Multiple targets not working via Programmatic API

• Version: 18.6.2

• Target: osx, windows, linux (tried variations of arch and target types, thats not the issue here)

The programmatic API docs shows an example with:

builder.build({
  targets: Platform.MAC.createTarget(),
  config: {
   "//": "build options, see https://goo.gl/ZhRfla"
  }
})

And it works perfectly fine for a single platform build, same for Linux and Windows. However, whenever I try passing multiple targets, e.g.:

targets: [Platform.WINDOWS.createTarget('squirrel', Arch.ia32), Platform.LINUX.createTarget('appimage', Arch.ia32), Platform.MAC.createTarget()]

It throws an error:

electron-builder 18.6.2
[14:40:00] Error: Unknown platform: windows,[object Map]
    at Packager.createHelper (/Users/paulius/Code/timer-app/node_modules/electron-builder/src/packager.ts:319:15)

Am I doing something wrong here or are multiple targets just not supported?

Also it seems to override the config, for example it built a Mac version with .dmg, .zip and yml update file… whereas in the config I am targeting mas and normally just passing targets: Platform.MAC.createTarget() would create a MAS build as expected.

I changed mac: ["default"] to mac: ["mas"] and it’s building MAS versions now

Yes, squirrel is a correct target name, fixed.

Yep, that seems to work now

Better to build x64 AppImage 😃

Ran without errors, but what about the poor 32-bit users? 😄

My solution:

const config = { ... };
const targets = new Map()
    .set(Platform.LINUX, new Map())
    .set(Platform.WINDOWS, new Map());
    .set(Platform.MAC, new Map());

builder.build({
    targets,
    config,
})
