Parameter decorators

You can inject Electron-specific context directly into your controller methods without parsing the raw event object manually.

Decorator	Injects	Type
`@Channel()`	The IPC channel name for this handler (e.g. `"users.get_profile"`)	`string`
`@CorrelationId()`	The unique ID for the current request context. If you have correlation disabled, this will always return undefined	`string`
`@Origin()`	The sender frame	`WebFrameMain`
`@ProcessId()`	The ID of the renderer process	`number`
`@RawEvent()`	The native Electron event object	`IpcMainEvent` \| `IpcMainInvokeEvent`
`@Sender()`	The `WebContents` that sent the message	`WebContents`
`@Window()`	Nullable. The `BrowserWindow` that sent the message	`BrowserWindow`

Example:

import type { WebContents } from "electron/main";

@IpcHandle()
getUserProfile(
  @Sender() sender: WebContents,
  userId: string
) {
  console.log(`Request from window: ${sender.id}`);
  return this.userService.findById(userId);
}

note

When using the generated types in the frontend, these injected parameters are automatically removed from the function signature. You simply call getUserProfile('123').
