OpenNext for Cloudflare

Deploy Next.js apps to Cloudflare!

OpenNext for Cloudflare is Cloudflare specific adapter that enables deployment of Next.js applications to Cloudflare.

Getting started

You can use create-next-app to start a new application or take an existing Next.js application and deploy it to Cloudflare using the following few steps:

Configure your app

• add the following devDependencies to the package.json:

  npm add -D wrangler@latest @opennextjs/cloudflare
  # or
  pnpm add -D wrangler@latest @opennextjs/cloudflare
  # or
  yarn add -D wrangler@latest @opennextjs/cloudflare
  # or
  bun add -D wrangler@latest @opennextjs/cloudflare

• add a wrangler.toml at the root of your project

  #:schema node_modules/wrangler/config-schema.json
  name = "<your-app-name>"
  main = ".worker-next/index.mjs"
  
  compatibility_date = "2024-09-23"
  compatibility_flags = ["nodejs_compat"]
  
  # Use the new Workers + Assets to host the static frontend files
  assets = { directory = ".worker-next/assets", binding = "ASSETS" }

You can enable Incremental Static Regeneration (ISR) by adding a KV binding named NEXT_CACHE_WORKERS_KV to your wrangler.toml:

• Create the binding

  npx wrangler kv namespace create NEXT_CACHE_WORKERS_KV
  # or
  pnpm wrangler kv namespace create NEXT_CACHE_WORKERS_KV
  # or
  yarn wrangler kv namespace create NEXT_CACHE_WORKERS_KV
  # or
  bun wrangler kv namespace create NEXT_CACHE_WORKERS_KV

• Paste the snippet to your wrangler.toml:

  [[kv_namespaces]]
  binding = "NEXT_CACHE_WORKERS_KV"
  id = "..."

[!WARNING] The current support for ISR is limited.
