Also means that if you have an SPA any sub route that gets directly accessed. aka domain.com/blog will get billed because it will go through env.ASSETS.fetchenv.ASSETS.fetch right?

oooo good question..

Silvan

Silvan•3/31/25, 9:02 PM

yea i had that issue. when i refreshed a sub route i got a 404 so i had to add

app.get('/*', (c) => {
    return c.env.ASSETS.fetch(c.req.raw);
});

app.get('/*', (c) => {
    return c.env.ASSETS.fetch(c.req.raw);
});

at the end of the main aka server.ts

in my (react) pages project, this folder will be use for the "backend" (receive request) where I can safely import my SecretsSecrets (using env).

question about logging: I have observability on and a head sampling set to 1 (verified in wrangler.jsonc and UI) but I am seeing very infrequent logging. With "live" on I don't seen any requests despite many logs that should be firing. The app in question is using Astro using Cloudflare Workers deploy/CI.

React: what kind of React is this? If it's a framework like Next.js you need to use the framework's version of Functions, you can't use the functions folder directly.

I've been using Cloudflare to set up a url-accessible web build of a game I contribute to (R2 Bucket for the game's files, connected to a Worker to serve it to users). Since I'm pretty inexperienced when it comes to web infrastructure, I want to check my work security-wise.
There are no sensitive files in our build, so we're not worried about reading, but we obviously don't want users to be able to modify the contents of our R2 Bucket. The worker is coded to return 403 (or 400) for any requests that aren't GETGET or HEADHEAD. As best I can tell, this should make it impossible for users to modify our files, unless they can somehow modify the code of the worker itself (I assume they can't). Is that correct, or is there something else I need to do to make sure our web build is secure?

Assuming that you never call any functions that write/delete from the bucket, it doesn’t matter what requests they send to your Worker

They could send all of the POSTs they want, and it wouldn’t do anything

When using the Browser Rendering API, has anyone encountered issues with transformed elements? I have some skewed elements on my website but they are not rendered, just an empty space. It's just a skewY(10deg) en the text is skewY(-deg), is that because it uses GPU or somethign? Can we tweak the API to force it?

Do i understand this right.

if i want to deploy a pure static page with worker assets i just need

    "binding": "ASSETS"
  }

  "assets": {
    "directory": "./dist",

and no main?

if I were to create say 3 pages projects:
my-app-dev=====\
my-app-stage========== single-project-repo. (dev branch, stage branch, main branch)
my-app-prod ===/

how could I handle indepedent variables for each with a single wrangler file? can I have global values for all and then manually set values for each using api ? or would api settings overwrite values set by wrangler ?

Nah bro I agree to disagree It took me 3 hours to debug this.
You have to put these variables into your config without this the import.meta.env wont see the Cloudflare injected variables and noone talks about this.
Without the config.ts there is nothing CF related in the import.meta.env https://38625370.trash-vars.pages.dev/
With the config.ts CF populates and injects the variables as should be by default https://2d4b43b9.trash-vars.pages.dev/

Isaac McFadyen

I

Isaac McFadyen•4/1/25, 4:14 PM

Yes I understand that, but that's because Vite only puts variables that start with the VITE_VITE_ prefix into import.meta.env, which is why that config change is required

Isaac McFadyen

I

Isaac McFadyen•4/1/25, 4:15 PM

CF_PAGES_COMMIT_SHACF_PAGES_COMMIT_SHA doesn't start with VITE_VITE_ and so Vite hides it because it assumes you don't want to expose it to client code

Lemon

L

Lemon•4/1/25, 4:16 PM

Yeah I get it, but it would be nice to put these comments/precautions in to the CF docs (https://developers.cloudflare.com/pages/framework-guides/deploy-a-vite3-project/)
Could you push stuff like this to the CF team?

A lot, but some aren't really public.

Vercel uses Workers for their edge runtime
Shopify uses Cloudflare, and presumably Workers but not publicly confirmed
civit.ai uses R2 and Workers for all file downloads
Nodecraft uses Workers for some of their APIs
And https://workers.cloudflare.com has logos of a bunch of companies (i.e. Discord, NPM, maxmind) but no details on how they actually use Workers.
