Building vertical microfrontends on Cloudflare’s platform

Summary

The article introduces a new Worker template for Vertical Microfrontends (VMFE) on Cloudflare, allowing teams to independently manage different parts of an application by associating specific Cloudflare Workers with URL paths. This approach contrasts with traditional horizontal microfrontend architectures by enabling teams to own the entire stack for their designated routes, including frameworks, libraries, and CI/CD pipelines. The article discusses the challenges of integrating these microfrontends into a cohesive user experience and presents solutions such as CSS View Transitions and Speculation Rules to enhance navigation fluidity and performance. Additionally, it covers the implementation of a Router Worker to manage request routing and HTML rewriting for seamless integration of various microfrontends.

Key Learnings

• 1Vertical microfrontends allow teams to own entire application slices, improving autonomy and reducing regression risks.
• 2CSS View Transitions can create a unified user experience across different microfrontend projects, making navigation feel seamless.
• 3Speculation Rules can enhance performance by prefetching resources, making transitions between microfrontends feel instantaneous.
• 4A Router Worker can effectively manage request routing and HTML rewriting, ensuring that asset paths are correctly resolved for proxied requests.
