Rate

This project was created to show my skills using .NET Core to deliver the rate between a pair of currencies.

Problem

Write a .NET Core Console application that uses the contents of the XML file at https://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml and expose an HTTP endpoint to retrieve the rate for a specific currency pair. So a GET request to http://localhost:port/rate?currencypair=GBPUSD should return the rate to convert GBP to USD. The rates should be cached for one hour so we don’t download the file with every request.

Installing

Clone the project

Open the solution file in Visual Studio 2017.

Set LucasRosinelli.Rate.Api as your startup project and press "IIS Express" button. The API will run on:

http://localhost:50635/

You can ignore the initial page.

To execute on browser, type on address bar:

http://localhost:50635/rate?currencyPair=GBPUSD

If you prefer, you can use Postman(https://www.getpostman.com/) to GET the rate. NOTE: cache feature will works only if "Send no-cache header" is disabled. For more information: (https://www.getpostman.com/docs/v6/postman/launching_postman/settings).

To create the executable file for Win-x64 / Windows 10 machine, go to LucasRosinelli.Rate.Presentation.Console folder in "Command Prompt" and type:

dotnet publish -c Release -r win10-x64

Command line instructions

Open the EXE and type the currency pair you want to get the rate and press ENTER. You will get the rate. If you type an invalid curreny pair (different from 6 characters or currencies that doesn't exist), you will get an error message.

To exit, type "exit" or "quit" and press ENTER.

NOTE: the API must be running.
