Angular Signal Forms: Build Modern Forms with Signals

Build real Angular forms using Signal Forms: validation, async checks, dynamic fields, custom controls, and submission

What you’ll learn
Build modern Angular forms using the Signal Forms API
Implement validation using built-in, custom, and cross-field validators
Add async validation and debounce server checks
Create dynamic forms with conditional fields and repeatable sections
Build custom Angular form controls without ControlValueAccessor
Handle form submission, loading states, and server errors

Requirements
Basic knowledge of Angular and TypeScript
Familiarity with Angular components and templates
Angular CLI installed for running demo projects
A code editor such as VS Code

Description
Angular Signal Forms introduce a completely new way to build forms in Angular. Instead of managing complex FormGroup and FormControl trees, Signal Forms let you describe your form as data and allow Angular to derive the rest of the form state automatically.

In this course, you’ll learn how to build real forms using Angular’s new Signal Forms API from the ground up.

We’ll start by creating a simple form and understanding the core mental model behind Signal Forms. From there, we’ll progressively add powerful features like validation, async validation, dynamic fields, reusable form controls, and production-ready submission patterns.

By the end of the course, you’ll understand how Signal Forms work internally and how to confidently use them in your own Angular applications.

What you’ll learn

• Build forms using Angular Signal Forms
• Apply built-in validators like required, email, and minLength
• Create custom and cross-field validation logic
• Implement async validation with server requests
• Dynamically enable, disable, hide, or modify fields
• Create repeatable form sections using applyEach
• Build reusable custom form controls using FormValueControl
• Implement the Signal Forms submission lifecycle
• Map server-side validation errors back into your form

Who this course is for

Frontend developers looking to modernize their Angular form architecture
Angular developers curious about replacing Reactive Forms with signals
Developers building real-world Angular applications with dynamic forms and validation
