Title:

Node.js (1)

Description:

Node.js is an open source, cross-platform runtime environment for server-side and networking applications. Node.js provides an event-driven architecture and a non-blocking I/O API that optimizes an application's throughput and scalability. These technologies are commonly used for real-time web applications. – PowerPoint PPT presentation

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

4
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

5
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

6
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
