Course Description

This course is a complete guide to building complex, production-ready forms with the Angular Signal Forms API. It comes with a running GitHub repo.

This Course In a Nutshell

Angular Signal Forms is a ground-up redesign of the Angular Forms module, built entirely around signals. It replaces Observables and FormControl with a reactive, model-driven approach that is simpler to learn, easier to type, and far less boilerplate-heavy than both reactive and template-driven forms.

This course teaches Signal Forms from the ground up by building a sample application with login, profile, file upload, nested forms, multi-step forms, form arrays and more.

Every form pattern you'll encounter in a production application is covered, including async server validation, conditional fields, reusable custom controls, and multi-step wizards.

Course Overview

We start with a simple login form to introduce the core Signal Forms API and field state signals. We cover built-in validators, custom validation rules, and how to display error messages cleanly using a reusable error component.

We then build a profile form to explore field availability (readonly, dirty, reset) and introduce route guards that prevent accidental navigation away from unsaved changes.

Next, we go deep on custom form controls. We build a reusable address sub-form, and then a fully custom file upload control with a real HTTP upload, a progress bar, and a live image preview — all wired into the form system with no special handling required in the parent.

We cover the unique challenge of initializing a form from an Angular input signal, and why a plain signal is not enough here.

Async validation gets a dedicated section: we implement server-side field validation, add debouncing to reduce unnecessary API calls, and display a pending spinner while the server responds.

We then build a multi-step course creation wizard covering conditional fields, cross-field validation, dynamic lesson arrays, and multi-form coordination with a draft pre-save mechanism.

Table of Contents

This course covers the following topics:

  • Introduction — overview, why Signal Forms, setup

  • Form Model Design — designing the form model, form vs domain model, avoiding common pitfalls

  • Your First Form — form model, field binding, validation schema, error messages, form submission

  • Schema Libraries — integrating Zod and custom validation schemas via Standard Schema

  • Field State — read-only fields, unsaved changes, reset, navigation guard

  • Nested Custom Controls — reusable sub-forms as custom controls

  • File Upload Control — custom file upload with progress indicator and live preview

  • Forms from Inputs — initializing a form from a parent component input

  • Async Validation — loading remote data, server-side validation, debouncing

  • Conditional Forms — conditional fields, conditional schemas, cross-field validation

  • Form Arrays — dynamic lists with per-item validation schemas

  • Multi-Step Forms — coordinating multiple forms, final submission

  • Draft Pre-Saving — auto-saving form state, restoring a draft on page load

What Will You Learn In This Course?

By the end of this course you will be able to:

  • Build any type of form using Angular Signal Forms from scratch

  • Apply built-in and custom validators, including async server-side validation

  • Build reusable custom form controls that integrate seamlessly with the form system

  • Handle conditional fields, cross-field validation, and dynamic arrays

  • Integrate external schema libraries like Zod via validateStandardSchema

  • Implement production patterns: unsaved-changes guards, draft pre-saving, multi-step wizards, and file upload with progress

I needed a refresher on the template v/s reactive forms and also wanted to learn advanced signal based forms. This course is an excellent choice for someone looking for both versions. Thanks Vasco for this course. It definitely helped me in understanding Angular forms with ease.

By Dominik Rebitzer on 10/24/2025

Nice course and most of it is still valid and useful. If you write Angular 20 in the title and I don't get presented a single Signal in the whole course and a lot of *ngIf's, something's off. Also, don't only talk about strongly typed forms but actually implement one. As for the rest, you get a very good understanding on Angular Forms in general even if it is not up2date information.

By Alisson Trindade Souza on 6/3/2025

Very good course! I was able to learn some bits of info about reactive forms I didn't know before, specially when it comes to using Angular Material components. I enjoyed the techniques to build the upload file form component too.

By Max Tsai on 12/2/2024

Loved every bit of this course - insightful, helpful, and most important of all, really in depth. I would gladly pay for a part 2 which covers things dynamic forms, or just more use cases on how to work with all the apis. Really grateful for this course, and cheers.

By Jesus Rodriguez Lara on 1/8/2024

The course has an easy and intuitive way to explain the 2 important topics, that are the template and reactive forms. Althought, it is well organized, because in some feature you decide or need review some specific topic of the content it will be easy find it again.

I had completed Reactive Angular Course (with RxJS) and Angular Core Deep Dive before taking this one. As expected, this has been a very nice class. I'm a C/C++ person, and I needed to pick up a frontend framework that's supported by our IT infrastructure so that my team can have an engineering data interfacing and reporting tool. Moving on to the NgRx now with Testing Angular Apps and Routing in the queue! Thank you, Vasco, for sharing your professional experience with us!

By saranyaGovindaraj on 7/30/2023

Excellent course.The instructor explained the concept very clearly with examples and implementation.I would recommend others to take up this course if they want to know more about custom form control and control value accessor(CVA).

By jireh padua on 6/8/2022

same as before, since I'm purchasing all his angular tutorial... the lack of power point and a more in depth explanation will somewhat throw you off and search in youtube for a better explanation. I did search on youtube the part of control value accessor because I couldn't grasp his explanation very well... in the era where understanding how the program works is needed since trouble shooting takes a long time if not known. by taking this course, you will be skipping reading a lot from documentation about angular forms and you will learn the efficiency of using it. I still highly suggest all his courses and better know how you should take it in order so you'll be able to follow what you might have missed or else you will be googling a lot about the topic Kudos to the instructor!

By John Murray on 12/19/2021

Well covered. It would probably be beneficial to have git branches for the beginning of each section as many other courses do. This would allow you to jump right in on a specific section you were looking for, rather than have to go step by step.

By Catalina Zecchin on 6/8/2021

I thought the course was great. However, I think it should be explicitly said in the description that the instructor is going to use angular material throughout the whole course. Angular material is great, but I was looking for a great forms course that I could apply without using angular material. I'm sure I'll find the way, but in this sense it wasn't a perfect match for me.

Because he has created project and loaded and not explaining
