JavaScript Finds Its Place In Enterprise Software Development

Adoption of JavaScript — and the Node.js runtime environment in particular — sets the stage for the biggest shift in enterprise application development in more than a decade

Node.js Facts & HistoryNPM

  • Node Package Manager
  • Since 2011
  • ~183.000 Modules at
  • package.json describes the project
  • Fetches dependencies described in package.json
  • Compiles native addons for the platform
  • Consider private NPM repositories!
  • NPM 3.3.6 (since Node.js 5.0.0 with better Dependency Resolution)

Installation and Configuration

Installation and ConfigurationInstallation

  • Linux: Install with your favorite Linux Package Manager (YUM, APT etc.)
    • Packages often out of date! YUM EPL will install Node.js 0.10.x
  • Download from
  • Use NVM before installing Node.js/NPM (Node Version Manager)
  • Get the official Docker image

Installation and ConfigurationConfiguration

  • npm config
  • npm config get [<key>]
  • npm config set <key> <value>
  • npm config edit (Open Sesame!)
  • npm -g for global configuration

Installation and ConfigurationMy Windows configuration (Shame on me!)

D:\node-slides>npm config list

; cli configs
user-agent = "npm/2.15.8 node/v4.4.7 win32 x64"

; userconfig C:\Users\sskoczyl\.npmrc
msvs_version = "2015"
proxy = ""
python = "python2.7"

; globalconfig C:\Users\sskoczyl\AppData\Roaming\npm\etc\npmrc

; builtin config undefined
prefix = "C:\\Users\\sskoczyl\\AppData\\Roaming\\npm"

; node bin location = C:\Program Files\nodejs\node.exe
; cwd = D:\node-slides
; HOME = C:\Users\sskoczyl
; 'npm config ls -l' to show all defaults.
Bad prefix!
npm config get prefix
Better prefix! (add to PATH)
npm config set prefix $HOME/.node_modules_global
npm config set prefix %userprofile%\node_modules_global

Installation and ConfigurationProject Setup

D:\node-slides>npm init
This utility will walk you through creating a package.json file.
It only covers the most common items, and tries to guess sensible defaults.

See `npm help json` for definitive documentation on these fields
and exactly what they do.

Use `npm install <pkg> --save` afterwards to install a package and
save it as a dependency in the package.json file.
