How to find out if new versions of npm-packages exists

Question

I have a package.json that contains the following settings for the dependencies:

"dependencies": {
  "bootstrap": "3.1.1",
  "electron": "1.3.1"
}

I know there are newer versions for boostrap and electron.

I was asking myself: Is there a way to find out if newer versions of the dependencies exists?

In Bower.io I would sipmly run bower list which lists installed packages and possible updates and then run bower update -S to install the updates.

Is there similar workflow in npm?

A way that directly installs newer versions is

"dependencies": {
  "bootstrap": "^3.1.1",
  "electron": "^1.3.1"
}

and running npm up. But there seems to be no command that only lists possible updates for the packages.
