SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Preload helps ensure critical resources are requested early when they would otherwise be discovered late in the loading process, reducing latency for interactive moments.

Core Features & Use Cases

  • Preloads fonts, scripts, and images that the browser would otherwise fetch late in the waterfall to improve TTI and LCP.
  • Use case: apply preload hints to resources essential for the initial render, then verify improvements in user-perceived performance.

Quick Start

Preload the fonts and hero scripts that are discovered late to accelerate the first render.

Frequently Asked Questions about preload

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I preload fonts to improve Largest Contentful Paint?

Preloading critical web fonts uses link rel preload with the as attribute and crossorigin settings to fetch them early. This prevents late discovery in the loading waterfall, reducing latency and directly improving Largest Contentful Paint.

What is resource preloading for web performance?

Resource preloading is a technique that requests critical assets early before the browser discovers them late in the loading waterfall. It uses link rel preload to prioritize fonts, hero images, and key scripts to reduce Time To Interactive.

How do I preload hero images and key scripts for faster Time To Interactive?

Apply link rel preload hints to hero images and key scripts discovered late in the loading waterfall. This accelerates first render and reduces Time To Interactive across pages with dynamic resource discovery.

When should I use link rel preload for dynamic resource discovery?

Use link rel preload when critical resources like fonts or scripts are discovered late during dynamic resource discovery. Applying preload hints ensures these essential assets are fetched efficiently to improve user-perceived performance.

Does preloading critical assets require crossorigin settings for fonts?

Yes, when preloading fonts, use crossorigin settings with link rel preload. This ensures fonts are fetched efficiently without compatibility issues, reducing latency for interactive moments and improving load performance.

What is the best way to reduce Time To Interactive with preload hints?

The best way to reduce Time To Interactive is to apply preload hints to resources essential for initial render, such as fonts and hero scripts. This accelerates the first render and improves user-perceived performance across pages.
