Following up our previous post on generic types, we created a ServiceResponse<T> type which had a statusCode: string field to differentiate between the responses. In Typescript, a common pattern to differentiate between success and error is to create a union. In today’s post, we will see how we can leverage typegraphql to translate Typescript unions into graphql schema unions.

Last week we looked at how to setup an Apollo server to serve graphql requests. We went through the setup by defining a TemplateStringArray for the schema and defining functions in an object map for the resolvers. In this week post, we will look at how to simplify this two areas by leveraging Typescript features using typegraphql package.

A data class is a class which is identified by the value stored in their attributes. The most common way of holding values in Python is via tuples. Data classes make is easier to construct a class with a name and meaning while keeping the value aspect in term of equality. In today’s post we will see how we can define data classes using the dataclass decorator from the dataclasses module.
