压缩电子应用程序的大小

Question

我开发了 Angular-Electron 应用程序。它是一个简单的应用程序，但其大小为 159Mb。我使用 Electron 构建器来构建 Electron 应用程序并包含自动更新包。当我解压 asar 文件时，它有节点模块。当我指定不时在package.json中包含节点模块，应用程序的大小减少到89mb，但应用程序没有运行。这是我的 package.json

有没有其他方法可以减少电子应用程序的文件大小

Answer 1

您可以将compression级别从“正常”更改为“最大” package.json：

"build": {
    "appId": "com.electron.example",
    "compression": "maximum",
    // other build settings
}

这通常可以为您节省很多应用程序大小，具体取决于您之前的压缩设置以及您的构建中的静态文件和添加的功能、代码和/或依赖项的数量。

更新

不管怎样，如果你的应用程序相对接近~80Mb，你不会节省太多，因为这通常是电子构建的大小（包含节点、铬和API..）。
