Unexpected error arises in Typescript despite code functioning properly

As part of a practice project where I'm focusing on using webpack, ES6, npm and Typescript implementation, I have successfully set up loaders for 'awesome-typescript-loader' and 'babel-loader', which are bundling the code properly.

However, when testing this snippet:

document.getElementById('test-id').innerHTML = 'asdf';

I encounter an error in the browser console, even though the code is working as intended and injecting the string 'asdf' into the specified ID.

I've attempted switching to the alternative loader 'ts-loader', using querySelector() instead of getElementById(), assigning the element to a variable before setting the .innerHTML, but none of these solutions have resolved the issue.

Answer №1

As predicted by casraf, the solution to this issue was discovering that the script was executing twice - once before and once after the DOM had fully loaded.

In my situation, I was utilizing html-webpack-plugin to manage script injections, but I had inadvertently left a hardcoded copy in my index.html file. The problem was resolved by removing the hardcoded link altogether.
