### setMemberMeta

* **setMemberMeta**(`params`): `Promise<void>`

Assigns custom metadata to the specified [`RoomSessionMember`][roomsessionmember-28]. 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 the specified member.

#### Parameters

<ParamField path="params" type="object" required>
  Object containing the parameters of the method.
</ParamField>

<Indent>
  <ParamField path="memberId" type="string">
    ID of the member to affect.
  </ParamField>

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

#### Returns

`Promise<void>`

#### Example

In this example, we set metadata for a member as soon as they join the room.
Once the member's metadata is set, we log the metadata for that member with
the `onMemberUpdated` event.
This example assumes that there is a [`RoomSession`][roomsession-41]
already active and that members are joining the room.

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

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

// Access 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);

    roomsession.listen({
      onMemberJoined: async (member) => {
        console.log("Member joined", member.name);
        // set metadta for the member
        await roomsession.setMemberMeta({
          memberId: member.id,
          meta: {
            name: member.name,
            foo: "bar",
          },
        });
        // get member meta
        const memberMeta = await roomsession.getMemberMeta({
          memberId: member.id
        });
        console.log("Member meta", memberMeta.meta);
      },
    })
  }
})
```
