![]() GraphQL looks a bit special when you query it but it's quite simple. json-graphql-server is a testing and mocking tool for GraphQL that takes a JSON of your data. Some form of visual environment comes with most implementations of GraphQL. Then you have a visual environment called GraphiQL that allows you to run queries. A resolver is mapped to a certain resource. A resolver is simply a function that knows what to do with an incoming query. You can define that schema in something called GQL, GraphQL Query Language but you can also decorate classes to respond to certain resource requests (more on that one in future articles).īesides from the schema, there is a central concept called resolvers. On the backend, you can grab the data from different data sources so there definitely is a good reason to be excited, for frontend developers as well as backend developers. It also allows you to query for exactly the fields you want. GraphQL allows for content negotiation which means you will only have one endpoint. # WHY, why do we need it in the first place. ![]() If you want to have a look at how things are done in JavaScript have a look at these articles I wrote. How to build and consume GraphQL APIs in JavaScript It even covers how to build a Serverless API. It shows how to build different types of projects, run tests and more. I wrote a collection of articles for you that is curious about. It contains a README page that helps you get started but also demos for different types of applications like MVC for example. This is the most popular NuGet package there is. It contains a lot of information on why GraphQL was built, what types exist and so on. This is the website for the GraphQL organization. Demo, let's build an API and learn how we get that to work with our data sources.WHAT, what are the parts it consists of.WHY, why do we want this technology to build APIs from.It's a very cool piece of technology and it's not just for JavaScript, you can definitely use it for your next project in. It also enables the builder of the API to stitch together data from different APIs, should you wish it. GraphQL is this technology created by Facebook that enables the frontend to negotiate with the backend for what data it wants. To work properly, GraphQL queries need to be sent to a GraphQL service, which uses a document called a schema to understand the different types of data a user can read or update, and the fields that exist on. NET Core and C#įollow me on Twitter, happy to take your suggestions on topics or improvements /Chris GraphQL, which stands for Graph Query Language, is a language you can use to write efficient queries that read or change data.
