 1 | # Coin Exchange Web Application
 2 | 
 3 | ![coin exchange dashboard](https://i.imgur.com/I4kQ9q6.png)
 4 | 
 5 | A mock digital currency exchange platform which allows users to buy and sell Bitcoin and Ethereum based on actual real-time market price. This web application is built with Sinatra Ruby framework. Features inspired by Coinbase exchange.
 6 | 
 7 | This app is deployed in Heroku: https://coin-exchange-sinatra.herokuapp.com/
 8 | 
 9 | The goal of creating this application to practice translating high-level requirements into working code, integrating third-party web APIs and translating them into user-friendly interfaces and charts. Dynamic input forms were rendered through the use of jQuery.
10 | Performance bottlenecks such as slow loading speed were addressed.
11 | 
12 | ## Installation
13 | Clone or download this git repository. Within the terminal opening the root of this project, execute the following line to install dependencies:
14 | 
15 | ```
16 | bundle install
17 | ```
18 | 
19 | ## Usage
20 | To run the server locally, execute:
21 | 
22 | ```
23 | bundle exec ruby cx.rb
24 | ```
25 | 
26 | Once Sinatra is running in the background, open up a web browser and enter `localhost:4567` in the URL address bar to begin.
27 | 
28 | ## API Utilization
29 | Third-party APIs are used to integrate real-time BTC and ETH prices into the application and to display a 30-day BTC and ETH chart.
30 | - API for real-time BTC and ETH prices: https://min-api.cryptocompare.com/data/pricemulti?fsyms=BTC,ETH&tsyms=USD
31 | - API information for historical hourly price data: https://www.cryptocompare.com/api/#-api-data-histohour
32 | 
33 | ## Offline Mode
34 | In the case where the application fails to fetch real-time data, the last retrieved price data will be used. This will apply to buy/sell prices as well as historical chart data.
35 | It is possible to run the application entirely off-line. For the best user experience, it is recommended that you have an active Internet connection.
36 | 
37 | ### Sign-up Bonus
38 | User will receive a sign-up bonus funding of virtual USD balance into their account, which can be used to purchase mock BTC or ETH.
39 | 
40 | #### Default User
41 | If you do not wish to create a new account, you can use the default credentials:
42 | - username: `admin`
43 | - password: `secret`
44 | 
45 | ### Automatic logging out
46 | Signed-in user will be automatically logged out after a certain period of inactivity. On every account action (buy/sell/page navigation), the idle time will be reset.
47 | 
48 | ### Numbers
49 | Prices are updated real-time - which means the web app's exchange rates follow the actual markets. A strict price validation is implemented (price swing within 0.5%) so that users may not be able to manipulate the inputs to buy/sell at a false exchange rate.
50 | 
51 | ## Tests
52 | To run tests:
53 | ```
54 | bundle exec ruby test/cx_test.rb
55 | ```
56 | 
57 | Tests will now retrieve current price data from `cache_prices.yml`. This will prevent significant price fluctuations due to API response lagging time.
58 |

62 | [Chartkick](https://www.chartkick.com/), together with Google Charts are used for drawing beautiful charts.
63 | 
64 | [Crytocompare API](https://www.cryptocompare.com/api/) is used as an API source for all of the real-time pricing and historical price data.
