GraphQL does not natively support offline usage. However, there are several tools and libraries that can enable offline-first capabilities when using GraphQL. These tools typically rely on caching mechanisms and service workers to handle data operations while offline.
Key Points:
Native Support:
GraphQL itself does not provide built-in support for offline usage[1].
GraphQL Clients:
Various GraphQL clients, such as Apollo Client, can be configured to work offline by using caching strategies. These clients store data locally and synchronize with the server when a connection is re-established[1][2].
Offix is another tool that extends Apollo GraphQL to support offline experiences, including features like offline listeners, conflict resolution, and multi-platform support[4].
Implementation Examples:
Apollo Client: Requires custom optimistic update logic and cache management to handle offline scenarios[2].
Back4App with Flutter: Uses shared preferences for offline data persistence, allowing the app to fetch data from the cache when offline[3].
RxDB with Hasura: Utilizes a local database to store and sync data, ensuring the app remains functional without a network connection[6].
Apollo-Offline: Provides a custom network interface and Redux store enhancer to enable offline-first app development using Apollo GraphQL[7].
