Deploying a Node js app from a turbo monorepo

I'm just trying to figure out if there are any docs on that. Having a relatively hard time with it; neither turbo nor railway has any info on it. I can't break up the repo as it's an important architecture choice we made. I can't be the first to want to do this, lol. 😓

does this help? https://docs.railway.app/deploy/monorepo

alex.lazarOP•2y ago

not exactly, I already set the root directory and the build/start command. Problem is I'd also need to set a custom install command as the app I am deploying is dependant on some other packages

Brody•2y ago

shouldn't those packages be in your package.json?

alex.lazarOP•2y ago

For context, this is what we did for Vercel for our next app and it worked

alex.lazarOP•2y ago

the packages are in package.json indeed, but there's some code (prisma) that gets generated postinstall said code is used across apps and packages

Brody•2y ago

are you wanting to deploy a frontend to railway?

alex.lazarOP•2y ago

Nope, just the backend We need a service that runs cron jobs to manipulate data

Brody•2y ago

gotcha i think i can make this happen

alex.lazarOP•2y ago

Hey, any pointers and I'm more than happy tbh

Brody•2y ago

build command: install command: start command:

alex.lazarOP•2y ago

Not sure I get it 🧐

Brody•2y ago

fill those out 🙂

alex.lazarOP•2y ago

oh, suree build command: cd ../.. && yarn build --filter=data... install command: cd ../.. && yarn install We actually don't have a start command and it dawns on me this may be an issue? lol

Brody•2y ago

haha yeah no start command means app wont start

alex.lazarOP•2y ago

I looked in the logs though, and it doesn't get to that point anyway though

Brody•2y ago

well yes but i still need one

alex.lazarOP•2y ago

the error happens when trying to import one of the packages 'db-queries@*' is not in this registry. true that my bad, the start command is there, within the data workspace. just not in monorepo root

Brody•2y ago

and i will also need your railway.json file, this can be found in the details tab of a deployment

alex.lazarOP•2y ago

so start command would be: yarn start

Brody•2y ago

but i need the start command lol ah okay

alex.lazarOP•2y ago

yeah, basically since it's local we don't need to exit the app dir sure thing

    "builder": "NIXPACKS",
    "buildCommand": "cd ../../ && yarn build --filter=data..."
  },
  "deploy": {
    "numReplicas": 1,
    "restartPolicyType": "ON_FAILURE",

  }
}

{
  "$schema": "https://railway.app/railway.schema.json",
  "build": {

}

ohh, I see, we just need to specify commands here right? This is actually pretty cool and easy so, I'd have:

{
  "$schema": "https://railway.app/railway.schema.json",
  "build": {
    "builder": "NIXPACKS",
    "buildCommand": "cd ../../ && yarn build --filter=data...",
    "installCommand": "cd ../.. && yarn install",
    "startCommand": "yarn start"
  },
  "deploy": {
    "numReplicas": 1,
    "restartPolicyType": "ON_FAILURE",
    "restartPolicyMaxRetries": 10
  }
}

{
  "$schema": "https://railway.app/railway.schema.json",
  "build": {
    "builder": "NIXPACKS",
    "buildCommand": "cd ../../ && yarn build --filter=data...",
    "installCommand": "cd ../.. && yarn install",
    "startCommand": "yarn start"
  },
  "deploy": {
    "numReplicas": 1,
    "restartPolicyType": "ON_FAILURE",
    "restartPolicyMaxRetries": 10
  }
}

right?

Brody•2y ago

nope

    }
  },

untested, i dont know anything about your app, ive just made the railway.json with the commands you gave me

alex.lazarOP•2y ago

Sounds good to me Any docs on this in case I need to further play with it without bothering anybody?

Brody•2y ago

wait thats wrong fixed

alex.lazarOP•2y ago

what was wrong?

Brody•2y ago

forgot dependsOn to make sure isntall runs after setup and before start

alex.lazarOP•2y ago

oh, okay Thanks!

Brody•2y ago

there are some lackluster docs here, they dont cover anything i just did though https://docs.railway.app/deploy/config-as-code#json how i know how to do this then? i read the schema and vscode will auto complete for me

Brody•2y ago

like so

alex.lazarOP•2y ago

vscode will auto complete for me

github copilot is AMAZING EDIT: aaaand, that's not what happened lol

Brody•2y ago

i dont use copilot the schema auto complete is a native vscode feature

alex.lazarOP•2y ago

that said, it unfortunately still fails with the same error 😓 apparently it's trying to install db-queries (a local package) from npm weird

Brody•2y ago

id need to see the repo to make any further recommendations, im not even a js dev

alex.lazarOP•2y ago

I have an idea to change the way the packages get built and imported, but it's more work than I can do now (4 am here) Can we keep this post open until tomorrow?

Brody•2y ago

of course

alex.lazarOP•2y ago

P.S.: I didn't expect a quick answer when I opened this

Brody•2y ago

🙂

alex.lazarOP•2y ago

I'll come back to you after I try that tomorrow. Here's hoping. Thanks for the help Brody 🙏🏻

Brody•2y ago

no problem 🙂

alex.lazarOP•2y ago

I have a potentially stupid guess that the issue may happen because railway tries to install packages with Nixpacks and our repo uses yarn workspaces 🧐

Brody•2y ago

nixpacks is a app builder, not a package manager

alex.lazarOP•2y ago

ruled that out then

Brody•2y ago

lol

alex.lazarOP•2y ago

So my idea of bundling the underlying packages with tsup didn't work, and it cost me half a day, lol. Scratched all that 😓

Brody•2y ago

I'm out of ideas too

alex.lazarOP•2y ago

well, let's hope the weekend bestows me with new ideas. Thanks a lot for the help Brody

Brody•2y ago

no problem
