extraMetadata not working

[sunknudsen]

• Electron-Builder Version: 23.4.0

• Node Version: v16.16.0

• Electron Version: 19.0.12
• Electron Type (current, beta, nightly): current

• Target: linux, mac

Using Electron Forge and Electron Builder to develop and build Electron app.

Somehow, extraMetadata props do not make their way to package.json when using following config.

$ cat electron.config.js
module.exports = {
  appId: "com.sunknudsen.test",
  artifactName: "test-${version}.${ext}",
  productName: "Test",
  dmg: {
    title: "${productName}",
  },
  linux: {
    target: {
      arch: "x64",
      target: "AppImage",
    },
  },
  mac: {
    target: {
      arch: "universal",
      target: "dmg",
    },
  },
  files: [
    {
      from: "./out/Test-darwin-arm64/Test.app/Contents/Resources/app",
      to: ".",
    },
  ],
  asarUnpack: ["**/bin/**/*", "!**/node_modules/**/*"],
  extraMetadata: {
    foo: "bar",
  },
}

$ electron-forge make && electron-builder --config ./config/electron.config.js --linux --mac

Can’t figure out what I am doing wrong… either I don’t understand feature or perhaps there is a bug.

Resulting package.json does not include any reference to foo prop.

Loosing my mind… just noticed packaged package.json is actually untouched by electron-builder… file is essentially copied from ./out/Test-darwin-arm64/Test.app/Contents/Resources/app/package.json.

Would anyone happen to know why electron-builder is not removing scripts and keywords alongside not including props from extraMetadata?

Thanks for helping out!

Figured out what causes the issue… srcDir is set to project root rather than ./out/Test-darwin-arm64/Test.app/Contents/Resources/app.

Investigating fixes…

[sunknudsen]

Adding following to files array fixed issue but feels like a hack… would be nice if one could set srcDir.

{
  filter: "package.json",
  from: ".",
  to: ".",
}
