How can I invoke npm on heroku command line (to install bower components)?

Question

Bower is for client side Javascript what npm is for the server side and reads a component.json file to recognize dependencies that should be fetched at deploy t

Answer 1

You can also setup a postintall command, something like this in your package.json

"dependencies": {
    "bower": "0.6.x"
},
"scripts": {
    "postinstall": "./node_modules/bower/bin/bower install"
}

Then npm install will also install bower dependencies.

Pros : one command to rule them all.

Cons : you unnecessarily embed bower as a dependency.

Answer 2

You can use run like this:

heroku run npm install git://github.com/webjay/kaiseki

Answer 3

You can use bower directly like this

"dependencies": {
    "bower": "^1.7.9"
},
"scripts": {
    "postinstall": "sudo bower install --allow-root "
}

Answer 4

You should declare NPM dependencies in the package.json file

All you install from shell will be deleted on exit shell. You are in a cloned instance.
