Incremental adoption of micro-frontends with Cloudflare Workers

This post discusses a technique called "fragment piercing" which allows developers to replace selected parts of a legacy client-side rendered application with server-side rendered fragments. The result is an application where the most important views are interactive sooner, can be developed independently, and receive all the benefits of the micro-frontend approach, while avoiding large rewrites of the legacy codebase. This technique is framework-agnostic and has been demonstrated using React, Qwik, and SolidJS. The "Productivity Suite" demo application showcases how different independent technologies can be used for both the legacy application and for each of the fragments.
