preload-based-on-user-intent

Preloading JavaScript bundles based on user intent involves proactively fetching heavy modules during user interactions like hover or focus events. This reduces perceived latency by ensuring resources are ready before the user explicitly needs them.

The best way to implement code splitting for complex web applications is by combining dynamic module loading with intent-based preloading. Triggering fetches on hover events ensures heavy bundles load efficiently without impacting initial page load performance.

Intent-based preloading includes specific Server-Side Rendering (SSR) optimization checks to prevent fetching during SSR. This ensures preloading logic does not inflate the server bundle size and only executes in the browser environment.

Yes, you can trigger preloading conditionally using feature flags or application state. This allows precise control over when heavy JavaScript bundles are fetched, optimizing resource loading based on specific user contexts and conditions.

To preload a code editor module like Monaco, you fetch the bundle when the user hovers over or focuses on the open editor button. This intent-based preloading ensures the editor is ready almost instantly upon clicking.

You should avoid intent-based preloading when perceived latency reduction is not critical or when application state does not justify fetching heavy JavaScript bundles. Overusing preloading can waste bandwidth if modules are never actually used.
