Angular 21 Signal Forms - complete guide. Typing, validation, custom controls, migration, gotchas. 👉

Signal Forms: reset() doesn't reset your value. It only clears touched/dirty state. Want value reset? Pass it: myForm().reset(initialValue) "Form doesn't own your data" - literally.

Custom controls in Angular: then vs now. ~15 lines of boilerplate → 1 line of intent. This is what framework evolution looks like.

Reactive Forms: 4 directives, zero type checking in templates Signal Forms: 1 directive, full type safety FieldTree<number> ≠ FieldTree<string> - caught at compile time, not in production 👇

Signal Forms: Why valueOf() instead of direct field access? In applyEach, paths are templates - not fields. valueOf() resolves the value relative to the item being validated. Critical for arrays. Good habit everywhere.

Signal Forms and undefined don't mix. - Optional fields in your form model? Expect TypeScript errors. Just use empty strings instead. #angular #signalforms

Signal Forms now has built-in debounce. This was a major concern - migrating from RxJS debounceTime felt risky. Now validators and async logic only trigger after the user stops typing. Migration to signals actually looks viable now 🚀 https://t.co/UQKovUOrd6
