What are Offline-First Databases for Firebase?

Offline-first databases are systems designed to prioritize local data storage and enable applications to function seamlessly even when there is no internet connection. These databases store data on the device itself, allowing users to access, modify, and interact with their data offline. When the device reconnects to the internet, the database syncs with the remote server, ensuring that any changes made offline are reflected in the cloud or central database. Offline-first databases are ideal for mobile applications, remote work environments, or any scenario where constant internet access is unreliable. By using these databases, developers can ensure that users have a consistent and uninterrupted experience, regardless of connectivity.
