• In order to directly run Node.js®   script code from a JS7 shell job script the recommended approach , the recommended approach is to use a shebang that can be invoked directly and can be parameterized 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);

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

• In order to directly run Node.js® js® script code from a JS7 shell job script the recommended approach , the recommended approach is to use a shebang replacement that can be invoked directly and can be parameterized like this:

  Code Block
  language js title Example how run PowerShell® script code with a shebang replacement 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);

  • • 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 pwshNode
    • 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:

  node.exe C:\Users\Documents\demo_Node.js
