Recommendations and usage patterns that help the performance of your web applications.

API pre-connect

API pre-connect is recommended for improved request timings. To enable it, place the preconnect directive as early as possible in your head tag:

<html>
<head>
  <link rel="preconnect" href="https://cdn.fpjs.io">
  <link rel="preconnect" href="https://api.fpjs.io">
  ... styles, js etc

Note that you need to pre-connect to both CDN and API. If you're using the EU API, use this pre-connect URL: https://eu.api.fpjs.io
