Installing node.js and npm on Windows

Installation

Installing NodeJs and NPM can be done like any other windows application using the installer downloaded from Node.js website.

Steps

  1. Download the Windows installer package from Node.js website (nodejs.org).
  2. Run the downloaded msi package.
  3. Accept the license agreement and click NEXT a few times until you get below screen.
  4. Observe that Setup window shows following packages –
    • Node.js runtime (actual node executable)
    • npm package manager (that node package manager we discussed previously)
    • Online documentation shortcuts (few links to help)
    • Add to PATH (This makes node and npm commands to be executable from any path in command prompt.)
