vercel-microfrontends
Guide for building, configuring, and deploying microfrontends on Vercel. Use this skill when the user mentions microfrontends, multi-zones, splitting an app across teams, independent deployments, cross-app routing, incremental migration, composing multiple frontends under one domain, microfrontends.json, @vercel/microfrontends, the microfrontends local proxy, or path-based routing between Vercel projects. Also use when the user asks about shared layouts across projects, navigation between microfrontends, fallback environments, asset prefixes, or feature flag controlled routing.

Vercel Microfrontends
Split a large application into independently deployable units that render as one cohesive app. Vercel handles routing on its global network using microfrontends.json.
Core concepts: default app (has microfrontends.json, serves unmatched requests) · child apps (have routing path patterns) · asset prefix (prevents static-asset collisions) · independent deployments.
Frameworks: Next.js (App Router + Pages Router), SvelteKit, React Router, Vite — all via @vercel/microfrontends.
CLI: microfrontends proxy (local dev proxy) · microfrontends port (print auto-assigned port).

This skill includes detailed reference docs in the references/ directory. Do not read all references upfront. Instead, search or grep the relevant file when the user asks about a specific topic:
| Topic | Reference file |
|---|---|
Getting started, quickstart, framework setup, microfrontends.json schema, fields, naming, examples |
references/configuration.md |
| Path expressions, asset prefixes, flag-controlled routing, middleware | references/path-routing.md |
| Local proxy setup, polyrepo config, Turborepo, ports, deployment protection | references/local-development.md |
| Adding/removing projects, fallback environments, navigation, observability | references/managing-microfrontends.md |
Testing utilities (validateMiddlewareConfig, validateRouting, etc.), debug headers, common issues |
references/troubleshooting.md |
| Deployment protection, Vercel Firewall, WAF rules for microfrontends | references/security.md |
When the user asks about a specific topic, use grep or search over the relevant reference file to find the answer without loading all references into context.
