Expressive

Appearance

Configuration ​

Introduction ​

Expressive stores its application-level options in config/expressive.php. You may publish this file with the expressive-config tag:

shell
php artisan vendor:publish --tag="expressive-config"

The default configuration is intentionally small. It controls implicit class lookup, conversion diagnostics, serialization key casing, and generator defaults.

Expressive namespace ​

The namespace option defines where Expressive classes are generated and where implicit mapping looks for them:

php
'namespace' => 'App\\Expressive',

With the default value, App\Models\User maps to App\Expressive\User. If your application keeps data objects in another namespace, update this value before generating classes:

php
'namespace' => 'App\\Data',

You may still override the mapping for a single model or Expressive class with attributes. Use #[Expressive] on a model when the model should resolve a specific Expressive class, or use #[Model] on an Expressive class when it should map back to a specific Eloquent model.

Class suffixes ​

The suffix option appends a suffix to generated class names and implicit lookups:

php
'suffix' => 'Expressive',

With this configuration, App\Models\User maps to App\Expressive\UserExpressive. The same suffix is used when resolving an Expressive object back to its model.

Keep the suffix empty when your Expressive classes should use the same base name as the mapped Eloquent model:

php
'suffix' => '',

Diagnostics ​

Expressive uses Eloquent's fillable rules when converting an Expressive object back into a model. By default, mapped properties that are not fillable are ignored in the same conservative spirit as normal mass-assignment behavior:

php
'diagnostics' => [
    'throw_on_unfillable' => false,
],

You may enable diagnostics while adopting Expressive in an existing application:

php
'diagnostics' => [
    'throw_on_unfillable' => true,
],

When enabled, Expressive throws before calling fill() if a non-virtual, non-relationship property maps to an attribute the model will not fill. Virtual properties and relationship properties are excluded from this check.

Serialization casing ​

Expressive serializes public property names by default:

php
'serialization' => [
    'case' => 'preserve',
],

For example, an emailVerifiedAt property serializes as emailVerifiedAt. If your API responses should use snake-case keys, set the option to snake:

php
'serialization' => [
    'case' => 'snake',
],

Visibility filtering still uses the mapped Eloquent key. A property mapped to remember_token is filtered by the model's hidden or visible rules for remember_token, even when the serialized property name would be rememberKey.

Generator defaults ​

The generator options define the defaults used by make:expressive when a matching CLI flag is not passed:

php
'generator' => [
    'with_attributes' => true,
    'with_relationships' => true,
    'exclude_hidden' => false,
    'hint_morph_map' => false,
],

Explicit command options always win for a single run. For example, --without-relationships disables relationship generation even when with_relationships is true in the config file.
