Until Angular 14, Reactive Forms did not include type definitions in many of its classes, and TypeScript would not catch bugs like in the following example during compilation.

Angular 14, the next major upgrade to the popular Google-developed, TypeScript-based web framework, will feature strictly typed reactive forms and extended template diagnostics.

TanStack Form 1.0 is ready for use in production and can handle the React, Vue, Angular, Solid and Lit frameworks. The development team provides examples of the respective use.
