I'm using sveltekit with functions (with adapter-auto so sveltekit endpoints are the functions now), but I am having trouble accessing env vars when testing locally. I am using wrangler:

wrangler pages dev --port 8788 --proxy 3000 --binding $(cat .env) -- svelte-kit dev

wrangler pages dev --port 8788 --proxy 3000 --binding $(cat .env) -- svelte-kit dev

However,

platform

platform

is always undefined in the endpoints. How can I fix this so I can access

platform.env

platform.env

while testing locally with wrangler2?

The code works fine in production when deployed to cloudflare. On the guide for setting it up, it says to use wrangler to test it locally, but

platform

platform

is always undefined: https://github.com/sveltejs/kit/tree/master/packages/adapter-cloudflare#environment-variables

Call

next()

next()

instead

James•5/29/22, 9:44 PM

context.next()

context.next()

in your example

James•5/29/22, 9:44 PM

Or you can

const file = await next()

const file = await next()

to get the response and then run an

HTMLRewriter

on top

maybe technically it could fail if KV or something is entirely down... but I wouldn't worry about it in your context

hi CF team,

if i POST via xhr on client side, will i be able to receive via onRequest on CF functions?

Original message was deleted

sumit•5/30/22, 5:35 PM

my main question was, xhr post works, right?

Original message was deleted

sumit•5/30/22, 5:39 PM

special reason = i already have xhr deployed so only little changes needed

BensTechLab•5/30/22, 9:17 PM

Just thinking out loud here... I noticed for pages functions in "advanced mode", you have to serve your static assets in your functions with

return env.ASSETS.fetch(request);

return env.ASSETS.fetch(request);

(see https://developers.cloudflare.com/pages/platform/functions/#advanced-mode). So at least in advanced mode it seems you could also proxy asset requests to another local development server (ie: create-react-app dev server running on port 3000). It would be a neat idea to add to wrangler2 to provide a local dev server url where you could both be debugging pages functions and running a framework dev server locally (that will later be compiled/transpiled to a bundled/minified production build before being published to pages). This I think describes the ask for people using React/Vue/Angular/etc.

Erwin•5/30/22, 11:26 PM

They are mostly the same. Pages Functions basically compile/bundle down to Workers. The current limitations mean that you can't configure the Pages Functions Worker as completely yet as you can a regular Worker. So you can't yet set any compatibility date/flags..

And you can't deploy any Durable Objects inside your Pages repository. (Although you can bind a DO published by another Worker)..

I'm assuming you mean on Functions. You can't currently use Prisma on Functions because it requires bundling with a bundler like WebPack or

If you mean Workers then that's totally possible. But I assumed you meant Functions because this is #functions

You can but it negates all of what Functions does, and the command for it is pretty undocumented.

(Advanced Mode +

Once a Response is read, you cannot read it again. If you transform oldResponse, you cannot return it

Of course. We will always support all the bindings Workers do. It's a little more complex so there is a delay but we will add it

my end goal is to read the html, find a specific tag with id "article", inject new element under it. When I read the html, it always says "undefined" for the innerHTML even when I use *.
