Some problems from development to deployment

1. pnpm run build cause a error:

TypeError: fetch failed
    at Object.fetch (node:internal/deps/undici/undici:11457:11)
    at process.processTicksAndRejections (node:internal/process/task_queues:95:5) {
  cause: Error: connect ECONNREFUSED ::1:3000
      at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1494:16)
      at TCPConnectWrap.callbackTrampoline (node:internal/async_hooks:130:17) {
    errno: -61,
    code: 'ECONNREFUSED',
    syscall: 'connect',
    address: '::1',
    port: 3000
  }
}

Error occurred prerendering page "/todos". Read more: https://nextjs.org/docs/messages/prerender-error

Resolved:

reference: "Fetch failed" error in production mode

// src/app/todos/page.tsx
export const runtime = "edge"

2. After deployed process.env.[xxx] is undefined

Resolved:

// next.config.js
module.exports = {
+   env: {
+     DATA_API_KEY: process.env.DATA_API_KEY,
+     API_URL: process.env.API_URL,
+     GITHUB_TOKEN: process.env.GITHUB_TOKEN,
+   },
}

Vercel should also set some enviroment variables

go to set! ➡️

3. fetch api interface cause CROSS-ORIGIN error:

Resolved:

# More details see: src/middleware.ts
export function middleware(req: Request) {
  ...
+  const res = NextResponse.next()
+  if (origin && allowOrigins.includes(origin)) {
+    res.headers.appendif (origin && allowOrigins.includes(origin)) {
+    res.headers.append('Access-Control-Allow-Origin', origin);
+    // res.headers.append('Access-Control-Allow-Origin', '*') // replace this your actual origin
+  }
+  res.headers.append('Access-Control-Allow-Credentials', "true")
+  res.headers.append('Access-Control-Allow-Methods', 'GET,DELETE,PATCH,POST,PUT')
+  res.headers.append(
+    'Access-Control-Allow-Headers',
+    'X-CSRF-Token, X-Requested-With, Accept, Accept-Version, Content-Length, Content-MD5, Content-Type, Date, X-Api-Version'
+  )
+
+  return res
}

Redeploy.
