I'm trying to get cache headers working for images loaded with custom loader which utilizes the default Cloudflare Image Optimization implementation. These files are served from the public folder (

public/images

public/images

public/images

public/images) which by default gets no cache (

public, max-age=0, must-revalidate

public, max-age=0, must-revalidate

public, max-age=0, must-revalidate

public, max-age=0, must-revalidate) and so the optimizer serves them with this header as well.

I've tried to add the following config settings:

{
  async headers() {
    return [
      {
        source: '/cdn-cgi/image/(.*)', // does not work
        headers: [
          {
            key: 'cache-control',
            value: 'public, max-age=14400',
          },
        ],
      },
      {
        source: '/images/(.*)', // does not work
        headers: [
          {
            key: 'cache-control',
            value: 'public, max-age=14400',
          },
        ],
      },
    ];
  },
  images: {
    minimumCacheTTL: 3600, // this does nothing
    loader: 'custom',
    loaderFile: './imageLoader.js',
  },
}

{
  async headers() {
    return [
      {
        source: '/cdn-cgi/image/(.*)', // does not work
        headers: [
          {
            key: 'cache-control',
            value: 'public, max-age=14400',
          },
        ],

      {

          },
        ],
      },
    ];
  },
  images: {
    minimumCacheTTL: 3600, // this does nothing
    loader: 'custom',

}

{

        headers: [
          {
            key: 'cache-control',
            value: 'public, max-age=14400',
          },
        ],
      },
      {
        source: '/images/(.*)', // does not work
        headers: [
          {
            key: 'cache-control',
            value: 'public, max-age=14400',
          },

    ];
  },
  images: {
    minimumCacheTTL: 3600, // this does nothing
    loader: 'custom',
    loaderFile: './imageLoader.js',
  },
}

I also tried adding them to

_headers

_headers

_headers

_headers file in the root of the project but they don't seem to get included in the final build.

Only way I've been able to get cache headers working for these files is by modifying

./.vercel/output/static/_headers

./.vercel/output/static/_headers

./.vercel/output/static/_headers

./.vercel/output/static/_headers after the build by adding this to the end of the generated file:

/images/*
  cache-control: public,max-age=3600

/images/*
  cache-control: public,max-age=3600

/images/*
  cache-control: public,max-age=3600

/images/*
  cache-control: public,max-age=3600

Am I missing something or is this the only way to get cache headers working for these images?

Hey there

I currently have a website on Vercel and the main reason we chose Vercel was due to how easy it was to set up a multi tenant system (we allow our "Pro" users to attach a domain to their profile and it's as simple as letting them point either a root domain to the Vercel IP, or a CNAME to their subdomain (username.website.com)).

I'd like for us to move back to Cloudflare tbh, as I have never been a big fan of Vercels pricing model (even before the recent changes), but I'm stuck at a loss of understanding how we could set something like this up on Cloudflare, as it's quite confusing regarding the "edge certs/client certs/custom hostnames/origin server etc.

Is there any documentation/posts/resources to help point me in the right direction? Right now the routing is just going through the middleware.ts and Vercel pretty much take care of the rest.

TIA!

N

neoney•4/21/24, 11:55 AM

I believe all you need is a CNAME pointed to your pages subdomain and adding the domain in the project's settings

N

neoney•4/21/24, 11:55 AM

You can add it using the API too

Hey guys, I am struggling with 'jose' for JWT signing and verification of tokens. I am writing a Next.JS app for cloudlfare pages, previously I had it statically generated and used Cloudflare's functions as the backend, but since I switched to next-on-pages, the cloudflare functions stopped working, so I had to refactor the entire "backend" to use Next.js API routes instead. The problem here is that once I switched to Next.JS API routes, I had to refactor the cloudflare functions middleware (which was responsible for authorization) into Next.JS API middleware, now after I did that the previously used library: @tsndr/cloudflare-worker-jwt stopped working, so I had to find a new one. The alternative that I found was 'jose' https://www.npmjs.com/package/jose. This is how I am using it to sign and verify a JWT:
Singing:
///////////
const JWT_SECRET = env.JWT_SECRET
const secret = new TextEncoder().encode(JWT_SECRET)
const alg = 'HS256'
const token = await new jose.SignJWT({
id: _id
})
.setProtectedHeader({ alg })
.setIssuedAt()
.setIssuer('urn:test')
.setAudience('urn:test-audience)
.setExpirationTime('15m')
.sign(secret)

Verifying:
///////////
await jose.jwtVerify(token, secret, {
issuer: 'urn:test',
audience: 'urn:test-audience',
})

The token and secret used in the verifying step are the same as in the signing.

The problem I have here is that the verifying fails with this message:
[JWSInvalid: Invalid Compact JWS] {
code: 'ERR_JWS_INVALID',
name: 'JWSInvalid'
}

Even though I try to verify the token immediately after I create it (I try this for debugging purposes).
If someone encountered a similar issue and can help me, I will be very grateful. Thank you and sorry for the long post.

matiasjMusante•4/22/24, 4:32 PM

Hello, I've been trying unsuccessfully to modify the cache behavior in my fetch requests using Next.js (next-on-pages, for example, in route.js:

export const runtime = 'edge'
import { revalidatePath } from 'next/cache'

export async function GET() {
// revalidatePath('/api'); REVALIDATE PATH DOES WORK.
const res = await fetch('https://postgrest-2n44.onrender.com/todos')
const data = await res.json()
return Response.json(data)
}

As you can see in the comments, revalidatePath does update the data obtained through the fetch.

But when I try to include, for example, "native" Next.js options, such as including {"cache: no-store"} in the fetch request, I receive the error:

Error: The 'cache' field on 'RequestInitializerDict' is not implemented. cloudflare

I also tried with headers (cache-control, etc.) and with next: revalidate x.
Am I doing something wrong or misunderstanding something? Thank you very much.

Does anyone have pointers for clearing fetch cache properly when hosting a Nextjs (app router with SSR) on Cloudflare? I'm noticing when testing my pages from various locations/browsers that data is often out of sync. I've been using

revalidateTag

revalidateTag

revalidateTag

revalidateTag to clear fetch cache and it works ~80% of the time. I've narrowed the issue down to locations. If you access the web page from a distant location (via VPN) the data is "stuck" on an older version. Almost like the data cache isn't clearing and propagating, so when accessing the page remotely it loads instantly (seemingly via cache) since it doesn't know about fresh data.

I've posted about this in the community forums (https://community.cloudflare.com/t/nextjs-serving-stale-old-fetch-cache-across-network-how-to-clear-cache/646169/2) but thought I'd try here as well.

I think you may try with any cache busting technique, so to avoid completely the cache.

"Cache busting is a technique used in web development to ensure that the latest version of a file is fetched from the server, bypassing cached versions. By appending a unique identifier like a version number or timestamp to the file’s URL, the browser treats it as a new resource, fetching the most up-to-date version. This technique prevents users from seeing outdated cached content and improves the overall user experience."

You may, for example, include the timestamp somewhere in the fetch req. so it will be a unique request.

Why are you using revalidateTag? I myself coudnt make options like (cache : "no-store) work, but revalidatePath/revalidateTag, seemed to work... is the same happening to you?

SM•4/23/24, 11:36 AM

I'm NOT looking to bypass cache on every request. I want my Nextjs app to fetch new data when cache has been invalidated (via

revalidateTag

revalidateTag

revalidateTag

revalidateTag) and after a stale request has been made. Then, after a fetch, it should cache again. This is standard nextjs functionality and has worked me on Vercel.

Like I said, it's kind of working as expected. But it's not 100% reliable. Old data is appearing in various places (locations/browsers) then getting stuck. So a timestamp won't fix this cos it might make nextjs fetch new data every-time. I don't want that.

I've been using

revalidateTag

revalidateTag

revalidateTag

revalidateTag for years on Vercel. It works great and is a modular way to manage data cache.

The site in question is a news website. Think of it like a blog. You have an index (home) with post titles/summaries, then you have the post pages. What's happening is: a new post is added, I programmatically call

revalidateTag

revalidateTag

revalidateTag

revalidateTag with relevant tags. I then view the page on my browser and refresh it shows the latest post titles on the home page and correct post titles. However, browsers in other locations show old data (even after refresh). And the old data is staying for days. My fetch revalidate is only set to

300

300 seconds (5mins).

It's almost like Cloudflare worker/pages aren't spreading data updates across the rays (datacenter's). As though each ray stores it's own instance of

.next

.next

.next

.next cache. Surely that's not right? Even if it were right, you'd need a way to invalidate cache across all of it, on demand. But I can't find that anywhere.

Sorry to ramble, just hoping I've missed something obvious that's maybe Cloudflare specific.

matiasjMusante•4/23/24, 6:19 PM

IF cache busting solves it, you could as well make a custom implementation and call it when/where you need it. I mean, revalidating would give the same effects than creating a "new" fetch (by adding timestamp somewhere, route or headers). Hope someone may explain all this a little bit more or give some clarification/solution (I myself can´t make the cache: no store option to work, and found that only revalidatePath/Tag are the only ways to revalidate a fetch made inside an nextjs project on nexat-on-pages).

Was investigating to find out why my site was slow in some pages, then today I finally found out why. For some reason making CF cache resulting pages at the edge (by using a Cache Rule) doesn't play well with page streaming: the page is returned only when Next is done rendering the whole page, so TTFB becomes a second and a half instead of milliseconds. Is this a known issue? Is there a config I can operate to have both CF cache and page streaming when not primed?

Oosa Are you using the Workers KV for caching? https://github.com/cloudflare/next-on-...

You are a bloody legend. This fixed every weird cache issue we were facing

Can't thank you enough. I owe you a beer/coffee. Seriously. I think this is important information for Nextjs devs coming from Vercel where distributed, fast caching is the norm, so I've suggested an edit to the framework guide (https://github.com/cloudflare/cloudflare-docs/issues/14231).

getRequestContext()

getRequestContext() on the edge and I can only set

export const runtime = "edge";

export const runtime = "edge";

within an api route, right? (Nextjs 14)

that's not true, you can export that const in a layout file and that will affect all pages within it

actually I do export that const in various places like my D1 functions folder

my CPU time on my next.js site hosted on cf pages seems high, is this normal? The functions aren't a
