sveltekit service crashing :( | Railway | Page 1

umbral mango Oct 8, 2023, 5:38 PM

#

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)

The service inevitably crashed.

umbral mango Oct 8, 2023, 6:07 PM

#

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

civic locust Oct 8, 2023, 6:19 PM

#

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

umbral mango Oct 8, 2023, 6:40 PM

#

Switching to nodejs shouldn't be a problem

#

Will try adding the node adapter

umbral mango Oct 8, 2023, 7:43 PM

#

Tried adding the node adapter. The issue persists.

#

I doubt this is because of bun since it works on my local machine

#

cc @civic locust

civic locust Oct 8, 2023, 7:46 PM

#

term environment variable not set issue still?

umbral mango Oct 8, 2023, 7:46 PM

#

yes

#

the logs look identical to before adding the adapter

civic locust Oct 8, 2023, 7:46 PM

#

what is your start script

umbral mango Oct 8, 2023, 7:47 PM

#

the default? I didn't alter anything on Railway

civic locust Oct 8, 2023, 7:47 PM

#

what is it

umbral mango Oct 8, 2023, 7:47 PM

#

checking

umbral mango Oct 8, 2023, 7:47 PM

#

civic locust what is it

nothing?

civic locust Oct 8, 2023, 7:48 PM

#

not quite what I asked

#

the start script.. in the package.json

umbral mango Oct 8, 2023, 7:48 PM

#

Ah!

#

bun run css && vite build && clear && vite preview

#

css being: bunx tailwindcss -i ./src/app.css -o ./dist/tailwind.css

civic locust Oct 8, 2023, 7:49 PM

#

that's not a start script

#

or at least it shouldn't be yours

umbral mango Oct 8, 2023, 7:49 PM

#

  "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

civic locust Oct 8, 2023, 7:50 PM

#

just start the node server

umbral mango Oct 8, 2023, 7:51 PM

#

civic locust just start the node server

so bun run css && vite build && node build?

#

ref: https://kit.svelte.dev/docs/adapter-node

civic locust Oct 8, 2023, 7:52 PM

#

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

umbral mango Oct 8, 2023, 7:52 PM

#

:(

civic locust Oct 8, 2023, 7:53 PM

#

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

umbral mango Oct 8, 2023, 7:53 PM

#

right so bun run build && node build

civic locust Oct 8, 2023, 7:53 PM

#

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

umbral mango Oct 8, 2023, 7:54 PM

#

OH

#

oh yeah

#

lol

#

it's 2 am here sorry

civic locust Oct 8, 2023, 7:55 PM

#

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

umbral mango Oct 8, 2023, 7:55 PM

#

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

civic locust Oct 8, 2023, 7:55 PM

#

yes you do

umbral mango Oct 8, 2023, 7:55 PM

#

I simply have these

civic locust Oct 8, 2023, 7:56 PM

#

vite build makes one with the node adapter

umbral mango Oct 8, 2023, 7:56 PM

#

ah, build/index.js

civic locust Oct 8, 2023, 7:56 PM

#

umbral mango ref: <https://kit.svelte.dev/docs/adapter-node>

have a read 😉

#

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

umbral mango Oct 8, 2023, 8:06 PM

#

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

civic locust Oct 8, 2023, 8:07 PM

#

well what is prince

umbral mango Oct 8, 2023, 8:08 PM

#

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

civic locust Oct 8, 2023, 8:08 PM

#

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

umbral mango Oct 8, 2023, 8:09 PM

#

nix package

#

likely both

#

oh wait it isn't available as a nix package

#

I wrote my own package for it

umbral mango Oct 8, 2023, 8:10 PM

#

umbral mango 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?

civic locust Oct 8, 2023, 8:11 PM

#

is it an overlay?

umbral mango Oct 8, 2023, 8:11 PM

#

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
  '';
}

umbral mango Oct 8, 2023, 8:12 PM

#

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

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

civic locust Oct 8, 2023, 8:12 PM

#

what's it named

umbral mango Oct 8, 2023, 8:13 PM

#

checking

#

should be princexml

civic locust Oct 8, 2023, 8:13 PM

#

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

umbral mango Oct 8, 2023, 8:14 PM

#

yeah I can't find it either

civic locust Oct 8, 2023, 8:15 PM

#

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

umbral mango Oct 8, 2023, 8:15 PM

#

On that note

#

did the team say anything about flake support?

#

would fix all my dependency issues

civic locust Oct 8, 2023, 8:16 PM

#

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

umbral mango Oct 8, 2023, 8:16 PM

#

:(

#

I see

#

Makes perfect sense from a business POV but still a bummer lol

civic locust Oct 8, 2023, 8:17 PM

#

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

umbral mango Oct 8, 2023, 8:17 PM

#

It's about understanding how the toml works

umbral mango Oct 8, 2023, 8:18 PM

#

umbral mango very tiny script: ```nix { autoPatchelfHook, fetchurl, fontconfig, glibc, stdenv...

either way, this script is extremely tiny, so you're right, it should be relatively simple

civic locust Oct 8, 2023, 8:18 PM

#

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

umbral mango Oct 8, 2023, 8:20 PM

#

yes

#

BTW, can I not use bun run preview as my start script?

#

it expanding to bun run css && vite preview

civic locust Oct 8, 2023, 8:28 PM

#

that starts a dev server

umbral mango Oct 8, 2023, 8:28 PM

#

rip

civic locust Oct 8, 2023, 8:28 PM

#

use bun to run the index.js file

umbral mango Oct 8, 2023, 8:28 PM

#

because apparently there's a lot of pain happening

#

I will just switch to nodejs

civic locust Oct 8, 2023, 8:30 PM

#

its for the better

umbral mango Oct 8, 2023, 8:31 PM

#

indeed

umbral mango Oct 8, 2023, 8:54 PM

#

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

civic locust Oct 8, 2023, 8:54 PM

#

lets see the nixpacks.toml file

umbral mango Oct 8, 2023, 8:55 PM

#

it likely won't work as it's the first draft

#

just wanted to see what breaks

#

huh

#

I didn't delete it

civic locust Oct 8, 2023, 8:56 PM

#

you edited it

umbral mango Oct 8, 2023, 8:56 PM

full logs please

#

also whats with the runimage and cmd?

umbral mango Oct 8, 2023, 8:59 PM

#

Oh, there is no princexml subfolder in the tar.gz

umbral mango Oct 8, 2023, 8:59 PM

#

civic locust also whats with the runimage and cmd?

unsure. It's residue from caddy :P

civic locust Oct 8, 2023, 9:01 PM

#

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?

umbral mango Oct 8, 2023, 9:02 PM

#

yeah so

umbral mango Oct 8, 2023, 9:02 PM

#

civic locust also in your princexml phase you may want to copy the resulting binary file into...

there is ...tar.gz/foo/install.sh that I want to run (it does the binary stuff)

#

where do I put it?

#

[phases.install]?

civic locust Oct 8, 2023, 9:03 PM

#

run it in the same phase

umbral mango Oct 8, 2023, 9:03 PM

#

Okay, and the path would just be /bin?

civic locust Oct 8, 2023, 9:04 PM

#

no, the PATH would be a bunch of different locations

#

https://utilities.up.railway.app/env-vars?prefix=PATH

umbral mango Oct 8, 2023, 9:05 PM

#

not the PATH for prince

#

the PATH for the binary file

#

wait

#

that's the same thing

umbral mango Oct 8, 2023, 9:06 PM

#

civic locust <https://utilities.up.railway.app/env-vars?prefix=PATH>

ah so how do I refer to this env?

#

or do I have to copy paste/

civic locust Oct 8, 2023, 9:06 PM

#

you dont need to, its just an example?

umbral mango Oct 8, 2023, 9:06 PM

#

I see

#

weird.

#

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

#

I had done this

civic locust Oct 8, 2023, 9:12 PM

#

no you cant

umbral mango Oct 8, 2023, 9:12 PM

#

yeah

#

realised now

umbral mango Oct 8, 2023, 9:14 PM

#

umbral mango But yeah a more critical error would be: `Error: Prince#execute: cannot resolve ...

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? 💀

civic locust Oct 8, 2023, 9:15 PM

#

did you put the binary in /bin ?

umbral mango Oct 8, 2023, 9:15 PM

#

updated toml:

#

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

umbral mango Oct 8, 2023, 9:15 PM

#

hehe

#

it can choose

civic locust Oct 8, 2023, 9:15 PM

#

not how it works

umbral mango Oct 8, 2023, 9:15 PM

#

that's valid bash, though

#

okay okay, so I do this? './${full_name}/install.sh /bin'

civic locust Oct 8, 2023, 9:16 PM

#

does it even need a path

umbral mango Oct 8, 2023, 9:17 PM

#

yes

civic locust Oct 8, 2023, 9:17 PM

#

it can decide itself

umbral mango Oct 8, 2023, 9:18 PM

#

base=$( dirname "$0" )

cd "$base" || exit 1```

#

this is a line inside install.sh

civic locust Oct 8, 2023, 9:18 PM

#

civic locust it can decide itself

Press Enter to accept the default directory or enter an alternative

umbral mango Oct 8, 2023, 9:18 PM

#

umbral mango ```sh base=$( dirname "$0" ) cd "$base" || exit 1```

wait then what is this

civic locust Oct 8, 2023, 9:19 PM

#

did you write this?

umbral mango Oct 8, 2023, 9:20 PM

yes

#

a long while back

civic locust Oct 8, 2023, 9:20 PM

#

umbral mango updated toml: ```toml # https://nixpacks.com/docs/configuration/file [variables...

who wrote this then

umbral mango Oct 8, 2023, 9:21 PM

#

also me

civic locust Oct 8, 2023, 9:21 PM

#

🤨

umbral mango Oct 8, 2023, 9:21 PM

#

what are you raising brows for

#

It's 3 AM, I'm not usually this stupid

#

okay now

#

I didn't pass a path

umbral mango Oct 8, 2023, 9:23 PM

#

civic locust `Press Enter to accept the default directory or enter an alternative`

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

civic locust Oct 8, 2023, 9:25 PM

#

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

umbral mango Oct 8, 2023, 9:26 PM

#

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

civic locust Oct 8, 2023, 9:27 PM

#

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

umbral mango Oct 8, 2023, 9:28 PM

#

yes

#

so it is in /usr/local thonk

#

that's the prefix

#

so /usr/local/bin

#

hmm

civic locust Oct 8, 2023, 9:29 PM

#

umbral mango so `/usr/local/bin`

should be

#

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

umbral mango Oct 8, 2023, 9:30 PM

#

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.

#

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.

civic locust Oct 8, 2023, 9:34 PM

#

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

umbral mango Oct 8, 2023, 9:34 PM

#

there is nothing to use?

#

it doesn't specify anything I'm supposed to do to install prince automatically

civic locust Oct 8, 2023, 9:35 PM

#

read their docs?

umbral mango Oct 8, 2023, 9:35 PM

#

they don't have docs IIRC

civic locust Oct 8, 2023, 9:35 PM

#

read the source code?

umbral mango Oct 8, 2023, 9:35 PM

#

this readme is all they have

#

lol ok

umbral mango Oct 8, 2023, 9:43 PM

#

civic locust read the source code?

Should be this https://github.com/rse/node-prince/blob/master/prince-npm.js#L292-L300

civic locust Oct 8, 2023, 9:44 PM

#

but how do you run the download

umbral mango Oct 8, 2023, 9:46 PM

#

umbral mango here's what the docs for the package say: ``` Prince#binary(binary): Prince: set...

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

civic locust Oct 8, 2023, 9:48 PM

#

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

umbral mango Oct 8, 2023, 9:49 PM

#

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

civic locust Oct 8, 2023, 9:50 PM

#

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

umbral mango Oct 8, 2023, 9:52 PM

#

but it doesn't

why so?

I was asking why /bin specifically
