Since I began to develop a big application as a Rails engine I have been noticing some annoying things, especially with gems.
First is Spring. Since it’s a core gem I would expect it to be well supported for engines, but it’s not. I opened two issues, one about not working fast enough and another about problems running the Rails server. Both were opened on July 2014.
The second gem is jquery-ui-rails, which does not seem to work with engines.
Why are these things happening? Aren’t engines good enough to be considered as first-class citizens?
