Angular provides a standard .htaccess to be used in Angular applications.

RewriteEngine On
# If an existing asset or directory is requested go to it as it is
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -f [OR]
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -d
RewriteRule ^ - [L]

# If the requested resource doesn't exist, use index.html
RewriteRule ^ /index.html

It is useful for routes to be accessible via direct access or refresh.

However, a directory that is within the same Angular directory is always redirected to index.html.

This directory contains the API in CodeIgniter 3 that is called by the Angular application.
And it is located in /example.com/api/...

Everything in the root of example.com is Angular’s html and JS.

How do I stop .htaccess from redirecting when there is /api/ in the URL?
Eg: /api/index.php/controller/method
