GraphQL Subscriptions
GraphQL Subscriptions are a feature of GraphQL that enables real-time data updates from a server to clients over a persistent connection, typically using WebSockets. They allow clients to subscribe to specific events or data changes and receive push notifications when those events occur, facilitating live data synchronization in applications. This is particularly useful for features like chat applications, live notifications, or collaborative editing where immediate data updates are required.
Developers should use GraphQL Subscriptions when building applications that require real-time functionality, such as messaging apps, live dashboards, or multiplayer games, to avoid inefficient polling and reduce latency. They are essential in scenarios where data changes frequently and clients need instant updates without manual refreshes, enhancing user experience and system efficiency. This is especially valuable in modern web and mobile apps where real-time interactivity is a key requirement.
