Bun provides a fast native implementation of the `HTMLRewriter` pattern developed by Cloudflare. It provides a convenient, `EventListener`-like API for traversing and transforming HTML documents.
|
|
|
|
```ts
|
|
const rewriter = new HTMLRewriter();
|
|
|
|
rewriter.on("*", {
|
|
element(el) {
|
|
console.log(el.tagName); // "body" | "div" | ...
|
|
},
|
|
});
|
|
```
|
|
|
|
To parse and/or transform the HTML:
|
|
|
|
```ts#rewriter.ts
|
|
rewriter.transform(
|
|
new Response(`
|
|
<!DOCTYPE html>
|
|
<html>
|
|
<!-- comment -->
|
|
<head>
|
|
<title>My First HTML Page</title>
|
|
</head>
|
|
<body>
|
|
<h1>My First Heading</h1>
|
|
<p>My first paragraph.</p>
|
|
</body>
|
|
`));
|
|
```
