Ultra lightweight utility to create DOM nodes.
Tested with Chrome dev tools:
This aims to somehow reflect the lifetime of an application, create a view and update the whole view at least once. In the case of uldu there is no dom diffing, just replacing an outdated view.
import {
TEXT_NODE_NAME,
createDom,
render,
renderClean,
} from 'uldu';
A DOM node with some text:
render(['p', 'A paragraph'], document.body);
<body>
<p>A paragraph</p>
</body>
Optional attributes:
render(['p', {class: 'foo', id: 'bar'}, 'A paragraph'], document.body);
<body>
<p class="foo" id="bar">A paragraph</p>
</body>
Nested nodes:
render(['p', 'This is ', ['b', 'awesome']], document.body);
<body>
<p>This is <b>awesome</b></p>
</body>
Document fragments:
render([
['p', 'Paragraph 1'],
['p', 'Paragraph 2'],
], document.body);
<body>
<p>Paragraph 1</p>
<p>Paragraph 2</p>
</body>
Text nodes:
render([TEXT_NODE_NAME, 'This is really ', ['b', 'awesome']], document.body);
<body>This is really <b>awesome</b></body>
