取消订阅多个 Firestore 快照 VueJS

Question

What is the right way to unsubscribe to multiple snapshots in vuejs?

I have multiple components, and most of them have a snapshot to take advantage of firebase real time sync, the logout function is located in a navbar component, but once I logout from firebase, I got an error because I'm not unsubscribing from my snapshots, but how can I do this if all of them are on different components?

Is there a way to unsubscribe all snapshots at once?

Thanks in advance for your kind help.

To unsubscribe from a snapShot, you can use beforeDestroy . This gets called whenever you navigate away from this component. Inside you can call methods for unsubscribing from your snapShots.

For more information, see the Vue.js docs. https://v2.vuejs.org/v2/api/#beforeDestroy
