# Domain-Driven GraphQL Schema Design using Event Storming

**[Khalil Stemmler](https://daily.dev/sources/khalilstemmler)** · 7 min read · 0 upvotes · 0 comments

## Summary

A walkthrough of using Event Storming — a collaborative DDD workshop technique — to design a GraphQL schema. The process involves six steps: identifying domain events as past-tense verbs, deriving GraphQL mutations from commands, grouping them under aggregates, enforcing bounded context boundaries to define top-level fields (for monoliths or federated microservices), identifying views/queries per aggregate, and finally writing the schema. The approach emphasizes involving both domain experts and developers to build a shared understanding, avoiding costly schema mistakes. Includes a concrete schema example from a Hackernews-like app (DDDForum).
