Worked on enhancing the reliability of Relay subscriptions within the facebook/relay repository by introducing an onPause callback in the cacheConfig. This feature was designed to handle scenarios where live query streams are paused due to network interruptions, allowing for more graceful management of subscription states and reducing the risk of stale data for consumers. The implementation focused on improving the robustness of data fetching mechanisms in JavaScript-based front end environments, leveraging skills in React and Relay. By addressing the subscription lifecycle during connectivity issues, the work laid a foundation for more resilient real-time data handling across diverse deployment environments.
