Proxy URI path to external IP

I've recently tried deploying a NextJS site, and with the URL Rewrites not working I need to find an alternative.
I'm trying to route

/api/:path

/api/:path

/api/:path

/api/:path to an external IP where my API is hosted, but with very little luck.
The only thing that has worked so far is setting up a Page Redirect, but I don't want my API's IP address being exposed, and preferably proxied. Any straightforward way to do this?

You could try using middleware or next.config.js rewrites perhaps

I did try next.config.js rewrites, but they didn't work. thats why im trying to find an alternative

EthernalOP•7/22/23, 6:06 PM

And didn't work as in it has the same issues as the Page redirect, which is exposing the origin IP

EthernalOP•7/22/23, 6:08 PM

only thing I can really think of at the moment is to setup an api.domain/*api.domain/* instead of domain/api/*domain/api/*

EEthernal I did try next.config.js rewrites, but they didn't work. thats why im trying to ...

Are you using @cloudflare/next-on-pages@cloudflare/next-on-pages?

EthernalOP•7/22/23, 6:31 PM

Yes

EthernalOP•7/22/23, 6:34 PM

When going to <page>.pages.dev/api/:path<page>.pages.dev/api/:path it redirects me to the actual IP address instead of staying on <page>.pages.dev/api/:path<page>.pages.dev/api/:path, and im trying to avoid that

James•7/22/23, 7:15 PM

Ah... That's a bug then. Sorry about that - I'll look into a fix

EthernalOP•7/22/23, 7:19 PM

Oh, alright. thank you

James•7/22/23, 7:50 PM

Hey there, sorry again - this was my mistake a couple months back

James•7/22/23, 7:50 PM

I've opened a PR, I would welcome you to try out the prerelease in https://github.com/cloudflare/next-on-pages/pull/394#issuecomment-1646659126

EthernalOP•7/22/23, 7:51 PM

Ok, I'll go ahead and try that. thank you!

EthernalOP•7/22/23, 7:58 PM

Hm, it's still redirecting me

James•7/22/23, 8:02 PM

Can you please confirm that you're using the prerelease in that PR. It will say the version at the start of the next-on-pages build.

EthernalOP•7/22/23, 8:04 PM

I followed in installation guide on the PR, and my package.json reports

"@cloudflare/next-on-pages": "https://prerelease-registry.devprod.cloudflare.dev/next-on-pages/runs/5632432242/npm-package-next-on-pages-394",

"@cloudflare/next-on-pages": "https://prerelease-registry.devprod.cloudflare.dev/next-on-pages/runs/5632432242/npm-package-next-on-pages-394",

and then I pushed it to git and cloudflare redeployed the site

James•7/22/23, 8:05 PM

If your build command in the pages project settings is

npx @cloudflare/next-on-pages@1

npx @cloudflare/next-on-pages@1

with the @1@1 part, I think it will ignore the prerelease version, so could you just check that

EthernalOP•7/22/23, 8:07 PM

Ah- I had missed that part in the documentation, My build command is still next buildnext build FacePalm

James•7/22/23, 8:10 PM

Your package.json build script should be next buildnext build, and the default build command in the pages project settings on the dashboard is

npx @cloudflare/next-on-pages@1

npx @cloudflare/next-on-pages@1

when creating a new non-static Next.js pages project

EthernalOP•7/22/23, 8:11 PM

Oh, ok, so im extra dumb, lol. So remove the @1 from the from the build command?

James•7/22/23, 8:12 PM

Yeah if you remove the @1@1, it should build with the prerelease version instead

EthernalOP•7/22/23, 8:12 PM

Got it, removed the @1 and reverted to next buildnext build. redeploying now

EthernalOP•7/22/23, 8:16 PM

Kind of works, but now im getting a 1003, Direct IP access not allowed.

James•7/22/23, 8:20 PM

That'll be unrelated to anything in next-on-pages, and is instead because Cloudflare doesn't allow direct ip access to IPs in its network

Chaika•7/22/23, 8:22 PM

you can't fetch IPs from Workers/Functions, only domains

Chaika•7/22/23, 8:23 PM

ex. You could set up a proxied subdomain and fetch that from your function

EthernalOP•7/22/23, 8:24 PM

so setup my API on api.domainapi.domain and then proxy

/api

/api

-> api.domainapi.domain

James•7/22/23, 9:15 PM

Yeah give that a go
