Angular's Signal Forms combine signals with a model-first approach to radically simplify how we build forms, track form state, and validate user input. Instead of wiring validation to UI controls, Signal Forms move the logic where it belongs: into a strongly typed form model.

In this session, we’ll break down how Signal Forms work. You'll see how signals drive state to dramatically reduce boilerplate code. We'll explore powerful validation patterns, including conditional, pattern, and custom validation. And you'll see how this approach makes forms easier to reason about and maintain.

You will leave with practical techniques you can apply immediately to modern Angular applications.

You will learn:

  • Understand the core architecture of Angular Signal Forms and how signals drive form state
  • Implement validation patterns including conditional and custom validation
  • Display and manage validation errors effectively
