Install

The package is available to download through npm:

npm install z-textarea --save

Import as HTML/CSS component

The simple case

The package will be located inside the node_modules folder, you can import it into the HTML document as follows:

<link rel="stylesheet" href="node_modules/z-textarea/dist/style.css">

When bundling an web app

For bundlers that support CSS, like Webpack, you can use it like this:

require('z-textarea/dist/style.css');

Import as a Stateless Functional Component (SFC)

The package does not include the renderer, you can use any renderer that supports SFCs. You could use React, Preact, Inferno, etc.

Notice: This package contains CSS styling, you may need a bundler that's capable of requiring CSS files like Webpack with css-loader.

Once you have chosen the renderer you can include the package in your project as follows:

// Assuming the React renderer is being used
const React = require('react');
const render = require('react-dom').render;

// Passing the render function when importing
const ZTextarea = require('z-textarea')(React.createElement);

// Render it on page, using JSX here :)
render(<ZTextarea />, document.body);
