sveltekit service crashing :(

I just deployed my brand new project on Railway and it tried running the bun run start command repeatedly which kept failing with the following error:

TERM environment variable not set.
error: script "start" exited with code 1 (SIGHUP)

TERM environment variable not set.
error: script "start" exited with code 1 (SIGHUP)

The service inevitably crashed.

Perhaps this is because I don't have any adapter setup?

Brody•14mo ago

definitely is, you would want to use the node adapter and hope it's compatible with bun, if it's not then you have to use nodejs

GetPsychedOP•14mo ago

Switching to nodejs shouldn't be a problem Will try adding the node adapter Tried adding the node adapter. The issue persists. I doubt this is because of bun since it works on my local machine cc @Brody

Brody•14mo ago

term environment variable not set issue still?

GetPsychedOP•14mo ago

yes the logs look identical to before adding the adapter

Brody•14mo ago

what is your start script

GetPsychedOP•14mo ago

the default? I didn't alter anything on Railway

Brody•14mo ago

what is it

GetPsychedOP•14mo ago

checking

GetPsychedOP•14mo ago

nothing?

Brody•14mo ago

not quite what I asked the start script.. in the package.json

GetPsychedOP•14mo ago

Ah! bun run css && vite build && clear && vite preview css being: bunx tailwindcss -i ./src/app.css -o ./dist/tailwind.css

Brody•14mo ago

that's not a start script or at least it shouldn't be yours

GetPsychedOP•14mo ago

  "scripts": {
    "css": "bunx tailwindcss -i ./src/app.css -o ./dist/tailwind.css",
    "dev": "bun run css && vite dev",
    "build": "bun run css && vite build",
    "preview": "bun run css && vite preview",
    "start": "bun run css && vite build && clear && vite preview"
  },

  "scripts": {
    "css": "bunx tailwindcss -i ./src/app.css -o ./dist/tailwind.css",
    "dev": "bun run css && vite dev",
    "build": "bun run css && vite build",
    "preview": "bun run css && vite preview",
    "start": "bun run css && vite build && clear && vite preview"
  },

what should it be then

Brody•14mo ago

just start the node server

GetPsychedOP•14mo ago

so bun run css && vite build && node build? ref: https://kit.svelte.dev/docs/adapter-node

Brody•14mo ago

haha I've seen the node adapter docs, have you lol

GetPsychedOP•14mo ago

Brody•14mo ago

you already run css and build in your build script, why are you running them again?

GetPsychedOP•14mo ago

right so bun run build && node build

Brody•14mo ago

you already run build in your build script, why are you running it again?

GetPsychedOP•14mo ago

OH oh yeah lol it's 2 am here sorry

Brody•14mo ago

and while node build might work, you should be more explicit and specify the full path to the JavaScript file that you want to run

GetPsychedOP•14mo ago

I don't have any specific JS file to run?

Brody•14mo ago

yes you do

GetPsychedOP•14mo ago

I simply have these

Brody•14mo ago

vite build makes one with the node adapter

GetPsychedOP•14mo ago

ah, build/index.js

Brody•14mo ago

have a read 😉 node build/index.js would use node to run the server, I thought you wanted to use bun?

GetPsychedOP•14mo ago

And you'd be right. I'm looking for a bun equivalent rn lol But yeah a more critical error would be: Error: Prince#execute: cannot resolve binary "prince" to a filesystem path 😔 headed to prince docs or wait is there a way to install prince to the project env in Railway? like I did with SQLC back then some TOML file

Brody•14mo ago

well what is prince

GetPsychedOP•14mo ago

it is a tool that compiles HTML -> PDF among some other things I've defined it in my flake.nix, but Railway doesn't refer that 😔 PrinceXML to be precise

Brody•14mo ago

is it available as a nix package or an apt package?

GetPsychedOP•14mo ago

nix package likely both oh wait it isn't available as a nix package I wrote my own package for it it's in the same project folder, is it possible for Railway to refer to that rather than nixpkgs?

Brody•14mo ago

is it an overlay?

GetPsychedOP•14mo ago

no, I just wrote my own package for it very tiny script:

{ autoPatchelfHook, fetchurl, fontconfig, glibc, stdenv }:

stdenv.mkDerivation rec {
  pname = "princexml";
  version = "15.1";
  src = fetchurl {
    url = "https://www.princexml.com/download/prince-${version}-linux-generic-x86_64.tar.gz";
    hash = "sha256-rm0GeKPa8iDXBhW52GNcja09Qb+aYUtvFaxZUFHEOTw=";
  };

  nativeBuildInputs = [ autoPatchelfHook ];

  buildInputs = [
    fontconfig
    glibc
  ];

  installPhase = ''
    ./install.sh $out
    ln -sf /var/lib/prince/license.dat $out/lib/prince/license/license.dat
  '';
}

{ autoPatchelfHook, fetchurl, fontconfig, glibc, stdenv }:

stdenv.mkDerivation rec {
  pname = "princexml";
  version = "15.1";
  src = fetchurl {
    url = "https://www.princexml.com/download/prince-${version}-linux-generic-x86_64.tar.gz";
    hash = "sha256-rm0GeKPa8iDXBhW52GNcja09Qb+aYUtvFaxZUFHEOTw=";
  };

  nativeBuildInputs = [ autoPatchelfHook ];

  buildInputs = [
    fontconfig
    glibc
  ];

  installPhase = ''
    ./install.sh $out
    ln -sf /var/lib/prince/license.dat $out/lib/prince/license/license.dat
  '';
}

GetPsychedOP•14mo ago

it is available on Ubuntu. I'm guessing that means it's on apt, by extension?

Brody•14mo ago

what's it named

GetPsychedOP•14mo ago

checking should be princexml

Brody•14mo ago

https://packages.ubuntu.com/search?keywords=princexml&searchon=names&suite=kinetic&section=all

GetPsychedOP•14mo ago

yeah I can't find it either

Brody•14mo ago

looks like you will have to install install prince the same sort of way i install caddy here https://github.com/brody192/vite-react-template/blob/main/nixpacks.toml

GetPsychedOP•14mo ago

On that note did the team say anything about flake support? would fix all my dependency issues

Brody•14mo ago

they want to support it natively, its just a low priority because few people use it

GetPsychedOP•14mo ago

:( I see Makes perfect sense from a business POV but still a bummer lol

Brody•14mo ago

but if you can write nix packages, writing a nixpacks.toml file would be no issue

GetPsychedOP•14mo ago

It's about understanding how the toml works either way, this script is extremely tiny, so you're right, it should be relatively simple

Brody•14mo ago

if you can understand how nix packages work, you can understand nixpacks.toml

GetPsychedOP•14mo ago

yes BTW, can I not use bun run preview as my start script? it expanding to bun run css && vite preview

Brody•14mo ago

that starts a dev server

GetPsychedOP•14mo ago

rip

Brody•14mo ago

use bun to run the index.js file

GetPsychedOP•14mo ago

because apparently there's a lot of pain happening

GetPsychedOP•14mo ago

I will just switch to nodejs

Brody•14mo ago

its for the better

GetPsychedOP•14mo ago

indeed invalid use of variables?

ERROR: failed to solve: process "/bin/bash -ol pipefail -c tar -zxvf ${pname}.tar.gz ${pname}" did not complete successfully: exit code: 2

Brody•14mo ago

lets see the nixpacks.toml file

GetPsychedOP•14mo ago

it likely won't work as it's the first draft just wanted to see what breaks huh I didn't delete it

Brody•14mo ago

you edited it

I don't see it on my screen do you

Brody•14mo ago

you just sent it again, so yes

GetPsychedOP•14mo ago

weird.

Brody•14mo ago

full logs please also whats with the runimage and cmd?

GetPsychedOP•14mo ago

Oh, there is no princexml subfolder in the tar.gz unsure. It's residue from caddy :P

Brody•14mo ago

delete the start phase also in your princexml phase you may want to copy the resulting binary file into maybe /bin or /usr/bin since your code prob expects it in path?

GetPsychedOP•14mo ago

yeah so there is ...tar.gz/foo/install.sh that I want to run (it does the binary stuff) where do I put it? [phases.install]?

Brody•14mo ago

run it in the same phase

GetPsychedOP•14mo ago

Okay, and the path would just be /bin?

Brody•14mo ago

no, the PATH would be a bunch of different locations https://utilities.up.railway.app/env-vars?prefix=PATH

GetPsychedOP•14mo ago

not the PATH for prince the PATH for the binary file wait that's the same thing ah so how do I refer to this env? or do I have to copy paste/

Brody•14mo ago

you dont need to, its just an example?

GetPsychedOP•14mo ago

I see

GetPsychedOP•14mo ago

weird.

GetPsychedOP•14mo ago

idt it threw a 404 before I copy pasted that URL, replacing ${version} and it works no problem wonder why Railway throws a 404 probably a substitution error Oh I can't reference variables in other variables?

[variables]
    pname = 'princexml'
    version = '15.1'

    version = '15.1'
    full_name = 'prince-${version}-linux-generic-x86_64'

I had done this

Brody•14mo ago

no you cant

GetPsychedOP•14mo ago

yeah realised now hmm so the build works but this error came back If the build failed, then I likely need to tell the lib where the binary is where is it? 💀

Brody•14mo ago

did you put the binary in /bin ?

bruh /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin?????

GetPsychedOP•14mo ago

hehe it can choose

Brody•14mo ago

not how it works

GetPsychedOP•14mo ago

that's valid bash, though okay okay, so I do this? './${full_name}/install.sh /bin'

Brody•14mo ago

does it even need a path

GetPsychedOP•14mo ago

yes

Brody•14mo ago

it can decide itself

GetPsychedOP•14mo ago

base=$( dirname "$0" )

cd "$base" || exit 1

base=$( dirname "$0" )

cd "$base" || exit 1

this is a line inside install.sh

Brody•14mo ago

Press Enter to accept the default directory or enter an alternative

GetPsychedOP•14mo ago

wait then what is this

Brody•14mo ago

current dir

GetPsychedOP•14mo ago

I see

Brody•14mo ago

did you write this?

GetPsychedOP•14mo ago

yes a long while back

Brody•14mo ago

who wrote this then

GetPsychedOP•14mo ago

also me

Brody•14mo ago

🤨

GetPsychedOP•14mo ago

what are you raising brows for It's 3 AM, I'm not usually this stupid okay now I didn't pass a path what's the "default" since I need to tell that to my application it still doesn't find the binary at whatever the default is

Brody•14mo ago

looks like /usr/local/bin and that should be in PATH

GetPsychedOP•14mo ago

there is an option in node-prince (the npm lib) for setting the binary but that might break local builds unless I remove it locally and keep it in prod

Brody•14mo ago

do you see the Installation complete. message in your build logs

GetPsychedOP•14mo ago

yes

GetPsychedOP•14mo ago

so it is in /usr/local thonk

the prefix so /usr/local/bin hmm

Brody•14mo ago

should be and that also should be in PATH, so the npm package should look in PATH automatically

GetPsychedOP•14mo ago

here's what the docs for the package say:

Prince#binary(binary): Prince: set the path to the prince(1) binary. By default it is prince (in case PrinceXML was found globally installed at the Node API installation time) or the path to the prince binary of the locally installed PrinceXML distribution (in case PrinceXML was not found globally installed at the Node API installation time). This returns the Prince API for further method chaining.

Prince#binary(binary): Prince: set the path to the prince(1) binary. By default it is prince (in case PrinceXML was found globally installed at the Node API installation time) or the path to the prince binary of the locally installed PrinceXML distribution (in case PrinceXML was not found globally installed at the Node API installation time). This returns the Prince API for further method chaining.

there is also:

Prince#prefix(prefix): Prince: set the path to the PrinceXML installation. This by default is either empty (in case PrinceXML was found globally installed at the Node API installation time) or the path to the locally installed PrinceXML distribution (in case PrinceXML was not found globally installed at the Node API installation time). This returns the Prince API for further method chaining.

Prince#prefix(prefix): Prince: set the path to the PrinceXML installation. This by default is either empty (in case PrinceXML was found globally installed at the Node API installation time) or the path to the locally installed PrinceXML distribution (in case PrinceXML was not found globally installed at the Node API installation time). This returns the Prince API for further method chaining.

ref: https://www.npmjs.com/package/prince

Brody•14mo ago

it can download prince for you? why havent you used that?

GetPsychedOP•14mo ago

there is nothing to use? it doesn't specify anything I'm supposed to do to install prince automatically

Brody•14mo ago

read their docs?

GetPsychedOP•14mo ago

they don't have docs IIRC

Brody•14mo ago

read the source code?

GetPsychedOP•14mo ago

this readme is all they have lol ok Should be this https://github.com/rse/node-prince/blob/master/prince-npm.js#L292-L300

Brody•14mo ago

but how do you run the download

GetPsychedOP•14mo ago

as it says here:

in case PrinceXML was not found globally installed at the Node API installation time

so likely the download is automatically done at "Node API installation time"? I found nothing regarding this in my build logs

Brody•14mo ago

so then are you trying to overwrite the location in your code?

GetPsychedOP•14mo ago

yes, to wherever it was installed using ./install.sh

Brody•14mo ago

the package should find it automatically since it installs it into a folder in PATH

GetPsychedOP•14mo ago

but it doesn't (╯°□°)╯︵ ┻━┻

Brody•14mo ago

sounds like something is misconfigured

GetPsychedOP•14mo ago

the error originates from here: https://github.com/rse/node-prince/blob/master/prince-api.js#L281-L293

Brody•14mo ago

then specify /bin as the install path

GetPsychedOP•14mo ago

why so? I wasn't asking why should I specify /bin in the install path I was asking why /bin specifically This is an issue upstream. It can't detect NixOS as a Linux distribution Being punished for being curious oof
