Offline caching with AWS Amplify, Tanstack, AppSync and MongoDB Atlas
Front-End Web & Mobile Blog
This article demonstrates how to create an offline-first application using AWS Amplify, AWS AppSync, TanStack Query, and MongoDB Atlas. The key focus is on implementing an optimistic UI that provides a seamless user experience.
- Enables applications to work without an active internet connection
- Uses TanStack Query for asynchronous state management and offline caching
- Implements optimistic UI that updates the interface before server confirmation
- Provides a sample to-do application with conflict resolution mechanisms
- Leverages AWS services like Amplify, AppSync, Lambda, and Cognito
The solution simplifies offline data handling by allowing immediate UI updates and providing mechanisms to rollback changes if server requests fail, ultimately improving user experience and application performance.
