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:

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:
