JavaScript/Node.js script

This action supports the full JavaScript language, unlike JS Script and JS Evaluate actions. JS Script and JS Evaluate actions use the system script engine and support a fairly simplified language.

By default, the JavaScript/Node.js script action uses the preinstalled node.js engine that comes with RoboTask. You can also use any other node.js kit installed and customized to your needs. The script can interact with RoboTask using the RoboTask object for node.js

You can find the language description here and the node.js objects description here.




Toolbar buttons

Save and Exit - saves task settings and closes the editor

Cancel - closes the editor without saving

Open - opens the script text from the external text file and places it into the script text editor.

Save as - saves the script text to an external file.

Add var - calls the variable selection window and places the variable call at the current cursor position.


Script Mode

There are two options

Execute inline script - execute the script you have written in the script editor. In this case, you will see the text editor.

Execute external script - run the script from an external file.


Expand variables

Check this box if you want to expand RoboTask variables in the script body before running the script. With variables, you can create dynamic text depending on different conditions.



In "Execute inline script" mode, it is a script text editor.

In "Execute External script" mode, it is a field to enter the file name and a file selection button.






Assign exit code to a variable

Enter the variable name to save the script exit code. By default, the exit code is 0, but it can be changed in the script.


Assign script output to a variable

Enter a variable name in this field to write the script's output text stream to a variable. You will then be able to process this text in your task.


Node.js interpreter

Use Embedded Node.js - use the default Node.js engine that comes with RoboTask.

Use Specified Node.js - use your Node.js package. You can have several Node.js packages configured for different tasks.


Command line template

A command line template is needed to be able to pass custom parameters to the script. The template must contain two mandatory predefined parameters:

[InterpreterPath] - path to the interpreter module to be executed

[ScriptPath] - path to the script file

Both parameters are formed automatically.


Module search paths

Here you can set the search paths to additional Node.js modules (which are included in the script with the require command).
