Problem
How to remove URL # from Angular apps and allow page refreshing.
Solution
Create a .htaccess at root with the following, replacing "sub-folder" with the name of your parent directory. If you’re app lives at localhost/web server root, you won’t have a parent directory, so remove "/sub-folder" from the last line, leaving just /index.html.
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
RewriteRule ^(.*) /sub-folder/index.html [NC,L]
Set $locationProvider.html5Mode(true); in your route config.
Define a base URL in your index.html that matches your project sub-folder: <base href="/sub-folder/" />. If at root, your base will be <base href="/" />.
