Why Node.js required in Angular over Internet Information Services

What is Node.Js?

• Node.js is an open source server framework

• Node.js is free

• Node.js runs on various platforms (Windows, Linux, Unix, Mac OS X, etc.)

• Node.js uses JavaScript on the server

What Can Node.js Do?

• Node.js can generate dynamic page content

• Node.js can create, open, read, write, delete, and close files on the server

• Node.js can collect form data

• Node.js can add, delete, modify data in your database

Why Node.js?

• A common task for a web server can be to open a file on the server and return the content to the client

Here is how PHP or ASP handles a file request:

• Sends the task to the computer's file system.

• Waits while the file system opens and reads the file.

• Returns the content to the client.

• Ready to handle the next request.

Here is how Node.js handles a file request:

• Sends the task to the computer's file system.

• Ready to handle the next request.

• When the file system has opened and read the file, the server returns the content to the client.

Advantages of Node.js:

• Node.js eliminates the waiting, and simply continues with the next request.

• Node.js runs single-threaded, non-blocking, asynchronously programming, which is very memory efficient.
