Heroku requires a package.json and a lockfile in the root of the repository or they will fail the deploy.

However you can set up a package.json in the root of the repo which installs dependencies for the subdirectories and runs their related commands.

Using yarn for example, in your case you could put an empty yarn.lock in the root and a package.json like:

{
  "name": "my-project",
  "version": "0.1.0",
  "private": true,
  "scripts": {
    "postinstall": "yarn --cwd server --production=false install",
    "build": "yarn --cwd server serve"
  }
}

The --production=false ensures that devDependencies will be installed, which otherwise wouldn't happen since NODE_ENV is set to production in Heroku's environment.
