Preload Critical Scripts for Faster Interactivity

Performance Analyzer

What is this warning?

An important script is being discovered late in the page load process, which can delay when your page becomes interactive. By 'preloading' the script, you can tell the browser to start downloading it much earlier, ensuring it's ready to be used the moment it's needed.

How to Fix This Issue

How to Fix It

The Problem

A key JavaScript file required for initial functionality is loaded without being prioritized.

The Solution

Add a `<link rel="preload">` tag for the critical script in the <head> of your HTML.

<link rel="preload" href="/js/critical-app-logic.js" as="script">

Why This Works

Preloading gives you more control over the loading priority of your resources, ensuring that the most important files are fetched first. This can significantly improve your Time to Interactive (TTI) metric.
