How to keep multiple subwindows open in Electron?

Question

My app structure overview:

• Main window (loaded via win.loadURL, has no access to electron).
  • Five subwindows opened via window.open(url, '_blank').

Currently, when opening multiple subwindows, the later opened will replace the former opened, how to keep them all open, instead of replacing each other?

Update: in Electron 15, nativeWindowOpen defaults to true.

You should enable nativeWindowOpen on your main window.

new BrowserWindow({ webPreferences: { nativeWindowOpen: true } })

Then, each window.open call (assuming you aren't using the same window name, not counting special window names like '_blank') will open a brand new window.
