Build only when files change

Does anyone have any bright ideas on how to have dfx build xxxxxx detect if files have changed? Or do you have a good strategy for detecting this in bash? I’m sitting around waiting quite a bit these days and much of the time I’m waiting on repeat builds.

I think it comes down to whatever commands dfx build issues having support for this.

I use nix, and one benefit of that is only rebuilding what is necessary.

My workflow for dev vs production builds is different though so there’s still room for improvement.

Other than looking up the docs, any pointers/resources/samples of how to do this with nix that you’d recommend?

There’s a learning curve :sweat_smile:

Maybe start with Nix Pills: Chapter 6. Our First Derivation and look at previous chapters if necessary.
