The problem is the HUGE amount of API calls we need to use in order to show the preview.</p> <h4 id="summary-steps-reproduce">Steps to reproduce</h4> <p>Just Remove the cache in public::/iconify-icons, and try to add any content in an iconify field.</p> <h3 id="summary-proposed-resolution">Proposed resolution</h3> <p>Use async capabilities of PHP (read this <a href="https://gorannikolovski.com/blog/asynchronous-and-concurrent-http-requests-in-php">https://gorannikolovski.com/blog/asynchronous-and-concurrent-http-requests-in-php</a>)</p> <p>In the generateSvg we should pass an array of icon names, so:<br> <code>&nbsp; public function generateSvg(string $collection, string $icon_name, array $parameters = []): string {</code><br> should be moved to<br> <code>&nbsp; public function generateSvg(string $collection, array $icons, array $parameters = []): string {</code></p> <p>So we should pass into the $icons paramater all the icons that belongs to the same collection.</p> <p>Inside the method:</p> <p>We should do all the API requests asynchronously (using a loop), and wait for all the promises.</p>
