How can I include two executables?

My NodeJS project needs Deno as well (to execute customer code in a sandbox). I can write a Dockerfile to use the node image and bring in the Deno executable, but I was wondering if this can be done in the dashboard, or in via a Nixpack config change? Here's the railway.json so far

{
  "$schema": "https://railway.app/railway.schema.json",
  "build": {
    "builder": "NIXPACKS",
    "buildCommand": "npm run build",
    "nixpacksPlan": {
      "providers": [
        "...",
        "deno"
      ]
    }
  },
  "deploy": {
    "numReplicas": 1,
    "startCommand": "HOST=0.0.0.0 npm run start",
    "sleepApplication": false,
    "restartPolicyType": "ON_FAILURE",
    "restartPolicyMaxRetries": 10
  }
}

{
  "$schema": "https://railway.app/railway.schema.json",
  "build": {
    "builder": "NIXPACKS",
    "buildCommand": "npm run build",
    "nixpacksPlan": {
      "providers": [
        "...",
        "deno"
      ]
    }
  },
  "deploy": {
    "numReplicas": 1,
    "startCommand": "HOST=0.0.0.0 npm run start",
    "sleepApplication": false,
    "restartPolicyType": "ON_FAILURE",
    "restartPolicyMaxRetries": 10
  }
}

Thanks. I see a build failure with this though. There's a conflict with the Deno executable. See this output.

Brody•4mo ago

i have updated this, please try again

scutifer•4mo ago

I'll try this, thanks. Alternatively, can we add an equivalent of the following into the JSON?

[phases.install]
  cmds=["...", "curl -fsSL https://deno.land/install.sh | sh"]

[phases.install]
  cmds=["...", "curl -fsSL https://deno.land/install.sh | sh"]

Brody•4mo ago

you can do something like that, but not in the install phase, that also uses incorrect syntax afaik

scutifer•4mo ago

I tried the cmd thing and it worked well! Here's the JSON if someone else needs it.

Brody•4mo ago

did the latest railway.json i gave not work?

scutifer•4mo ago

it didn't; it had the same error i.e conflicting Deno version dependencies

Brody•4mo ago

can you send the build logs from it

scutifer•4mo ago

yes, here it is
