Python with Node

Hello, We are having a bit of trouble providing a multi-service application that utilizes Node and Python on one of the services. The issue is nodenv is failing to install and then failing the subsequent npm install/build steps. Our nixpacks.toml: https://github.com/litestar-org/litestar-fullstack/blob/main/nixpacks.toml is there something we are missing?

👋 going to attempt a deploy now im getting OSError: Could not find a suitable TLS CA certificate bundle and thats a certi issue or whatever the package name is

Bad MessagesOP•13mo ago

The PR#101 is updating that package, I think each time they have an updated it breaks everyones stuff

Brody•13mo ago

indeed is does, but pr101 also has changes made to the nixpacks.toml file, can you revert those to the same nixpacks.toml in main?

Bad MessagesOP•13mo ago

Hmm it shouldnt anymore, i reverted them after testing

Brody•13mo ago

okay cool, looking

Bad MessagesOP•13mo ago

its time for the sleep, i will check back in the am to see the news

Bad MessagesOP•13mo ago

i think we can figure out that part :0. thanks! 😄

Brody•13mo ago

any questions on the changes I've made, since I did edit the litestar code and not just the nixpacks.toml perhaps there's a better way to skip that npm build assets function, since node is installed and the frontend is built in nixpacks, it both doesn't make sense to run that stuff again, and running it again causes errors

Bad MessagesOP•13mo ago

thank you. going to test it after my standup

Brody•13mo ago

sounds good!

Do you happen to know why redis and postgres are having these issues? Not sure if this is something to do with the volumes or the way i set up the services

initdb: error: directory "/var/lib/postgresql/data" exists but is not empty
...
initdb: detail: It contains a lost+found directory, perhaps due to it being a mount point.
initdb: hint: Using a mount point directly as the data directory is not recommended.
Create a subdirectory under the mount point.

Brody•13mo ago

are these from the standard deployments of the databases? + New > database > postgres / redis

Bad MessagesOP•13mo ago

yeah the only thing ive done is fix the first error on each (missing passwords) deleting them and the volumes and recreating seems to have worked this time actually

Brody•13mo ago

yeah was just gonna say, just deployed a postgres database and it worked

Bad MessagesOP•13mo ago

ty for your help again! 🙂

Brody•13mo ago

wanted to ask you about the database scheme thing, your framework requires the postgresql+asyncpg scheme, but the databases from railway come with just postgresql by default, do you plan to patch this away in your framework or update the database url in a template?

Bad MessagesOP•13mo ago

Yeah i just hit that.. I am not sure. It's kindve lame to not be able to use the dynamic URLs as they would change quite often I think? Is there a way to make ${{Postgres.DATABASE_URL}} use postgresql+asyncpg://?

Brody•13mo ago

if you plan to use a template, you can add a custom postgres service to your template and edit its DATABASE_URL and DATABASE_PRIVATE_URL scheme

Bad MessagesOP•13mo ago

ahhh

Brody•13mo ago

when i say "postgres service" i dont mean this, you cant edit the variables on the built in postgres database, you would need to add a postgres database as a service to the template

Brody•13mo ago

to add an editable postgres service to your template you can use this https://bookmarklets.up.railway.app/service-embed/

Bad MessagesOP•13mo ago

I might be dumb, how do i use this? Am i putting the shortcode for a postgres template to add to my template, or am i using the shortcode of my template and then pulling it from somewhere else? oh yeah, the 1st one. i was doing the 2nd ~~Oh man his is badass. I love railway 😅``~~

Brody•13mo ago

dont give railway credit for that lol i made it 😆

Bad MessagesOP•13mo ago

Oh man this is badass. I love Brody 😅

Brody•13mo ago

just be carefull, if you add a service you wont be able to remove it and i cant make a bookmarklet to remove a service since there is no api to do so
