My react is running fine on local host, but when I upload it online for ex : Heroku, Vercel, It only shows the react home screen "edit app.js". The app is not working.
It might be because your index.html file being hosted still has the boiler plate code. Based on how you're deploying your app, a html is usually created for you with some boiler plate (I know firebase does this for example).

I have this case where when clicked a link I redirect the user to the app using deep linking (made with RN) if the app is installed.
However, if the app is not installed instead of displaying error or a popup, I need to navigate to another route in the web, example: /web-login. I created the link for my app and it works, how do I test if the user has the app installed in the device, so then I can navigate to the other route if the user does't have it.
If the app is not installed I get something like: Browser cannot open the page because the address is invalid.

I've got a React app running on Azure. It runs fine in my localhost, however, when I go to the Azure address, it doesn't load; all I get is a blank page with a head and body html element, which is throwing the following error:
Uncaught SyntaxError: Unexpected token <
The immediate question, of course, is what's causing the error and how do I fix it?
The bigger question in the background is, with a backend app, I can enable logging and look at a log stream and see what's throwing errors in real time. With a frontend app, the errors are happening in my browser; the React Chrome extension doesn't even recognize this as a React app. How do I debug in this context?
