Laravel-Exchanger

A Laravel currency converter library that uses florianv/exchanger.

Installation

composer require juanparati/laravel-exchanger

Facade registration (optional):

'aliases' => [
    ...
    'CurrencyExchanger' => \Juanparati\LaravelExchanger\Facades\ExchangerConverterFacade,
    ...
]

Configuration

Publish configuration file:

artisan vendor:publish --provider="Juanparati\LaravelExchanger\Providers\ExchangerServiceProvider"

The configuration contains a list of services, check the florianv/exchanger documentation in order to know the description and characteristics of each service.

It's important to provide a valid cache time (in seconds) in order to avoid duplicate requests.

Usage

Get the currency rate

$rate = CurrencyExchanger::getRate('eur', 'pln'); // Return Exchanger\ExchangeRate
$rate->getValue();                                // Returns rate as float
$rate->getDate()->format('Y-m-d')                 // Returns exchange date

// Historical rate
CurrencyExchanger::getRate('nok', 'sek', now()->subDays(10));

Convert currency

CurrencyExchanger::convert('ron', 'dkk', 10); // Convert 10 RON to DKK and return as float

// Historical conversion rate 
CurrencyExchanger::convert('ron', 'dkk', 10, now()->subDays(5));

// Obtain the last rate (Exchanger\ExchangeRate) for the previous currency conversion
CurrencyExchanger::getLastExchangeRateResult();

Cache state

Is sometimes convenient to disable the cache in order of force to request the most recent rate or conversion. In order to achieve that is possible to disable temporally the cache:

CurrencyExchanger::setCacheStatus(false); // Cache disabled
CurrencyExchanger::setCacheStatus(true);  // Cache enabled

Remember that cache is always enabled by default when the configuration key "cache_time" has a valid integer.

Attach/Detach services on-demand

It's possible to attach and detach services on demand:

// Detach service
CurrencyExchanger::detach(\Exchanger\Service\Cryptonator::class);

// Attach service
CurrencyExchanger::attach(\Exchanger\Service\Cryptonator::class);

By default all the services registered into the configuration are attached by default.

Execute custom queries

Because this library works as a wrapper for florianv/exchanger it's possible to execute custom queries passing the build query to the "executeQuery" method.

...
CurrencyExchanger::executeQuery($query->build);
