beerio

Blazingly faster alternative to cheerio.

Supported only on Bun runtime and cloudflare.

For a simple benchmark, beerio performs 2.6x faster than cheerio.

const $ = beerio.load(`<h2 class="title">Hello world</h2>`);
$("h2.title").text("hello");
$.html();

The above code was benchmarked in mitata for both the libraries.

cpu: 12th Gen Intel(R) Core(TM) i7-12700H
runtime: bun 1.0.26 (x64-linux)

benchmark      time (avg)             (min … max)
-------------------------------------------------
beerio      4,090 ns/iter   (3,653 ns … 6,347 ns)
cheerio     10.69 µs/iter   (7,683 ns … 1,866 µs)

• How is beerio so fast?

  Beerio is a custom implementation of cheerio APIs by using underlying native HTMLRewriter to directly parse and manipulate the document quickly skipping both DOM parsing and rendering them back to HTML.

• Is beerio a drop-in replacement for cheerio?

  Yes, but partially. Beerio is an alternative and does not strive to be a full drop-in replacement. Although Beerio APIs are kept consistent and similar to cheerio's but as there is no full DOM parsing, beerio is able to implement only a small portion of cheerio APIs.
