如何在 JavaScript SDK 中的 Firebase Firestore 中仅缓存选定的文档

Question

I'm making a chat app and I want Firebase Firestore database to cache only that messages which are sent by me or for me. How can I do this? Can I control what documents are cached in Firestore database? Thanks.

The Firestore SDK provides no direct control over the cache, other than its total size, and whether or not it's active. The documentation describes everything you can do.

One alternative is to only use the SDK to read documents that should be cached, and use the REST API for all other reads that should not be cached.
