Vue+Electron学习系列 (三) -- 自动更新

electron+vue打包后自动检测版本并更新

前提(默认已安装如下扩展)：

    vue：3.0.0-rc.12

    electron: 10.1.1

    electron-updater: 4.3.4

配置文件设置

// vue.config.js 默认无此文件，可自行在根目录下创建
module.exports = {
  //vue配置
  publicPath: process.env.NODE_ENV ==='production' ? './' : '/',

  pluginOptions: {
    electronBuilder: {
      builderOptions: {
          ...
          //此处省略打包配置参数
         ...
        //发布更新
        //增加此配置主要是打包时可生成latest.yml文件
        publish: [{
          provider: "generic",
          url: "http://localhost/releases/"          
        }]
      }
    }
  }
};

仅需在主进程监听即可(上代码)

// 注意此处使用electron-log
'use strict'
