# Welcome Krypto CoinPair Average Calculator
The `Krypto.Binance` and `Krypto.CoinPair` servers are started along with application.
## Project Highlighted Module
### Krypto.CoinPair
This module simulates a Persistent Server for subscribing the coinpair and storing the prices of coinpair using `GenServer`.
It will start as soon as our `krypto` app starts.
## Development Technologies
At the moment of developing this project, I used the following versions of
Elixir and Erlang.
```elixir
iex> mix hex.info
Hex: 2.0.6
Elixir: 1.16.1
OTP: 26.2.2
Built with: Elixir 1.16.1 and OTP 24.3.4.16
```
# Running Application
## 1) mix release krypto
```
mix deps.get
mix release krypto
```
I added the releases path to `./releases`
So, we are provided with following commands.
```
Release created at releases
# To start your system
releases/bin/krypto start
Once the release is running:
# To connect to it remotely
releases/bin/krypto remote
# To stop it gracefully (you may also send SIGINT/SIGTERM)
releases/bin/krypto stop
To list all commands:
releases/bin/krypto
```
#### 2) iex -S mix
Running Interactively
## Project Challenges
- Websockex Integration (Binance) Subscription Implementation.
- CoinPair Server for subscribing and updating the coinpair prices.
## Usage of Application
When the application starts, we have two modules available. `Krypto.Binance` and `Krypto.CoinPair`. The `Krypto.Binance` establish a websocket connection as soon as the application starts.
## Subscribing a coinpair
```elixir
iex> Krypto.CoinPair.subscribe "btcusdt"
:ok
iex> Krypto.CoinPair.subscribe "ethusdt"
:ok
```
## Getting Average price for coinpair
```elixir
iex> Krypto.CoinPair.get_average "btcusdt"
{:ok, 64019.6706875}
iex> Krypto.CoinPair.get_average "ethusdt"
{:ok, 3150.221481481482}
```
## Debugging
```elixir
iex> :sys.trace(Process.whereis(Krypto.Binance), true)
```
## Overall Project Experience
I felt it is a well framed to test core concepts of Elixir as project made me to code in all the core concepts of Elixir like `GenServers`, `Enumaration`, `message communications`, `websocket`.
**Thank You :)**
