Real time Currency Tracker using PubNub C# SDK

Realtime Currency Tracker Dashboard using PubNub and C#/.NET

Introduction

A web based micro dashboard for displaying currency exchange rates using PubNub C# SDK and JS SDK. It displays the current currency conversion rate for EUR, AUD, CYN and INR against USD. The application source code is divided into a server part which is under server location, and client part which is under client location.

##Setup and Build

Server

Clone the repository and open the server source code in Visual Studio editor. The source code folder is a VS solution which can be opened by choosing this file.

Before building the solution , make sure that you have

1. PubNub publish and subscribe keys. Update the web.config file with the publish and subscribe keys.

   Update the publish key here

   Update the subscribe key here

2. CurrencyLayer.com subscription. Update the following line in the source code with your currencylayer API keys https://github.com/shyampurk/currency-tracker-csharp/blob/master/server/CurrencyTrack/CurrencyTrack/ScheduledTask.cs#L21

   Update the access_key URL parameter with your currencylayer.com subscription key

Build the solution from within Visual Studio. You will get a message in the Output window as follows

  1>------ Build started: Project: CurrencyTrack, Configuration: Debug Any CPU ------
  1>  CurrencyTrack -> <YOUR_PATH>\CurrencyTrack\CurrencyTrack\bin\CurrencyTrack.dll
  ========== Build: 1 succeeded, 0 failed, 0 up-to-date, 0 skipped ==========

  where YOUR_PATH is the local path of the solution folder in your build system 

Client

Update the javascript source code with the same set of PubNub keys that you have used at the server.

Update the publish key here

Update the subscribe key here

Run the Demo

Step 1 - Run the server application either within Visual Studio or by uploading it to Azure cloud.

Step 2 - Run the client app by opening the main html file in browser.

Allow the application to run for a few hours. You will see updated currency convertion values getting displayed in the client dashboard every couple of hours ( depending on the time and day of the week). Once the application is running for a few hours, you can also see the historical currency rate trends by clicking on the 'Trend' button against each currency in the dashboard.
