**Currency** is a currency converter written in Angular.

![][preview]

Features
---

- Convert multiple currencies at the same time
- Rates come from http://xe.com/ (*scrapped using my [API](https://github.com/pioug/currency/blob/master/api/index.js)*)
- Save selected currencies and typed value in localStorage

Building
---

The `server` task in [`gulpfile.js`](https://github.com/pioug/currency/blob/master/gulpfile.js) and the API server rely on a Koa server. Koa currently requires node 0.11.x for the harmony flag. Launch them with the following command:

```bash
# frontend environment
node --harmony-generators `which gulp` serve

# backend environment
node --harmony-generators api
```

API
---

*Took down the endpoint because it does not respect the XE’s Terms of Use*

```
GET /currencies
```

```json
[
  {
    "code": "AED",
    "name": "Emirati Dirham"
  },
  {
    "code": "AFN",
    "name": "Afghan Afghani"
  },
  {
    "code": "ALL",
    "name": "Albanian Lek"
  },
  ...
]
```

- `GET /rate/:from/:to` will return exchange rate between specified currencies.
  - `:from` *three-character currency code*
  - `:to` *three-character currency code*

```
GET /rate/xbt/eur
```

```json
{
  "from": "XBT",
  "to": "EUR",
  "rate": 431.951,
  "timestamp": "2014-03-08T12:56:00.000Z"
}
```
