I'm learning Openresty for a small web app. Is there an abstraction layer Lua web apps and frameworks? For example: Python/WSGI, Ruby/Rack, Elixir/Plug.
The most recent one I found for Lua seems out-of-date: APItools/lua-resty-rack
There is also WSAPI and WSAPI-Openresty, but I couldn't find any maintained middleware/projects that utilize it.
Do Openresty apps simply not use this type of abstraction layer for most production apps? Or is it not needed because of the Openresty architecture?
