NextCompile (Cloudflare runtime)

in-progress

The 13-phase Go compiler that turns a Next.js standalone build into an ESM Cloudflare Worker — vendored RSC runtime, Server Actions, middleware, image optimization. Active development; see roadmap for what works.

Source reference: shared/nextcompile/ (Go pipeline + JS runtime in runtime_src/), NEXTCOMPILE_ROADMAP.md

Why a compiler instead of a bridge

TODO Workers cannot spawn Node — must compile to ESM with workerd-friendly imports.

The 13-phase pipeline

TODO list each phase — detect, scan, vendor RSC, derive bindings, elide dead routes, emit manifest, etc.

Runtime modules (runtime_src/)

TODO dispatcher.mjs, context.mjs, rsc.mjs, actions.mjs, cache.mjs, image.mjs — what each owns.

Working today

TODO API routes, /public from R2, Server Actions (CSRF + JSON), pure-server RSC pages, image optimization, basic revalidate.

Not working yet

TODO "use client" components in RSC pages, Suspense streaming, scheduled() exports, full middleware semantics, Hyperdrive injection.

Phased roadmap

TODO auto-provisioning (priority 1), client-reference manifests, layout composition, HTML shell streaming, error boundaries, parallel routes, PPR.

Trying it

TODO how to opt in for experimentation, expected sharp edges.

Contributing

TODO where the bar is — runtime_src changes need parity tests against fixture apps.
