Angular 22: Use Signal Forms inside Reactive Forms

Start using Signal Forms in your existing Angular app, one component at a time! 🚀 Want to master Angular Signal Forms? I just released a full course where we build a real Signal Form step-by-step covering validation, async validation, dynamic fields, custom controls, and submission patterns. 👉 Enroll here: https://www.udemy.com/course/angular-signal-forms/?couponCode=021409EC66FC6440B867 In this tutorial, we refactor a custom quantity control component from the old ControlValueAccessor pattern to the new FormValueControl concept from Angular Signal Forms. The best part? The parent form is built with standard Reactive Forms, and we don't change a single line of it. Angular 22 now supports seamless interoperability between custom controls built with FormValueControl and existing Reactive Forms and Template-Driven Forms, letting you incrementally adopt Signal Forms without rewriting your entire application. If you've been hesitant to start using Signal Forms in a large, complex app, this video will show you exactly how to take that first step. ------------------------------------------------------------------------------ 🔔 Subscribe for more Angular tutorials & tips → [🔗 https://www.youtube.com/c/briantreese?sub_confirmation=1] 👍 Like this video if you found it helpful, it really helps support the channel! ------------------------------------------------------------------------------ 🔗 Demo Links: - https://github.com/brianmtreese/template-and-reactive-forms-form-value-control-support ------------------------------------------------------------------------------ 📚 Additional Resources: - The commit that makes this all possible: https://github.com/angular/angular/commit/c4ce3f345fdb14595f0991dff488c4043a0fc71c - Angular Signal Forms Custom Controls Documentation: https://angular.dev/guide/forms/signals/custom-controls - My course "Angular Signal Forms: Build Modern Forms with Signals": https://www.udemy.com/course/angular-signal-forms/?couponCode=021409EC66FC6440B867 - My course "Angular: Styling Applications": https://www.pluralsight.com/courses/angular-styling-applications - My course "Angular in Practice: Zoneless Change Detection": https://app.pluralsight.com/library/courses/angular-practice-zoneless-change-detection ------------------------------------------------------------------------------ 🎓 Angular Certification (New) If you’re looking to validate your Angular skills, there’s now an official certification built and reviewed by Google Developer Experts.

Instead of implementing four ControlValueAccessor methods and wiring up manual callbacks, you simply expose a model() signal. Angular 22 now adds full interoperability, meaning FormValueControl-based controls work seamlessly alongside classic Reactive Forms and Template-Driven Forms via the standard formControlName directive, no parent form changes required. ------------------------------------------------------------------------------ #angular #angularforms #signalforms #angular22 #controlvalueaccessor #formvaluecontrol #reactiveforms #webdevelopment #typescript #angulartutorial #frontenddevelopment #angulardeveloper
