## Notes
|
|
|
|
- Removing a channel is a great way to maintain the performance of your project's Realtime service as well as your database if you're listening to Postgres changes. Supabase will automatically handle cleanup 30 seconds after a client is disconnected, but unused channels may cause degradation as more clients are simultaneously subscribed.
|
|
|
|
## Examples
|
|
|
|
### Remove a channel
|
|
|
|
```js
|
|
supabase.removeChannel(myChannel)
|
|
```
|
