Encountering a TypeError with Arg 1 while trying to execute the save method in jsPDF

I am currently working on a react project with a simple implementation of jsPDF. I am trying to execute the sample 'hello world' code but encountering an error when using the save method:

https://i.stack.imgur.com/o4FWh.png

My code is straightforward, first, I import the library like this:

import jsPDF from 'jspdf';

Then within a Component's click event function

<IOControls exportDrawing={this.exportDrawing} />

I have the following code:

exportDrawing() {
    const doc = new jsPDF();
    doc.text('Hello World!', 10, 10);
    console.log(doc); // shows an object
    doc.save('a4.pdf');
}

The error occurs on save() but I am unsure of the exact cause.

Any assistance would be greatly appreciated.

UPDATE I have realized that the code works fine if I call the methods at the root of my app component, the issue arises when it is called from other components.

Here is my setup

<App>
  <Sketch>
    <SketchControls>
    <IOControls>

exportDrawing() is declared in <Sketch> and triggered from a button in <IOControls>

Answer №1

element, I discovered that a method from a different library was causing a scope issue to arise. My current drawing engine is powered by the paperjs library. Specifically, I invoked the paper.install(window) method, which grants scope to the window DOM element. Interestingly, removing this invocation allowed for proper functionality of jspdf.
