I have an Electron app. I try to make the app open an .exe file. I created a directory in the root folder named lib and placed the .exe file there. In developme

Answer 1

there I found a new solution, using electron-packager on Windows do not add the files into the resources folder at the end of the process.

So I added this command into the package.json

"build-win": "electron-packager . --platform=win32 --asar --prune --arch=ia32 --extra-resource=./extraResources/documents/QuickStartGuideWN-H1.pdf --extra-resource=./extraResources/MAC_drivers/MacOS10.14/ --icon=assets/alfa_a.ico --out ./dist --overwrite",

And now the files are insied the resource fodlder just add

--extra-resource=./extraResources/file

Answer 2

Add the following code to package.json:

 "build": {
    "extraResources": [
      {
        "from": "./src/extraResources/",
        "to": "extraResources",
        "filter": [
          "**/*"
        ]
      }
    ]
  }

Then, you can access the files using

const configFile = path.join(path.dirname(__dirname), 'extraResources','config.json');

I use the following folders structure which allows me to run the app any way.

from project folder: node_modules\.bin\electron.cmd src\main\index.js

from unpacked source dist\win-unpacked\app.exe check-for-update

from installed folder C:\Users\user\AppData\Local\Programs\app\app.exe

+-- dist
|   +-- win-unpacked
|      +-- resources
|         +-- extraResources
|            config.json
+-- node_modules
+-- src 
|   +-- extraResources
|      config.json
|      someFile.js
|   +-- main
|      index.js
|   +-- render
|      index.js

Managed to solve it by using extraResources. Should be declared under build in your package.json file.

For example:

1. Create a new folder named extraResources adjacent to pacakge.json

2. Add the following code to your package.json file:

   "build": { "extraResources": ["./extraResources/**"] }

3. Then, you can access the files inside this folder by using __dirname + '/../extraResources/' from your main app.

Answer 4

Same as answer by @user2298995 , but got error using __dirname + '/../extraResources/filename' in windows x64.

But path.join(process.resourcesPath,'extraResources',fileName) worked fine.
