Env vars更改project.json中的应用程序名称并设置运行时vars? [英] Env vars to change app name in project.json and set runtime vars?

问题描述

我需要从相同的代码库(例如"pro"和"lite"版本)生成两个应用.这里有很多问题，但我发现没有一个涉及 node 或 electron .

I need to generate two apps from the same codebase (e.g. "pro" and "lite" versions). There are a lot of questions here about this but none I found involve node or electron.

我仅以非常简单的方式在开发中使用过 env ，并且在四处搜寻之后，我再也没有提到能够在已部署的应用程序中使用它们的情况.

I have only used env in development in very simple ways and after searching around, I haven't seen any mention of being able to use them in a deployed application.

所以有两个任务:
1.更改应用名称

因此，将 package.json 文件与 electron builder 结合使用，我试图像这样更改 productName :

So, using the package.json file with electron builder, I've tried to change the productName like this:

  "productName": process.env.APP_NAME,
  "main": "main.js",
  "scripts": {
    "package-mac": process.env.APP_NAME='Bingo' electron-packager . --overwrite  --platform=darwin --arch=x64  --prune=true --out=release-builds"
}

但是那没有用.还看到了这种构造，但也没有用:

But that didn't work. Also saw this construction but it also didn't work:

  "productName": '${process.env.APP_NAME}',

我在这里走错了路吗?

2.在运行时使用的变量
做亲"&轻型"事物，我至少需要一个标志才能知道如何配置事物.
反过来， env vars是否适合吗?

2. Vars for use at runtime
To do the "pro" & "lite" thing, I need at least a flag to know how to configure things.
Are env vars in anyway suitable for this?

我想我是否能够更改应用程序名称，我可以在运行时访问它，但似乎所有这些东西都缺少重要的内容.

I guess if I am able to change the app name, I can access that at runtime but it seems like I am missing something important with all this.

推荐答案

使用 dot-json ，您可以使用npm脚本，例如:

Using dot-json, you can have npm scripts like:

  "productName": "Bingo",
  "main": "main.js",
  "scripts": {
    "package-mac": "echo $APP_NAME; dot-json package.json productName $APP_NAME --indent 2; electron-packager . --overwrite  --platform=darwin --arch=x64  --prune=true --out=release-builds"
  }

在终端中，也许您可​​以运行

In Terminal, maybe, you can run

 $ APP_NAME='Bingo Pro' npm run package-mac
