About

The rel="preconnect" attribute on HTML <link> elements instructs browsers to establish early connections to external origins before resources are requested.

It is used to reduce latency by opening DNS lookup, TCP handshake, and TLS negotiation in advance for critical third-party domains such as CDNs, font providers, and analytics services.

Quicklink is an open-source JavaScript library from the Google Chrome team that speeds up subsequent page loads by prefetching links likely to be visited next.

It automatically detects links visible in the viewport, waits until the browser is idle, skips slow or data-saver connections, supports both prefetching and prerendering, and provides controls for request priority, throttling, allowed origins, and ignored URLs.
