PageFlash is a powerful WordPress plugin that preloads pages intelligently to boost site speed and enhance user experience. By loading pages before users click, PageFlash ensures instant page transitions, creating a seamless and lightning-fast browsing experience for your visitors.

Key Features:

Preloading:

  • Quicklink: Experience a 50% increase in conversions and enjoy 4x faster page loading. Boost your website speed and increase user engagement.
  • InstantPage: Uses just-in-time preloading — preloads a page right before a user clicks on it.

Performance Optimization:

  • Disable Dashicons: Remove Dashicons on the frontend for non-logged-in users to improve performance.
  • Disable Embeds: Disable the WordPress oEmbed feature to reduce unnecessary HTTP requests and improve page load times.
  • Disable Emojis: Remove built-in WordPress emoji scripts and styles to reduce page size and improve load times.
  • Disable Heartbeat: Control WordPress Heartbeat API everywhere or in certain areas (used for auto-saving and revision tracking) with customizable behavior and frequency settings.
  • Remove jQuery Migrate: Remove jQuery Migrate script to improve performance on the frontend.

Security Enhancements:

  • Disable REST API: Disable the WordPress REST API for non-authenticated users to enhance security and reduce unnecessary requests.
  • Remove REST API Link: Remove REST API link tag from the front end and the REST API header link from page requests.
  • Hide WordPress Version: Hide the WordPress version number from the site header, meta tags, and RSS feeds to improve security.
  • Disable XML-RPC: Disable the XML-RPC feature to enhance security and reduce unnecessary requests.

How it works:

  • Detects links within the viewport (using Intersection Observer)
  • Waits until the browser is idle (using requestIdleCallback)
  • Checks if the user isn’t on a slow connection (using navigator.connection.effectiveType) or has data-saver enabled (using navigator.connection.saveData)
  • Prefetches URLs to the links (using <link rel=prefetch> or XHR). Provides some control over the request priority (can switch to fetch() if supported).
