Composer Configuration

{
    "repositories": {
        "nova-menus": {
            "type": "path",
            "url": "packages/nova-menus"
        },
        "nova-medialibrary-field": {
            "type": "path",
            "url": "packages/nova-medialibrary-bounding-box-field"
        }
    },
    "require": {
        "pcrcard/nova-menus": "@dev",
        "pcrcard/nova-medialibrary-bounding-box-field": "@dev"
    }
}

Package Development Patterns

1. Creating New Nova Field

PHP Field Class (src/Fields/MyField.php):

namespace Vendor\Package\Fields;

use Laravel\Nova\Fields\Field;

class MyField extends Field
{
    public $component = 'my-field';

    public function __construct($name, $attribute = null, callable $resolveCallback = null)
    {
        parent::__construct($name, $attribute, $resolveCallback);
    }

    // Custom methods for field configuration
    public function withConfig(array $config): self
    {
        return $this->withMeta(['config' => $config]);
    }
}

Vue Component Registration (resources/js/field.js):

import IndexField from './components/IndexField'
import DetailField from './components/DetailField'
import FormField from './components/FormField'

Nova.booting((app, store) => {
  app.component('index-my-field', IndexField)
  app.component('detail-my-field', DetailField)
  app.component('form-my-field', FormField)
})

Component Template (resources/js/components/FormField.vue):

<template>
  <DefaultField
    :field="field"
    :errors="errors"
    :show-help-text="showHelpText"
  >
    <template #field>
      <div class="my-field-wrapper">
        <!-- Your field UI -->
      </div>
    </template>
  </DefaultField>
</template>

<script>
import { DependentFormField, HandlesValidationErrors } from 'laravel-nova'

export default {
  mixins: [DependentFormField, HandlesValidationErrors],

  props: ['resourceName', 'resourceId', 'field'],

  methods: {
    fill(formData) {
      formData.append(this.field.attribute, this.value || '')
    }
  }
}
</script>

2. Webpack Configuration (Nova 5.x)

Standard webpack.mix.js for Nova Packages:

let mix = require('laravel-mix')

mix
  .setPublicPath('dist')
  .js('resources/js/field.js', 'js')
  .vue({ version: 3 })
  .css('resources/css/field.css', 'css')
  .webpackConfig({
    externals: {
      vue: 'Vue',
      'laravel-nova': 'LaravelNova',
      'laravel-nova-ui': 'LaravelNovaUi',
    },
    output: {
      uniqueName: 'vendor/package',
    },
  })
  .version()

Key Points:

setPublicPath('dist') - Output directory
vue({ version: 3 }) - Vue 3 for Nova 5.x
Externals - Don't bundle Vue/Nova (provided by Nova)
uniqueName - Prevents webpack conflicts
version() - Cache busting with mix-manifest.json

3. Service Provider Registration

namespace Vendor\Package;

use Laravel\Nova\Nova;
use Laravel\Nova\Events\ServingNova;
use Illuminate\Support\ServiceProvider;

class FieldServiceProvider extends ServiceProvider
{
    public function boot()
    {
        Nova::serving(function (ServingNova $event) {
            Nova::script('my-field', __DIR__.'/../dist/js/field.js');
            Nova::style('my-field', __DIR__.'/../dist/css/field.css');
        });
    }

    public function register()
    {
        //
    }
}

Alternative (Laravel Mix manifest):

public function boot()
{
    Nova::serving(function (ServingNova $event) {
        Nova::mix('my-field', __DIR__.'/../dist/mix-manifest.json');
    });
}

4. Package composer.json

{
    "name": "pcrcard/my-nova-field",
    "description": "My Nova field description",
    "keywords": ["laravel", "nova", "field"],
    "license": "MIT",
    "require": {
        "php": "^8.2",
        "laravel/nova": "^5.0"
    },
    "autoload": {
        "psr-4": {
            "Pcrcard\\MyNovaField\\": "src/"
        }
    },
    "extra": {
        "laravel": {
            "providers": [
                "Pcrcard\\MyNovaField\\FieldServiceProvider"
            ]
        }
    },
    "minimum-stability": "dev",
    "prefer-stable": true
}

Development Workflows

Package Development Workflow

Complete workflow for modifying a package:

# 1. Navigate to package directory
cd packages/nova-medialibrary-bounding-box-field/

# 2. Make code changes
# Edit src/Fields/BoundingBoxField.php
# Edit resources/js/components/FormField.vue

# 3. Build assets
npm run dev          # Development build (faster)
npm run prod         # Production build (minified)

# 4. Test in main app
cd ../..
composer update pcrcard/nova-medialibrary-bounding-box-field

# 5. Commit to package repo
cd packages/nova-medialibrary-bounding-box-field/
git add .
git commit -m "feat: Add new feature to bounding box editor"
git push origin master

# 6. Update main app (optional)
cd ../..
composer update pcrcard/nova-medialibrary-bounding-box-field

Creating New Forked Package

# 1. Fork upstream package on GitHub
# 2. Clone into packages/ directory
cd packages/
git clone https://github.com/hackur/new-package.git

# 3. Update composer.json namespace
cd new-package/
# Edit composer.json: Change namespace to "pcrcard/*"

# 4. Add to main app composer.json
cd ../..
# Add repository and require to composer.json

# 5. Install package
composer install

# 6. Update package management script
# Edit scripts/lib/packages.sh - add to get_forked_packages()

Best Practices

Git Workflow

✅ ALWAYS commit to package repo first, then main app
✅ Use semantic versioning tags (v1.0.0, v2.0.0)
✅ Keep package and app commits separate
✅ Reference package commits in app commit messages
✅ Push to fork remote (origin), not upstream

Asset Building

✅ Build in package directory (not main app)
✅ Use npm run prod for production builds
✅ COMMIT dist/ files to package repo (required for Nova)
❌ Never commit node_modules/
✅ Test builds locally before committing

Dependencies

✅ External packages in externals config (Vue, Nova, etc.)
❌ Don't bundle Nova or Vue in package assets
✅ Use @dev version constraint for local development
✅ Lock upstream versions in package.json

Symlinks

✅ Composer creates symlinks automatically
✅ vendor/pcrcard/* → packages/*
❌ Don't modify symlinks manually
✅ Rebuild symlinks: composer install

Troubleshooting

Package Changes Not Reflected

Symptom: Modified package code doesn't appear in Nova

Solution:

cd packages/<package>/
npm run dev                               # Rebuild assets
cd ../..
composer update pcrcard/<package>         # Update main app
php artisan nova:publish                  # Republish Nova assets
php artisan cache:clear                   # Clear cache

Webpack Errors (Cannot Find Module)

Symptom: Module not found: Error: Can't resolve 'laravel-nova'

Solution: Check externals configuration

// webpack.mix.js
.webpackConfig({
    externals: {
        vue: 'Vue',                         // ✅ Must be externalized
        'laravel-nova': 'LaravelNova',     // ✅ Must be externalized
        'laravel-nova-ui': 'LaravelNovaUi', // ✅ Must be externalized
    },
})

Vue Component Not Rendering

Symptom: Nova field shows blank or error in console

Solution:

Check component registration in field.js
Verify $component property matches registration name
Check browser console for errors
Verify Vue 3 syntax (Composition API vs Options API)

// ✅ CORRECT: Registration matches field $component
Nova.booting((app) => {
  app.component('index-my-field', IndexField)  // matches $component = 'my-field'
})

Symlink Broken

Symptom: vendor/pcrcard/<package> missing or broken

Solution:

rm -rf vendor/pcrcard/<package>
composer install                  # Recreates symlinks

Asset Build Fails

Symptom: npm run dev or npm run prod fails

Solution:

rm -rf node_modules/
rm package-lock.json
npm install
npm run dev

Package Not Found After Installation

Symptom: Composer can't find package

Solution: Verify composer.json configuration

{
    "repositories": {
        "my-package": {
            "type": "path",
            "url": "packages/my-package"  // ✅ Correct path
        }
    },
    "require": {
        "pcrcard/my-package": "@dev"      // ✅ Correct constraint
    }
}

Nova 5.x Specific Patterns

Vue 3 Component Structure

<script setup>
import { ref, computed } from 'vue'

const props = defineProps({
  resourceName: String,
  resourceId: [String, Number],
  field: Object,
})

const value = ref(props.field.value || '')

const fill = (formData) => {
  formData.append(props.field.attribute, value.value)
}

defineExpose({ fill })
</script>

Field Meta Data

// Pass data to Vue component
MyField::make('Name')
    ->withMeta([
        'config' => [
            'option1' => true,
            'option2' => 'value',
        ],
    ]);

Access in Vue:

// this.field.config (Options API)
// props.field.config (Composition API)

Nova Mixins (Options API)

import { DependentFormField, HandlesValidationErrors } from 'laravel-nova'

export default {
  mixins: [DependentFormField, HandlesValidationErrors],
  // ...
}
