，shift+鼠标右键，在此处打开命令窗口，命令行vue init webpack "项目名称"

安装阶段需要用户输入一些信息

安装成功之后进入当前项目，命令行 cd “项目文件夹”

下载依赖，命令行npm install

运行项目，命令行npm run dev

打包项目，命令行npm run build

分环境打包

1、build文件夹新建sit.js

sit.js

'use strict'
require('./check-versions')()

process.env.NODE_ENV = 'production'

const ora = require('ora')
const rm = require('rimraf')
const path = require('path')
const chalk = require('chalk')
const webpack = require('webpack')
const config = require('../config')
config.build.index = path.resolve(__dirname, '../dist/sit/index.html')
config.build.assetsRoot = path.resolve(__dirname, '../dist/sit')
config.build.assetsPublicPath = '' // 这也可以改为sit的CDN路径
config.build.sit = true
config.build.autodDeploy = true
const webpackConfig = require('./webpack.prod.conf')

const spinner = ora('building for sit...')
spinner.start()

rm(path.join(config.build.assetsRoot, config.build.assetsSubDirectory), err => {
  if (err) throw err
  webpack(webpackConfig, (err, stats) => {
    spinner.stop()
    if (err) throw err
    process.stdout.write(stats.toString({
      colors: true,
      modules: false,
      children: false, // If you are using ts-loader, setting this to true will make TypeScript errors show up during build.
      chunks: false,
      chunkModules: false
    }) + '\n\n')

    if (stats.hasErrors()) {
      console.log(chalk.red('  Build failed with errors.\n'))
      process.exit(1)
    }

    console.log(chalk.cyan('  Build complete.\n'))
    console.log(chalk.yellow(
      '  Tip: built files are meant to be served over an HTTP server.\n' +
      '  Opening index.html over file:// won\'t work.\n'
    ))
  })
})

2、config文件夹新建sit.env.js

sit.env.js

'use strict'
const merge = require('webpack-merge')
const devEnv = require('./dev.env')

module.exports = merge(devEnv, {
  NODE_ENV: '"sit"'
})

3、webpack.prod.conf.js引入sit.env.js

const env = process.env.NODE_ENV === 'sit'
  ? require('../config/sit.env')
  : require('../config/prod.env')

4、package.json新加打包命令

"scripts": {
    "dev": "webpack-dev-server --inline --progress --config build/webpack.dev.conf.js",
    "start": "npm run dev",
    "unit": "jest --config test/unit/jest.conf.js --coverage",
    "e2e": "node test/e2e/runner.js",
    "test": "npm run unit && npm run e2e",
    "lint": "eslint --ext .js,.vue src test/unit test/e2e/specs",
    "sit": "node build/sit.js",
    "build": "node build/build.js"
  },

5、sit测试环境打包命令 npm run sit 就大功告成

基于上述内容新加一些简单的需要的配置

1、生产包：npm run build 去掉console

webpack.prod.conf.js

new UglifyJsPlugin({
      uglifyOptions: {
        compress: {
          warnings: false,
          drop_debugger: !config.build.sit, //true代表去掉debugger
          drop_console: !config.build.sit // true代表去掉console
        }
      },
      sourceMap: config.build.productionSourceMap,
      parallel: true
    }),

2、sit测试环境下命令打包上传部署

下载依赖： npm install webpack-sftp-client -D

webpack.prod.conf.js引入

const WebpackSftpClient = require('webpack-sftp-client')

if (config.build.autodDeploy) {
  console.log('执行SIT部署')
  new WebpackSftpClient({
    port: '22',
    host: 'exmaple.com',
    username: 'root',
    password: 'password',
    path: config.build.assetsRoot,
    remotePath: '/data/website/demo/',
    // Show details of uploading for files
    verbose: true
  })
}
