autoresize

Automatically resize the inputs.

Examples

You can try TextArea or Input examples in your browser. Note: Autoresize of the <input> element is not yet implemented.

Install

Node

npm i autoresize

Then in your project require it:

const autoresize = require('autoresize');

Or use ES import:

import autoresize from 'autoresize';

Browser

Note: You will have access to the global autoresize function, that will be added to the window object.

Usage

const element = document.querySelector('#textarea');
const options = { maximumRows: 5, assumeRendered: true };

// Enable autoresize by adding specific listeners
const disable = autoresize(element, options);

// Remove all listeners and disable autoresize
disable();

Paramenters

element

An HTML element of types: HTMLTextAreaElement or HTMLInputElement.

options

An options object, that is different for each element type.

TextArea

{
  minimumRows: 1,
  maximumRows: Infinity,
  rowHeight: null,
  assumeRendered: false
}

Passing the rowHeight value may be a bit more performant solution, but it will mean that the lineSize is guarantee to be unchanged in future with JS or CSS (including some @media queries). Otherwise, rowHeight will be calculated on the initial step and recalculated on window 'resize' event.

Passing the assumeRendered with true value will skip the check for the presence of the element in the DOM. Otherwise, the render() function will wait, until the element is rendered and then will apply the event listeners.

Input

{
  maxWidth: null,
  assumeRendered: false
}
