One column per quarter.
Added a memory-only firestore build. Instead of persisting data in the IndexedDB , it keeps it in memory. This build is about 14% smaller than the full featured build because it doesn't have IndexedDB related code. If you don't care about persisting data across sessions, or your code runs in environments that don't support IndexedDB , use this build to reduce your application size. It is available under a special import path. You can import it this way:
import * as firebase from 'firebase/app' ; import 'firebase/firestore/memory' ;
// Don't change the format for any other products. import 'firebase/auth' ; // etc.
Or if using the CDN:
< script src = "https://www.gstatic.com/firebasejs/7.13.0/firebase-app.js" >< / script > < script src = "https://www.gstatic.com/firebasejs/7.13.0/firebase-firestore.memory.js" >< / script > < !-- Don ' t change the format for any other products . -- > < script src = "https://www.gstatic.com/firebasejs/7.13.0/firebase-auth.js" >< / script > < !-- etc . -- >

firebase.setLogLevel() , which sets the level above which Firebase log messages will be shown.
Added two methods for logging:
firebase.setLogLevel() , which sets the level above which Firebase log messages will be shown.
firebase.onLog() , which adds a user-specified callback run on each log event. The callback has access to log level, message, and name of the package (e.g. "@firebase/firestore") that generated the log message.
