How many times have you opened an app and stared at a loading screen for minutes, only to be confronted with an unpleasant message, “No internet connection”? or even more frustating is when you fill a long form, only to submit and get a message “Cannot be submitted right now, please try again”. Most mobile applications are simply clients that display data received from a server in real time, losing all functionality without an internet connection. How great would it be, if an app worked regardless of network connectivity?
Why offline ?
The Mobile phone network in India though claims to have 4G but in reality the reliability and speed of the network is yet to reach and span whole India. Even in metro cities the continuity of the network is not perfect. In such scenarios it becomes a technical challenge for the engineering teams to come up with solution that allows app users to use the app without worrying about network signal strength or availability.
The offline feature is more challenging in data driven apps because a user has multiple end points through which his data can be changed leading to conflicts. Keeping all of it in sync and maintaining the integrity of data is must.
In this session we will learn
How data driven applications can work offline using local data and a seamless sync strategy. Strategies to resolve sync conflicts. Best practices while empowering your app to be offline.
