Wow Chat for Woo adds shopper-friendly product discovery to a WooCommerce store. Everything runs locally on your site — no account, no API key, and no external service.
<ul>
<li>Typo-tolerant catalog search backed by MySQL FULLTEXT and a custom ranker.</li>
<li>“Recently viewed”, “Related products”, and “Frequently bought together” recommendation widgets.</li>
<li>A FAQ chat bubble that doubles as an on-store product finder.</li>
<li>Gutenberg blocks for the search bar, recommendation grids, and chat widget.</li>
</ul>
<h3>Development</h3>
This plugin ships both the compiled assets (in <code>build/</code>) and their full, human-readable source so the build is reproducible.
<ul>
<li>JavaScript/TypeScript/SCSS source: <code>src/</code> — every bundle under <code>build/</code> is compiled from a matching entry point in <code>src/</code> (e.g. <code>build/admin/index.js</code> ← <code>src/admin/index.tsx</code>, <code>build/blocks/<name>/index.js</code> ← <code>src/blocks/<name>/index.js</code>).</li>
<li>Build tooling: <a href="https://www.npmjs.com/package/@wordpress/scripts" rel="nofollow ugc"><code>@wordpress/scripts</code></a> (webpack), configured in <code>webpack.config.js</code> and <code>tsconfig.json</code>. Dependencies and the build script are declared in <code>package.json</code> / <code>package-lock.json</code>.</li>
<li>Build the assets:
<ol>
<li><code>npm install</code></li>
<li><code>npm run build</code> — regenerates everything in <code>build/</code>.</li>
</ol>
</li>
<li>PHP dependencies: <code>composer.json</code> declares dev-only tooling (PHPUnit, WP Coding Standards). No runtime Composer dependencies. Run <code>composer install</code> then <code>vendor/bin/phpunit</code> for the PHP test suite.</li>
</ul>
No third-party JavaScript libraries are bundled into the compiled assets. The only external packages used (<code>@wordpress/*</code> and <code>react</code>) are not bundled — they load from the WordPress-provided script globals at runtime.

Add Google style instant search and search suggest to your WordPress powered site. This plugin will begin displaying search results as soon as your site visitor starts typing into the search box.
The plugin requires very little configuration and should work out of the box with most themes. The plugin has its own options page to configure the plugin to work with your theme if you require it.
