LOL(😂) HTML for Deno
Low output latency streaming HTML parser/rewriter with CSS selector-based API.
Example
import { concat } from "https://deno.land/std@0.125.0/bytes/mod.ts";
import init, { HTMLRewriter } from "https://deno.land/x/lol_html/mod.js"";
import wasm from "https://deno.land/x/lol_html/wasm.js"";
await init(wasm());
const enc = new TextEncoder()
const dec = new TextDecoder()
const chunks = [];
const parts = [
"<div><a href=",
"http://example.com>",
"</a></div>",
]
const rewriter = new HTMLRewriter("utf8", (chunk) => {
chunks.push(chunk);
});
rewriter.on("a[href]", {
element(el) {
const href = el
.getAttribute("href")
.replace("http:", "https:");
el.setAttribute("href", href);
},
});
for (const part of parts) {
rewriter.write(enc.encode(part));
}
rewriter.end();
console.log(dec.decode(concat(...chunks)));
