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 (vercel microfrontends / vercel mf):

• create-group — create a new group; interactive by default, or fully non-interactive with --non-interactive (options: --name, --project (repeatable), --default-app, --default-route, --project-default-route (repeatable, format: <project>=<route>, required for each non-default project in non-interactive mode), --yes to skip confirmation prompt); note: --non-interactive is blocked if adding the projects would exceed the free tier limit — the user must confirm billing changes interactively
• add-to-group — add the current project to an existing group; requires interactive terminal (options: --group, --default-route)
• remove-from-group — remove the current project from its group; requires interactive terminal (option: --yes skips project-link prompt only)
• delete-group — delete a group and all its settings, irreversible; requires interactive terminal (option: --group to pre-select group)
• inspect-group — retrieve group metadata (project names, frameworks, git repos, root dirs); useful for automating setup (options: --group, --format=json, --config-file-name)
• pull — pull remote microfrontends.json for local development (option: --dpl)
• microfrontends proxy — local dev proxy · microfrontends port — print auto-assigned port
