## Notes
|
|
|
|
- Removing subscriptions is a great way to maintain the performance of your project's database. Supabase will automatically handle cleanup 30 seconds after a user is disconnected, but unused subscriptions may cause degradation as more users are simultaneously subscribed.
|
|
|
|
## Examples
|
|
|
|
### Remove a subscription
|
|
|
|
```js
|
|
supabase.removeChannel(mySubscription)
|
|
```
