Laravel event sourcing generator

Laravel event sourcing generator scaffolds complete domain structures for Spatie's Laravel Event Sourcing, providing a single Artisan command to generate events, projections, projectors, aggregates, reactors, actions, DTOs, notifications, and PHPUnit tests.

New to event sourcing? Check out Spatie's documentation to understand projections, aggregates, and reactors.

Using Claude Code? Install the companion claude-laravel-event-sourcing skill to scaffold domains conversationally.

Installation

Compatibility

| What | Version | |-----------------------------------------------------------------------------|-------------| | PHP | 8.3 / 8.4 | | Laravel | 10.x / 11.x | | Spatie's event sourcing | 7.x |

Install

composer require albertoarena/laravel-event-sourcing-generator

Quick Start

Generate a basic domain structure:

php artisan make:event-sourcing-domain Animal --domain=Animal

This creates a complete event-sourced domain with events, projections, projectors, and actions in app/Domain/Animal/Animal/.

For more advanced features, see the Usage section below.

What Gets Generated

Running the command creates this structure in your app/Domain/{DomainName}/{ModelName}/ directory:

Always Generated: - Actions/ - Create/Update/Delete action classes - DataTransferObjects/ - DTOs for model data - Events/ - Domain events (Created, Updated, Deleted) - Projections/ - Read model (Eloquent model) - Projectors/ - Event handlers that update projections

Optional (with flags): - Aggregates/ - Aggregate root (--aggregate=1, requires uuid primary key) - Reactors/ - Side-effect handlers (--reactor=1) - Notifications/ - Event notifications (--notifications=database,mail,slack,teams) - Notifications/Concerns/ - Shared notification traits - tests/Domain/{DomainName}/{ModelName}/ - PHPUnit tests (--unit-test)

With Failed Events (--failed-events=1): - Additional events: {Model}CreationFailed, {Model}UpdateFailed, {Model}DeletionFailed - Corresponding notifications if --notifications is also specified

Usage

php artisan make:event-sourcing-domain <model> [options]

Basic Options: - -d|--domain=<domain> - The name of the domain - --namespace=<namespace> - The namespace or root folder (default: "Domain") - --root=<root> - The name of the root folder (default: "app")

Migration Options: - -m|--migration=<migration> - Existing migration for the model (with or without timestamp prefix, or table name) - --migration-exclude=<pattern> - Migration pattern to exclude (supports regex)

Feature Flags: - -a|--aggregate=<0|1> - Generate aggregate (requires uuid primary key) - -r|--reactor=<0|1> - Generate reactor - -u|--unit-test - Generate PHPUnit tests - --failed-events=<0|1> - Generate failed event classes - --notifications=<types> - Generate notifications (database,mail,slack,teams, or no)

Model Configuration: - -p|--primary-key=<uuid|id> - Primary key type (default: uuid) - --indentation=<spaces> - Indentation spaces for generated code (default: 4)

Show help

php artisan help make:event-sourcing-domain

Basic usage

Documentation about basic usage

Generate a model with same name of the domain

php artisan make:event-sourcing-domain Animal \
  --domain=Animal

Generate a model with different domain

Read documentation with examples

php artisan make:event-sourcing-domain Tiger \
  --domain=Animal

Generate a model with different domain and namespace

Read documentation with examples

php artisan make:event-sourcing-domain Tiger \
  --domain=Animal \
  --namespace=CustomDomain 

Generate a model from existing migration

Read documentation with examples

php artisan make:event-sourcing-domain Animal \
  --migration=create_animal_table \
  --unit-test

Generate a model from existing migration using pattern and exclude specific one

Read documentation with examples

php artisan make:event-sourcing-domain Animal \
  --migration=animal \
  --migration-exclude=drop_last_column_from_animals \
  --unit-test

Generate a model from existing migration using pattern and exclude using regex

Read documentation with examples

php artisan make:event-sourcing-domain Animal \
  --migration=animal \
  --migration-exclude="/drop_.*_from_animals/" \
  --unit-test

Generate a model from existing migration with failed events and notifications

php artisan make:event-sourcing-domain Animal \
  --migration=create_animal_table \
  --failed-events=1 \
  --notifications=database,mail,slack

Domain and namespace

Read documentation about directory structure

Specify the name of the domain

Read documentation with examples

php artisan make:event-sourcing-domain Animal --domain=Tiger
php artisan make:event-sourcing-domain Animal --domain=Lion

Specify the namespace

Read documentation with examples

php artisan make:event-sourcing-domain Tiger --namespace=MyDomain --domain=Animal

Advanced usage

Set primary key

Read documentation with examples

Default primary key is uuid. That will work with Aggregate class.

It is possible to use id as primary key:

php artisan make:event-sourcing-domain Animal --primary-key=id

When importing migrations, primary key will be automatically loaded from file.

Generate PHPUnit tests

Read documentation with examples

php artisan make:event-sourcing-domain Animal --unit-test

Generate aggregates

Read documentation with examples

php artisan make:event-sourcing-domain Animal --aggregate=1

This is available only for models using uuid as primary key.

Generate reactors

Read documentation with examples

php artisan make:event-sourcing-domain Animal --reactor=1

Generate failed events

Read documentation with examples

php artisan make:event-sourcing-domain Animal --failed-events=1

Generate notifications

Read documentation with examples

php artisan make:event-sourcing-domain Animal --notifications=<NOTIFICATIONS>

Specify indentation

Read documentation with examples

php artisan make:event-sourcing-domain Animal --indentation=2

Specify the path of root folder

Read documentation with examples

php artisan make:event-sourcing-domain Animal --root=src
