There is not much explanation needed on how to code. But there always comes the time where you get stuck. We made pretty good experience with the following tools in such situations:
prypry-remotepry-rescuebyebug
If you’re used to inserting debugging breakpoints into your code (e.g., with Pry or Byebug), forego may throw you for a loop — since it manages the output of multiple processes, your debugger prompt will appear briefly on the screen and then fly past it, along with the STDOUT of any other processes forego is overseeing.
Instead, use a remote debugger like pry-remote.
