Function: createValidatedInvoker()

function createValidatedInvoker<TChannel>(
    channel: TChannel,
    validateResult: (
        candidate: unknown
    ) => SafeParseLike<IpcInvokeChannelResult<TChannel>>,
    options?: ResultValidationOptions
): (
    ...args: IpcInvokeChannelParams<TChannel>
) => Promise<IpcInvokeChannelResult<TChannel>>;

Defined in: electron/preload/core/bridgeFactory.ts:673

Creates a typed IPC invoker that additionally validates the successful response payload.

Type Parameters

TChannel

TChannel extends keyof IpcInvokeChannelMap

Parameters

channel

TChannel

validateResult

(candidate: unknown) => SafeParseLike<IpcInvokeChannelResult<TChannel>>

options?

ResultValidationOptions = {}

Returns

(...args: IpcInvokeChannelParams<TChannel>) => Promise<IpcInvokeChannelResult<TChannel>>

Remarks

The main process is generally trusted, but this adds defense-in-depth against malformed payloads caused by:

• Handler bugs/regressions,
• Database corruption producing invalid domain objects,
• Version skew during development hot reload.

When validation fails, this helper:

1. Logs a structured warning in preload diagnostics,
2. Forwards a diagnostics report to the main process,
3. Throws an IPC error so the renderer can surface the failure.
