Prefetching and Preloading Micro Frontends
Learn how to anticipate user navigation and fetch micro frontend bundles ahead of time to make transitions feel instant.
From Lazy to Eager-ish
Lazy loading saves the initial load but adds a wait when the user first visits an MFE. Prefetching closes that gap by fetching likely-needed bundles in advance.
Prefetch vs Preload
The browser offers two hints:
- preload: fetch now, high priority, needed soon
- prefetch: fetch when idle, low priority, maybe needed later
