Tired of looping through errors just to check one specific validation rule? 🚀 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 video, you’ll learn how to get specific validation errors in Angular Signal Forms using a real-world password checklist example. We explore why relying on the errors() array and indexes can lead to unstable and buggy behavior, and how using errors().find() becomes repetitive and inefficient. Then we introduce the new getError() API in Angular 22, which provides a cleaner, more reliable way to check targeted validation rules. If you’re working with Angular forms, validation logic, or migrating from reactive forms to Signal Forms, this pattern will simplify your templates and improve maintainability. ------------------------------------------------------------------------------ 🔔 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/Getting-Specific-Validation-Errors-with-Signal-Forms ------------------------------------------------------------------------------ 📚 Additional Resources: - The commit that makes this all possible: https://github.com/angular/angular/commit/709f5a390ca0de04f8066012a5cb36999f2fd4a6 - 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 ------------------------------------------------------------------------------ 📖 Chapters: 0:00 – Introduction 0:29 – A Password Checklist with Angular Signal Forms 1:11 – Reviewing the Starting Signal Forms Setup 3:14 – Why Error Indexes Break in Angular Signal Forms 4:55 – Using errors().find() to Check Validation Rules 5:48 – Angular 22: Using getError() for Clean Validation Checks 7:50 – Why getError() Makes Signal Forms Easier to Use ------------------------------------------------------------------------------ 🧰 About the Tools Used This video covers Angular Signal Forms, a modern forms API built on Angular Signals, and introduces the new getError() method in Angular 22. You’ll see how built-in validators and custom validation rules work together, and how FieldState enables reactive validation handling. The tutorial also compares patterns from reactive forms like hasError() to newer signal-based approaches. ------------------------------------------------------------------------------ 🎓 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. It covers modern Angular concepts and is one of the first structured ways to demonstrate real-world Angular knowledge. 👉 https://certificates.dev/angular?friend=TREESE (They’re currently offering up to 50% off) ------------------------------------------------------------------------------ #angular #angular22 #signalforms #angularforms #webdevelopment #frontenddevelopment #javascript #typescript #angularsignals #formvalidation
