EloquentHttpAdapter

EloquentHttpAdapter is a Laravel package that provides an alternative to calebporzio/sushi. It allows you to work with RESTful API data using an Eloquent-like syntax.

This package was originally developed to integrate Filament with APIs, making it a convenient tool for admin panels. However, thanks to its flexibility, it can also be used for any task requiring API integration with an Eloquent-like interface.

---

Installation

Install the package via Composer:

composer require iafilin/eloquenthttpadapter

---

Usage

Setting Up a Model

To enable API integration, use the InteractsWithHttp trait and define a custom httpClient method to configure the HTTP client:

namespace App\Models;

use Iafilin\EloquentHttpAdapter\InteractsWithHttp;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Http\Client\PendingRequest;

class Purchase extends Model
{
    use InteractsWithHttp;

    /**
     * Configure the HTTP client with the API endpoint.
     */
    private static function httpClient(): PendingRequest
    {
        return \Http::baseUrl('/api/admin/purchases');
    }
}

Registering a Fetch Parameters Resolver

You can define the logic for building HTTP query parameters using the registerFetchParamsResolver method. This allows dynamic configuration of pagination, filtering, and sorting parameters.

Additionally, within the resolver, you have access to the getQuery() object, which lets you retrieve Eloquent wheres conditions and use them to generate HTTP parameters.

Example setup:

class Purchase extends Model
{
    use InteractsWithHttp;

    protected static function boot()
    {
        parent::boot();

        static::registerFetchParamsResolver(function () {
            $params = [
                'page' => request()->query('page', 1),
                'per_page' => request()->query('per_page', 10),
            ];

            // Parse `wheres` from the query object
            foreach ($this->getQuery()->wheres as $where) {
                $params["filter[{$where['column']}"] = $where['value'];
            }

            return $params;
        });
    }
}

API Requirements

To ensure compatibility with the package, your API should follow these conventions:

1. Standard REST endpoints:

   • POST /api/resource — Create records.
   • GET /api/resource — Fetch records (paginated or full list).
   • GET /api/resource/{id} — Fetch a single record.
   • PUT /api/resource/{id} — Update a record.
   • DELETE /api/resource/{id} — Delete a record.

2. Response Structure:

   • Lists: Should include data, total, per_page, and current_page.
   • Single Record: Should return attributes directly without nesting.

Example paginated response:

{
    "data": [
        { "id": 1, "name": "Item 1" },
        { "id": 2, "name": "Item 2" }
    ],
    "total": 50,
    "per_page": 10,
    "current_page": 1
}

3. Pagination:

   • Support for page and per_page query parameters.

4. Filters and Sorting:

   • Filters: filter[column]=value.
   • Sorting: sort=column for ascending and sort=-column for descending.

---

CRUD Operations

Once your model is set up, you can use standard Eloquent methods to interact with your API:

Create a Record

$purchase = Purchase::create(['name' => 'New Item']);

Read Records

$purchases = Purchase::all(); // Fetch all records
$purchases = Purchase::paginate(10); // Paginate results

Update a Record

$purchase = Purchase::find(1);
$purchase->update(['name' => 'Updated Name']);

Delete a Record

$purchase = Purchase::find(1);
$purchase->delete();

---

Customizing HTTP Requests

You can fully customize HTTP request behavior by overriding the httpClient method in your model. For example, adding headers or specific configurations:

private static function httpClient(): PendingRequest
{
    return \Http::baseUrl('/api/admin/purchases')
                ->withHeaders(['Authorization' => 'Bearer token']);
}

Customizing API Fetch Parameters with registerFetchParamsResolver

The registerFetchParamsResolver method allows you to customize the HTTP query parameters sent to your API for fetching data. It provides a powerful way to dynamically build parameters like pagination, filters, and sorting based on the current Eloquent query or incoming user requests.

With access to the Eloquent query object ($this->getQuery()), you can parse wheres, orders, and other query conditions, transforming them into HTTP parameters compatible with your API.

Key Benefits:

• Dynamic configuration: Automatically adapt HTTP query parameters to match user input or specific query requirements.
• Seamless integration: Utilize existing Eloquent query methods while maintaining API compatibility.
• Support for complex queries: Build filters, pagination, and sorting logic based on both application and API needs.

Example Usage:

class Purchase extends Model
{
    use InteractsWithHttp;

    protected static function boot()
    {
        parent::boot();

        static::registerFetchParamsResolver(function () {
            $params = [
                'page' => request()->query('page', 1),
                'per_page' => request()->query('per_page', 10),
            ];

            // Parse where conditions from the query object
            foreach ($this->getQuery()->wheres as $where) {
                $params["filter[{$where['column']}"]"] = $where['value'];
            }

            return $params;
        });
    }
}

This makes it easy to dynamically adapt HTTP query parameters based on user input or predefined conditions in your Laravel application.

Error Handling

The package automatically logs errors during API interactions and returns null in case of failure. This ensures graceful handling of API downtime or errors without throwing exceptions.
