Building with Signal Forms: Basic Implementation and Validation

In the previous chapter, we got a conceptual overview of Signal Forms. Now, it’s time to put theory into practice. We’ll set up a simple user registration form using Signal Forms, focusing on field binding and basic validation.

Prerequisite: Ensure you have an Angular v21 project set up (e.g., using ng new your-app --standalone).

Step 1: Install Experimental Signal Forms Package

Since Signal Forms are experimental, they reside in a separate package (or subpath). You might need to install it explicitly or ensure your @angular/forms version includes it.
