JS: .htaccess для react-router

# If you are using Apache as your web server, you can insert this into your .htaccess file:

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

# I am using react: "^16.12.0" and react-router: "^5.1.2" This method is the Catch-all and is probably the easiest way to get you started.
