Repro steps
Follow example here: https://developers.cloudflare.com/pages/framework-guides/deploy-a-remix-site/

npm create cloudflare@latest my-remix-app -- --framework=remix
cd my-remix-app
npm run dev

Which results in the following logs

$ npm run dev

> dev
> remix dev --manual -c "npm run start"

I've tried downgrading wrangler to v3.8.0, and to 3.1.1

Remix is a framework that is focused on fully utilizing the power of the web. Like Cloudflare Workers, it uses modern JavaScript APIs, and it places …

I'm able to repro with npm start as well. It looks like miniflare is not happy about something in the public/build directory

Have you tried to init the project with the remix cli instead of cloudflare? https://remix.run/docs/en/main/other-api/create-remix

Remix

create-remix (CLI)

#

npx create-remix --template remix-run/remix/templates/cloudflare-pages

#

I‘ve also had issues with wrangler 3.9 so I keep it at 3.8 for now (it started but crashed after some code changes)

open quail Sep 23, 2023, 3:56 PM

#

trying now

#

Hmm still the same issues (even with bumping down to 3.8 and rerunning npm install)

jovial sequoia Sep 23, 2023, 4:00 PM

#

Ah, maybe a shot into the blue, but could there be another wrangler instance running on your machine?

#

Sometimes I got start up issues when I have another project running

#

You could also try increasing the compatibility date of the wrangler env. Just put the current date there (check in package.json)

ok will try that next

#

no luck 😢

jovial sequoia Sep 23, 2023, 4:05 PM

#

very strange. I'll pull your repo and try on my machine

#

that's odd, it works for me :/

#

what's your node and npm version?

#

I'm on node 18.17.1, so maybe this

Here's the shape of my public folder after running npm run build

jovial sequoia Sep 23, 2023, 4:07 PM

#

public looks good

open quail Sep 23, 2023, 4:07 PM

#

I'm on node v20.6.1 will bump down to 18.17.1, zap node_modules and try again

#

No luck with node v18.17.1

jovial sequoia Sep 23, 2023, 4:08 PM

#

wow that's frustrating...

open quail Sep 23, 2023, 4:08 PM

#

I think the next step for me is to verify that wrangler pages works

#

and work up from there

jovial sequoia Sep 23, 2023, 4:08 PM

#

yeah that would be a good next test. also maybe plain worker

#

I'm on a 14" M2 mac. Wondering if there's an arm64 bug or something

jovial sequoia Sep 23, 2023, 4:09 PM

#

I'm on a M1

#

I remember that I sometimes also had some very strange issues. Like I said, another instance running for example. Also there was one case where I had to clean the project before running (rm -rf .cache functions public) or one occasion where I even had to restart the computer

open quail Sep 23, 2023, 4:11 PM

#

ooof yeah I'd hate for it to be at that level but everything's on the table at this point

jovial sequoia Sep 23, 2023, 4:12 PM

#

let's see what raw pages and worker will bring. Other than these issues sometimes, cloudflare environment with remix is really nice

open quail Sep 23, 2023, 4:15 PM

#

jfc 🤦‍♂️

#

ok I restarted the computer and its just working

#

@jovial sequoia thank you for talking through this with me 🎉

The other issue I had was that npm run dev didn't like that I was using crypto

diff --git a/remix.config.js b/remix.config.js
index e35ffad..f0ba820 100644
--- a/remix.config.js
+++ b/remix.config.js

   // assetsBuildDirectory: "public/build",
   // publicPath: "/build/",

This patched that issue, but I probably need to update that for deploying

Happy that I could help! 😃

ah btw regarding crypto, you may consider web crypto instead https://developer.mozilla.org/en-US/docs/Web/API/Web_Crypto_API

Web Crypto API - Web APIs | MDN

The Web Crypto API is an interface allowing a script to use cryptographic primitives in order to build systems using cryptography.
