![]() I've also incorporated developer insights and feedback from Rajoshi Ghosh, co-founder of Hasura.io, Praveen Durairaju, a senior developer advocate at Hasura.io, and Joel Myers, a senior software engineer at Red Hat. In addition, I've included individual contributions from Zach Lendon, director of application development at AIM Consulting and co-author of this article. This article will explain some of the benefits of using GraphQL, including some tradeoffs and a few use cases from Netflix and Facebook. Streamlining DevOps in hybrid, multi-cloud, on-premises, and edge environments.However popular, the open source technology created by Facebook in 2012 should not be thought of as a replacement for REST but as a welcome alternative. While GraphQL is not perfect, its popularity is rising, and it's gaining more traction for a reason. But as times have changed, so has the way data is managed-and along came GraphQL. RESTful API design set the stage for stateless servers, better access to resources, and more efficient data retrieval. Then came representational state transfer (REST), an architectural style coined by Roy Fielding in his PhD dissertation in 2000. Once upon a time, Simple Object Access Protocol (SOAP), the process of sending and receiving messages from one application to another using HTTP, was the standard for data transmission. API design is, in fact, far more complex than it used to be. But there are a few factors to consider when choosing the best method for moving information across systems. What works for one organization's needs may not serve another's needs in the same way. It will either retrieve data from connected database or from the integrated API’s.There is no right kind of architecture for data exchange. In this architecture, the GraphQL server will resolve any request that is received. Hybrid Approachįinally, we can combine the above two approaches and build a GraphQL server. Client applications communicate with the GraphQL server which in turn resolves the query. In the above diagram, a GraphQL API acts as an interface between the client and the existing systems. GraphQL can be used to unify microservices, legacy infrastructure and third-party APIs in the existing system. This approach is helpful for companies which have legacy infrastructure and different APIs. GraphQL Server Integrating Existing Systems ![]() The server processes the request, fetches data from the database and returns it to the client. The client (desktop/mobile) communicates with GraphQL server over HTTP. In the above diagram, GraphQL server and the database are integrated on a single node. The response returned to the client adheres to the format specified in the official GraphQL specification. On the receipt of a Query, the server reads the request payload and fetches data from the database. This architecture has a GraphQL Server with an integrated database and can often be used with new projects. GraphQL server that integrates existing systems.GraphQL Server can be deployed by using any of the three methods listed below − ![]() It is also neutral to databases, so you can use it with relational or NoSQL databases. It can be used with any available network protocol like TCP, websocket or any other transport layer protocol. ![]() Another important concept of GraphQL is its transport layer agnostics. The request made by a client to the GraphQL server is called a Query. It is a set of guidelines on how requests and responses should be handled like supported protocols, format of the data that can be accepted by the server, format of the response returned by the server, etc. GraphQL is a specification that describes the behavior of a GraphQL server.
