README

svk-digital/laravel-currency is an extensible Laravel package for working with fiat and crypto currency exchange rates. Out of the box it ships with adapters for the Central Bank of Russia DailyInfo web-service, CurrencyFreaks API, and ExchangeRateHost API, but you can plug in any provider via configuration or custom adapters.

Requirements

• PHP ^8.1
• Laravel 9.x, 10.x, 11.x or 12.x

Quick Start

use DateTimeImmutable;
use SvkDigital\Currency\Contracts\CurrencyServiceContract;
use SvkDigital\Currency\Facades\Currency;
use SvkDigital\Currency\ValueObjects\FiatCurrency;

final class RatesController
{
    public function __construct(private CurrencyServiceContract $currencyService) {}

    public function __invoke()
    {
        $date = new DateTimeImmutable('2024-11-30');

        // Via dependency injection
        $rate = $this->currencyService
            ->rate()
            ->base(new FiatCurrency('RUB'))
            ->quote(new FiatCurrency('USD'))
            ->date($date)
            ->get();

        // Or via facade
        $rate = Currency::rate()
            ->base(new FiatCurrency('RUB'))
            ->quote(new FiatCurrency('USD'))
            ->date($date)
            ->get();
    }
}

Installation

composer require svk-digital/laravel-currency

The service provider and facade are auto-discovered by Laravel. Publish the configuration:

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

For advanced usage, you can also publish and customize the service provider:

php artisan vendor:publish --tag=currency-provider

Documentation

Full documentation is available in the docs/ directory:

• Getting Started - Installation and basic usage
• Configuration - Package configuration options
• Built-in Adapters - Available adapters (CBR, CurrencyFreaks, ExchangeRateHost)
• Testing - Test your code with fake exchange rates
• Custom Adapters - Create your own adapter and override provider selection

Features

• ✅ Multiple built-in adapters (CBR, CurrencyFreaks, ExchangeRateHost)
• ✅ Support for fiat currencies via ISO-4217 value objects
• ✅ Crypto currency support (via custom adapters)
• ✅ Automatic caching with configurable TTL
• ✅ Custom adapter support
• ✅ Dynamic provider selection
• ✅ Comprehensive error handling
• ✅ Multiple quote currencies in a single request

Built-in Adapters

CBR Adapter

• Central Bank of Russia SOAP service
• RUB base currency only
• Historical rates support

CurrencyFreaks Adapter

• REST API integration
• Any base currency support
• API key required

ExchangeRateHost Adapter

• REST API integration
• Any base currency support
• Optional access key

See Built-in Adapters for detailed information.

Custom Adapters

You can create custom adapters to integrate with any currency provider. The package also allows you to override the service provider to implement dynamic provider selection logic without modifying configuration files.

See Custom Adapters Guide for complete instructions.

Testing

The package provides a fake() method on the Currency facade that allows you to mock exchange rates in your tests without making real API calls, similar to Laravel's Http::fake().

use DateTimeImmutable;
use SvkDigital\Currency\Facades\Currency;
use SvkDigital\Currency\ValueObjects\FiatCurrency;

// In your test setup
Currency::fake()
    ->setRateValue(
        new FiatCurrency('RUB'),
        new FiatCurrency('USD'),
        new DateTimeImmutable('2024-01-01'),
        90.5
    );

// Now your code will use the fake adapter
$rate = Currency::rate()
    ->base(new FiatCurrency('RUB'))
    ->quote(new FiatCurrency('USD'))
    ->date(new DateTimeImmutable('2024-01-01'))
    ->get();
