Hello!
I recently discovered the --warnings-as-errors flag and strongly prefer the workflow of being blocked by compiler warnings. Warnings in Elixir seem to be much more important (i.e. calls to undefined functions) than what I typically see as warnings in my experience with other languages (i.e. lint errors, unused variables).
I’m currently working through a Phoenix project but found that mix phx.server --warnings-as-errors was unrecognized. Is there a way to tell mix/Elixir to use --warnings-as-errors under the hood when running phx.server?
Thank you for your help!

Hello!
--warnings-as-errorsis a flag formix compile.What do you expect from

Thanks for the responses!
Adding
elixirc_options: [warnings_as_errors: true]to myprojectinmix.exsachieved my goal! Now warnings display as errors when I am working in Phoenix, which works great with live reload. If I start the server with an error, it fails to run - which is fine with me.The only down side is that the warning itself is not printed to the browser - it just shows a generic
compilation errorscreen. The console in which I ranmix phx.serverstill displays the rest of the information, at least. I assume there is a configuration setting somewhere to output those warnings to the web display, but for now I am happy.Thank you again!
