React app is looking for static files in different location when using proxy
Building for relative paths for create-react-app
There can be two places where you could define relative path
1) By default, Create React App produces a build assuming your app is hosted at the server root. To override this, specify the homepage in your package.json, for example:
"homepage": "http://mywebsite.com/react_app",
This will let Create React App correctly infer the root path to use in the generated HTML file.
2) If you are using react-router@^4, relative path can be set using basename
<Router history={browserHistory} basename={'react_app'}>
<Route path="/" component={App} />
</Router>
Hope that helps!!!
where did you store assets? If it is not the public folder, I think you should take a look at https://create-react-app.dev/docs/using-the-public-folder
You have to add base tag(URL):
<html>
<head>
<base href="./react_app" target="_blank" />
</head>
...
</html>
