🗣️ Talks:
➡️ Shifting Left with Automated API Clients by Eduardo Aparicio Cardenes
API contracts are the backbone of modern frontend-backend collaboration, but manual integration slows teams down and increases errors. What if we could automate it?
In this talk, we’ll dive into Shift Left API contract development and introduce an approach to automatically generate an NPM package from API contracts. This package provides:
✅ TypeScript types for strict FE & BE consistency
✅ Zod validation for safer forms and API responses
✅ Axios + React Query for streamlined fetching & caching
✅ Automated versioning & observability to ensure API integrity
By shifting API validation, testing, and integration earlier in development, teams can move faster, reduce errors, and improve efficiency. Whether you're a developer, tech lead, or architect, this session will give you practical strategies to automate your API workflows and accelerate your development pipeline.
➡️ Server vs. Client: Are We Optimizing for Code or Use - Alex Holmes
The options for front end web development in 2025 are expansive, offering powerful features to consider, like utilising client or server components, and diverse data fetching strategies. Yet, with so many options, it is easy to become overly focused on the architectural approach and risk losing sight of our fundamental goal - user experience. This talk examines the potential downsides of prioritising one architectural approach over another - or prioritising any at all - and poses the question: as we build with these modern frameworks, should the guiding principle be the approach we take, or the quality of the user experience we deliver?➡️ Synced Reactive State: Build React Apps Without Backends by Anselm Eickhoff
Jazz is a framework for building React apps without a backend. It takes the familiar idea of reactive state and adds real-time sync to the cloud and other users. You can set precise edit permissions on each bit of state right from the client as well, which means that basically all business logic now lives next to your UI. In this talk, we'll see what this looks like in practice by building a multi-user app that also works offline and across devices -- in no time.
