Self-hosted GraphQL refers to the ability to host and run a GraphQL server within your own infrastructure or application. It provides developers with the flexibility to have full control over the GraphQL server and its deployment.One of the key advantages of self-hosted GraphQL is the ability to integrate it seamlessly with existing systems and services. By hosting the GraphQL server within your own infrastructure, you can easily connect it to your databases, microservices, or any other data sources that your application relies on. This allows for efficient data fetching and manipulation, as well as the ability to leverage existing authentication and authorization mechanisms.Another benefit of self-hosted GraphQL is the ability to customize and extend the server to meet specific requirements. You have the freedom to define your own resolvers, data models, and business logic, giving you full control over how your GraphQL API behaves. This level of customization can be particularly useful when working with complex data structures or when integrating with legacy systems.Additionally, self-hosted GraphQL provides better performance and scalability compared to using third-party GraphQL services. By hosting the server within your own infrastructure, you can optimize it for your specific use case and scale it according to your application's needs.
