How to redirect only the root path in nginx?

Question

I only want to redirect the root path from domain A to domain B. For example, if user type in https://www.a.com/ or https://www.a.com or http://a.com all redirect to https://www.b.com/, but if user type in https://www.a.com/something/ then it keep there without redirect.

I tried the following:

location / { return 301 https://www.b.com/; }

but it redirect all to www.b.com even user type in https://www.a.com/something/.

I found another similar solution, I think it is more concise:

location = / { return 301 http://www.b.com/; }

= / form appears more intuitive and perhaps has become canonical.

This should be the accepted answer as it is cleaner and more lightweight than the regex.

I got it.

location ~ ^/$ { return 301 https://www.b.com/; }

See other answer, no need for regex.
