CLOUDFLARE has introduced a new Worker template for Vertical Microfrontends (VMFE), enabling teams to map multiple independent Cloudflare Workers to a single domain and ship marketing, docs, and dashboards as one cohesive application. Vertical microfrontends differ from horizontal architectures by owning an entire vertical stack for a route, defined by URL paths such as /, /docs, and /dash, with each path mapping to its own Worker and CI/CD.
The approach aims to deliver visually unified experiences through techniques like CSS view transitions and document preloading, while ensuring teams do not leak internal implementation details. A Router Worker at the edge handles request routing, using service bindings to forward requests to specific frontends and HTMLRewriter to adjust absolute paths in responses, so assets are accessible whether via the Router or directly.
Developers can configure routes and bindings in a wrangler definition and router logic, allowing path prefixes like /docs or /dash to be forwarded to corresponding Workers, creating a seamless multi-frontend experience at the edge.
