# Does DDD Belong on the Frontend? - Domain-Driven Design w/ TypeScript

**[Khalil Stemmler](https://daily.dev/sources/khalilstemmler)** · 18 min read · 0 upvotes · 0 comments

## Summary

An exploration of whether Domain-Driven Design (DDD) belongs on the frontend. The original 2019 post argues against it — business logic should stay on the backend due to single-source-of-truth constraints, frontend volatility, and the Open-Closed Principle. The real frontend challenge is maintaining consistent architecture around the chosen tech stack. However, some DDD concepts do apply: packaging by subdomain (screaming architecture), value objects for validation, DTOs as client-side models, and domain events via websockets. A 2020 update from the author reverses the original conclusion, affirming that DDD principles do belong on the frontend, with proper layer separation enabling testable, scalable frontend architecture.
