19:30: State of confusion: the hidden impact of neglecting server state
Speaker: Breno Oliveira

State management in React is often reduced to handling local and global state, leaving server state overlooked.

This talk explores the unique challenges of managing server state —staleness, synchronization, and complexity —and how ignoring it can lead to redundant, inconsistent application states. Understanding server state as a critical part of your application helps you simplify workflows, maintain consistency, and build more robust applications.

20:00: Revolutionizing Form Building with Formity: Advanced Multi-Step Forms in React
Speaker: Martí Serra Molina

In this talk, we will dive into Formity, an open-source npm package designed to streamline the creation of advanced multi-step forms in React. Formity makes it easy to build forms where each step dynamically adapts based on the user's previous answers. Creating such forms with complex conditional logic can be a time-consuming and error-prone task, often resulting in tangled and unmanageable code.

We’ll explore how Formity simplifies this process by providing an intuitive framework that keeps your code clean and maintainable, even for the most intricate workflows. Through real-world examples, we’ll demonstrate how Formity enables developers to tackle the challenges of multi-step forms with ease, helping you save development time while delivering a seamless user experience. Whether you’re building interactive surveys, onboarding flows, or complex data collection tools, this talk will show you how Formity can elevate your form-building game.

20:30: Drinks and networking!
