[dunkelheit]

I have used ngx_lua in the past for some intelligent query rewriting and was very pleased with the experience. It is definitely great having the power of real programming language at hand and not being constrained by yet another configuration file syntax. On the other hand lua just feels very small and the temptation to fit more of the application logic into web server is low (although apparently not for others as lapis shows ;)).

I guess nginScript is mainly an outreach thing. Apparently nginx developers have decided that all those UI developers are just more comfortable writing JS than anything else. What indeed raises some red flags is that it is a subset of the language running on custom VM. So it is in fact a JS dialect which will still require some amount of learning to use it effectively (no free javascript lunch here).
