<h4>Live Data Display is a powerful WordPress plugin that loads JSON feeds via HTTP and displays live-updating values on your site — with no page reload required.</h4>
Perfect for live tickers, stock prices, sports results, weather data, sensor readings, and any other real-time data source.
Key Features:
<ul>
<li>Multiple independent slots: Configure as many data slots as you need, each with its own API URL, refresh interval, and display target.</li>
<li>Shortcode and Gutenberg block: Place data anywhere with <code>[araa slot="slot_1"]</code> or the built-in block.</li>
<li>Auto-refresh: Each slot refreshes independently at a configurable interval (minimum 500 ms).</li>
<li>Server-side initial value: For slots with a refresh interval ≥ 10 s the initial value is pre-rendered server-side and cached, so visitors see data immediately — no flash of empty content.</li>
<li>Proxy for cross-origin APIs: Optional server-side proxy (admin-ajax or REST API) fetches external URLs from the server, bypassing browser CORS restrictions.</li>
<li>Customisable GET parameters: Use <code>#GET_key#</code> placeholders in the API URL to pass the current page’s GET parameters to the remote API.</li>
<li>Prefix / Suffix: Wrap every displayed value with configurable text (e.g. currency symbol, unit).</li>
<li>Error text: Show a custom fallback message when the API request fails or the JSON path is not found.</li>
<li>Page-visibility aware: Slots pause polling while the browser tab is hidden and resume immediately when it becomes visible again.</li>
<li>Active / Inactive toggle: Enable or disable individual slots without deleting their configuration.</li>
<li>Built-in demo APIs: The plugin ships with six ready-to-use REST API endpoints that can serve as live data sources straight away — no external service needed. Each endpoint must be individually enabled under Settings → Live Data Display → API:
<ul>
<li><code>/wp-json/araa/v1/api/time</code> — current server time, date, weekday, and timezone</li>
<li><code>/wp-json/araa/v1/api/countdown</code> — seconds/days until a target date (<code>?to=YYYY-MM-DD</code>; defaults to next New Year)</li>
<li><code>/wp-json/araa/v1/api/random</code> — random integer within a configurable range (<code>?min=1&max=100</code>)</li>
</ul>
</li>
<li>Clean uninstall: All plugin data is removed on deletion (optional: keep settings).</li>
</ul>
How It Works:
<ol>
<li>Add a slot: Go to Settings → Live Data Display and create a slot.</li>
<li>Enter the API URL: Paste the JSON feed URL. Use <code>#GET_key#</code> for dynamic GET parameters.</li>
<li>Set the JSON path: Enter the dot-separated path to the value you need (e.g. <code>items.0.score</code>).</li>
<li>Choose a proxy method (only needed for external/cross-origin URLs): admin-ajax or REST API proxy.</li>
<li>Set the refresh interval: How often (in milliseconds) should the value be updated?</li>
<li>Place the output: Use the shortcode <code>[araa slot="slot_1"]</code>, the Gutenberg block, or a custom CSS/jQuery selector.</li>
<li>Optional: Add prefix, suffix, placeholder, error text, and an initial-hide selector.</li>
<li>Optional — enable REST API: To expose slot values via the plugin’s own REST API endpoints, go to Settings → Live Data Display → API and activate the feature. The endpoints are disabled by default.</li>
</ol>
