ElectronIpcRenderer.sendSync method

ElectronIpcRenderer › sendSync

Unofficial

Sends a message to the main process via channel and expects a result synchronously.

The main process handles it by listening for channel with the ipcMain module and replies by setting event.returnValue. Sending a synchronous message blocks the whole renderer process until the reply is received, so use this only as a last resort.

Signature:

sendSync(channel: string, args?: unknown[]): unknown

Parameters:

Parameter	Type	Description
channel	string	The IPC channel name.
args?	unknown[]	Arguments to send.

Returns: unknown — The value sent back by the ipcMain handler.
