在 electron-builder 中检索或指定输出文件名

Retrieve or Specify output file name in electron-builder

我正在以编程方式使用 electron-builder 来生成安装包。到目前为止,我将此作为我的实用程序来为当前 OS 类型创建安装包:

const packagejson = require("../package.json");
const builder = require("electron-builder");
const Platform = builder.Platform;

function buildPromise(){
    //Development package.json
    const devMetadata  = packagejson.electronBuilder;

    //Application package.json
    const appMetadata = {
        name: packagejson.name,
        version: packagejson.version,
        description: packagejson.description,
        author: packagejson.author,
        productName: packagejson.productName
    };

    //Build for the current target and send back promise
    return builder.build({
        projectDir: "./",
        devMetadata,
        appMetadata
    });

}

module.exports = { 
    buildPromise,
    outputPath : packagejson.electronBuilder.directories.output
};

它所做的是从包含此部分的应用程序 MAIN package.json 文件中提取所需的元数据(因此应用程序 package.json 为空):

  ...
  "electronBuilder": {
    "build": {
      "productName": "Node App",
      "appId": "my.id",
      "asar": false,
      "win": {
        "iconUrl": "http://localhost:5000/images/logo-multi.ico",
        "target": "nsis"
      },
      "nsis" :{
        "oneClick": false
      }
    },
    "directories": {
      "output": "electron/output",
      "app":"electron/app",
      "buildResources": "electron/buildResources"
    }
  }
  ...

当我 运行 在 Windows 中构建时,我得到一个名为 Node App Setup 1.0.0.exe 的文件。到目前为止。但是我如何实际控制最终文件名呢?或者至少以编程方式检索该文件名,以便我可以读入它并以某种方式响应客户端?显然,我可以从 json 文件设置中拼凑出来,但我希望它更明确。

应作者的要求,作者将其添加到当前版本 (8.5.1) 中:

https://github.com/electron-userland/electron-builder/issues/899

所以现在我们可以做:

builder.build()
    .then(paths => {
        //paths contains an array of export file paths, e.g.:
        console.log(paths[0]); //= c:/MyProject/dist/My Project Setup 1.0.0.exe
        console.log(paths[1]); //= c:/MyProject/dist/myproject-1.0.0-x86_64.AppImage
    });

您可以在 package.jsonbuild 部分使用 artifactName 指定输出文件名。

文档说 artifact file name template 支持 ${ext} 宏:

${ext} macro is supported in addition to file macros.

文件宏

You can use macros in the file patterns, artifact file name patterns and publish configuration url:

${arch} — expanded to ia32, x64. If no arch, macro will be removed from your pattern with leading space, - and _ (so, you don't need to worry and can reuse pattern).
${os} — expanded to mac, linux or win according to target platform.
${name} – package.json name.
${productName} — Sanitized product name.
${version} — from package.json
${channel} — detected prerelease component from version (e.g. beta).
${env.ENV_NAME} — any environment variable.
Any property of AppInfo (e.g. buildVersion, buildNumber).

例子

"build": {
    "appId": "com.electron.app.my",
    "artifactName": "node-app-${version}.${ext}",
    ...
},

如果您的包版本是 1.0.0,Windows 目标将输出:

node-app-1.0.0.exe
