[POC] Build Next.js app for cf workers

This monorepo includes a POC to see if it is possible to get a Next.js application built via next build (in standalone mode) to run in the Cloudflare workerd runtime.

Note

The code here is built based on the amazing work done by @mhart in https://github.com/mhart/nextjs-commerce

The repository

The repository contains two directories:

• nextjs-worker-builder containing a package that can be used to build Cloudflare workers compatible output from Next.js applications
• next-apps containing Next.js application that use the above mentioned builder (currently it only contains api-nodejs-hello-world)

How to try out/develop in the repository

Install the dependencies:

pnpm i

build the worker with:

pnpm --filter nextjs-worker-builder build

or in watch mode with:

pnpm --filter nextjs-worker-builder build:watch

build and preview the worker for the api-nodejs-hello-world application:

pnpm --filter api-nodejs-hello-world preview:worker

You can skip building the next app when it has not been modified:

SKIP_NEXT_APP_BUILD=true pnpm --filter api-nodejs-hello-world preview:worker
