regular expression that has /admin in the middle and whole string ends with specific format

Question

I am trying to write a regular expression such as it has /admin in the middle and ends with .css or .js or other formats.

http://example.com/admin/static/style.css (SHOULD WORK)

http://example.com/admin/static/vendor.js (SHOULD WORK)

http://example.com/static/style.css (SHOULD NOT WORK)

I am trying to use this in nginx location block. I tried this

location /admin/\.(css|js)${ }

but not working.

Any ideas?

Where do you want to use it for what? What have you tried? How did this fail? — Sven

Migrate this to StackOverflow? But in the mean time see if this helps. — ShapeOfMatter

@ShapeOfMatter: Why migrating this? Writing regexes for web servers is a sysadmin topic... — Sven

The problem in your example is missing ~ after location. Without tilde, it is a simple prefix match, not a regex match. — Tero Kilkanen

What you may be missing is the section between "admin" and "css/js". This could work:

(.*)\/admin(.*)\.(css|js)

I also added the (.*) in the beginning, meaning that in front of /admin there may be additional characters.

Please try this for a case insensitive match (~*):

location ~* ^/admin/.+\.(css|js)$ { # more configuration }

Add other file types separated by | like ^/admin/.+\.(css|js|png|gif|jpe?g)$.
