The Node.js Environment

• A runtime environment platform built on Chrome's
  JavaScript runtime
• Acts as a library for executing JavaScript on the
  server-side
• Uses Google V8, Googles open source JavaScript
  engine to execute code
• Runs equally well on Linux and Windows operating
  systems

Features of Node.js

• The event-driven model used by Node.js is a
  non-blocking I/O model
• Gives excellent results for real-time
  applications installed on distributed systems
• Supports varied devices
• Increase efficiency and maximize throughput by
  using non-blocking I/O and asynchronous events
• The file and network events are multi threaded
  but the applications run on a single-thread

The Features of node.js

• The asynchronous nature enables Node.js to
  support real time applications with built-in
  asynchronous I/O libraries for
• File
• Socket
• HTTP communication
• These features eliminate the need of any
  server-side software and Node.js acts as server
  software itself
• Renders a higher degree of user satisfaction by
  handling multiple client connections at the same
  time

The Node Security Project

• Integration of Node.js applications with
  JavaScript prevents security threats and attacks
• The Node Security Project is a Node.js community,
  with three basic targets-
• Audit npm -Node packaged modules
• Generate advisories to fix the modules
• publish public API and audit results
