EspoCRM Development
Overview
EspoCRM is a metadata-driven CRM platform where configuration lives in JSON files, business logic belongs in Services, and data access happens through ORM EntityManager. This skill enforces architectural patterns to prevent common mistakes like passing Container dependencies, bypassing the service layer, or implementing business logic in hooks.
When to Use This Skill
Activate when developing custom EspoCRM modules, entities, relationships, hooks, services, API endpoints, or integrations. Use especially when: working with ORM (EntityManager required), implementing business logic (belongs in Services), creating hooks (use interfaces), modifying metadata (requires cache rebuild), or building custom field types.
The Iron Law
BUSINESS LOGIC IN SERVICES, NOT HOOKS | DATA ACCESS VIA ENTITYMANAGER, NEVER DIRECT PDO | NEVER PASS CONTAINER AS DEPENDENCY
If you're accessing Container directly or writing business logic in hooks, you're violating architecture.
