Getting started

Felte is a JavaScript library that tries to help you ease the management of forms, form validation and the reporting of validation errors. To use its basic functionalities you'll only need the base felte package from npm.

npm i -S felte

# Or if you use yarn

yarn add felte

Then, inside of the Svelte component where you have your form, import the createForm function and call it with a configuration object containing an onSubmit function. The createForm function returns an action that you can use in any form. This is all you need to make your form reactive.

  import { createForm } from 'felte';

  const { form } = createForm({
    onSubmit: (values) => {
      // ...

<form use:form>
  <input type="text" name="email">
  <input type="password" name="password">
  <input type="submit" value="Sign in">

Felte does not export any components like Form, Field or anything like that, but you do need to make felte aware of your inputs by assigning a name to them.

Felte also offers validation handling and error reporting but this is all you need for the most basic, validation-less form.
