Video guide. https://www.youtube.com/watch?v=CcPajbjT6Zw&feature=youtu.be Did it one quick take. Good Enough start.

Best react form library of 2020. V 1.0

How I believe forms should work AS A UX perspective.

Premise 1. Make the user feel at ease.

Please Don't Interrupt the user with show error to the user until he completed his entry. It Slows down the user and might make them feel attacked.

The form field Error message should be displayed after clicks out of the input (on blur). Another annoyance is that with this user might think everything is right but when he clicks out then he sees error. This slow feedback might upset the user. To get arount this so we have to add one more thing called debounce. When the user stops typing for 3 seconds (debounce), then we can show the error messages.

Also, Technically we have keep in mind that.
A form can be invalid and not show errors. For example, the initial start position doesn't have anything filled out. It's not valid, but we don't want to show the mistakes on the default state. Form field validity should be tested on every change and blur.

Premise 2. Make it impossible to get wrong. Disable Form until the form Feilds are valid, making it clear that there a mistake in the Form.

How I believe forms should work from a developer perspective.

The code is super lightweight.

• .4kB MINIFIED
• 708B MINIFIED + GZIPPED

The validations are easy just one line a regex pattern (add pattern attribute to input)

<input
	name="email"
	onBlur={handleInputChange}
	onChange={handleInputChange}
	pattern="\S+@\S+\.\S+"
	value={values.email}
	/>

Prevent users from entering certain characters with just one line regex pattern. (add data-dontallow attribute to input)

<input
data-dontallow="[0-9]"
name="numbersOnly"
onBlur={handleInputChange}
onChange={handleInputChange}
value={values.numbersOnly}
/>

Easy to read. Lighting bug-free development Validate forms with one line regex pattern vs. 100 lines of code.

Form Valuations and key prevention is less than one l line per input.

Quick guide.

Install the package.

npm i -s react-useformhook-pro 

call in hook in the component

import useForm from 'react-useformhook-pro';

const { errors,
setErrors,
formSubmit,
handleInputChange,
isFormValid,
isValid,
setFieldValid,
setValues,
values} = useForm()

Optional: set initial values and valid states.

useForm = (
initialValues = {email:"test@gmail.com", name:"test"},
initialValidty = {email:true,name:false}
)

attach the handle handleInputChange,values,name and regex pattern to your component

Display errors.

<p> {errors.email&& "please enter a valid email" } </p>

Optional, don't allow specific values with regex patterns.

<input
name="email"
onChange={handleInputChange}
pattern="\S+@\S+\.\S+"
value={values.email}
data-dontallow="[0-9]"
/>

Lastly, only enable the Form when it's valid.

<button disabled={!isFormValid}> Submit Form </button>
