Svelte Formula

Zero-Configuration Reactive forms for Svelte

Overview

The Svelte Formula is a library for creating reactive forms in Svelte applications. It enhances the ability to create rich, data-driven applications by providing Zero Configuration reactive form components. With Formula, all you need is a well-defined HTML5 form element and the library takes care of creating reactive stores for data and form states.

Features

  • Zero Configuration: Formula requires only a well-defined HTML5 form element to create fully reactive stores of data and form states.
  • Support for Various Input Types: Formula supports single and multi-value inputs for all widely supported HTML inputs. It also extends support to checkbox groups, radio groups, and composite fields of values like text or number.
  • Customizable Validation: Formula allows for form and field level validations, which integrate with the in-built browser validations. Custom validation messages can also be provided for localization.
  • Lifecycle Methods: Formula provides additional lifecycle methods for dynamically adding and removing customizations, and for resetting or destroying the form.
  • Accessibility: Formula attempts to apply ARIA attributes to improve accessibility.

Installation

To install the Svelte Formula library, run the following command:

npm i svelte-formula

Svelte

Svelte is a modern front-end framework that compiles your code at build time, resulting in smaller and faster applications. It uses a reactive approach to update the DOM, allowing for high performance and a smoother user experience.

eslint
Eslint

ESLint is a linter for JavaScript that analyzes code to detect and report on potential problems and errors, as well as enforce consistent code style and best practices, helping developers to write cleaner, more maintainable code.

typescript
Typescript

TypeScript is a superset of JavaScript, providing optional static typing, classes, interfaces, and other features that help developers write more maintainable and scalable code. TypeScript's static typing system can catch errors at compile-time, making it easier to build and maintain large applications.
