Hey guys, I am trying to build a function using cloudflare pages and hono.js

Although, when I go to

http://127.0.0.1:65193/api/hello

http://127.0.0.1:65193/api/hello

it just says 404 not found

Why is that? I have also attached my folder structure. Am I doing something wrong?

I am referencing these docs https://hono.dev/getting-started/cloudflare-pages

Cloudflare Pages - Hono

Ultrafast web framework for Cloudflare Workers, Fastly Compute@Edge, Deno, Bun, Vercel, Lagon, Node.js, and others. Fast, but not only fast.

hi

how can i redirect to a URL in

_middleware.ts

_middleware.ts

?
currently, it gives me the wonderful "unable to parse URL"

here is the code from the middleware, maybe someone can tell me what i am doing wrong.

if (cookieIsSet()) {
    context.next();
} else {
    return Response.redirect("/login", 302);
}

if (cookieIsSet()) {
    context.next();
} else {
    return Response.redirect("/login", 302);
}

if (cookieIsSet()) {
    context.next();
} else {
    return Response.redirect("/login", 302);
}

if (cookieIsSet()) {
    context.next();
} else {
    return Response.redirect("/login", 302);
}

You need to pass a full URL

ok... thanks
that's kinda impractical for my usecase though.
i think i'll just answer with 403s instead.
thanks anyway!

Hey, I am trying to send an email with a cloudlfare page function. I am following this tutorial https://developers.cloudflare.com/email-routing/email-workers/send-email-workers/ for the new email workers but im stuck -- it says to put something in a wrangler.toml file, but there is no wrangler.toml file in cf pages? where do i put it instead?

You can't use

send_email

send_email

bindings with Pages/Functions.

ok:(

Hey all, using SvelteKit in Cloudflare Pages/Functions, and running locally via

wrangler pages dev -e dev -- vite dev

wrangler pages dev -e dev -- vite dev

(proxy mode). Unfortunately it seems that a

Location

Location

header doesn't make it all the way back to my browser but instead wrangler/workerd/mf is following the redirect internally. Is there a way to enable this passthrough? I saw the attached note but not sure if that's the same thing. Strangely, it seems that other SvelteKit headers are passed through, i.e

X-Sveltekit-Page

X-Sveltekit-Page

, but Location isn't.

I added the `nodejs_compat` flag to the pages > functions > compatibility flags, but it doesnt work.
