GraphQL is a query language for API and a server-side runtime for executing queries using a type system you define for your data. A GraphQL service is created by defining types and fields on those types, then providing functions for each field on each type. It makes easier to evolve APIs over time.
GraphQL APIs are organized in terms of types and fields, not endpoints. GraphQL uses types to ensure Apps only ask for what’s possible and provide clear and helpful errors. Apps can use types to avoid writing manual parsing code. GraphQL enables declarative data fetching in order to give the client the power to specify exactly the data that is needed from the API.
Rest is an architectural style for designing web services. . It is designed for working with media components, files, or hardware devices. REST(“Representational State Transfer”).
Advantages of GraphQL
. Fetch data with a single API call.
. Provides a human-readable query.
.Queries can be executed within the context of a particular system.
.Encourage cleaner, more maintainable server code.
.Enables declarative data fetching.
Conclusion
GraphQL is really faster than REST. Also, GraphQL is the future of APIs.
