Chapter 4 outlined the "advanced basics" of creating custom pipelines and pipeline components. You should now have the tools that you will need to create well-structured and professional-looking pipeline components. Now that you have learned the internals of how pipelines and pipeline components work, you'll put your new knowledge into practice. This chapter will explore some of the nuances of pipeline component development as well as give you some best practices for creating and implementing them. We will show you some examples of common problems that pipeline components can solve, along with some advanced implementations of cryptography, compression, and decoding.
