openresty + SPA (single page application)

Hi

Is there any way to run server side js using openresty? and some way to deal with npm packages?

Creating complex frontends in SPA manner becomes a real pain without that...

OpenResty is currently Lua only (though people also use overlay
languages like MoonScript).

OpenResty will come with a package management tool and a central
repository site like CPAN.

The normal way is to proxy to Node.js server. It works just fine, and Nginx can proxy websockets there as well. You could have some features written in Lua running directly in OpenResty (inside Nginx worker process), and some other code in Node.js/Io.js. Then you have a polyglot environment. As a architecture it is a little bit more complex, but you gain access to some nice things in Node/Io ecosystem.

At last Nginx conference there was some talks about bringing _javascript_ to Nginx (but it looks like it might not be compatible with Node/Io and therefore with Npm for some of the packages).

You could try: https://github.com/tessel/colony-compiler to compile node/npm js to lua. Haven't tried it, just a really crazy idea :)

another one like that: https://github.com/PaulBernier/castl this one mentions luajit 2 (the default lua in openresty) as a target.

These probably won't work without many tweaks.

The normal way is to proxy to Node.js server.

Yet another way to do it is to build Node/Io part of the app as an API (rest/protocol buffers/cap'n proto/etc.) and then call that (async, well in OpenResty the code still looks like nice and clean synchronous, e.g. no call back hell) with cosockets in OpenResty Lua code.

Could you elaborate this a little bit? Why is it complex SPAs a pain with OpenResty + Lua on a server, and JS on a client (I find it rather easy, and Lua as a language is a lot nicer compared to JS in my opinion)? Yes, there could be some losses of code reusability (and there is currently repository huge as npm in Lua, LuaRocks comes the closest), but that's mainly with some utility functions that are usually easily replaced (Lodash/Underscore comes to mind). Client-side web is totally different runtime environment compared to server side (even with Node.js or Io.js). You can still manage client side assets and libs with npm or say bower in apps build with OpenResty.
