Creating GraphQL APIs with ASP.Net Core for Beginners

GraphQL is a language for APIs that enables you to query and manipulate data easily through an intuitive and flexible syntax.

GraphQL is an open-source data query and manipulation language for APIs.

GraphQL was developed internally by Facebook in 2012 before being publicly released in 2015.

It is used in many server-side languages like Java, Node, Ruby, Python, PHP, Go, and obviously dotnet too. And APIs created using GraphQL can be easily accessible by almost all languages, like JavaScript, Android, Swift, Python, PHP, Java, and dotnet.

In a GraphQL request, you specify how to structure the data when it’s returned by the server. This makes it possible for you to query only the data you need, in the format you need. This results in better network utilization and performance, especially on mobile devices.

The course outline includes:

• Introduction to GraphQL. And understood how it’s different from RESTful APIs.

• Create basic GraphQL queries. As well as with arguments and aliases.
