ngx-form-stepper

ngx-form-stepper is an Angular library designed to create multi-step forms with field-level validation that is extremely strongly typed. It prevents invalid states at development time rather than runtime, ensuring robust, typed, and maintainable forms without complex configuration.

Key Features

• Strong Typing — Input types, default values, and validators are strictly typed, preventing mismatches during development.
• Compile-Time Validation — Common errors like duplicate return keys or invalid validator assignments are caught by the TypeScript compiler.
• Multi-Step Forms — Simple declaration of multi-step forms with per-step configuration and navigation.
• Field-Level Validation — Quick setup of per-field validators with type-safe compatibility checks.
• Custom Styling — Supports custom CSS class names for full styling control over form components.
• Consistent Values — Form values are always consistent with their defined types, ensuring data integrity.

Philosophy

ngx-form-stepper leverages TypeScript's type system to make the compiler an ally, guiding implementation and eliminating common form-building errors before runtime.
