Applications using GraphQL are fast and stable because they fetch the data for required fields only, unlike the REST APIs, where REST APIs fetch data for all the fields for a specific object. GraphQL isn’t tied to any specific language or a database, just the opposite, it is adaptable to our code and our data as well. GraphQL Tutorial. Proof #2 that GraphQL is an integral part of web development: its adoption by tech giants. You don't face over fetching and under fetching issues in GraphQL. Applications run faster because compact queries return small responses without unnecessary data and developers are more productive because of GraphQL's self-documenting nature.

The viewer object can be used to request data about the currently authorized user. It was developed to optimize RESTful API calls and provides a flexible, robust, and more efficient alternative to REST. The viewer is an object in GraphQL terms.

GraphQL provides a complete and understandable description of the data in your API, gives clients the power to ask for exactly what they need and nothing more, makes it easier to evolve APIs over time, and enables powerful developer tools.
