Alan,
yes, NodeJS is suitable for this sort of application, but the answer gets more
ambiguous if you ask if it's the best option for you. Your application could be
served by Apache/Nginx+PHP/Perl/Python... I am not sure NodeJS offers something
for you that these others do not, though there is indeed the advantage you
mention of the thoroughgoing non-blocking nature of Node.
Personally, I think there are general advantages to NodeJS that make it
preferable to these alternatives for *most* [web] applications: a single client
and server side language, and that language being JavaScript, not some
heavy-handed OO beast, the Unix-like intuitive and lightweight nature of the
Node ecosystem, etc. Big complex languages and frameworks scare me, but not so
others.
I will caution though that some of the feeling of being lightweight is
deceptive, and you will find yourself stymied at times by the need to seek out
and cobble together primitives, the sparse documentation and some of the leaky
abstractions of the New Jersey approach (*). It's a learning experience.
