This Google form is the best place for requests to raise that limit: https://docs.google.com/forms/d/e/1FAIpQLSe4N0BjIxu9AuissCAtYjXUovViXmdx2zopjzASaJi_SImJsw/viewform?usp=send_form

Appreciate you trying out Pages and functions!

Functions Limit Increase on Cloudflare Pages

If you have hit your limit for invocation requests while deploying your functions on Cloudflare Pages, you can submit this form to our team to learn more about your use case. Please provide the information below in case we need to chat with you more about raising the limit.

Please note: this limit increase is only applied to Functions deployed...

@gregbrimble perfect, one form I hadn't filled out yet.

Ggerred so there's no functional difference between _worker.js and all of the functions

GregBrimble•11/20/21, 10:04 PM

We might change it, so don't rely on this behavior, but yeah, they're pretty functionally similar at the moment.

functions

functions

gives you simple routing behavior and an arguably easier API, but they boil down to the same thing at the moment.

gerred•11/20/21, 10:05 PM

@gregbrimble Does the separated Routes -> workers feature do the same thing functionally as well?

gerred•11/20/21, 10:05 PM

i.e. is there an optimization path to be had today on my end?

HHockey I will say, for predominantly static websites like a Jekyll blog, that would def...

GregBrimble•11/20/21, 10:07 PM

Absolutely. But bear in mind folks, that this is no worse than what Workers Sites does today. We'll absolutely be trying to figure out when we can know the request isn't anything functions-y, but we just don't have the answers right now.

itsmatteomanfOP•11/20/21, 10:08 PM

You mean deploying a separate Worker?

GregBrimble•11/20/21, 10:10 PM

Normal Workers will only be invoked if the incoming request matches the route you set.

GregBrimble•11/20/21, 10:10 PM

But seriously, if you're trying to use functions and are concerned about that limit, we'll just raise it for you!

GregBrimble•11/20/21, 10:11 PM

Definitely don't want that being a concern for you trying out functions and giving us vital feedback

Iitsmatteomanf You mean deploying a separate Worker?

gerred•11/20/21, 10:11 PM

er, to be a little more specific (thank you for answering on your weekend!) - with regular workers Routes, do all of those, from a "total size of isolate" perspective get compiled down the same way? and even with the goal to shrink cold starts, is there a benefit today to, with multiple routes, splitting out those workers?

gerred•11/20/21, 10:11 PM

what got me asking about that was how pages functions works today under the hood.

gerred•11/20/21, 10:12 PM

is that a generalizable model, I suppose.

gerred•11/20/21, 10:12 PM

I feel like I'm generating out some big isolates locally, but maybe not.

jersey•11/20/21, 10:12 PM

assuming I have a pages function at

functions/api/lookup.js

functions/api/lookup.js

I could request it from

/api/lookup

/api/lookup

, right?

GregBrimble•11/20/21, 10:12 PM

Oh, no. Normal Workers are very much their own thing, and they aren't combined in any funky ways whatsoever.

Ggerred er, to be a little more specific (thank you for answering on your weekend!) - wi...

itsmatteomanfOP•11/20/21, 10:12 PM

Technically it's the opposite, the more you combine, the less chances the Worker is cold. But cold starts aren't really that big of an issue on paid plans, if at all.

gerred•11/20/21, 10:12 PM

OH that's a fair point. and yeah, but as we're looking at moving over, we're pulling in some large WASM bits - hopefully eventually we can drag those out from R2, but we're early in this process.

itsmatteomanfOP•11/20/21, 10:13 PM

The optimization is, the bigger it gets, the more time it takes to parse and execute (not much, it's still V8 and it's very fast), but a 1kB worker vs. a 1MB worker has different parse times.

GregBrimble•11/20/21, 10:13 PM

It's what HTMLRewriter was built for, but you can definitely do it yourself if you prefer:

response = await fetch()
text = await response.text()
text += '<h1>Hello</h1>'
return new Response(text)

response = await fetch()
text = await response.text()
text += '<h1>Hello</h1>'
return new Response(text)

itsmatteomanfOP•11/20/21, 10:13 PM

-> HTMLRewriter.

GregBrimble•11/20/21, 10:14 PM

HTMLRewriter will give you better performance.

itsmatteomanfOP•11/20/21, 10:14 PM

Also, note to everyone. The employee here is @gregbrimble, I'm not

GregBrimble•11/20/21, 10:15 PM

gerred•11/20/21, 10:15 PM

totally, I'm trying not to use the embedding of v8 we've written at my startup unless it's on our clients' hardware (so basically, move our backend over to workers if we can), i've been deep in this "hell" (not really hell, but it's intricate obviously)

gerred•11/20/21, 10:15 PM

the clarification there suggests though for us I should have a separate API set of workers from what we would do with pages for the auth/etc parts of the service.

gerred•11/20/21, 10:16 PM

GregBrimble•11/20/21, 10:17 PM

If your site has static assets, and you're wanting to deploy everything together, then full-stack Pages is what I'd recommend going with.

If it makes sense for your application, stick with the

functions

functions

dir handlers. _worker.js_worker.js is a primarily an escape-hatch for either people with existing Workers, or framework authors.

gerred•11/20/21, 10:17 PM

@gregbrimble that makes sense, thank you.

MMark Hood I wasn’t aware that was needed… back to the docs I go! Thanks for the advice.

itsmatteomanfOP•11/20/21, 10:17 PM

The docs for wrangler@betawrangler@beta aren't great, but it's betabeta after all. Look at @gregbrimble's stream at https://twitch.tv/gregbrimble

GregBrimble•11/20/21, 10:17 PM

If you need stability though, Workers have been around since (I think) 2017, so are a lot more mature than the beta Pages functions

MMark Hood I wasn’t aware that was needed… back to the docs I go! Thanks for the advice.

GregBrimble•11/20/21, 10:18 PM

npx wrangler pages dev --helpnpx wrangler pages dev --help should give you all the options you have available

gerred•11/20/21, 10:18 PM

oh yeah, that I'm familiar with! just for the first time this has all come together in a way I think we can fully put something together and drop a crap ton of tools. nice work.

GregBrimble•11/20/21, 10:19 PM

Cool. You want that available on the homepage or on /weather/weather?
