I volunteer to teach an intro to Rails class to folks getting ready to graduate a local code school and always enjoy watching their facial expressions as I live demo in about 15 min what they just spend the last couple months learning how to implement in the node/JS stack.
Plus, Ruby is just a joy to work with. Hard to put a price on enjoying the language and framework you work with.
As a side point though, it is much less mature than rails.
Just going off the age, and number of: commits/releases/contributors.
Its GitHub pulse is also obviously not as “rapid”
Rails also has a rich set of libraries in the form of gems - which AdonisJs most likely doesn’t rival
Rails is also used/has been used in production by some major companies. Perhaps AdonisJs has been too, but it can’t be as many
Nest has a bit more mindshare right now - with Triplebyte, etc using them
The good part is that it uses Express under the hood (which probably is ending up becoming the Rack of JavaScript middleware) ...so you get the third party ecosystem compatibility.
