### subscribe

* **subscribe**(`channels`): `Promise<void>`

List of channels for which you want to receive messages.

Note that the `subscribe` function is idempotent, and calling it again with a different set of channels *will not* unsubscribe you from the old ones. To unsubscribe, use [unsubscribe][link-2].

#### Parameters

| Name       | Type                   | Description                                                                                            |
| :--------- | :--------------------- | :----------------------------------------------------------------------------------------------------- |
| `channels` | `string` \| `string[]` | The channels to subscribe to, either in the form of a string (for one channel) or an array of strings. |

#### Returns

`Promise<void>`

#### Example

```js
const chatClient = new Chat.Client({
  project: "<project-id>",
  token: "<api-token>",
});

chatClient.on("message", (m) => console.log(m));

await chatClient.subscribe("my-channel");
await chatClient.subscribe(["chan-2", "chan-3"]);
```
