@cloudflare/next-on-pages
Reference:
Quick Start
-
npx create-next-app@latest my-app
Note that if you elect to use eslint, there are a couple of places you need to add return types to make the default template pass the pre-build checks.
-
cd
into 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.ts
with the following:
import type { NextRequest } from "next/server";
export const config = {
runtime: "experimental-edge",
};
export default async function handler(
req: NextRequest
): Promise<Response> {
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 commit
and git push
to 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-minify |
Build output directory | .vercel/output/static |
-
Add a NODE_VERSION
environment variable set to 14
or greater.
-
In the Pages project Settings > Functions > Compatibility Flags, add the transformstream_enable_standard_constructor
and streams_enable_constructors
flags. These will not be necessary once they graduate to be on by default on 2022-11-30's compatibility date.
-
The project should now be ready to deploy. Create a new deployment.
