HTSX

Build UIs with native HTML in JS.

• The whole package is just 838 bytes! minified, gzipped and has 0 dependencies
• Rendering 1000 test elements takes about 25ms which is ~21x faster than JSX (540ms) 🚀
• It's not wrapping or parsing anything, it's native HTML in your JavaScript.
• Full Typescript support

Install

npm install htsx

or with Yarn:

yarn install htsx

Usage

You can use HTSX everywhere you want.

• In node or browser: import htsx from 'htsx';
• In modern browser (without any build tool): import htsx from './htsx.min.js';
• Or via script tag: <script src="htsx.min.js"></script>

And start creating your UI with htsx template literal.

Example

Live demo: Codepen.io demo

const info = 'This is awesome!';
const handler = () => {};

const Component = htsx`
  <section>
    <h1>HTS</h1>
    <span>Next level UI builder</span>
    ${info}
    <button class="btn" onclick=${handler}>Download (1.5kb)</button>
  </section>
`;

document.body.appendChild(Component);

API

Elements

htsx is not like HTML, it is HTML. You can use any tag you want with all html attributes.

const Component = htsx`
    <h1>Hello!</h1>
    <div class="box">I'm a box</div>
`;

document.body.appendChild(Component);

Properties

You can simply render your properties just like this

const name = 'Mike';

const Component = htsx`
    <span>${name}</span>
`;

document.body.appendChild(Component);

Or pass props down:

const Component = (props) => htsx`
    <span>${props.name}</span>
`;

document.body.appendChild(Component({ name: 'Mike' }));

Events

You can attach events to elements in the simplest way.

const handler = (event) => {

};

const Button = htsx`
    <button onclick=${handler}>Click me!</button>
`;

or with your parameters

const handler = (param, event) => {

};

const Button = htsx`
    <button onclick=${handler.bind(this, 'foo')}>Click me!</button>
`;

All native event types are supported: onclick, onchange, onkeyup, onkeypress.

Nested elements

With htsx you can simply compose your elements:

const HelloElement = htsx`
    <span>Hey!</span>
`;

const Container = htsx`
    Hello!
    ${HelloElement}
`
