webidx is a client-side search engine for static websites.

It works by using a simple Perl script (webidx.pl) to generate an SQLite database containing an index of static HTML files. The SQLite database is then published alongside the static content.

The search functionality is implemented in webidx.js which uses sql.js to provide an interface to the SQLite file.

You can see a live demo of it here.

1. use webidx.pl to generate the index:

$ /path/to/webidx.pl -x index.html -x archives.html --xP secret_files -o https://example.com -z . ./index.db

You can run webidx.pl --help to see all the available command-line options.

2. Include sql.js, pako and webidx.js in your web page:

<script src="https://cdnjs.cloudflare.com/ajax/libs/sql.js/1.10.1/sql-wasm.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/pako/2.1.0/pako.min.js"></script>
<script src="/path/to/webidx.js"></script>

3. Create a search form:

<form onsubmit="window.webidx.search({dbfile:'/webidx.db.gz',query:document.getElementById('q').value});return false;">
  <input id="q" type="search">
</form>

When the user hits the return key in the search box, a modal dialog will pop up containing search results!

The object that's passed to window.webidx.search() can have the following properties:

• dbfile: URL of the SQLite database file
• query: search query
• resultCallback: a callback which is passed an array of search results. Each result is an object with the title and url properties. If not defined, a modal dialog will be displayed.
• errorCallback: a callback which is passed any error string as an argument.
• titleSuffix: a string to be removed from the end of page titles.
• titlePrefix: a string to be removed from the beginning of page titles.
