spago bundle-app has a handy option that skips a bulid: --no-build. It would be great if this option was supported in spago run as well.
Usecase: when running purescript-written backend on a machine with which sources were shared via NFS, spago's attempt to rebuild sources slows down start up time considerably. I found via bpftrace that it's possible to "run" manually by executing node .spago/run.js.
Measuring running time for the code with its main replaced to main = pure unit shows:
