P5.JS & jsPDF cant use 2.4.0 but 1.3.3 works

Seems like this is a common case for UMD packed files.

That is, they have a namespace object which wraps up their actual main constructor.

For the jsPDF library we have a namespace jspdf and a main constructor jsPDF inside jspdf.

I had to do the same for the ml-matrix library:

Autocomplete and documentation for "imported" p5js

When we use import in JS 2 things happen: The file becomes a JS module and it needs a <script type=module> to load inside the HTML. JS checks the import line if a file w/ that exactly path & name exists so it can load it as a module. As we can note the file “ml-matrix” doesn’t exist. Instead there are “matrix.js” & “matrix.umd.js”. However neither is a JS module but just vanilla JS code. The library’s types is called “matrix.d.ts”. But to make things worse “matrix.umd.js” is exposed as …

In its UMD format ml-matrix has a namespace mlMatrix and a constructor Matrix inside mlMatrix:
