Adding descriptions
One of the great features of a schema-backed API is that it is self-documenting. Many API developers choose to maximise the benefit of this by adding descriptions to some or all of the components of their schema.
The trade-off for using descriptions is that the YAML configuration becomes a bit more verbose.
Let's add some descriptions to our types and fields.
app/_graphql/schema.yml
types:
Country:
description: A record that describes one of the world's sovereign nations
fields:
code:
type: String!
description: The unique two-letter country code
name:
type: String!
description: The canonical name of the country, in English
We can also add descriptions to our query arguments. We'll have to remove the inline argument definition to do that.
app/_graphql/schema.yml
queries:
readCountries:
type: '[Country]'
description: Get all the countries in the world
args:
limit:
type: Int = 20
description: The limit that is applied to the result set
