+# useIpcRendererOn
+

+
+## Usage
+
+```ts
+import { useIpcRendererOn } from '@vueuse/electron'
+
+// enable nodeIntegration if you don't provide ipcRenderer explicitly
+// see: https://www.electronjs.org/docs/api/webview-tag#nodeintegration
+// remove listener automatically on unmounted
+useIpcRendererOn('custom-event', (event, ...args) => {
+  console.log(args)
+})
+```
+
+## Type Declarations
+
+```ts
+/**
+ * Listens to channel, when a new message arrives listener would be called with listener(event, args...).
+ * [ipcRenderer.removeListener](https://www.electronjs.org/docs/api/ipc-renderer#ipcrendererremovelistenerchannel-listener) automatically on unmounted.
+ *
+ * You need to provide `ipcRenderer` to this function.
