🎛️ Regulatio

High performance regulated inputs with custom validation.

Why?

I like the React controllable inputs experience but I never knew how to ensure similar performance without React. I did my research and finally realized the solution.

You're looking at it right now.

What it does?

It regulates <input> fields, allowing your users to enter only the values that are approved by your validation function. Validation function can be arbitrary and it is not limited to just regex.

Usage

npm install mvoloskov/regulatio

or

<script src="https://cdn.jsdelivr.net/gh/mvoloskov/regulatio/dist/regulatio.min.js"></script>

const input = document.getElementById('your-input')
const allowOnlyIntegersGreaterThanZero = value => /\d*/g.test(value) && parseInt(value, 10) > 0

const destroy = regulatio(input, allowOnlyIntegersGreaterThanZero)

// remove all event listeners when we don't need them anymore
destroy()

Enjoy!
