# useIpcRenderer

Provides [ipcRenderer](https://www.electronjs.org/docs/api/ipc-renderer) and all of its APIs with Vue reactivity.

## Usage

```ts
import { useIpcRenderer } from '@vueuse/electron'
import { computed } from 'vue'

// enable nodeIntegration if you don't provide ipcRenderer explicitly
// see: https://www.electronjs.org/docs/api/webview-tag#nodeintegration
const ipcRenderer = useIpcRenderer()

// Ref result will return
const result = ipcRenderer.invoke<string>('custom-channel', 'some data')
const msg = computed(() => result.value?.msg)

// remove listener automatically on unmounted
ipcRenderer.on('custom-event', (event, ...args) => {
  console.log(args)
})
```

| `sendToHost(channel, ...args)`             | Send to webview host                                 |

### With Custom IpcRenderer

If `nodeIntegration` is disabled, you can pass the `ipcRenderer` instance explicitly:

```ts
import { useIpcRenderer } from '@vueuse/electron'
import { ipcRenderer } from 'electron'

const ipc = useIpcRenderer(ipcRenderer)
```
