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.

Unix

• Find the below examples for download (.json upload): run-Node.js-unix.workflow.json

• In order to directly run Node.js® script code from a JS7 shell job script the recommended approach is to use a shebang like this:

...

• 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);

• As a bad alternative the Node.js® executable can be invoked directly and can be parameterized like this
• Node.js® script can be executed from a file that has to be located by the executing Agent:

...

...

node  /home/{User}/JS7-2.5.1/

...

demo_Node.js

Windows

• powershell-windows.workflow.json

• In order to directly run Node.js® script code from a JS7 shell job script the recommended approach is to use a shebang replacement like this:

• linenumbers true

  @@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:

  • • Credits for the shebang replacement to How to run a PowerShell script within a Windows batch file
    • 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 pwsh
    • The Node.js®node.exe executable is available starting with node.js that can be used with the shebang accordingly.
