BWe have an API which ingests images from the user and stores them in an R2 bucket. One part of that API which is hard to implement on the Workers platform is image transformation and validation. Use-cases such as
- transforming the image on ingest to compress and shrink to a certain max resolution
- validating image dimensions (must be 128x128px for example)
Does anyone have any experience or recommendations with these use-cases?
We used which cannot run on Workers. Perhaps could use but it's probably costly on CPU and Workers have limited memory. Cloudflare Images seems to be more about serving images with transformations, rather than transforming/validating on ingest via a worker (would prefer to store a single minified image in R2)?

MHi, the feature matrix for "workers vs. pages" says that middleware isn't supported and to use service bindings. But how does that help to secure a *.workers.dev Url? That's an url I don't control, but I still want basic auth for those...
WWe recommend disabling workers.dev or putting Access on it
MI'm trying to achieve that somehow but the options seem very limited because "Workers which have static assets cannot be routed on a URL which has a path component".. so essentially I would need an entire custom domain just to have my worker for assets available anywhere. Half the problem might be that Cloudflare Access is probably overkill even if I do get access for that on the company account
AYour Wrangler version is very out of date - I had a similar problem, I think even now local service bindings are experimental - but I’d try updating to the latest version of Wrangler as a first step
HUsing a Router?
HAny router
HAt least I know Hono and Itty could do that
AHey! 
I am looking to expose prometheus metrics out of my workers.
What could be the best way for this?
?
I am looking to expose prometheus metrics out of my workers.
What could be the best way for this?
- have DO that stores the metrics. And expose the metrics on another /metrics worker
- use analytics engine to store the metrics, and expose them on another /metrics worker
- build recorded queries on top of logs with something like Loki?
?ABasically I want to end up with otel metrics like:
Wi love Analytics Engine, prefer that over doing Prometheus in a DO
Wbut you can hack promjs to run in a DO and serve - others have done this before
AWhy would you prefer AE over Prom in a DO?
Aand I guess Prom in a DO means saving the state of a counter in the DO 
0how you all do logging for production debugging in worker?
0the free plan doesnt do much
AIs there an issue with worker CI/CD builds? This happened yesterday and it's happening to me again, but all of my workers build statuses are just "Queued" even though there are no builds running.
A^ I believe I've found a bug with Workers CI/CD, what's the best place to report that? (I was able to reproduce the issue, and it seems related to my setup and how Workers CI is triggered)
Ccan anyone please advice related to custom domains. I'm trying to create a sass king of app.
- I managed to create tenant wildcard subdomains by using pages and a custom proxy worker.
- I added the custom domain on my side
- tenant added CNAME servicii.cmnstmntm.com -> ionica.app.greatoutdoors.live
Cis this even possible with my plan? i assumed it is since i could add the custom domain
CDo you have a wildcard catch-all route? https://developers.cloudflare.com/cloudflare-for-platforms/cloudflare-for-saas/start/advanced-settings/worker-as-origin/.
Unproxied CF For SaaS hostnames come through as the actual hostname, ex it's looking for a worker route matching and Worker Custom Domains just won't work
Be careful not to break your existing subdomains/domain with that. I usually recommend people get a separate domain just for customer custom domains to avoid issues with that and the fact that all custom hostnames inherit your zone's configuration (waf rules, config rules, network settings, etc), so better to eliminate the possibility of non-intentionally changing settings for them/more flexibility with your custom domains

Learn how to use a Worker as the fallback origin for your SaaS zone.
Cyes, the worker has a pattern like this
Cso i need a worker that handles the origin specifically
Cthanks @Chaika i'll give it a try
Cno that's not a wildcard catch-all (well, not as wide as CF For SaaS needs)
C is a wildcard catch-all
Csounds like you might have figured out the rest but yea, you need an actual full wildcard
AHi, I have a worker that somehow can't connect to a D1 datbase using Prisma, but it works locally. What would be you recommendation on debugging this? I just see "Internal Server Error"

THello everyone
I have a static maintenance mode html page that is stored in Worker KV, which is only displayed to users whose ip address is not in the whitelist. I'm trying to replace some text in my html file stored in Worker KV with Worker
Here is a part from my html file
I want to replace the word “Loading...” with the ip address of my user
I have a static maintenance mode html page that is stored in Worker KV, which is only displayed to users whose ip address is not in the whitelist. I'm trying to replace some text in my html file stored in Worker KV with Worker
Here is a part from my html file
<section>
<h2>Your IP Address: <span id="user-ip">Loading...</span></h2>
</section>
I want to replace the word “Loading...” with the ip address of my user
THere's a script example from my Worker where I'm trying to replace
async function handleFetch(event) {
let ip = event.request.headers.get('cf-connecting-ip');
let customersIPsRangesJson = await $(cloudflare_kv_name).get('$(employee_ip_range_key)', 'json') || [];
const isIPInRange = customersIPsRangesJson.some(range => {
return range && range.includes('-') && checkIPInRange(ip, range);
});
if (isIPInRange) {
return fetch(event.request);
} else {
return handleEvent(event, ip);
}
}
class TextRewriter {
constructor(newText) {
this.newText = newText;
}
element(element) {
const newContent = <span id="user-ip">${this.newText}</span>;
element.replace(newContent, { html: true });
}
}
async function handleEvent(event, ip) {
try {
if (DEBUG) {
// customize caching
options.cacheControl = {
bypassCache: true,
};
}
const page = await getAssetFromKV(event, options);
const response = new Response(page.body, page);
// allow headers to be altered
response.headers.set("X-XSS-Protection", "1; mode=block");
response.headers.set("X-Content-Type-Options", "nosniff");
response.headers.set("X-Frame-Options", "DENY");
response.headers.set("Referrer-Policy", "unsafe-url");
response.headers.set("Feature-Policy", "none");
// Using HTMLRewriter to insert the IP address
const rewriter = new HTMLRewriter()
.on('span#user-ip', new TextRewriter(ip));
return rewriter.transform(response);
}
TAs you can see, I'm trying to get the ip from the > async function handleFetch(event) using the command let ip = event.request.headers.get('cf-connecting-ip');
Unfortunately, I cannot replace the word “Loading...” with the ip address, maybe you can help me with this, I will be very grateful
PS. I apologize in advance for any discrepancies in my explanations, I'm actually still quite new to Cloudflare Workers, and JS in general)

C@Chaika but now if i try to redirect to a different worker address, is giving the same timeout
CWorkers can't fetch Workers on the same zone/domain
CUse Service Bindings
Chttps://developers.cloudflare.com/workers/runtime-apis/bindings/service-bindings/ faster & cheaper too, not paying for requests
CThey're pushing RPC which is cool but would maybe require code changes, you can just use normal http/fetch: https://developers.cloudflare.com/workers/runtime-apis/bindings/service-bindings/http/ too

Cwow, how cool is that
GHi! There is limit of maximum static assets files inside the new product « Workers with assets » ?
Pages have a hardware limit of 20,000 files maximum
Pages have a hardware limit of 20,000 files maximum
CSame as Pages workers-and-pages-discussions
C@Chaika it looks that at some point (in the proxy worker) i have to fetch the Astro page ..
Cor a better solution would be to get rid of pages, and use astro as a worker .. but this comes with it's own limitations
CI didn't think that implementing custom domains could be so difficult

MHas anyone tried a canvas package on the latest Workers compatibility? node-canvas, napi-rs/canvas, etc. I assume it doesn't work
On a relevant note, is there any reality in which one of those packages would/could ever work directly on Workers without needing any external service or browsing?

HSort of? At the moment, if a route has an asset that matches the path exactly, then that asset will be served. One way to get around this is to put the assets in a different directory( maybe)
