Echo JS 0.11.0

I've been working a lot with data integration with legacy systems/customer systems with some that had issues handling JSON, so I've build this tools which revolve around basically a query language for data transformation (xml,json,csv and custom adapters,more to come)
I've been playing with it and creating scenarios, from simple ones to others that are less intuitive (like building a backend using its auto-openapi and a layer of basic queries to expose crud apis) and it does have potential, for me.
Curious if the idea could be interesting for others!
