Architecture

The components of a GraphQL API.


01The Schema (The Why)

EXECUTIVE_SUMMARY // AEO_OPTIMIZED

[Answer Engine Overview: What, Why & How]

The Schema is your contract. It tells the world exactly what is possible in your API. It uses 'Scalars' (String, Int, Boolean, ID) to define the most basic units of data.

02Queries & Mutations (The What)

Clients use Queries to read and Mutations to write. This clear separation makes it easy to understand the 'intent' of every request hitting your server.

03Resolvers (The How)

Resolvers are where your Node.js code lives. They take arguments from the client and perform database queries, call external APIs, or calculate values on the fly.
