That's the lack of design of a library, not really necessarily the size. You could easily have one entry point class with a bunch of ready to use functions and start your docs off there. Otherwise, you're just punting the discovery problem up a level. There's also a benefit in having multiple things in a module. You could make your code generic over the type of hash being used for instance. As far as node, you could easily export 20 different hash functions for use, instead of a dedicated sha1 package. Then getting yet another when you want hmac. The downside is nontrivial. In a repeatable build environment it can add tens of minutes of delays to a build as these tens of thousands of files aren't free. (And that was on a VM by one of the big providers, with top notch bandwidth.) Just even doing a local copy of so many files can take a while.
