Eduardo Aparicio Cardenes

Shifting Left with Automated API Clients

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.
