Variable listenOnce

Type Declaration

• • <TArgs extends any[] = any[], TResult = any>(
        fn: IpcListener<TArgs, TResult, IpcEventMap>,
    ): CloneableChannel<
        ListenerDef<TArgs, TResult, IpcEventMap>,
        TArgs,
        unknown,
    >

  • Register a one-shot fire-and-forget channel via ipcMain.once.

    Process-scoped like handleOnce: the first message from any window consumes the listener, and later sends are silently ignored.

    Type Parameters

    • TArgs extends any[] = any[]
    • TResult = any

    Parameters

    • fn: IpcListener<TArgs, TResult, IpcEventMap>

    Returns CloneableChannel<ListenerDef<TArgs, TResult, IpcEventMap>, TArgs, unknown>
