Local or Private NPM module when deploying to Heroku
问题 I have a node app that has a local npm module npm link ./local and I'm trying to deploy the app to heroku. Heroku runs npm install when I deploy, but npm link 's aren't saved in package.json so my local module is missing. I'm new to heroku and Procfiles , I'd like to run a script or just run npm link ./local before on the heroku box. Alternatively I could put the module on github as a private repository and link it from there. But as far as I know Heroku isn't able to download private repo.
