Questions
- Does it work with both reactive and template-driven forms?
- Yes. Every validator ships as a ValidatorFn for reactive forms and as a standalone directive for template-driven forms — import them one by one or all at once via NGV_DIRECTIVES.
- Which Angular versions does it support?
- Angular 17 through 22 — the widest range in the catalogue, so it works in apps that have not yet left 17.
- What is free and what needs a licence?
- Number, string, date, UUID, JSON and IP validators plus normalising transforms are free. A licence adds the scored password engine, credit card and IBAN checks, age rules, cross-field validation and metadata-accurate international phone validation.
- What happens if a licence key is invalid or expired?
- The library falls back to the free tier without breaking the form. Verification is offline; keys can be restricted by hostname and expiry, and local development hosts always work without one.
- Does it add much to the bundle?
- The package is tree-shakeable: each validator is a separate export, so the bundle carries only the validators you actually import.
