In order to directly run Node.js® script code from a JS7 shell job script, the recommended approach is to use a shebang that runs Node.js® as the interpreter of the script like this:

Code Block

language	js
title	Example how run Node.js® script code with a shebang
linenumbers	true

#!/usr/bin/node

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

//print value of variable   
console.log( name);
console.log( num);

Alternatively, the Node.js® script can be executed from a file that has to be located within reach of the JS7 Agent that runs the job:

node /some/location/JS7-2.5.1/demo_Node.js

const fs = require('fs');
 
// fetch the env.* variables
var name = (process.env.name);
var num = parseInt(process.env.num);
 
// print value of variable   
console.log(name);
console.log(num);

// modify the values
var num1 = num + num;
console.log(num1);

var name1 = name + " This is JS7 ";
console.log(name1);

// pass results from key/value pairs that are appended to a temporary file provided by JS7
fs.appendFile(process.env.JS7_RETURN_VALUES, 'num1=' + num1 + '\n', (err) => {});
fs.appendFile(process.env.JS7_RETURN_VALUES, 'name1=' + name1 + '\n', (err) => {});
