Q: I want to create custom db effects that are composable. Is there any prior art for how to do this?

I want this because I want them de-coupled (compared to just composing fns which couples via a require)

but they need to compose e.g. http response handler calls a de-coupled util db effect and adds its own custom db transforms.

One idea would be to allow these effects to accept a seq of “decorator” fns along with its args

but I’m curious about other designs

the perfect solution would allow composition of n db effects and some custom db transforms in an event handler output map
