### setMeta

* **setMeta**(`meta`): `Promise<void>`

Assigns custom metadata to the RoomSession. You can use this to store metadata whose meaning is entirely defined by your application.

Note that calling this method overwrites any metadata that had been previously set on this RoomSession.

#### Parameters

<ParamField path="meta" type="Record<string, unknown>" required>
  The metadata object to assign to the RoomSession.
</ParamField>

#### Returns

`Promise<void>`

#### Example

In this example, we set metadata for a room as soon as it starts and then
log the metadata for that room. This example assumes that there is a
[`RoomSession`][roomsession-41] already active and
that members are joining the room.

```javascript
import { SignalWire } from "@signalwire/realtime-api";

// Initialize the SignalWire client
const client = await SignalWire({ project: "ProjectID Here", token: "Token Here" })

// Access the video client from the main client
const videoClient = client.video;

// Setup listener for when a room starts
await videoClient.listen({
  onRoomStarted: async (roomSession) => {
    console.log("Room started", roomSession.displayName);

    // Set the room meta
    console.log("Setting room meta");
    await roomSession.setMeta({
      "foo": "bar",
      "roomName": roomSession.displayName
    });

    // Get the room meta
    let roomMeta = await roomSession.getMeta()
    console.log("Room meta", roomMeta);
  },
  onRoomEnded: async (roomSession) => {
    console.log("Room ended", roomSession.displayName);
  }
});
```
