Every GraphQL server has two core parts that determine how it works: a schema and resolve functions.
The schema is a model of the data that can be fetched through the GraphQL server. It defines what queries clients are allowed to make, what types of data can be fetched from the server, and what the relationships between these types are.
Consider:
type Author {
id: Int
name: String
posts: [Post]
}
type Post {
id: Int
title: String
text: String
author: Author
}
type Query {
getAuthor(id: Int): Author
getPostsByTitle(titleContains: String): [Post]
}
schema {
query: Query
}
