How can i access my nodejs backend api from outside?

My backend seems to be deployed, but I can't find correct url that i can use. I own a domain that is currently aimed elsewhere (on render.com). I wanted to test the deployed backend before switching up domains. Is the node.js available on some public url? Where can I find it?

Go to service detail, click on "Subdomain & domain & IP access"

enable subdomain, domain or direct access with IP address this requires port to be exposed with httpSupport set to true (if you want to use subdomain / domain), e.g. https://github.com/zeropsio/recipe-nodejs/blob/main/zerops.yml#L16-L18

BTW if you only want to deploy the contents of the backend directory, use backend/~, then cd is not needed. Your application is not currently running. That's why there is http code 502 on the zerops subdomain.

zerops:
  setup: nodejs
  build:
      os: alpine
      base: nodejs@22
      buildCommands:
          - ls -la
          - cd backend && npm i
      deployFiles:
          - backend/~
      cache:
          - backend/node_modules
          - backend/package-lock.json
  run:
      os: alpine
      base: nodejs@22
      start: node src/app.js
      ports:
          - port: 3000
            httpSupport: true

you can always confirm whether the app is actually running in the runtime log .. 502 on subdomain usually either means the app is not running (would show up in runtime log), or it's not properly exposed (needs to run on 0.0.0.0 host and on the same port you've defined in zerops.yml)

found the url, thank you oh wow, you even checked my account and project. I have applied your suggested changes and the bakcend is now correctly running. Amazing support. Thank you.
