Design APIs Using GraphQL
Learn how to design API using GraphQL API.
Making a good API design is a challenging task that rewards iteration, experimentation, and a thorough understanding of the business domain. For this lesson, let’s imagine that we work at a next-generation pizza company. We have an existing GraphQL API for an existing feature for the current business model. We now want to introduce a new feature. On the backend, the new feature requires the following implementations:
- All pizzas must have essential attributes like
pizza
anddescription
that indicate whichtopping
orsauce
they will be served with. - Some types of pizza must have customizable unique attributes. For example, we should be able to customize the
sauce
in a Neapolitan pizza and thecrust
in a St. Louis pizza.
With these requirement fulfilled, we can start thinking about the API design we’ll use to introduce the new feature.
