README

Laravel package for downloading and seeding Indonesian address data (provinces, regencies, districts, villages) with postal codes from the official Pos Indonesia website.

Features

• Auto-download postcode data from Pos Indonesia
• Hierarchical data parsing: Province → Regency → District → Village
• Ready-to-use database seeders
• Migration files included
• Configurable and extendable Eloquent models
• Supports Laravel 11, 12, and 13

Installation

composer require ajangsupardi/laravel-postcode-id

Publish Configuration (optional)

php artisan vendor:publish --tag=postcode-config

Publish Migrations (optional)

php artisan vendor:publish --tag=postcode-migrations

Note: Migrations are automatically loaded by the service provider, so publishing is only needed if you want to modify the table structure.

Usage

1. Download Postcode Data

php artisan postcode:download

This command will download all postcode data from Pos Indonesia and save it as a CSV file.

2. Run the Seeder

php artisan db:seed --class=Ajangsupardi\PostcodeId\Database\Seeders\PostcodeSeeder

Or add it to your DatabaseSeeder.php:

use Ajangsupardi\PostcodeId\Database\Seeders\PostcodeSeeder;

public function run(): void
{
    $this->call([
        PostcodeSeeder::class,
    ]);
}

3. Auto-download & Seed

If you want to combine download and seed in a single step, you can call the download command before the seeder:

use Illuminate\Support\Facades\Artisan;

$storagePath = config('postcode.storage_path');
if (! file_exists($storagePath.'/kodepos.csv')) {
    Artisan::call('postcode:download');
}

Database Tables

This package creates 4 tables:

Configuration

Edit config/postcode.php:

return [
    // CSV file storage path
    'storage_path' => storage_path('app/postcode'),

    // Database table prefix (null = no prefix)
    'table_prefix' => null,

    // Custom models
    'models' => [
        'province' => Ajangsupardi\PostcodeId\Models\Province::class,
        'regency'  => Ajangsupardi\PostcodeId\Models\Regency::class,
        'district' => Ajangsupardi\PostcodeId\Models\District::class,
        'village'  => Ajangsupardi\PostcodeId\Models\Village::class,
    ],

    // HTTP client settings
    'http' => [
        'timeout' => 60,
        'connect_timeout' => 10,
        'retry' => 3,
        'retry_delay' => 1000,
        'user_agent' => 'Mozilla/5.0 (compatible; LaravelPostcodeId/1.0)',
    ],
];

Custom Models

You can extend the default models to add columns or relationships:

namespace App\Models;

use Ajangsupardi\PostcodeId\Models\Province as BaseProvince;

class Province extends BaseProvince
{
    protected $fillable = ['name', 'code', 'your_custom_field'];

    // Add custom relationships or methods
}

Then update the configuration:

'models' => [
    'province' => App\Models\Province::class,
],

Table Prefix

If you want to use a prefix for your tables:

'table_prefix' => 'postcode_',

This will create tables: postcode_provinces, postcode_regencies, postcode_districts, postcode_villages.

Example Queries

use Ajangsupardi\PostcodeId\Models\Province;
use Ajangsupardi\PostcodeId\Models\Village;

// Get all provinces
$provinces = Province::all();

// Get regencies in East Java
$regencies = Province::where('name', 'Jawa Timur')
    ->first()
    ->regencies;

// Find a village by postal code
$village = Village::where('postal_code', '60111')->first();

// Get full address hierarchy from village to province
$village = Village::with('district.regency.province')
    ->where('postal_code', '60111')
    ->first();
