OpenResty is fine for just that... REST interfaces.

If you're making an entire web application with a lot of front-end code that is already written in Javascript it is an added cost to also support C and Lua.

A lot of important development time can be retained by not having to write the same functionality in multiple languages.

A module can be written in Javascript and used on both the client AND the server.

Don't conflate mainstream media fashion with the sort of pragmatic convergence that has been a big part of driving the adoption of node.

"Raw speed" over everything else is the Yngwie Malmsteen of programming language metrics.

I do hear people saying that code can be reused across client and server but I don't find many examples of it. I understand that using one programming language for both client and server is really good as there is no context switch but I don't think that there can be much code can be shared between client and the server.

Also you don't need to program entire application in open resty. Just the idea of using lua instead of nginx mini- language for the config files can be a good enough reason to give it a try. Every body uses nginx anyways for their front end, no?
