How to write encode function on node.js by passing input argument from X3

Node.js files contain tasks that will be executed on certain events. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices. Node.js applications are written in JavaScript, and can be run within the Node.js runtime.Node.js files have extension “._js”

STEP1: Creating Node.js File and save it as gumu.js

Writing Node.js code with build in modules and user defined modules and save it on Root Drive:\Sage\SyracuseComponent\syracuse\bin\node_modules\bundles\ greytrix\lib\gumu.js

Create the folder under bundles(greytrix\lib)

Fig 1.1-Code Description:

The “use strict” Directive:

“use strict”: Defines that JavaScript code should be executed in “strict mode”. It helps to write cleaner code, like preventing from using undeclared variables.

Built-in Modules:

To make Node.js act as an HTTP server include the module. Include the module using require() function with the name of the module.

Server:var http = require(‘http’);

Application has access to the HTTP module, and is able to create a server.

Node.js has a built-in module called HTTP, which allows Node.js to transfer data over the Hyper Text Transfer Protocol (HTTP).

To identity the httpclient we can declare

Client : var httpClient = require(‘syracuse-httpclient/lib/httpClient’);

Create user defined Modules:

Use the exports keyword to make properties and methods available outside the module file.

Example: exports.TOBASE64=function(_,InData){…..};

• Base 64_IN.

CALLB        

• Specify the location of callback function. This is needed only for ‘wait’ mode.
• The value depends on the function.
• -1 is the value to say that the callback location is the last parameter.

RETURNS
