Vue如何实现多页面配置以及打包方式

为什么会用多页面

在开发时，对于同一类型的多网站，多页面大大节省开发时间，只需要配置一次就可以实现多次开发变成单次开发，同时一个包就可以展示一整个网站

如何在vue.config.js配置多页面信息

多页面打包会打包多个.html文件，根据.html配置跳转地址就可以了

目录（四个页面）

配置打包相关

//引入打包组件
const FileManagerPlugin = require('filemanager-webpack-plugin')
//配置打包信息
const fs = require('fs')
const path = require('path')
const FileManagerPlugin = require('filemanager-webpack-plugin')
const productionDistPath = './productionDist'
// 是否打包
const isProduction = process.env.NODE_ENV === 'production'
// 打包环境变量
const envType = process.env.ENV_TYPE || 'prod'
module.exports = {
	// 打包生成压缩包
      const fileManagerPlugin = new FileManagerPlugin({
        //初始化 filemanager-webpack-plugin 插件实例
        events: {
          onEnd: {
            delete: [
              //首先需要删除项目根目录下的dist.zip
              productionDistPath
            ],
            archive: [
              //然后我们选择dist文件夹将之打包成dist.zip并放在根目录
              {
                source: './dist',
                destination: getCompressionName()
              }
            ]
          }
        }
      })
      config.plugins.push(fileManagerPlugin)
}
// 获取打包压缩包路径
function getCompressionName() {
  try {
    const projectName = JSON.parse(fs.readFileSync('package.json')).name
    return `${productionDistPath}/${projectName}-${new Date().getTime()}-${envType}.zip`
  } catch (e) {
    return `${productionDistPath}/dist.zip`
  }
}
function resolve(dir) {
  return path.join(__dirname, dir)
}
