SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Building forms in client apps often leads to duplicated boilerplate, inconsistent validation, and wiring between form state and the rest of the app. This Skill provides reusable form patterns and integrated validation for Composable Svelte to streamline form creation and maintenance.

Core Features & Use Cases

  • Zod-based validation: Seamlessly validate form data with Zod schemas and provide field-level errors.
  • FormConfig + createFormReducer: Centralize form setup and manage form state via reducers for predictable behavior.
  • Reactive wrappers: Use lightweight reactive patterns to bind form state to parent components and share form logic.

Quick Start

Define a Zod schema, create a formConfig, and wire it into a Svelte component using a reactive wrapper pattern to connect the form state to the UI and handle submission.

FAQPage Schema
How do I validate forms in Svelte using Zod schemas?

You can validate Svelte forms using Zod schemas by defining a schema and wiring it into a FormConfig to provide reactive, field-level validation errors. This integrates schema validation directly into your form state management.

What is the best way to manage form state in Svelte?

The best way to manage Svelte form state is using a createFormReducer combined with a FormConfig to centralize setup. This approach ensures predictable behavior and allows reactive wrappers to bind state to parent components.

Can I perform async validation on Svelte form fields?

Yes, you can perform async validation on Svelte form fields. The Skill's FormConfig and Zod integration support asynchronous validation requirements, allowing you to handle complex server-side or remote checks seamlessly.

How do I share form logic across multiple Svelte components?

You share form logic across Svelte components by using lightweight reactive wrapper patterns. These wrappers bind the centralized form state and validation rules to parent components, eliminating duplicated boilerplate.

Does this approach work for form-heavy Svelte applications?

Yes, this approach is specifically designed for form-heavy Svelte applications requiring structured FormConfig and state management. It streamlines maintenance by providing reusable patterns and integrated validation across multiple components.

Why does my Svelte form validation produce inconsistent errors?

Inconsistent Svelte form validation errors often result from duplicated boilerplate and disconnected state management. Centralizing validation with Zod schemas and a createFormReducer provides predictable, field-level error handling.
