How To Build a web.config for a react app using azure + IISNode + express

Question

I built my react app after following this tutorial https://daveceddia.com/create-react-app-express-backend/ and https://daveceddia.com/deploy-react-express-app-heroku/. I know i'm not publishing to Heroku because I'm using an azure web app service, but due to the structure of my project I use a proxy to have the backend and front end hosted at the same time. When I run my app on localhost everything works fine and my react routing works so I know it's not an issue with my code. I have checked my logs and my requests hit the correct endpoints, however, none of my front end renders due to 403's, 500's and 404's. I have pin pointed it to my web.config file and I have no clue what it should look like. Some information about which file's I'm trying to render are here

heres the github repo as well incase this can help https://github.com/ecoulson/OverlakeASB

path to index.html: /client/public/index.html

path to frontend: /client

You might try adding

<globalModules>
<add name="iisnode" image="<path-to-iisnode.dll>" />
</globalModules>
