[erlang-questions] cowboy migration smooth path
Sun Nov 18 13:40:12 CET 2018
Upgrading just Ranch, no problem.
Upgrading just Cowlib, I'm not sure, some things might have changed
enough to cause issues when Cowlib 2.0 was released.
I would recommend upgrading Cowboy and Cowlib at the same time, Cowboy
releases tend to need a Cowlib update anyway.
Cowboy 2.6 will be released tomorrow, so I would wait for that as well.
In my experience updating a code base to use Cowboy 2 is fairly easy,
you mostly need to remove some unnecessary stuff or to convert lists of
key/values to maps. As always, test and measure.
