In Django? django.contrib.auth.views.password_reset seems like it would do the job, no? If you have specific logic you need to implement, rather than using the framework's default logic, there's likely not much it can do for you.

Alternatively, there appears to be a CBV version of password resets over here that looks fairly easy to extend: https://github.com/brutasse/django-password-reset

I can't talk for node.js (although I have found that its authn/authz frameworks are lacking in general) or various PHP frameworks, but Django at the least is fairly professional.
