I noticed that you uploaded your node_modules/ directory to your .git repository (which is usually not something you want to do), so I would at least create a file called .gitignore with the contents:
node_modules/
dist/
also, I’m not sure if the dist/index.html and dist/style.css files are generated from somewhere? If you put them there manually, it’s not a good idea to mix template files / content with the autogenerated content (specified with ‘outDir’ in the tsconfig.json). Also not sure if you intend to use the react framework in this project as well? (I only ask because I see some tsx loader code in the webpack config), so unless you also intend to pull in react & use it I would omit that code as well! (YAGNI! 
)
In fact, I would just say stick with just Typescript here (until you need webpack features), and I would just do ‘build tool’ stuff with a simple cp -R in an npm script (1 less dependency!), or even just have the static files (index.html) refer to build/export.js
Also, I just want to link to a nice blog post that I found useful about webpack: https://blog.andrewray.me/webpack-when-to-use-and-why/
hope this helps!
