It's .innerHTML = '' for the 21st century!
Yet another library to diff and patch an existing DOM tree by efficiently comparing it to a string. Why? This library is a little bit different than others. It makes use of an HTML 's unique ability to create an inert document fragment, featuring:
- A real DOM tree
- Multiple root nodes
- Will not trigger resource loading prematurely
- Will not apply embedded stylesheets prematurely
- Will not trigger custom element constructors or lifecycle events prematurely
The live DOM is then patched with the inert fragment using a hyper-fast diffing algorithm for real DOM nodes. This ensures that things only start happening if and when they're supposed to, organically.
Play with it on CodePen.

The
and raw functions never touch the DOM so they're completely safe to use server-side.`js
const http = require('http');
const { html } = require('apply-html');const content = html
How are you today?
;module.exports = http
.createServer((req, res) => res.end(content.toString()))
.listen(3000);
`API
$3
-
{Element} DOM element with children to be patched.
- string {String|SafeString} String or SafeString containing safe HTML to render.Updates the content of the given element, making the fewest possible changes required to match the given string of HTML. The string is converted into an HTML
and the resulting DOM trees are compared. Returns the updated element.$3
A template tag that creates a new SafeString containing a string of HTML. Interpolated values are serialized based on type:
-
Array - Items are serialized then joined with an empty string ('').
- Boolean|null|undefined - Converted to an empty string ('').
- Function - Throws a TypeError.
- Number - Inserted as-is.
- Object - Converted to an HTML-encoded JSON blob.
- SafeString - Inserted as-is.
- String - HTML-encoded to safeguard against XSS). To opt out of escaping, use raw().$3
-
string {String}` String of safe HTML.Wraps a string in a SafeString to indicate that it's safe to be inserted into the document. Only use on trusted strings to safeguard against XSS).
The wrapped string.
Length of the wrapped string. Read only.
Returns the raw string.
Returns the raw string.
