Meronex Form

Simple React forms with validation for React MUI.

Features

• ✅ Validate onBlur or onChange
• ✅ Same API for classes and functional components
• ✅ Easy to fork and modify to your needs

Usage

1. Install npm i @meronex/form

2. Import import Form from '@meronex/form';

3. Add the form <Form ref={validatedForm} onUpdate={(_formData) => { setFormData(_formData); }} blurDelay={500}> ... React MUI Fields Here </Form

   Notice that we've a ref attached which exposes a validatedForm.reset() method and we've an onUpdate method which is triggered every time there change to the form. The blurDelay default is zero, and it used to delay blur validation to allow time for animation etc.

4. Add the @material-ui fields with name (required), defaultValue (optional for edit forms) and validator (optional for validation) attributes.

   <TextField name={'name'} label="Name" defaultValue={'a'} validate={(v) => { if (!v || v === '') return 'Name is required..!!'; return true; }} />

   That's it! The onUpdate will be triggered with all the form data, you can then set it to the state object.

   note that the defaultValue and validator are optional. You only need the name attribute for the form to hook for the field. Also, this works with the TextField using select attribute.

Props & Functions

Prop	Description
name *	Required field to hook the form to the field
defaultValue	Optional default value
validator	Validator function to be triggered onBlur
blurDelay	Intenger to delay triggering the blur validation in ms
validateOnInit	Boolean value to validiate on form init

The Form also exposes the following ref functions:

Function	Description
reset()	Reset the form
validate()	Force validate the form

Why?

1. Dead-simple API
2. Minimal documentation/concepts
3. Easy to fork, copy and modify (it is only a single file with no build step)
4. Zero dependencies
5. Extremely tiny (1.2kb minified + gzipped)

How it works?

The Form component will bind methods/props to the child fields. The value, onBlur, onChange, error and helperText props are automatically handled, a form object is created to capture the state of the form and that object is passed to the onUpdate method with every change.
