Form Validation Done Right
summary
Asserts that validation belongs on the domain model not the UI and demonstrates a model-driven validation approach that runs on client and server, reuses rules across Reactive and Template Driven forms, and replaces hundreds of per-field directives (he cites ~100 custom validations) with a suite-based engine. Shows using the open-source Vest library, a validator directive + async validator pair, a set of input widgets, and claims two validators only for full integration — used in production for three years and working.
