Do you develop your app on your laptop/desktop without Docker?

package-lock.json is generated when you run npm install and this Dockerfile assumes that npm install was run at least once on your laptop/desktop.

Thanks, I realised it was listed in the dockerignore file, i was able to have it deployed but now the app has refused to spart, its always suspending after successful build and deploy.

That’s odd. Can you check fly logs?
