require-maybe
Optionally require a module, optionally falling back to others.
- returns
undefinedif the optional module(s) can't be found - without throwing an exception
- can attempt to load alternative modules
- works with all paths (unlike similar modules)
This can be useful for libraries that want to use certain features when the optional modules are installed, without pulling in additional dependencies.
