Detailed explanation-1: -What is Offline Mode? Offline mode is a feature that allows users to access mobile apps without the Internet. The feature is being used in many apps such as Amazon Kindle, Uber, and Google Maps. Offline mode limits a user’s inconvenience when the internet connection is lost or intermittent.
Detailed explanation-2: -Cloud Firestore supports offline data persistence. This feature caches a copy of the Cloud Firestore data that your app is actively using, so your app can access the data when the device is offline. You can write, read, listen to, and query the cached data.
Detailed explanation-3: -The Firebase Realtime Database stores data returned from a query for use when offline. For queries constructed while offline, the Firebase Realtime Database continues to work for previously loaded data. If the requested data hasn’t loaded, the Firebase Realtime Database loads data from the local cache.
Detailed explanation-4: -Assume that you downloaded the records your master sync is completed and you goes offline at 1:00 pm and come back online at 9:00 pm. During the offline hours you updated the records locally in your mobile and now when you go online these records will be pushed online to your data base.
Detailed explanation-5: -In an offline app, the app or device downloads the data from the server. It then stores it securely and locally. Some databases, like CouchDB Lite, SQL Lite, enable storing app data locally on the device. Also, if the app users need real-time information, you need a local database that will house all the data.
