How can I execute shell commands in Svelte?

GetPsychedOP•10/4/23, 5:55 PM

using child-processchild-process doesn't work since it uses Node and CF doesn't support that

There's a good overview here, might clear up some of your confusion around why Workers doesn't have a shell or indeed any execution environment other than JavaScript: https://developers.cloudflare.com/workers/learning/how-workers-works/

Hey all. I have just setup a Domain a few hours ago (around 20ish) i have added the domain to github pages. When i do access the site i get met with this error message:

You might be better off in No Access, this channel is about Cloudflare pages not Github pages.

Deleted User•10/4/23, 6:06 PM

Ah, Just because CloudFlare was who i got the domain from

No worries

i’ve noticed that when i create a new pages project, it takes a couple minutes for the .pages.dev domain to become “active”. does anyone know why this might be? i was hoping it would be instantaneous, since it’s just a subdomain

This is because it provisions a certificate for every new Pages project.

Avi•10/4/23, 6:19 PM

ah i see! is there anything I can do to speed up that time? or any sense of how long that process could take on average/worst case?

Avi•10/4/23, 6:20 PM

we're provisioning a new pages project on each deploy of our codebase (so we can support parallel deployments in prod for the last few versions)

Isaac McFadyen•10/4/23, 6:22 PM

Hmm... I don't think there's anything that can be done to speed it up unfortunately, it just takes as long as it takes normally.

we need to make sure our backend and frontend versions match, so we deploy a new worker (DO) and frontend (pages instance) each time, and ensure we route folks to the right version

.. my mistake, but maybe it's not mine ... on the first deploy I used "#!/bin/sh curl -sSL https://dot.net/v1/dotnet-install.sh > dotnet-install.sh chmod +x dotnet-install.sh ./dotnet-install.sh -c 7.0 -InstallDir ./dotnet ./dotnet/dotnet --version ./dotnet/dotnet publish -c Release -o output" and Build output directory: /wwwroot because that was the only way it wanted to go through ... later I changed to Build output directory: /output/wwwroot and the aforementioned mistake remained. However, now I have a situation where whatever I do everything looks normal but it's like it's pulling an old page from some cache and after a new deployment, we still have the old page.

Avi•10/5/23, 4:13 AM

you need to make a "pages function" to do that, and then call that function from the cloudflare page, e.g. some javascript running on your page. the function is essentially just a regular cloudflare worker that happens to be "inside" your pages project

Thanks for the pointer. But where is the part that calls

export async function onRequest(context)

and uses the value? Does is always act like a middleware? Would I need to route this manually like in https://developers.cloudflare.com/pages/platform/functions/examples/ab-testing/ ?

Avi•10/5/23, 4:02 PM

that’s called automatically whenever a request comes in, as the name suggests. it’s a bit magical but it’s not really any different than how regular workers work

Rich•10/5/23, 4:05 PM

For anybody else that's interested, after some further investigation, I can confirm that these docs are incorrect. If you deploy

_routes.json

_routes.json

, even when using advanced mode (

_worker.js

_worker.js

), you do not need to serve static assets using

env.ASSETS.fetch

env.ASSETS.fetch

-- it's done for you.

tcurdt•10/5/23, 4:53 PM

Yeah, that's clear. It acts like a middleware. But I am confused whether every function needs to act as middleware.

Which means that a possible routing has to happen inside the functions as well. Not all requests of the whole site necessarily have to be piped through that request handler. Let's say you have a site that just wants to make a certain db query on a certain page. Example:

export async function onRequest({ request, next, env }) {
  const url = new URL(request.url)
  if (url.pathname === "/foo") {
    return new Response("foo")
  }
  if (url.pathname === "/far") {
    return new Response("bar")
  }
  return next()
}

export async function onRequest({ request, next, env }) {
  const url = new URL(request.url)
  if (url.pathname === "/foo") {
    return new Response("foo")
  }
  if (url.pathname === "/far") {
    return new Response("bar")
  }
  return next()
}

kian•10/5/23, 5:00 PM

All of the

onRequest

onRequest

syntax is specific to Functions file-based routing, so whilst you could have a middleware that does routing based on the request URL, you'd rather do

functions/foo.ts

functions/foo.ts

and

functions/bar.ts

functions/bar.ts

kian•10/5/23, 5:01 PM

next()

next()

just falls through to the asset server if it isn't a middleware.

Elliot Hesp•10/6/23, 3:23 PM

Hey all,

If my pages functions threw an error, how am I supposed to view what the error was?

Pages doesn't support log push, so unless I leave it streaming logs they seemingly go into the void? My application didn't even recieve the request (or it broke somewhere before it gets to my logging) so really confused as to what the issue is

Elliot Hesp•10/6/23, 3:24 PM

It's almost as if Pages itself had an issue, since everything is seemingly back to normal :/

Elliot Hesp•10/6/23, 3:26 PM

I've also had customers reporting API endpoints which should return JSON returned HTML (assuming a cloudflare error page)

export async function onRequest({ request, next, env }) { const url = new URL(request.url) if (url.pathname === "/foo") { return new Response("foo") } if (url.pathname === "/far") { return new Response("bar") } return next() }

How can I execute shell commands in Svelte?
