  • Use abstraction to hide sub-routines and keep functional code as simple as possible.

  • Use automated testing to make sure new code doesn't break old features.

In addition to your application's growing complexity, your application will suffer from scaling pains as you gain more users. As your user base increases, so does your server load, disk space requirements, database hits, and Twitter API calls. You must address these scaling issues first, or your application is at risk of crashing.

This chapter is here to warn you of potential growing pains and point you in the direction of potential solutions.
