Felte: A form library for Svelte

Felte is a simple to use form library for Svelte. It is based on Svelte stores and Svelte actions for its functionality. No Field or Form components, just plain stores and actions to build your form however you like. You can see it in action in this CodeSandbox demo!

Features

• Single action to make your form reactive.
• Use HTML5 native elements to create your form. (Only the name attribute is necessary).

• No assumptions on your validation strategy. Use any validation library you want or write your own strategy.
• Handles addition and removal of form controls during runtime.
• Official solutions for error reporting using reporter packages.
• Well tested. Currently at 99% code coverage and constantly working on improving test quality.
• Supports validation with yup, zod and superstruct.
• Easily extend its functionality.
