The State of Rules for D9+
(and intro to ECA)

What is Rules?

Drupal module for triggering functionality
Think of it like hooks (except with a GUI)
- Or event subscribers
Events
- Something in system that triggers an action to potentially run
Conditions
- Validate that action is fit to run
Action
- Perform some task

Why?

Create pluggable systems
- Actions not hardcoded in codebase to get triggered on a specific event
More resilient actions
- Actions can be more generalized
Has a GUI
Is exportable so can be in your version control system

Why not?

Building a specialized app
Slower
More dependencies
Does not mean you won't require code

Examples

Content moderation
- Mark content as draft when it enters system
- Unpublish
- Email content admins
User registration / signs in for first time
- Invite them to slack

Look at Rules

For D7 and D9

Current state of Rules

Kinda unsupported
Business Rules, TR_Rules (trimmed rules) exist but also minimally unsupported
Limited functionality compared to D7

ECA Module

https://www.drupal.org/project/eca
Event - Condition - Action
Fairly large ecosystem
- Integrations with webform, groups, commerce
Not as nice GUI
- External projects for improved workflows
Well supported
- https://ecaguide.org/
