also, what is the widest possible class of this code that I can google so that I can find reusable code?

JS functions? Node.js functions? What should give me reusable code while also ensuring max possible userbase?

S

sumit•5/29/22, 3:50 PM

i feel really awkward asking everything on this channel even though y'all are really nice

GregBrimble•5/29/22, 3:51 PM

“Pure JS” for the general day-to-day is usually what I search for. Or “web API” if I’m needing something specific about how to access request/response sort of stuff.

The MDN docs are brilliant

Even some Node.JS stuff will work, as long as it doesn't import any node-js specific packages.

Ssumit so how would you have googled my previous question, for example?

I

Isaac McFadyenOP•5/29/22, 3:53 PM

I would have done "return object in javascript response"

oh cool

an Object is what the

{key: value}

{key: value}

{key: value}

{key: value} structure is called in JS.

sumit•5/29/22, 3:53 PM

cool

sumit•5/29/22, 4:00 PM

so if I want to get back my json on client side, what would you change in this code?

async function fetchProductsAsJSON() {
    const response = await fetch('https://mydomain.com/api/hello');
    // waits until the request completes...
    console.log(response);
  }

  fetchProductsAsJSON();

async function fetchProductsAsJSON() {
    const response = await fetch('https://mydomain.com/api/hello');
    // waits until the request completes...
    console.log(response);
  }

  fetchProductsAsJSON();

async function fetchProductsAsJSON() {
    const response = await fetch('https://mydomain.com/api/hello');
    // waits until the request completes...
    console.log(response);
  }

  fetchProductsAsJSON();

async function fetchProductsAsJSON() {
    const response = await fetch('https://mydomain.com/api/hello');
    // waits until the request completes...
    console.log(response);
  }

  fetchProductsAsJSON();

although in the context of code running in Workers or Functions, it's not 1:1 the fetch you'll see on MDN

K

kian•5/29/22, 4:06 PM

so there's https://developers.cloudflare.com/workers/runtime-apis/fetch/

Fetch · Cloudflare Workers docs

Documentation for Cloudflare Workers, a serverless execution environment that allows you to create entirely new applications or augment existing ones without configuring or maintaining infrastructure.

K

kian•5/29/22, 4:07 PM

it's like 90% the same but there's a few bits here and there that aren't in Workers

S

sumit•5/29/22, 4:07 PM

is there a porting guide?

K

kian•5/29/22, 4:07 PM

it's mostly a few things from the

init on here https://developer.mozilla.org/en-US/docs/Web/API/fetch

The global fetch() method starts the process of fetching a
resource from the network, returning a promise which is fulfilled once the response is
available.

there's no mode/credentials/etc on Workers

then how auth headers get sent?

same as any other header

i can access environment vars in functions code, right?

Yup, it'll be on

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

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

platform

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

platform.env

platform.env

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

Call

next() instead

James•5/29/22, 9:44 PM

context.next()

context.next()

context.next()

context.next() in your example

J

James•5/29/22, 9:44 PM

Or you can

const file = await next()

const file = await next()

const file = await next()

const file = await next() to get the response and then run an

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?

Are pages functions different than cloudflare workers? Ie: don't necessarily have feature parity (I'm new-ish to both)
