The key to building mobile and edge apps that can operate without internet connectivity is to adopt an "offline first" mindset, which assumes network connectivity issues will occur and develops around them. This approach requires designing the app's data storage and processing to be independent of internet connections, using a database that can store and process data locally on the device. A key player in this space is Couchbase, a mobile database that provides a developer-friendly solution for offline first apps, including its embedded NoSQL mobile database, Couchbase Lite, and fully managed cloud DBaaS, Capella App Services. By leveraging Couchbase's capabilities, developers can build fast and available apps that meet the requirements of high-speed applications with no tolerance for latency or outages.
