Tiny utility (295B) to create DOM elements with manner.

Manually creating DOM nested elements can be very troublesome and verbose. Facon is a tiny utility that makes it easy to create nested DOM elements using template literals and extract references.

There's no magic nor restrictive template logic. All you get are dom references so that you can do whatever you like and take full advantage of the powerful native DOM API.

TLDR: Facon fix the tiring process of creating and assembling nested DOM elements or .innerHTML where you later have to query for references manually.

lack of Features

• Tiny (295B)
• Vanilla JS
• Zero Dependencies
• Fast

Install

$ npm install facon

This module exposes three module definitions:

• ES Module: dist/facon.mjs
• CommonJS: dist/facon.js
• UMD: dist/facon.min.js

Include facon:

// ES6
import f from 'facon'

// CJS
const f = require('facon');

The script can also be directly included from unpkg.com:

<script src="https://unpkg.com/facon"></script>

Usage

import f from 'facon';

// Create a <b> DOM element
let node = f`<b>Hello World</b>`;
document.body.appendChild(node);

// Create nested elements, and extract references
let node = f`
<div>
  <h1 ref="title">Façon</h1>
  <p ref="body">Create nested DOM elements with manner<p>
</div>
`;
document.body.appendChild(node);

let {title, body} = node.collect();
title.textContent = 'Hello World';

// DOM node appends
let child = f`<b>Hello World</b>;
let parent = f`<div>${child}</div>;

API

facon(string)

Returns: Element

Construct and returns a DOM element.

The returned element has a special collect method that is used to collect references to all elements with a ref attribute. Multiple elements containing identical ref attribute values result in an array of DOM references.

DOM Elements can be composed together/appended like this:

let myNode = document.createElement('div');
let node = f`<div>${myNode}</div>`;

// or this way
let myNode = document.createElement('div');
let node = f`<div>${myNode}</div>;

node.collect(options)

Returns: Object

Method for extracting DOM references. E.g:

const node = f`
  <div>
    <h1 ref="title">Hello world!</h1>
    <ul ref="list">
      <li ref="items">One</li>
      <li ref="items">Two</li>
      <li ref="items">Three</li>
    </ul>
  <div>
`;
let {title, list, items} = node.collect();
// ~> title is a dom reference to the inner h1 element.
// ~> list is a dom reference to the inner ul element.
// ~> items is an array of dom references to each li element.
// ~> node is by default the outer most element.

options.ref

Type: String
Default: ref

Attribute name used for collecting references.

options.keepAttribute

Type: Boolean
Default: false

Keep ref attributes on elements after collecting the references. Defaults to false.

options.to

Type: Object
Default: {}

Optional object reference to assign to.

This can be handy if you have a component and want to be able to access references trough this. E.g:

class MyElement extends Component {

    view() {
      const view = f`
        <div>
          <h1 ref="title">Façon</h1>
          <p ref="body>Create nested DOM elements with manner<p>
        </div>
      `;
      view.collect({to:this});
    }

    // later ...

    update() {
      this.title = 'Hello World';
      this.body = 'test';
    }
}
