Examples

These examples show Fynix at the point where validation becomes useful in an application: a request arrives, rules are defined, an object is validated, and the returned result is mapped into a form or API response.

Every example includes:

• the DTO or value being validated
• the rule definition
• representative invalid input
• the exact result shape
• the API choice that fits the workflow

Example	What it demonstrates
Registration workflow	Nested DTOs, conditional requiredness, and API errors.
Nested order validation	Arrays of objects and dot-notated error paths.
Field and API errors	Standalone values, validate(), and validateAll().
Interactive playground	Edit sample values in the browser and inspect a representative returned result.

The registration guide provides the longer tutorial version of the first example. These pages focus on copyable patterns and their output.
