How to host a React app with routing?

Question

Apache HTTP Server

I have a React application with routing (react-router-dom) and FireBase. And there is so far a test hosting (Apache). I made a build yarn run buildand uploaded it to hosting. The main page opens, and when you enter site.ru/admin, 404 comes out.
I threw all possible .htaccess options, but to no avail.
Tell me how to implement it correctly so that routing works.

Answer 1

Have you tried this .htaccess option? Helped me.

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /subdirectory
RewriteRule ^index\.html$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-l
RewriteRule . /index.html [L]
</IfModule>

If it doesn't help, then check if any .htaccess rules are processed at all.
If not, then write to the hosting admins. Sometimes the server is configured in such a way that the settings from .htaccess do not work in whole or in part.
