Dependency-free DOM library for handling HTML and CSS files on server-side.
// const { document } = require("@litejs/dom");
import { document, CSSStyleSheet, DOMParser, XMLSerializer } from "@litejs/dom";
import { XMLHttpRequest } from "@litejs/dom/net.js";
// Build DOM manually
const el = document.createElement("h1");
el.id = 123;
el.className = "large";
const fragment = document.createDocumentFragment();
fragment.appendChild(document.createTextNode("hello"));
el.appendChild(fragment);
// Replace the DOM tree with HTML
el.innerHTML = "<b>hello world</b>";
console.log(el.toString());
// <h1 id="123" class="large"><b>hello world</b></h1>
// Minify HTML
console.log(el.toString(true));
// <h1 id=123 class=large><b>hello world</b></h1>
el.querySelectorAll("b");
// [ "<b>hello world</b>" ]
// Use XMLHttpRequest in server side
const xhr = new XMLHttpRequest();
xhr.open("GET", "https://litejs.com");
xhr.responseType = "document";
xhr.onload = function() {
const doc = xhr.responseXML;
// Work with DOM in familiar way
console.log(doc.querySelector("title").textContent);
}
xhr.send();
// Minify CSS
const sheet = new CSSStyleSheet({ min: { color: true } })
sheet.replaceSync(".a { color: hsl(0 0% 100%) }")
console.log(sheet.toString())
// .a{color:#fff}
