If we use REST API to fetch the details of employees and their companies, we have to make two requests to the server like /api/v1/employees and /api/v1/companies. ASP.NET Core is an open-source framework for building web apps and web APIs.

Using GraphQL, you can discover the schema in the appropriate format. In this case, when the data gets more complex, the routes get longer. In this tutorial, we are going to be expanding upon the work we did in our previous GraphQL Go tutorial and looking at mutations and implementing proper data-sources behind our GraphQL API. Node modules are not included in the course files. Now, GraphQL is used by a lot of companies such as Facebook, Github, Twitter, Coursera, yelp, Pinterest, Serverless, ProductHunt, Shopify, etc. JavaTpoint offers too many high quality services. GraphQL is constantly and rapidly growing its community because a large number of companies like Netflix and Coursera are interested and working on similar ideas to make this API more efficient. But if you use GraphQL, the mobile application can fetch details for both Employee and Company objects in a single request. We assure that you will not find any problem in this GraphQL tutorial. Now, we have to create a mobile application to fetch only the firstName and id. GraphQL is a query language for your API, and a server-side runtime for executing queries by using a type system you define for your data. Duration: 1 week to 2 week. It is cross-platform, runs on .NET Core , and can be hosted on-premise or cloud-based. GraphQL is a query language for your API, and a server-side runtime for executing queries by using a type system you define for your data. Then we need some IDE/Editor in order to do some proper C# coding, you can use VSCode or if you have already on your system Visual Studio or JetBrains Rider. There, search for two dependencies: 1.

GraphQL is an open source server-side technology which was developed by Facebook to optimize RESTful API calls. It is also an execution engine that works as a data query language and used to fetch declarative data. The results of GraphQL are always predictable. It executes queries by using type systems which we define for our data. Applications run faster because compact queries return small responses without unnecessary data and developers are more productive because of GraphQL's self-documenting nature. Sometimes, it is challenging to fetch the data with a single request. In this document we will see what’s GraphQL, what it solves, how to build a simple GraphQL back-end for our ASP.NET Core project and also how to consume this GraphQL. This data is accessed using a so-called field in GraphQL.
