Fellow devs - if you have a "repository"-like object that only has a single implementation do you do this? If so - why?pic.twitter.com/GRogvFc7qu

The only harm I can see in creating the interface later is that it'd mean a change to a bunch of unrelated code. You'd have to update other places to rely on the new interface instead of the class. I guess it's planning for a possibly complex future or thinking YAGNI.
I have never had to do that.
And even if you did have to do it, what's the problem of extracting an interface *at that point* rather than before.I really just think "YAGNI" when I see this. I've started tending to favour overt simplicity from the beginning until I absolutely need the extra complexity.
