In the world of software management there exists a dread place called “dependency hell.” The bigger your system grows and the more packages you integrate into your software, the more likely you are to find yourself, one day, in this pit of despair.

“Always avoid external dependencies you cannot control. Direcly linking to a resource in someone else’s code repository is a perfect example of an external dependency that can easily be, and should be, avoided. The moral of the story is: ‘never never never link to a resource inside a source code repository’.”
