<h4>External Services</h4>
When an API key is configured, this plugin connects to the BlockVault cloud API (operated by PerAstra) to sync your block library across sites. The following data is transmitted:
<ul>
<li>Your API key (for authentication)</li>
<li>Your site URL (for per-site tracking)</li>
<li>Block names, categories, and markup content (when saving or retrieving blocks)</li>
</ul>
No data is sent when using local mode (no API key configured).

<li>BlockVault cloud API endpoint: <a href="https://api.block-vault.com" rel="nofollow ugc">https://api.block-vault.com</a></li>
<li>Privacy Policy: <a href="https://block-vault.com/privacy" rel="nofollow ugc">https://block-vault.com/privacy</a></li>
<li>Terms of Service: <a href="https://block-vault.com/terms" rel="nofollow ugc">https://block-vault.com/terms</a></li>
</ul>
<h4>Source Code & Development</h4>
The full unminified source and the build tooling required to regenerate the compiled files are both included inside the plugin zip AND hosted publicly on GitHub.

</ul>
<h4>Source vs compiled files</h4>
The plugin zip contains both the original source and the compiled output:
<ul>
<li><code>src/</code> — original unminified JavaScript (React / JSX) and SCSS source. Everything the UI does is here.
<ul>
<li><code>src/index.js</code> — editor plugin entry point (registers the sidebar and context-menu integration)</li>
<li><code>src/components/</code> — sidebar, block list, block item, save modal</li>
<li><code>src/store/</code> — <code>@wordpress/data</code> Redux store</li>
<li><code>src/api/</code> — cloud API client, localStorage fallback, and the router between them</li>
<li><code>src/hooks/</code>, <code>src/utils/</code> — helpers for selected-block access, color/CSS resolution</li>
<li><code>src/style.scss</code> — sidebar styles</li>
</ul>
</li>
<li><code>build/</code> — compiled output loaded by WordPress. Not edited by hand. Includes:
<ul>
<li><code>build/index.js</code> (minified bundle of everything under <code>src/</code>)</li>
<li><code>build/style-index.css</code> and <code>build/style-index-rtl.css</code> (compiled from <code>src/style.scss</code>)</li>
<li><code>build/index.asset.php</code> (auto-generated dependency manifest)</li>
</ul>
</li>
</ul>
<h4>Build requirements</h4>
<ul>
<li>Node.js 18 or later</li>
<li>npm (comes with Node)</li>
</ul>
The only build tool is <a href="https://developer.wordpress.org/block-editor/reference-guides/packages/packages-scripts/" rel="nofollow ugc">@wordpress/scripts</a>, the official WordPress build wrapper around webpack + Babel. No custom webpack or Babel config is used — the defaults from <code>@wordpress/scripts</code> are used verbatim.
<h4>Rebuilding the compiled files</h4>
From the plugin directory, run:
<pre><code>npm install
npm run build
</code></pre>
That produces the contents of <code>build/</code> from <code>src/</code>. Other available commands (defined in <code>package.json</code>):
<ul>
<li><code>npm run start</code> — watch mode during development</li>
<li><code>npm run lint:js</code> — lint JavaScript</li>
<li><code>npm run lint:css</code> — lint SCSS</li>
</ul>
No PHP compilation is required — all PHP files (<code>perastra-blockvault.php</code>, <code>uninstall.php</code>, <code>includes/*.php</code>) are the original human-readable source.
