Basics about GraphQL Server

Schemas
TypeDefs
Resolvers

Schemas and TypeDefs

GraphQL requires you to design a schema which in turn defines the API of your server. GraphQL has its own type language that’s used the write GraphQL schemas: The Schema Definition Language (SDL). In its simplest form, GraphQL SDL can be used to define types looking like this:

type User {
  id: ID!
  name: String
}

There are 3 basic types called root types. Query, Mutation, and Subscription. These define the entry points of the GraphQL API.

Resolvers

The resolver act as the actual implementation of the GraphQL Schema. GraphQL has a clear separation of structure and behaviour. The structure of a GraphQL server is its schema, an abstract description of the server’s capabilities. This structure comes to life with a concrete implementation that determines the server’s behaviour. Key components for the implementation are so-called resolver functions. Below is and example of a resolver.

Query: {
  info: () => `This is the API`,
  feed: (root, args, context, info) => {
    return info
  },
}
