# Rial Exchange Rates Archive

This repository serves as the archive for Iranian Rial (IRR) currency conversion rates sourced
from [bonbast.com](https://bonbast.com/). The exchange rates are automatically updated every day using a GitHub Actions
workflow.

The primary goal of this repository is to maintain a comprehensive historical record of Iranian Rial exchange rates over
time.

Please note that all prices in this repository are in `Toman`.

## Structure

The repository is organized into two main directories: `gregorian` and `jalali`. Both directories have the same format
and type of files, with the only difference being the date.

```text
├── gregorian
│   └── {year}
│       ├── full -> contain every day in that year
│       └── {month}
│           ├── full -> contain every day in that month
│           └── {day}
├── jalali
│   └── {year}
│       ├── full -> contain every day in that year
│       └── {month}
│           ├── full -> contain every day in that month
│           └── {day}
└── automated-python-scripts
```

### `{year}/{month}/{day}` file model

These files contain the daily currency conversion rates. They all have the same DTO for convenience.

> Please note that the starting file is always 2012/10/09 for gregorian and 1391/07/18 for jalali.

```text
{
  "{currency-code}": {
    "name": <string>,
    "sell": <int>,
    "buy": <int>
  }
}
```

### `full` file model

If a year or a month has ended and the last day exists, a corresponding `full` file is available in the same directory.
This file contains every single day with the same DTO structure.

```text
{
  "{date}": {
    "{currency-code}": {
      "name": <string>,
      "sell": <int>,
      "buy": <int>
    }
  }
}
```

## Files

Every night, automated scripts generate the following types of release files:

- `{calende}_all.json`: Contains all the information from the start
- `{calende}_all.min.json`: Similar to the previous one, but whitespaces and the `name` field (from currency DTO) is
  removed
- `{calende}_imp.min.json`: Similar to the previous one, but only for USD, EUR, and GBP
- `{calende}_31days.min.json`: Contains all currencies in the past 31 days
- `{calende}_7days.min.json`: Contains all currencies in the past 7 days

> Note: Only the last 10 releases are retained. That means you always have to a get the last one like this:
> ```bash
> curl -Ls https://github.com/SamadiPour/rial-exchange-rates-archive/releases/latest/download/gregorian_imp.min.json | jq
> ```

### `data` branch files

This repository also includes an orphan branch that contains generated outputs. The branch will always have just one
commit and no history. The data stored in this branch is identical to the release section, but it also includes the
following files:

- `/currency/{currency-code}.json`: Contains currency specific information from the start

> CORS Issue: If you are encountering CORS error while getting the release files, you can instead use the files stored
> in the `data` branch. For example, try one of these two links:
> ```text
> - https://raw.githubusercontent.com/SamadiPour/rial-exchange-rates-archive/data/gregorian_imp.min.json
> - https://cdn.jsdelivr.net/gh/SamadiPour/rial-exchange-rates-archive@data/gregorian_imp.min.json
> ```

## Usage

You can access the historical exchange rate data by exploring the contents of this repository. The data is organized and
stored in a structured format, allowing for easy retrieval and analysis.

### Getting exchange rates for specific date

The output of these examples will be like this:

```json
{
  "usd": {
    "name": "US Dollar",
    "sell": 3400,
    "buy": 3300
  }
}
```

```bash
# == Bash + jq ==
curl -s https://raw.githubusercontent.com/SamadiPour/rial-exchange-rates-archive/main/gregorian/2015/10/15
```

```python
# == Python ==
import requests
import json

response = requests.get(
    'https://raw.githubusercontent.com/SamadiPour/rial-exchange-rates-archive/main/gregorian/2015/05/10'
)
response.raise_for_status()
prices = json.loads(response.text)
print(prices)
print(prices.get('usd', {}).get('buy', None))
```

```js
// JavaScript
fetch('https://raw.githubusercontent.com/SamadiPour/rial-exchange-rates-archive/main/jalali/1395/05/01')
    .then(response => response.json())
    .then(data => {
        console.log(data);
        console.log(data.usd.buy);
    })
    .catch(error => {
        console.error('Error:', error)
    })
```

### Converting `full` file to date-price map/dict

The output of these examples will be like this:

```json
{
  "2013/01/01": 3205,
  "2013/01/02": 3190,
  "2013/01/03": 3195
}
```

Examples:

```bash
# == Bash + jq ==
curl -s https://raw.githubusercontent.com/SamadiPour/rial-exchange-rates-archive/main/gregorian/2015/10/full | jq 'to_entries | map({key: .key, value: .value.usd.buy}) | from_entries'
```

```python
# == Python ==
import requests
import json

response = requests.get(
    'https://raw.githubusercontent.com/SamadiPour/rial-exchange-rates-archive/main/gregorian/2015/full'
)
response.raise_for_status()
data = json.loads(response.text)
prices = {key: value['eur']['buy'] for key, value in data.items()}
print(prices)
```

```js
// JavaScript
fetch('https://raw.githubusercontent.com/SamadiPour/rial-exchange-rates-archive/main/jalali/1395/05/full')
    .then(response => response.json())
    .then(data => {
        const prices = Object.fromEntries(
            Object.entries(data).map(([key, value]) => [key, value.usd.sell])
        );
        console.log(prices);
    })
    .catch(error => {
        console.error('Error:', error)
    })
```

### Converting `full` files to array/list

The output of these examples will be like this:

```json
[
  3205,
  3190,
  3195
]
```

Examples:

```bash
# == Bash + jq ==
curl -s https://raw.githubusercontent.com/SamadiPour/rial-exchange-rates-archive/main/gregorian/2015/10/full | jq '[.[] | .usd.buy]'
```

```python
# == Python ==
import requests
import json

response = requests.get(
    'https://raw.githubusercontent.com/SamadiPour/rial-exchange-rates-archive/main/gregorian/2015/full'
)
response.raise_for_status()
data = json.loads(response.text)
prices = (value["eur"]["buy"] for value in data.values())
print(prices)
```

```js
// JavaScript
fetch('https://raw.githubusercontent.com/SamadiPour/rial-exchange-rates-archive/main/jalali/1395/05/full')
    .then(response => response.json())
    .then(data => {
        const prices = Object.values(data).map(item => item.usd.sell);
        console.log(prices);
    })
    .catch(error => {
        console.error('Error:', error)
    })
```
