Some architecture-related commands for Laravel developers

PHP 8.1+ · Laravel 10 / 11 · install as --dev

Generate PlantUML class diagrams from your Laravel namespaces.

LarchiClass inspects your PHP classes produces a .puml file ready to render with PlantUML. The larchi:class command covers all PHP types (classes, interfaces, traits, enums), while larchi:model enriches the diagram with Eloquent properties and model relationships.

Installation

composer require quatrebarbes/larchiclass --dev

Commands

Command	Description
larchi:caller	Analyze all the function callers leading to a method & shdescribe the flow into a diagram.
larchi:class	General-purpose diagram — classes, interfaces, traits, enums. Dependencies resolved from type hints.
larchi:model	Eloquent diagram — $fillable, $casts, $hidden properties and relationships (hasMany, belongsTo, morphTo…).

Examples of using larchi:caller

# Default output: larchi-caller.puml
php artisan larchi:class "App\Domain\Billing::readInvoice"

# Custom output file
php artisan larchi:class "App\Domain\Billing::readInvoice" --output="docs/billing-read-invoice.puml"

Examples of using larchi:class

# Default namespace (App), output: larchi-class.puml
php artisan larchi:class

# Custom namespace
php artisan larchi:class --namespace="App\Domain\Billing"

# Custom output file
php artisan larchi:class --output="docs/billing.puml"

# Include parents and dependencies outside the namespace
php artisan larchi:class --namespace="App\Http\Controllers" --with-related

# Include everything, vendor classes included
php artisan larchi:class --with-related --with-vendors

Example of using larchi:model

# Default namespace (App\Models), output: larchi-model.puml
php artisan larchi:model

# Specific subdomain
php artisan larchi:model --namespace="App\Models\Billing" --output="docs/billing-models.puml"

# Include Eloquent parent classes
php artisan larchi:model --with-related --with-vendors

The .puml file can be rendered with PlantUML, the VS Code PlantUML extension, or any compatible tool. The diagram is left-to-right by default.

What the diagram includes

larchi:caller

• All functions/methods that call the target method directly or not
• The complete chain of callers up to http routes & artisan commands

larchi:class

• All classes, interfaces, traits, and enums in the target namespace
• Properties with type, visibility (+ # -), and {static} modifier
• Methods with visibility, {abstract}, and {static} modifiers
• Inheritance arrows (<|--), implementation arrows (<|..), trait usage (<..), and dependency arrows (..>)
• Stubs for classes referenced outside the scope (with --with-related)

larchi:model (everything from larchi:class, plus…)

• Properties sourced from $fillable, $hidden, $casts, $dates, and $appends
• Computed visibility: a field present in both $fillable and $hidden is rendered as private
• Types resolved from $casts: decimal:2 → decimal, AsCollection::class → AsCollection
• Eloquent relationships: hasOne, hasMany, belongsTo, belongsToMany, hasManyThrough, hasOneThrough, morphOne, morphMany, morphTo, morphToMany, morphedByMany
• Automatic cardinality ("1" -- "*", "*" -- "*", etc.)
• Reciprocal pairs merged into a single arrow annotated with both method names
• Stereotypes <<model>>, <<vendor>>, <<trait>>
