Domose

Old Fashioned DOM Sugar

Domose is one of those old fashioned sugary micro libraries that aims to give you delicious DOM functionality in every browser.

npm install domose --save

Some of this stuff should be native, and I hope one day it is. Other stuff here is native, so only use it when you still need to support IE9 or Edge and can’t justify the polyfill. Everything here is modular, so you can just use the parts you need. Everything is also super tiny, so even using the whole thing costs less than 1 kilobyte.

Speculative DOM Functionality

Here are some no-nonsense explanations about new functionality you’ll get.

The $assign Method

The $assign method assigns an element with attributes, events, and children. It returns the element.

import { $assign } from 'domose';

Create an Element when the first argument is a string:

$assign('div');

Append nodes with the second argument onward:

$assign(element, ...nodes);

Add event listeners with Function values in the second argument onward:

$assign(element, { click: (event) => { console.log(event) } });

Or set dashed attributes from Object values:

$assign(element, { aria: { label: 'This text is an aria label.' } });

Or set any other attribute:

$assign(element, { role: 'button' });

And work with namespaced elements:

$assign(
  document.createElementNS('http://www.w3.org/2000/svg', 'svg'),
  {
    viewBox: '0 0 32 32'
  }
);

I’ve proposed a native assign() method.

Cost: Up to 252 bytes to your gzipped script.

The $dispatchEvent Method

The $dispatchEvent method dispatches an event from an element.

Unlike the native dispatchEvent method, it accepts a name of a custom event as the first parameter, and an event

import { $dispatchEvent } from 'domose';
 
$dispatchEvent(element, new CustomEvent('my-event' { bubbles: true, detail: { foo: 'bar' } }));
 
// or
 
$dispatchEvent(element, 'my-event', { bubbles: true, detail: { foo: 'bar' } });

I’ve proposed this functionality for the native dispatchEvent() method.

Cost: Up to 190 bytes to your gzipped script.

The $replaceAll Method

The $replaceAll method removes all children from an element, optionally appending new children.

import { $replaceAll } from 'domose';
 
$replaceAll(element);

I’ve proposed a native replaceAll() method.

Cost: Up to 189 bytes to your gzipped script.

The $wrapWith Method

The $wrapWith method wraps an element within another element. It returns the element.

import { $wrapWith } from 'domose';
 
$wrapWith(element, wrapperElement);

I’ve proposed a native wrapWith() method.

Cost: Up to 85 bytes to your gzipped script.

Emerging DOM Functionality

Use these methods when your supported browsers can’t do them on their own, and when you’re not in a position to add a polyfill.

The $after Method

The $after method inserts content after an element. It returns the element. If possible, use the native after method, which works in a similar way.

import { $after } from 'domose';
 
$after(element, sibling1, sibling2, 'a new text node');

Cost: Up to 98 bytes to your gzipped script.

The $append Method

The $append method appends children to an element. It returns the element. If possible, use the native append method, which works in a similar way.

import { $append } from 'domose';
 
$append(element, child1, child2);
$append(element, child1, 'a new text node');

Cost: Up to 116 bytes to your gzipped script.

The $before Method

The $before method inserts content before an element. It returns the element. If possible, use the native before method, which works in a similar way.

import { $before } from 'domose';
 
$before(element, sibling1, sibling2, 'a new text node');

Cost: Up to 80 bytes to your gzipped script.

The $closest Method

The $closest method returns the closest ancestor element that matches a given selector. If possible, use the native closest method, which works in a similar way.

import { $closest } from 'domose';
 
$closest(element, '.some-class');

Cost: Up to 182 bytes to your gzipped script.

The $matches Methods

The $matches method returns whether or not a DOM element matches a given selector. If possible, use the native matches method, which works in a similar way.

import { $matches } from 'domose';
 
$matches(element, '.some-class');

Cost: Up to 128 bytes to your gzipped script.

The $prepend Method

The $prepend method prepends children to an element. It returns the element. If possible, use the native prepend method, which works in a similar way.

import { $prepend } from 'domose';
 
$prepend(element, child1, child2);
$prepend(element, child1, 'a new text node');

Cost: Up to 182 bytes to your gzipped script.

The $remove Method

The $remove method removes an element from its parent. It returns the element. If possible, use the native remove method, which works in a similar way.

import { $remove } from 'domose';
 
$remove(element);

Cost: Up to 69 bytes to your gzipped script.

The $replaceWith Method

The $replaceWith method replaces an element within another element. It returns the element. If possible, use the native replaceWith method, which works in a similar way.

import { $replaceWith } from 'domose';
 
$replaceWith(element, replacer);

Cost: Up to 63 bytes to your gzipped script.

Emerging Event Functionality

Use these methods when your supported browsers can’t do them on their own, and you’re not in a position to add a polyfill.

The $CustomEvent Method

The $CustomEvent creates a custom event. If possible, probably use the native new MouseEvent(), new CustomEvent(), etc. methods.

import { $CustomEvent } from 'domose';
 
element.dispatchEvent(new $CustomEvent('click', { bubbles: true }));
element.dispatchEvent(new $CustomEvent('foo', { detail: { bar: 'qux' } });

Cost: Up to 154 bytes to your gzipped script.

The $fetch Method

The $fetch method fetches response text from a URL and passes it to a callback. It returns the XHR request (which is how it works). If possible, please use the native fetch method, which is totally better than this.

import { $fetch } from 'domose';
 
$fetch('api?foo=bar', (responseText) => { /* do something */ });

Cost: Up to 159 bytes to your gzipped script.
