nodejs hosting from my laptop

I have a website that uses nodejs with express. The website is working fine on my localhost. I am not able to find a way to host the website from my laptop i.e. allowing external users to connect to it remotely. I wanted to check if this is possible. I am using windows 7.

I used to do the same job with php however, I used wamp server. Is there a similar way for nodejs?

Thank you
