Deploying angular 2 App (angular cli) to heroku

Question

I built and angular 2 app with angular cli ng build command works totally fine, it creates the dist folder.

In order to deploy it I followed this tutorial Deploy angular 2 app to heroku

When I follow all the steps, I type heroku open but I get an app error

ng: not found

log

here is my package.json file if you want to see it

It seems that is problem of angular-cli and his command ng but here in my package.json i have it

  },
  "devDependencies": {
  },
  "engines": {
    "node": "6.6.0",
    "npm": "3.10.3"
  }
}
`

One more thing, when I'm deploying I see installing components like @angular/common ... but no all of them.

any suggestion would be appreciated.

looks like your heroku app instance does not have angular-cli installed. I found a way to get it installed.

In your package JSON, add preinstall command like this

"scripts": {
    "start": "http-server",
    "lint": "tslint \"src/**/*.ts\"",
    "test": "ng test",
    "pree2e": "webdriver-manager update",
    "e2e": "protractor",
    "preinstall": "npm install -g angular-cli",
    "postinstall": "ng build && mv dist/* ."
  },

This will get angular-cli installed on heroku server and you will not get ng command not found related errors.
