What are these extra processes?

Question

In my Electron app, I have my main process and two renderer windows open. Why does Task Manager show 8 "electron.exe" processes? I would expect it to be 3.

Thanks.

Answer 1

Extra processes are electron listeners.

A new process will spawn every time you add a listener to ipcMain or ipcRenderer.

Example:

ipcRenderer.on("data", (e, data) => {
  console.log("this will spawn a process")
})

• If you start your app:

  • 

• If you add a listener:

  • 

• If a window is visible, Windows joins them all in a group:

  • 

Just wondering if there's any way to specify a process id or something to join them together...
