Basename not working properly

Question

I'm attempting to use a basename with react-router as documented on the react-router docs. This is due to base href being deprecated.

Here is what I have now:

import { Route, Router, useRouterHistory } from 'react-router';
import { createHistory } from 'history';
import { render } from 'react-dom';

var history = useRouterHistory(createHistory)({
  basename: '/subdirectory'
});

render(
  <Router history={history}>
    <Route path='/' component={App}>
      <Route path='next' component={Next} />
    </Route>
  </Router>,
  document.getElementById('root')
);

When I go to http://the-url.com/subdirectory the page loads as expected (rendering the App component). However, when going to http://the-url.com/subdirectory/next, I get a 404 error. My nginx config is:

location /subdirectory {
  alias /path/to/index.html;
  index index.html;
  try_files $uri $uri/ /path/to/index.html;
}

Here is how I managed to get it to work

Set Router basename to your subdirectory like this

<Router basename="/subdirectory">

If you used create-react-app and are building using npm run build you need to set homepage in package.json for the paths to be correct in the production build

homepage: "{http://www.the-url.com/subdirectory}"

For the nginx config, let's assume your index.html is under /path/to/subdirectory/index.html. Then the following should work

location /subdirectory {
    root /path/to;
    try_files $uri $uri/ /subdirectory/index.html;
}
