Form Validationv1.0.0

An e-commerce platform uses form validation to validate shipping, payment, and review steps in a multi-step checkout. Each step validates on blur and final submission, with server-side error mapping for address verification and payment authorization.

An insurance company implements a long, multi-step application form with complex cross-field rules (e.g., coverage dates must be after birth date). Validation occurs per-step with accessibility features for screen reader users, and server errors are mapped back to fields.

A SaaS product uses async validation to check username availability in real-time, combined with synchronous checks for email format and password strength. Accessible error announcements ensure users with disabilities can correct errors easily.

A healthcare provider's patient intake form uses Zod schemas shared between client and server for consistency. Validation includes required fields, date range checks (e.g., appointment date in future), and accessibility via aria-describedby, with secure draft persistence.

Offer a cloud-based API that provides schema validation rules (e.g., email, date, custom business rules) that clients can integrate into their forms. Revenue comes from monthly subscription tiers based on API call volume.

Provide consulting services to design and implement custom form validation workflows for clients, including schema sharing, UX timing, accessibility, and server parity. Bill by project or hourly.

Develop a plugin for low-code platforms (e.g., Retool, Bubble) that simplifies adding complex validation logic, sync and async rules, and accessibility patterns. Sell via plugin marketplace with one-time purchase or subscription.
