I'm using TypeScript with the default tsconfig that is from the docs, I also have another tsconfig for the SPA part. This means that things like

Response

Response will be different between the two, and any code placed outside of

It's been a while since i touched Remix, but i remember they believed middleware was an anti-pattern.

What I did to overcome this was put what I would consider "middleware" in utility functions. Then, in every loader, i would call those utility functions. That way, I was as DRY as possible.

Miyagi•2/7/24, 3:59 PM

Unsure of best practice, i call my middleware function in the root.tsx... So its always listening.
....

I haven't fully tried this method, but when i attempted... wrangler cli will load and recognize your rules by logging a message in the console on startup

/pages/functions/middleware/

also consider:

/pages/functions/routing/

(cloudflare dot com obviously....)

You can't use the functions directory if you're using next-on-pages. You should be using Next.js middleware and API route handlers.

Hey All, I am trying to understand how wrangler page functions deploy works with domain aliases. I have used wrangler to successfully update my page function so when I use the pages.dev link it is working with the correct function, but when I access with the domain alias, sometimes I get the old page function behaviour and sometimes I get the new behaviour. I have tried a cache clear by hostname and it didn't clear out the old page function. Any ideas why the old page function would continue to serve?

what if some transitive deps don't import from the

Then it'll depend drastically on what/how they import things. If they import stuff that's covered by

These fixtures are what wrangler uses for its own tests

P

Paolo•2/9/24, 11:39 PM

Those are cool! those tests seem to be doing a fetch and checking the response, but instead I just call onRequestGet/Post with a mocked Request (as in a handcrafted object pretending to be a Request). I'm not sure it's the best way, but it sidesteps the network stack and I can set up the database contents more easily

[Need Help With Functions Source Maps]
I want to generate source maps for server side (i.e.

I found that

wrangler pages functions build ./functions --sourcemap

wrangler pages functions build ./functions --sourcemap

wrangler pages functions build ./functions --sourcemap

wrangler pages functions build ./functions --sourcemap command generates two file

index.js

index.js

&

index.js.map

index.js.map

index.js.map

index.js.map which seems something what I need.
But inspection of

index.js

index.js

reveals that it doesn't compile only

./functions

./functions

./functions

./functions code, but also the contents of

./src

./src

./src

./src folder.
That is weird, because docs for the command say

Compile a folder of Cloudflare Pages Functions into a single Worker

Compile a folder of Cloudflare Pages Functions into a single Worker

Compile a folder of Cloudflare Pages Functions into a single Worker

Compile a folder of Cloudflare Pages Functions into a single Worker

Is there a way to compile the

./functions into a worker file + sourcemaps and upload the generated worker afterwards?

I dont use `request.clone()` or `response.clone()`
