Quicklink: Faster Subsequent Page-Loads by Prefetching

2025-09-11

Website owners and developers can significantly improve user experience by reducing page load times. Quicklink is a lightweight JavaScript library designed to achieve this by prefetching in-viewport links during idle time, resulting in faster subsequent page-loads.

Quicklink is a drop-in solution that automatically prefetches URLs for links within the user's viewport. With a minimal size of less than 1KB when minified and gzipped, it is an efficient addition to any website. The library is particularly beneficial for multi-page sites and can be integrated into single-page applications (SPAs) using popular frameworks like React.

Key Features and Usage

  • Automatically prefetches links in-view during idle time.
  • Highly customizable with options to limit prefetching based on specific DOM elements, total requests, or concurrency limits.
  • Supports manual prefetching of custom URLs.
  • Easy integration with a simple script tag or ES module import.
  • Compatible with various frameworks, including React, with dedicated HOC (Higher-Order Component) for React applications.

Benefits

By implementing Quicklink, websites can achieve a substantial improvement in page transition speeds and overall user experience. For instance, NewEgg saw a 50% increase in conversions and 4x faster page transitions after implementing Quicklink.

Implementation

To start using Quicklink, simply include the script in your webpage and initialize it. The library can be customized to fit specific needs, such as prefetching links within a certain DOM element or limiting the number of prefetch requests. Detailed instructions and customization options are available on the Quicklink documentation.
