UC – GraphQL

In a previous Upskill Challenge, Katie Paxton-Fear took less than 30 minutes to introduce you to the basics of APIs and the most common API types you’ll see on the web including GraphQL, RESTful, gRPC, SOAP and web socket APIs. This time she focuses on one of those type… GraphQL.

GraphQL is an API type that offers an alternative approach to API design than the more typical RESTful APIs. It combines the ease of use and ease of sharing APIs of REST. But it does this without the same API sprawl and while adding flexibility for developers when consuming these APIs. Dig in to find out more!

What’s an Upskill Challenge (UC)?

A UC is a CTF-style, bite-sized lesson from the JHT Team, our courseware developers as well as “friends” of JHT. They are meant to be short and to the point. UCs focus on a single tool or concept and are helpful in quickly providing useful skills that might be prerequisites for other types of educational content on the platform.

A UC should be 10 – 30 minutes of student time and have no VMs. There are quizzes to make sure that the content is understood.

Prerequisites for “UC – GraphQL”

UCs assume no knowledge at all! They’re meant to be completely self-contained, so all of the answers are in the lesson. No outside research is required.
