create react app?

Not sure I understand the question sorry. Yes, the front end is React

was it made with create react app?

or react scripts, however you wanna call it

Ahhh, I beleve so. It's been a while since I initialized it.

Probably something like

npx create-react-app my-app --template typescript

does the api endpoint have to live on the same domain as the frontend?

No, but it's preferred.

I can do something like api.my_domain.com if I have to, but I'd prefer my_domain.com/api

okay fair enough

okay so let's get started

show me a screenshot of your railway project so I know what we are working with

Just this?

yep that's it

can I see a screenshot of the frontend project in github?

just the files and stuff

looking good

I'm gathering information so I can work out the best course of action

does the client have a public domain?

You mean like here? Not yet, but I do have a domain I will use

generate one, just for testing

client-staging-13a0.up.railway.app

delete the Dockerfile and nginx.conf from your repo.

copy the nixpacks.toml and Caddyfile from this repo into yours.

if you have any custom build or start commands set in the clients service settings, please remove them.

after that, let me know the outcome

if that works the next step will be to join the frontend and backend under one domain, but one step at a time

Build failed

ERROR: failed to solve: process "/bin/bash -ol pipefail -c npm run build" did not complete successfully: exit code: 1
Error: Docker build failed

I'm assuming it's because there's a few warnings that I have not cleaned up yet.

#19 77.49 Treating warnings as errors because [process.env.CI](process.env.CI) = true.

I'm new to Caddyfile, is there somewhere I can update this so it ignores warnings for now?

Caddyfile has nothing to do with building your site.

set a service variable CI to false

Ahhh okay, will let that build.

side note, please use this for sending me your build logs

the log snippet you sent didn't have any useful information.

Okay, looks like the build worked and the app is live via the url I sent above.

awesome, send another screenshot of the project please

do you have a PORT service variable set on the server service?

do you have a PORT service variable set on the server service?

In railway? no

can you show me the server code that starts listening?

what is the server domain set to

Just the domain I want to use for the application

please show me

Show you how?

I have an env variable set up in railway that it picks up.

screenshot please

show me the value

on second thought, please use this code instead of what you currently have, that way we know it's correct

func main() {
  // ...
  // Use `PORT` provided in environment or default to 3001
  var port = envPortOr("3001")

  log.Fatal(http.ListenAndServe(port, handler))
  // ...
}

// Returns PORT from environment if found, defaults to
// value in `port` parameter otherwise. The returned port
// is prefixed with a `:`, e.g. `":3001"`.
func envPortOr(port string) string {
  // If `PORT` variable in environment exists, return it
  if envPort := os.Getenv("PORT"); envPort != "" {
    return ":" + envPort
  }
  // Otherwise, return the value of `port` variable from function argument
  return ":" + port
}

I'm not going to need a domain on that?

nope

a domain isn't applicable here, and if you say it worked on railway I will be shocked

but then again, for some reason, you never did tell me what you had it set to

I had it set to my domain (with no port).

again, that's not telling me what it's set to

I don't understand the secrecy, but either way, please use the code I provided instead

Just not a domain I wanted to share. I'm not sure why knowing the exact domain matters. Could be my_domain.com and it wouldn't really make a difference.

Updated the code. Waiting for it to build

I understand that but details matter when dealing with these things, omitting details has dramatically increased the time it takes to resolve this and other help threads

Okay, server built and is active.

does it work?

Do you mean does the client call it? No

no, just the backend, does it work on its own?

Yes

https://sever-staging.up.railway.app/ping

on the client service, set a PORT service variable to 3000
on the server service, set a PORT service variable to 3001

Okay that's done

go ahead and deploy the reverse proxy template into your project.

for the FRONTEND_HOST variable, use http://${{Client.RAILWAY_PRIVATE_DOMAIN}}:${{Client.PORT}}

for the BACKEND_HOST variable, use http://${{Server.RAILWAY_PRIVATE_DOMAIN}}:${{Server.PORT}}

Deploying

What does the ENABLE_ALPINE_PRIVATE_NETWORKING env variable do? I'm not seeing it referenced in the reverse proxy code

there was a hyperlink under it that linked to docs explaining what it does

but for the end user, you can ignore it

so now you can remove the public domains from the server and client services because they will no longer be accessed publicly. you now use the domain on the proxy service

So I would just add my custom domain to the proxy service then? Instead of the client?

correct

Is this generally the expected deploy time for the proxy?

not at all

did you missconfigure something?

Let me double check

I noticed I was missing the http:// on the env variables. I added that, but it seems the health check is still failing on the server

full screenshot of your project please

why is the health check failing

1217519353122263152
1217519354111987802

you might need to make changes to the Caddyfile, please have a read of the comments in the Caddyfile

This is the correct health check plan? It was what it was set to when I created the template.

your backend does have an /api/ path right?

No, just figured this out. I updated it to /api/ping. That fixed it.

sorry but that's not the correct path you want to use

okay now that's good

so we in business?

We are good!

Thank you so much for your help! Greatly appriciated!

happy to help!
