What are GraphQL enums and how do I use them?

GraphQL enums are a special type of scalar that allows you to define a set of allowed values for a field. They are useful for representing a fixed set of options.

Can you give me an example of how to define an enum in a GraphQL schema?

Sure! Here's an example:

enum Color {
  RED
  GREEN
  BLUE
}

This defines an enum called Color with three possible values.

How do I use this enum in a query?

You can use the enum in your queries like this:

query {
  getColor(color: RED) {
    name
  }
}

This query requests a color with the value RED.

Are there any best practices for using enums in GraphQL?

Yes, it's best to keep your enums concise and meaningful. Avoid adding too many values, and ensure they are relevant to your domain.
