7 years ago - Using the Ionic's ion-img directive for improving performance with images
- Using Ionic's infinite scroll for long lists
- Looking at optimising change detection all over the place, using OnPush more and removing reliance of expensive observables being unnecessarily resubscribed to by the async pipe etc.
- Caching data locally with Ionic Storage - https://ionicframework.com/docs/storage/ - chats would be a very good candidate for this, then managing updates to the local storage by querying with the objectId of the last message and then returning all messages from that ID
- Implementing lazy loading everywhere!
