README

Provide the minimum functionality to get rate and perform currency amount conversion (using php math).

Install

To install run:

composer require grynchuk/currency 

Configuration

You may provide a configuration with available currencies that are used to get rates. Do do this you will need to add yaml config and pass it to Currency\DataProvider\CurrencyConfigDataProvider. This yaml config should looks like this:

currency:
  items:
    - { code: !php/enum Currency\Enum\Code::USD, precision: 2, description: 'United States Dollar'}

By default this configuration contain only three currency USD EUR PLN.

As for now no bridge to Symfony is provided (may be I`ll implement it later), so you need to do it by your self, to get more details see tests. Basic Symfony DI config (symfony/dependency-injection) to get rates from Monobank looks like this:

services:
  app.currency.remote.service:
    class: Currency\Service\CurrencyService
    arguments:
      - '@app.currency.repository'
      - '@app.currency.rate.repository'

  app.currency.rate.repository:
    class: Currency\Repository\EntityRepository
    arguments:
      - '@app.currency.rate.provider'


  app.currency.rate.provider:
    class: Currency\DataProvider\Rate\MonobankRateDataProvider
    arguments:
      - '@app.currency.rate.client.monobank'
      - !php/enum Currency\Enum\Code::UAH
      - '@app.currency.rate.dta_mapper.monobank'

  app.currency.rate.dta_mapper.monobank:
    class: Currency\Mapper\Rate\RateDataMapper

  app.currency.rate.client.monobank:
    class: Monobank\MonobankClient
    arguments:
      - '@app.currency.rate.client.guzzle'
      - '@app.currency.rate.client.monobank.empty_token'

  app.currency.rate.client.monobank.empty_token:
    class: Monobank\ValueObject\Token
    arguments:
      - 'empty_token'

  app.currency.rate.client.guzzle:
    class: GuzzleHttp\Client

  app.currency.repository:
    class: Currency\Repository\EntityRepository
    arguments:
      - '@app.currency.data_provider'

  app.currency.data_provider:
    class: Currency\DataProvider\CurrencyConfigDataProvider
    arguments:
      - '@app.currency.config.processor'
      - '@app.currency.config.definition'
      - '@app.currency.mapper'

  app.currency.config.processor:
    class: Symfony\Component\Config\Definition\Processor

  app.currency.config.definition:
    class: Currency\Configuration\CurrencyConfiguration

  app.currency.mapper:
    class: Currency\Mapper\CurrencyMapper

How to use

To use core functional you need to init one of the service form Currency\Service namespace and then use it according to provided interface.
