Why It Matters
AT4DX takes fflib’s separation-of-concern patterns and adds the plumbing you need for truly modular Salesforce architectures. Its dependency injection framework lets you swap implementations at configuration time — critical for ISVs and teams building extensible packages.
The platform event consumer pattern is particularly useful for architects designing event-driven systems. Instead of manually wiring up trigger handlers for platform events, AT4DX gives you a declarative binding mechanism.
Alternatives
- fflib Apex Common — the foundation AT4DX extends
- Custom DI frameworks — possible, but AT4DX is battle-tested
