.htaccess Punk

.htaccess Punk checks the redirect targets defined in .htaccess files. It follows redirect chains to verify where they ultimately resolve and what HTTP status they return, thus helping to fight redirect rot.

Usage

CLI Use

npx htaccess-punk [options] [directory]

directory defaults to the current working directory. .htaccess Punk scans it recursively.

Option	Short	Description
--errors	-e	Show only error results (HTTP 4xx+ and connection failures); summary still reflects all checked URLs
--help	-h	Show usage information

Programmatic Use

import { check } from 'htaccess-punk';

const { files, urls, urlToFiles, results } = await check('/path/to/dir');

urlToFiles is a Map<string, string[]> of each target URL to the .htaccess files that reference it. results is an array of objects:

{
  url,      // original target URL
  status,   // final HTTP status code
  finalUrl, // final URL after following redirects (null if no redirects)
  chain,    // array of `{ url, status }` for each hop
  error,    // error message if the request failed (`status` and `finalUrl` absent)
}

check() also accepts an options object:

await check(dir, {
  concurrency: 5,               // parallel requests (default: 5)
  onReady({ files, urls }) {},  // called after files are found and targets extracted
  onResult(result) {},          // called for each result as it comes in
});

How It Works

.htaccess Punk:

• finds all .htaccess files in the given directory, recursively (skipping node_modules and .git)
• parses Redirect, RedirectPermanent, RedirectTemp, RedirectMatch, and RewriteRule directives to extract absolute target URLs
• skips targets that contain regex backreferences ($1, %1, etc.)—these depend on the matched request path and can’t be checked without it
• deduplicates targets across all files
• checks each unique URL with a HEAD request (falling back to GET if the server returns 403 or 405), following redirect chains up to 10 hops, and reports the final HTTP status

The check() function returns raw result data. The CLI (bin/htaccess-punk.js) collects those results and prints them grouped by .htaccess file, with the final status color-coded: green for 2xx, yellow for 3xx (further redirect from the final hop, e.g. a loop or exceeded redirect limit), red for 4xx/5xx. When a target redirected before settling, the final URL is shown below it.
