HATEOAS: Hidden Architecture That Enables Outstanding App Simplicity

This talk revisits the foundational principles of REST as originally defined by Roy Fielding, with a specific focus on HATEOAS (Hypermedia as the Engine of Application State).

We'll examine how modern web architecture drifted away from this constraint and why it's time to reintroduce hypermedia-driven approach into our application design. By outlining the practical advantages of HATEOAS, we’ll make the case for its relevance today.

We'll look at how real-world projects like HTMX, Data-star and Hotwire Turbo are using hypermedia into action, and introducing Vyper, a meta-framework for building hypermedia-driven web applications in Go that I'm currently working on, which is rooted from my earlier project VStack, which aims to simplify frontend-development for Go developers.

Agenda:

• REST and HATEOAS: The Original Vision

  • Clarifying the architecture Roy Fielding defined, especially the overlooked HATEOAS constraint.

• Why Hypermedia-driven approach?

  • The growing need for self-descriptive APIs and dynamic interaction models in distributed systems.

• Needs, Merits & Use-cases of HATEOAS

  • Practical benefits: better evolvability, reduced coupling, and more maintainable APIs over time.

  • Also the use-cases and scenarios under which HATEOAS principle shine and really helpful.

• Modern Implementations

  • Case studies of htmx, Data-star, Unpoly, Hotwire Turbo and similar projects that show HATEOAS working in real applications.

• Introducing Vyper

  • Overview of a Go-based meta-framework for building hypermedia-first apps, emphasizing developer simplicity.

• Understanding REST for real: What Roy Fielding actually meant by REST — beyond just JSON over HTTP.

• HATEOAS clarified: How hypermedia drives application state and why it matters for long-term API health.

• Needs & Merits of hypermedia-driven design approach

• HATEOAS in action: A look at tools like HTMX, Data-star and how they implement hypermedia patterns in practical, lightweight ways.

• Vision for Go web dev: How Vyper aims to reshape frontend/backend responsibilities and bring back simplicity and power to Go-based web development.
