If you're using Signal Forms with async validation, you've probably run into a frustrating issue. You either debounce every validator with the debounce() function, or you end up hitting your API on every keystroke. Neither is great, but Angular 22 fixes this in a really clean way. This post walks through how the new built-in debounce works and why it makes Signal Forms even better.
What if you could start using Signal Forms today without touching your existing Reactive or Template-driven forms at all? In Angular 22, you'll be able to build Signal-based custom form controls that drop right into your existing forms with no massive rewrites required. This post walks through how to migrate a custom control from ControlValueAccessor to FormValueControl while keeping the parent form completely intact.
Every Angular developer has faced it, an input that spams the backend with every single keystroke. The classic solution involves pulling in RxJS and using debounceTime, but it requires converting signals to observables and thinking in streams. As of Angular v22, there’s a new, cleaner way. The new experimental debounced() signal primitive lets you solve this problem in a more declarative, signal-native way. This post walks through the old way and then refactors it to the new, showing you exactly how to simplify your async data-fetching logic.
