vue分环境打包配置不同命令

1、安装cross-env （cross-env能跨平台地设置及使用环境变量）cnpm/npm i cross-env -D

2、新建模板红色的为相关文件

3、配置各个文件

（1）config下面的index.js

'use strict'

// Template version: 1.3.1

// see http://vuejs-templates.github.io/webpack for documentation.

const path = require('path')

module.exports = {

  dev: {

    // Paths

    assetsSubDirectory: 'static',

    assetsPublicPath: '/',

    proxyTable: {

      '/api': {

        target: 'http://xxxxx', //需要代理的后台地址 解决跨域设置

        changeOrigin: true,

        pathRewrite: {

          '^/api': ''

        }

      }

    },

    // Various Dev Server settings

    host: 'localhost', // can be overwritten by process.env.HOST

    port: 9999, // can be overwritten by process.env.PORT, if port is in use, a free one will be determined

    autoOpenBrowser: true,

    errorOverlay: true,

    notifyOnErrors: true,

    poll: false, // https://webpack.js.org/configuration/dev-server/#devserver-watchoptions-

    // Use Eslint Loader?

    // If true, your code will be linted during bundling and

    // linting errors and warnings will be shown in the console.

    useEslint: false,

    // If true, eslint errors and warnings will also be shown in the error overlay

    // in the browser.

    showEslintErrorsInOverlay: false,

    /**

     * Source Maps

     */

    // https://webpack.js.org/configuration/devtool/#development

    devtool: 'cheap-module-eval-source-map',

    // If you have problems debugging vue-files in devtools,

    // set this to false - it *may* help

    // https://vue-loader.vuejs.org/en/options.html#cachebusting

    cacheBusting: true,

    cssSourceMap: true

  },

  build: {

    prodEnv: require('./prod.env'), //新增

    testEnv: require('./test.env'),//新增

    devEnv: require('./dev.env'), //新增

    // Template for index.html

    index: path.resolve(__dirname, '../dist/index.html'),

    // Paths

    assetsRoot: path.resolve(__dirname, '../dist'),

    assetsSubDirectory: 'static',

    assetsPublicPath: './', // 前面加.

    /**

     * Source Maps

     */

    productionSourceMap: true,

    // https://webpack.js.org/configuration/devtool/#production

    devtool: '#source-map',

    // Gzip off by default as many popular static hosts such as

    // Surge or Netlify already gzip all static assets for you.

    // Before setting to `true`, make sure to:

    // npm install --save-dev compression-webpack-plugin

    productionGzip: false,

    productionGzipExtensions: ['js', 'css'],

    // Run the build command with an extra argument to

    // View the bundle analyzer report after build finishes:

    // `npm run build --report`

    // Set to `true` or `false` to always turn it on or off

    bundleAnalyzerReport: process.env.npm_config_report

  }

}

（2）config下面的 dev.evn.js

'use strict'

const merge = require('webpack-merge')

const devEnv = require('./dev.env')

module.exports = merge(devEnv, {

  NODE_ENV: '"testing"',

  ENV_CONFIG: '"test"', //新增

  BASE_URL: '"http://www.test.com"', // test测试地址

})

（4）config下面的 prod.evn.js

'use strict'

module.exports = {

  NODE_ENV: '"production"',

  ENV_CONFIG: '"prod"', // 新增

  BASE_URL: '"http://www.produciton.com"', // prod

}

（5）build下面的 build.js

'use strict'

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

// process.env.NODE_ENV = 'production' // 原本的注释掉

const ora = require('ora')

const rm = require('rimraf')

const path = require('path')

const chalk = require('chalk')

const webpack = require('webpack')

const config = require('../config')

const webpackConfig = require('./webpack.prod.conf')

// const spinner = ora('building for production...') // 原本的注释掉

const spinner = ora('building for' + process.env.NODE_ENV + 'of' + process.env.env_config + 'mode...') // 新增

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'

    ))

（8）build下面的 utils.js

'use strict'

const path = require('path')

const config = require('../config')

const ExtractTextPlugin = require('extract-text-webpack-plugin')

const packageConfig = require('../package.json')

exports.assetsPath = function (_path) {

  const assetsSubDirectory = process.env.NODE_ENV === 'production'

    ? config.build.assetsSubDirectory

    : config.dev.assetsSubDirectory

  return path.posix.join(assetsSubDirectory, _path)

}

exports.cssLoaders = function (options) {

  options = options || {}

    }

  }

        publicPath:'../../'   // 新增配置 防止打包图片（如背景图片）路径报错

      })

    } else {

      return ['vue-style-loader'].concat(loaders)

    }

  }

  return {

exports.createNotifierCallback = () => {

  return (severity, errors) => {

    if (severity !== 'error') return

    const error = errors[0]

    const filename = error.file && error.file.split('!').pop()

    notifier.notify({

      title: packageConfig.name,

      message: severity + ': ' + error.name,

      subtitle: filename || '',

      icon: path.join(__dirname, 'logo.png')

    })

  }

}

（9）api下面的 axios.js

import axios from 'axios'

import qs from 'qs'

// 生成一个 axios 实例

const instance = axios.create({

  baseURL: process.env.BASE_URL, // api 的 base_url

  timeout: 5000 // 请求 超时配置

})

// 请求 拦截器

instance.interceptors.request.use(config => {

  config.withCredentials = true

  if (config.headers['Content-Type'] === 'application/json') {

    config.data = JSON.stringify(config.data)

  }

  if (config.headers['Content-Type'] === 'multipart/form-data') {

    return config

  }

  if (config.method === 'post' || config.method === 'put' || config.method === 'delete') {

    if (typeof (config.data) !== 'string') {

      config.data = qs.stringify(config.data)

    }

  }

  return config

}, error => {

  Promise.reject(error)

})

// 响应 拦截器

axios.interceptors.response.use(response => {

  // 对响应数据做处理

  return response

}, error => {

  // 对响应错误做处理

  return Promise.reject(error)

})

export default instance

（10）api下面的 http.js

import instance from './axios'

// get请求

export function getList(params) {

  return instance({

    url: `/xxxx`,

    method: 'get',

    params

  })

}

// post请求

export function getpostList(data) {

  return instance({

    url: '/xxx',

    method: 'post',

    headers: { 'Content-Type': 'application/json' },

    data

  })

}

（11）package.json配置

"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",

    "build": "node build/build.js",

    "build:dev": "cross-env NODE_ENV=development env_config=dev node build/build.js", // 新增

    "build:test": "cross-env NODE_ENV=testing env_config=test node build/build.js",   // 新增

    "build:prod": "cross-env NODE_ENV=production env_config=prod node build/build.js" // 新增

  },

完整的分环境打包就完成了。。。。

执行对应的命令

1、cnpm/npm run build:dev ------本地包打包完成

2、cnpm/npm run build:test ------测试包打包完成

3、cnpm/npm run build:prod ------生产包打包完成
