Node.js By SPEC INDIA
Node.js
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, Google’s 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 nonblocking 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
