@swimlane/dom-diff
This library acts as a base project for diffing chunks of dom or HTML for semantic equality.
Used in:
API
getDiffableHTML
Takes a snippet of HTML and returns a semantically similar diffable HTML snippet.
import { getDiffableHTML } from '@swimlane/dom-diff';
const h = `
<head></head>
<div z="1" a="2" x>
<h1 z="3">Hello</h1>
<h2>World</h2>
<svg>SVG ignored</svg>
<script>scripts also ignored</script>
<style>styles also ignored</style>
<!-- comments ignored too -->
</div>`;
getDiffableHTML(h, {
ignoreAttributes: [{ tags: ['h1'], attributes: ['z'] }]
});
// <div
// a="2"
// x
// z="1"
// >
// <h1>
// Hello
// </h1>
// <h2>
// World
// </h2>
// </div>dom
Template tag that takes a snippet of HTML and returns a regular expression.
Follows rules defined in https://github.com/Hypercubed/lit-regex
import { dom } from '@swimlane/dom-diff';
dom`<h1>Hello ${/[\w-]+/}</h1>`;
// /^<h1>\n Hello [\w-]+\n<\/h1>$/diff
Takes a regular expression generated by dom and a string generated from getDiffableHTML returning a representation of the difference.
import { diff, dom, getDiffableHTML } from '@swimlane/dom-diff';
const h = getDiffableHTML('<div>Hello 123</div>');
const r = dom`<div>Hello ${/[a-zA-Z]+/}</div>`;
diff(r, h);
// <div>
// - Hello \${/[a-zA-Z]+/}
// + Hello 123
// </div>Release
