try to use the full path

R

Ruxorly•4/2/24, 2:12 PM

so in your fetch do “http://127.0.0.1:8787/hello” as the url

R

Ruxorly•4/2/24, 2:12 PM

obviously in a production app you’d change that tho

Ruxorly•4/2/24, 2:23 PM

although i’m not well versed in remix, they could have a check to see if it’s a valid full url

R

Ruxorly•4/2/24, 2:24 PM

you might be able to use an environment variable to see if it’s running on prod and if it is, use that base url, otherwise use 127.0.0.1

V

vimoOP•4/2/24, 2:30 PM

You are not wrong to assume that but relative urls in Remix works.
Yes, I guess for now I will use a local env to concatenate it with the cf pages endpoint in my fetch calls. Will figure it out later when deploying if theres a better way or just if local concatenate else relative.
I hope relative url on deployment works.
Thanks for the help and env suggestion. Really appreciate it.

V

vimoOP•4/3/24, 9:27 AM

Are pages functions by default CORS protected? Since the function route works like an endpoint, do I have to worry about CORS protection?
Edit: Ah I see https://developers.cloudflare.com/pages/functions/examples/cors-headers/

Hey there!

Using Cloudflare pages functions, local building works great.

Everything compile with

wrangler pages dev  dist/

wrangler pages dev dist/

wrangler pages dev  dist/

wrangler pages dev dist/. Same using

wrangler pages functions build

wrangler pages functions build

wrangler pages functions build

wrangler pages functions build. This last says

Compiled Worker successfully.

If I compile locally and deploy with the next command, again the app is compiled and deployed with success :

wrangler pages deploy  dist/ --project-name my-project

wrangler pages deploy dist/ --project-name my-project

wrangler pages deploy  dist/ --project-name my-project

wrangler pages deploy dist/ --project-name my-project.

However, if a page build is triggered on Cloudflare based on git push, then the build fails with errors like the following:

Isaac McFadyen•4/4/24, 12:50 PM

I don't believe you can, and I don't think it will be coming. Pages relies on bundling your Functions into one big Worker at deploy time, which wouldn't really work with some being Python and some not - plus they inject custom code which is written in JS, which also wouldn't really work.

I

IEatBeans•4/8/24, 2:57 AM

I see that pages now supports a wrangler.toml. This is great, but what happens if you already have one for workers in the same project? I am using pages functions primarily, but workers for a few cron tasks. Do I need to move all the workers stuff into a subrepo, or can they both share a toml file?

Flare•4/9/24, 12:07 AM

Seeing a 401 error in your console during a Turnstile security check?
You can safely ignore the error, it's requesting a PAT but your device/browser does not support PATs yet, so you see the error.

How do you read your environment variables from wrangler.toml in Cloudflare Functions?

When I run in the function I get:

const publishableKey = env.STRIPE_PUBLISHABLE_KEY

const publishableKey = env.STRIPE_PUBLISHABLE_KEY

const publishableKey = env.STRIPE_PUBLISHABLE_KEY

const publishableKey = env.STRIPE_PUBLISHABLE_KEY

I get:

[wrangler:err] TypeError: Cannot read properties of undefined (reading 'STRIPE_PUBLISHABLE_KEY')

[wrangler:err] TypeError: Cannot read properties of undefined (reading 'STRIPE_PUBLISHABLE_KEY')

[wrangler:err] TypeError: Cannot read properties of undefined (reading 'STRIPE_PUBLISHABLE_KEY')

[wrangler:err] TypeError: Cannot read properties of undefined (reading 'STRIPE_PUBLISHABLE_KEY')

The function format is as following:

export async function onRequestGet(res, env, ctx) {  
// Code
}

export async function onRequestGet(res, env, ctx) {  
// Code
}

export async function onRequestGet(res, env, ctx) {

But I still don't get it, the post equivalent does not work when i do the same:

addEventListener('fetch', event => {
    event.respondWith(onRequestPost(event.request, event.env))
})
export async function onRequestGet(req,env) {  
  const requestBody = await req.json();
  const key = env.STRIPE_SECRET_KEY;
  // other code
}

addEventListener('fetch', event => {
    event.respondWith(onRequestPost(event.request, event.env))
})
export async function onRequestGet(req,env) {  
  const requestBody = await req.json();
  const key = env.STRIPE_SECRET_KEY;
  // other code
}

addEventListener('fetch', event => {
    event.respondWith(onRequestPost(event.request, event.env))
})
export async function onRequestGet(req,env) {  
  const requestBody = await req.json();
  const key = env.STRIPE_SECRET_KEY;
  // other code
}

addEventListener('fetch', event => {
    event.respondWith(onRequestPost(event.request, event.env))
})
export async function onRequestGet(req,env) {  
  const requestBody = await req.json();
  const key = env.STRIPE_SECRET_KEY;
  // other code
}

Or:

addEventListener('fetch', event => {
    event.respondWith(onRequestPost(event))
})
export async function onRequestGet(event) {  
  const { request, env } = event;
  const requestBody = await request.json();
  const key = env.STRIPE_SECRET_KEY;
  // other code
}

addEventListener('fetch', event => {
    event.respondWith(onRequestPost(event))
})
export async function onRequestGet(event) {  
  const { request, env } = event;
  const requestBody = await request.json();
  const key = env.STRIPE_SECRET_KEY;
  // other code
}

addEventListener('fetch', event => {
    event.respondWith(onRequestPost(event))
})
export async function onRequestGet(event) {  
  const { request, env } = event;
  const requestBody = await request.json();
  const key = env.STRIPE_SECRET_KEY;
  // other code
}

addEventListener('fetch', event => {
    event.respondWith(onRequestPost(event))
})
export async function onRequestGet(event) {  
  const { request, env } = event;
  const requestBody = await request.json();
  const key = env.STRIPE_SECRET_KEY;

both of these will give a error.
