Sviluppare una app Angular da zero con i Signal
In questo workshop di 2 ore partiremo da zero per creare un’app Angular moderna sfruttando le nuove Signal API, pensate per migliorare performance e gestione dello stato.
Dimentichiamoci Zone.js e scopriamo insieme Signals, il nuovo Control Flow e tante altre API che stanno rivoluzionando Angular!
Sarà un mix di teoria e pratica, con tanto codice, esempi reali e consigli per scrivere componenti più flessibili ed efficienti.
Cosa imparerai?
✅ Come funziona il nuovo sistema di reattività basato sui Signals
✅ Come creare, leggere e aggiornare uno Signal
✅ Come usare i Computed Signal ed Effects
✅ Come gestire lo stato di una app usando Signals
✅ Come scrivere template più chiari con il nuovo Control Flow (@if, @for, @switch)
✅ Best practice per scrivere componenti più semplici, reattivi ed efficienti
Il workshop sarà ricco di hands-on, con esercizi pratici per mettere subito in pratica ciò che impari.
Non perdere l’occasione di portare le tue skill Angular al livello successivo! 🎯
Kneel before Zod - Enhance the safety of your Angular App!
We'll explore the fundamentals of type checking — how TypeScript handles it, and where its limitations lie.
We'll then introduce Zod, a powerful library that brings runtime validation to your TypeScript types, helping you catch issues that static typing alone can't cover.
By the end of the session, you'll be ready to integrate Zod into your codebase and ensure that changes in backend responses no longer catch you off guard.

Dependency Injection and the Order of Micro-Frontends
When it comes to Angular, Dependency Injection is one of its most underrated superpowers, but what happens when multiple Angular apps need to live on the same page?
In this talk, we’ll start from the basics of Angular's DI to understand how it works, how it helps reduce complexity — and how it can turn into a trap when misused in distributed scenarios.
We’ll walk through a practical pattern for sharing services and state across multiple Angular apps, while keeping full isolation in local environments.
All of this using Angular’s native features, no external libraries, and the power of resolution modifiers. 🎁
What you’ll walk away with:
- A solid understanding of how Dependency Injection works in Angular
- The core principles (and pitfalls) of micro-frontend architecture
- A practical and scalable approach to share state and services across multiple Angular MF apps.
Good Things Come to Those Who @defer
Performance and user experience are essential in modern web development — and Angular’s @defer directive is changing the way we think about rendering.
In this talk, we’ll explore the powerful combination of Deferrable Views and Incremental Hydration, introduced in Angular v19, and how they can help you deliver faster, smarter applications.
You’ll learn how to:
- Understand the differences between CSR, SSR, and SSG — and when to use each
- Optimize content loading using @defer and its powerful trigger system
- Use Incremental Hydration to deliver seamless interactivity for SSR apps
- Avoid common pitfalls and follow best practices to improve performance
This session provides practical insights to boost both developer experience and runtime efficiency.
