Easily build Eloquent queries from API requests using Alchemist Restful API.

Description

This is a package that helps you integrate Alchemist Restful API with Laravel Eloquent. for more information about concepts and usage of Alchemist Restful API, please refer to the Alchemist Restful API documentation

Installation

composer require nvmcommunity/laravel-eloquent-api

Basic usage

Step 1: Define the API class

use Nvmcommunity\Alchemist\RestfulApi\Common\Exceptions\AlchemistRestfulApiException;
use Nvmcommunity\Alchemist\RestfulApi\Common\Integrations\AlchemistQueryable;
use Nvmcommunity\Alchemist\RestfulApi\FieldSelector\Handlers\FieldSelector;
use Nvmcommunity\Alchemist\RestfulApi\ResourceFilter\Handlers\ResourceFilter;
use Nvmcommunity\Alchemist\RestfulApi\ResourceFilter\Objects\FilteringRules;
use Nvmcommunity\Alchemist\RestfulApi\ResourcePaginations\OffsetPaginator\Handlers\ResourceOffsetPaginator;
use Nvmcommunity\Alchemist\RestfulApi\ResourceSearch\Handlers\ResourceSearch;
use Nvmcommunity\Alchemist\RestfulApi\ResourceSort\Handlers\ResourceSort;

class UserApiQuery extends AlchemistQueryable
{
    /**
     * @param FieldSelector $fieldSelector
     * @return void
     */
    public static function fieldSelector(FieldSelector $fieldSelector): void
    {
        $fieldSelector->defineFieldStructure([
            'id', 'name', 'email', 'created_at'
        ])
        ->defineDefaultFields(['id']);
    }

    /**
     * @param ResourceFilter $resourceFilter
     * @return void
     */
    public static function resourceFilter(ResourceFilter $resourceFilter): void
    {
        $resourceFilter->defineFilteringRules([
            FilteringRules::String('id', ['eq']),
            FilteringRules::String('name', ['eq', 'contains']),
            FilteringRules::String('email', ['eq', 'contains']),
            FilteringRules::Datetime('created_at', ['eq', 'gte', 'lte', 'between']),
        ]);
    }

    /**
     * @param ResourceOffsetPaginator $resourceOffsetPaginator
     * @return void
     */
    public static function resourceOffsetPaginator(ResourceOffsetPaginator $resourceOffsetPaginator): void
    {
        $resourceOffsetPaginator->defineDefaultLimit(10)
            ->defineMaxLimit(1000);
    }

    /**
     * @param ResourceSearch $resourceSearch
     * @return void
     */
    public static function resourceSearch(ResourceSearch $resourceSearch): void
    {
        $resourceSearch->defineSearchCondition('name');
    }

    /**
     * @param ResourceSort $resourceSort
     * @return void
     * @throws AlchemistRestfulApiException
     */
    public static function resourceSort(ResourceSort $resourceSort): void
    {
        $resourceSort->defineDefaultSort('id')
            ->defineDefaultDirection('desc')
            ->defineSortableFields(['id', 'name']);
    }
}

Step 2: Validate & respond to the request

Make sure to validate the input parameters passed in from the request input by using the $eloquentBuilder->validate() method before executing the query and responding to the request.

use App\Models\User;
use Illuminate\Http\JsonResponse;
use Illuminate\Http\Request;
use Nvmcommunity\Alchemist\RestfulApi\Common\Exceptions\AlchemistRestfulApiException;
use Nvmcommunity\EloquentApi\EloquentBuilder;

class UserController extends Controller
{
    /**
     * @param Request $request
     * @param JsonResponse $response
     * @return JsonResponse
     * @throws AlchemistRestfulApiException
     */
    public function index(Request $request, JsonResponse $response): JsonResponse
    {
        $eloquentBuilder = EloquentBuilder::for(User::class, UserApiQuery::class, $request->input());

        // Validate the input parameters
        if (! $eloquentBuilder->validate($e)->passes()) {
            return $response->setData($e->getErrors())->setStatusCode(400);
        }

        // It's safe to execute the query now.
        // Return the result as JSON
        return $response->setData($eloquentBuilder->getBuilder()->get());
    }
}
