Possible to rewire anonymous function

Is it possible to rewire an anonymous function that is returned as module.exports? For example, if I want to have a dep.js file with the following content:

module.exports = function(inp) { blah }

How can I rewire it to change the module.exports (__set__ it) to another function? (it is useful to me, because I am about to stub it for testing another code file that require-s it, but anyway don’t care about why that would be useful to me)

Anyway, thanks for your kind help. I found one way to correct my issue: get all those to-be-mocked requires outside of the function in files using it, so now I can rewire them anyways without rewiring the original module.exports default function.

Sorry, I miss what you are trying to do. If you could include a minimal example of what doesn’t work, I could take a look. Or maybe it’s just over my head 😉
