A minimal Typescript example with Tesseract.js can be found here. Tesseract.js supports both browsers and Node.js, with only slight differences between the versions. The types file includes types from both. It looks like the issue here is that you are building a project for Node.js, and the compiler is throwing an error for all of the types that only exist for browsers.

Based on my very limited understanding of Typescript, I believe that this is probably an issue with the project/build configuration, and that the tsconfig.json can be modified such that it does not throw errors for types that exist in browsers. However, let me know if you investigate further and find this is not the case, and that some change is required in this repo, and we can discuss further.

I've found that you are correct, this is an issue of browser only code being in an environment I had setup not to support that.
in my tsconfig.json I had

{
	"compilerOptions:{
		...
		"lib": [
      		"ESNext",
    	],
    	...
	}
}

Adding "DOM" to the list of typescript libraries corrects the issue.
I'm not sure why I was not getting this error a week ago. Thank you for the input.
