<p>Flying Pages preload pages before the user click on it, making them load instantly</p>
<h3>How it Works?</h3>
<p>Flying Pages injects a tiny JavaScript code (1KB gzipped), waits until the browser becomes idle. Then it detects pages in the viewport and on mouse hover and preloads them.</p>
<p>Flying Pages is intelligent to make sure preloading doesn’t crash your server or make it slow.</p>
<ul>
<li>
<p><strong>Preload pages in the viewport</strong> – Detect links within the viewport (current viewing area) using ‘Intersection Observer’ and tells the browser to preload them using ‘prefetch’, switch to xhr if not available (similar to <a href="https://github.com/GoogleChromeLabs/quicklink" rel="nofollow ugc">Quicklink</a>).</p>
</li>
<li>
<p><strong>Preload pages on mouse hover</strong> – On hovering links, if it’s not preloaded yet using above ‘viewport’, then Flying Pages will prefetch them instantly (similar to <a href="https://instant.page/" rel="nofollow ugc">Instant.page</a>).</p>
</li>
<li>
<p><strong>Limits the number of preloads per second</strong> – If your page has too many links, prefetching all at the same time will cause the server to crash or slow down the website to visitors. Flying Pages limits the number of preloads per second (3 req/sec by default) using an in-built queue. For example, if you’ve 10 links in the viewport, preloading all these are span into 4 seconds.</p>
</li>
<li>
<p><strong>Stops preloading if the server is busy</strong> – In case the server starts to respond slowly or return errors, preloading will be stopped to reduce the server load.</p>
</li>
<li>
<p><strong>Understands user’s connection and preferences</strong> – Checks if the user is on a slow connection like 2G or has enabled data-saver. Flying Pages won’t preload anything in this case.</p>

</ul>

<p>DNS resolution time can lead to a significant amount of user perceived latency. The time that DNS resolution takes is highly variable.  Latency delays range from around 1ms (locally cached results) to commonly reported times of several seconds.</p>
<p>DNS prefetching is an attempt to resolve domain names before a user tries to follow a link. This is done using the computer’s normal DNS resolution mechanism. Once a domain name has been resolved, if the user does navigate to that domain, there will be no effective delay due to DNS resolution time. When we encounter hyperlinks in pages, we extract the domain name from each one and resolving each domain to an IP address.  All this work is done in parallel with the user’s reading of the page, using minimal CPU and network resources.  When a user clicks on any of these pre-resolved names, they will on average save about 200 milliseconds in their navigation (assuming the user hadn’t already visited the domain recently). More importantly than the average savings, users won’t tend to experience the “worst case” delays for DNS resolution, which are regularly over 1 second.</p>
