how to use slide.pageNumber() slides methods from pptxgenjs library

Question

I am using PPTxgenjs library. I want to show page number/slide number with my title like this [Dashboard Reporting (Page 1...)] on each slide. I tried Slide methods.

var pptx = null;
pptx=new PptxGenJS();
var slide=pptx.addNewSlide();
var slideNum=slide.pageNumber();

but it's giving me error

slide.pageNumber() is not a function.

Answer 1

You can use like

var slide=pptx.addNewSlide();
slide1.slideNumber({ x:'50%', y:'95%', color:'0088CC' });

where x and y are slide1's position. You can set it with your title position.
