Description: A type subscription in GraphQL allows clients to subscribe to real-time updates of a specific type. Unlike queries and mutations, which are one-off operations, subscriptions are designed to maintain an active connection between the client and the server. This means that when a change occurs in the data corresponding to a specific type, the server can automatically send updates to all clients subscribed to that type. This feature is particularly useful in applications that require interactivity and instant updates, such as collaborative applications, data monitoring tools, or live streaming platforms. Subscriptions are typically implemented using WebSockets, allowing for efficient bidirectional communication. In summary, type subscriptions in GraphQL are a powerful tool for building modern applications that need to reflect real-time changes, enhancing the user experience by providing updated information without the need to reload the page or make repeated queries.
