Extending application logic with platform extensibility features

So far in this chapter, we have discussed the ways in which Developer X explicitly calls APIs from processes or tasks they are implementing by using the standard platform APIs or application APIs you build and include in your package. We will now shift to understanding how Developer X can extend features of your application as the user runs processes and performs tasks within your application UI, via the code or configuration Developer X creates, and extend the application logic after the package has been installed.

Regardless of if you see this being required, the platform provides the possibility for this type of extensibility, and you should make sure you anticipate it. Here are some other platform features that can help ensure that your application’s functionality is open to being extended...
