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•8mo 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

GetPsyched•8mo 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•8mo ago

term environment variable not set issue still?

GetPsyched•8mo ago

yes the logs look identical to before adding the adapter

Brody•8mo ago

what is your start script

GetPsyched•8mo ago

the default? I didn't alter anything on Railway

Brody•8mo ago

what is it

GetPsyched•8mo ago

checking

GetPsyched•8mo ago

nothing?

Brody•8mo ago

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

GetPsyched•8mo ago

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

Brody•8mo ago

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

GetPsyched•8mo 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•8mo ago

just start the node server

GetPsyched•8mo ago

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

Brody•8mo ago

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

GetPsyched•8mo ago

Brody•8mo ago

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

GetPsyched•8mo ago

right so bun run build && node build

Brody•8mo ago

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

GetPsyched•8mo ago

OH oh yeah lol it's 2 am here sorry

Brody•8mo 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

GetPsyched•8mo ago

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

Brody•8mo ago

yes you do

GetPsyched•8mo ago

I simply have these

Brody•8mo ago

vite build makes one with the node adapter

GetPsyched•8mo ago

ah, build/index.js

Brody•8mo ago

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

GetPsyched•8mo 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•8mo ago

well what is prince

GetPsyched•8mo 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•8mo ago

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

GetPsyched•8mo 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•8mo ago

is it an overlay?

GetPsyched•8mo 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
  '';
}

GetPsyched•8mo ago

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

Brody•8mo ago

what's it named

GetPsyched•8mo ago

checking should be princexml

Brody•8mo ago

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

GetPsyched•8mo ago

yeah I can't find it either

Brody•8mo 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

GetPsyched•8mo ago

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

Brody•8mo ago

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

GetPsyched•8mo ago

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

Brody•8mo ago

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

GetPsyched•8mo 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•8mo ago

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

GetPsyched•8mo ago

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

Brody•8mo ago

that starts a dev server

GetPsyched•8mo ago

rip

Brody•8mo ago

use bun to run the index.js file

GetPsyched•8mo ago

because apparently there's a lot of pain happening

GetPsyched•8mo ago

I will just switch to nodejs

Brody•8mo ago

its for the better

GetPsyched•8mo 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•8mo ago

lets see the nixpacks.toml file

GetPsyched•8mo 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•8mo ago

you edited it

I don't see it on my screen do you

Brody•8mo ago

you just sent it again, so yes

GetPsyched•8mo ago

weird.

Brody•8mo ago

full logs please also whats with the runimage and cmd?

GetPsyched•8mo ago

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

Brody•8mo 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?

GetPsyched•8mo 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•8mo ago

run it in the same phase

GetPsyched•8mo ago

Okay, and the path would just be /bin?

Brody•8mo ago

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

GetPsyched•8mo 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•8mo ago

you dont need to, its just an example?

GetPsyched•8mo ago

I see

GetPsyched•8mo ago

weird.

GetPsyched•8mo 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'

[variables]
    pname = 'princexml'
    version = '15.1'
    full_name = 'prince-${version}-linux-generic-x86_64'

I had done this

Brody•8mo ago

no you cant

GetPsyched•8mo 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•8mo ago

did you put the binary in /bin ?

GetPsyched•8mo ago

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

GetPsyched•8mo ago

hehe it can choose

Brody•8mo ago

not how it works

GetPsyched•8mo ago

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

Brody•8mo ago

does it even need a path

GetPsyched•8mo ago

yes

Brody•8mo ago

it can decide itself

GetPsyched•8mo ago

base=$( dirname "$0" )

cd "$base" || exit 1

base=$( dirname "$0" )

cd "$base" || exit 1

this is a line inside install.sh

Brody•8mo ago

Press Enter to accept the default directory or enter an alternative

GetPsyched•8mo ago

wait then what is this

Brody•8mo ago

current dir

GetPsyched•8mo ago

I see

Brody•8mo ago

did you write this?

GetPsyched•8mo ago

yes a long while back

Brody•8mo ago

who wrote this then

GetPsyched•8mo ago

also me

Brody•8mo ago

🤨

GetPsyched•8mo 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•8mo ago

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

GetPsyched•8mo 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•8mo ago

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

GetPsyched•8mo ago

yes

GetPsyched•8mo ago

so it is in /usr/local thonk

the prefix so /usr/local/bin hmm

Brody•8mo ago

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

GetPsyched•8mo 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•8mo ago

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

GetPsyched•8mo ago

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

Brody•8mo ago

read their docs?

GetPsyched•8mo ago

they don't have docs IIRC

Brody•8mo ago

read the source code?

GetPsyched•8mo 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•8mo ago

but how do you run the download

GetPsyched•8mo 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•8mo ago

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

GetPsyched•8mo ago

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

Brody•8mo ago

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

GetPsyched•8mo ago

but it doesn't (╯°□°)╯︵ ┻━┻

Brody•8mo ago

sounds like something is misconfigured

GetPsyched•8mo ago

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

Brody•8mo ago

then specify /bin as the install path

GetPsyched•8mo 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
