Introduction to the Apex Common Library

What is the Apex Common Library?

The Apex Common Library is an open source library originally created by Andy Fawcett when he was the CTO of FinancialForce and currently upkept by many community members, but most notably John Daniel. Aside from its origins and the fflib_ in the class names, it is no longer linked to FinancialForce in any way.

The library was originally created because implementing the Separation of Concerns Design Principle is difficult no matter what tech stack you're working in. For Salesforce, the Apex Common Library was built to simplify the process of implementing Separation of Concerns as well as assist in managing DML transactions and enforcing coding and security best practices. If you want an exceptionally clean, understandable and flexible code base, the Apex Common library will greatly assist you in those endeavours.
