Next.js Image Optimization in Micro Frontend: The Complete Guide

Error: Invalid src prop (https://cdn.myapp.com/banner.jpg) on `next/image`,
hostname "cdn.myapp.com" is not configured under images in your next.config.js

You ship a product page. Every image 404s. The host's remotePatterns allowlists the CDN. The Products remote does not.

In a hybrid Next.js micro frontend, every Next.js app has its own images block, every block has its own allowlist, and a missed entry only surfaces on the specific remote that needed it.

The full guide covers:

• remotePatterns mirrored across host + every Next.js remote (and why)
• Local vs production configs: the single http://localhost line that must NEVER ship
• enableImageLoaderFix in NextFederationPlugin — the one-line fix for static images inside federated remotes
• AVIF + WebP format negotiation with real payload comparisons (180 KB → 61 KB, 66% smaller)
• deviceSizes + imageSizes tuning for your real rendered widths
• minimumCacheTTL trade-offs during active deploys
• The complete <Image> props guide: fill, sizes, priority, placeholder="blur", quality
• Eight production gotchas (with the actual error messages and fixes)
