Introduction

Node.js® is an open-source, cross-platform JavaScript runtime environment and is a frequently used scripting language available for Linux, MacOS, Windows, and other platforms.
This article explains how to syntactically include Node.js® scripts with JS7 job scripts.

In order to directly run Node.js® script code from a JS7 shell job script, the recommended approach is to use a shebang that can be invoked directly and can be parameterized like this:
Example how run Node.js® script code with a shebang
```
#!/usr/bin/node

var name =(process.env.name);
var num = parseInt(process.env.num);

//print value of variable   
console.log( name);
console.log( num);
```
As a another alternative, the Node.js® script can be executed from a file that has to be located by the executing Agent:

Example how to run Node.js® script code from a file

node  /home/{User}/JS7-2.5.1/demo_Node.js

In order to directly run Node.js® script code from a JS7 shell job script, the recommended approach is to use a shebang that can be invoked directly and can be parameterized like this:
Example how run PowerShell® script code with a shebang replacement
```
@@findstr/v "^@@f.*&" "%~f0"|node.exe -&goto:eof

var name =(process.env.name);
var num = parseInt(process.env.num);

//print value of variable   
console.log( name);
console.log( num);
```
Explanation:
- - If you consider this shebang replacement somewhat cryptic then add it to JS7 - Script Includes which are easily referenced from shell jobs, e.g. by using ##!include Node
  - The Node.js® node.exe executable is available starting with node.js that can be used with the shebang accordingly.
    e.g. @@findstr/v "^@@f.*&" "%~f0"|node.exe -&goto:eof
Last but not least a Node.js® script can be executed from a file that has to be located by the executing Agent:
Example how to run Node.js® script code from a file
```
node.exe C:\Users\Documents\demo_Node.js
```
