How to outline text in illustrator scripting

var docRef = app.activeDocument;

var colorForText = new CMYKColor();
    colorForText.black = 0;
    colorForText.cyan = 0;
    colorForText.magenta = 0;
    colorForText.yellow = 0;
    
var colorForTextOutline = new CMYKColor();
colorForTextOutline.black = 100;
colorForTextOutline.cyan = 0;
colorForTextOutline.magenta = 0;
colorForTextOutline.yellow = 0;


var outlineSize = 5;


for (i = docRef.textFrames.length-1; i >=0; i--) {
    
    for (j = 0; j < docRef.textFrames.words.length; j++){

        docRef.textFrames.words.filled = true;

        docRef.textFrames.words.fillColor = colorForText;

    }
    
var outline = docRef.textFrames.duplicate(docRef, ElementPlacement.PLACEATEND);



    for (h = 0; h < outline.words.length; h++) {
        outline.words.filled = true;
        outline.words.fillColor = colorForTextOutline;
        outline.words.stroked = true;
        outline.words.strokeColor = colorForTextOutline;
        outline.words.strokeWeight = outlineSize;
        
        }
//docRef.textFrames.createOutline();

//outline.createOutline();
    }

createOutline(); converts live text to outlines, if you are trying to just create a stroke you have to go about it a different way. This script will take the text and copy it, put it in back, and put a stroke behind on the behind text so it has an effect similar to an offset path. The way I have it leaves the text live, if you were wanting to convert the text to outlines as well I left that part written in the bottom of the script. There is also a StrokeJoin parameter as well.

Hope this helps!

#target illustrator



var idoc = app.activeDocument;
var tf = idoc.textFrames;


for ( t = tf.length-1; t >= 0; t-- ) {
  var text = tf;
  text.createOutline();
}


alert ( "All text converted to outlines." );
