depends on what you need. People have pointed you towards JET.jl for static analysis that understands typing system. And I have suggested Revise.jl so you don’t have to keep re-launching your program.
How do you kill the existing webserver / restart a new webserver on file change with Revise.jl ?
I think @jling is proposing that you don’t have to: unlike Scala, Julia is capable of updating code in the middle of a running session. See Developer reference · Revise.jl and consider checking out Genie.jl, which I believe already implements all this for you.
