I am using an NX mono repository for my project. It contains the following three applications:
I was trying to deploy the backend code to Heroku and I am facing the issue of it not finding the packages when I set the NODE_ENV variable to production. All of the NX packages are stored as the dev dependencies as default. It works fine if I set the NODE_ENV to development.
Question: What is the ideal way of solving the issue? I do not want to set NODE_ENV to development because otherwise, it will slow the deployments by installing useless packages from the devDependencies.
Any help will be appreciated.
This is what my package.json looks like.

And this is my Procfile:
web: yarn build:api && yarn api:prod
Nx is installed as a devDependency. Heroku scrubs devDependencies after thebuild step so that you don't have extra dependencies for your final environment. What you should do is have a build script in your package.json that builds everything your server will need to start, and then have a start script that starts the application, or set the web property in the Procfile as you currently have done for the build:api && api:prod. However, this start script should not rely on any devDependencies. It should be able to run with just the production dependencies.
