Reference:
-
npx create-next-app@latest my-app -
cdinto the new directory (e.g.cd my-app) -
npm install -D @cloudflare/next-on-pages vercel -
Configure the project to use the Edge Runtime:
-
Replace
pages/api/hello.jswith the following:// Next.js Edge API Routes: https://nextjs.org/docs/api-routes/edge-api-routes export const config = { runtime: "experimental-edge", }; export default async function (req) { return new Response(JSON.stringify({ name: "John Doe" }), { status: 200, headers: { "Content-Type": "application/json", }, }); }
-
Add the following to
next.config.js:/** @type {import('next').NextConfig} */ const nextConfig = { + experimental: { + runtime: "experimental-edge", + }, reactStrictMode: true, swcMinify: true, }; module.exports = nextConfig;
-
-
git commitandgit pushto a GitHub/GitLab repository. -
Create a Pages project, connect that repository, and select "Next.js" from the framework preset list.
Option Value Build command npx @cloudflare/next-on-pages --experimental-minifyBuild output directory .vercel/output/static -
Add a
NODE_VERSIONenvironment variable set to14or greater. -
In the Pages project Settings > Functions > Compatibility Flags, add the
transformstream_enable_standard_constructorandstreams_enable_constructorsflags. These will not be necessary once they graduate to be on by default on 2022-11-30's compatibility date. -
