npm install vs. edit package.json and npm update

Curious what is the difference between the two procedures:

npm install xyz
edit package.json, adding required module names like this:

"dependencies": {
    "express": "~3.4.4",
    "mongodb": "*",
    "body-parser": "*",
    "bson": "*"
  },

and then npm update

If you just do npm install package, it doesn't add it to your package.json. Then, if you want to npm update or publish your package, it won't have all of the required packages.

You can also do npm install --save package, which will install and add to your package.json. (see the docs)
