# mav-prices
JavaScript module for **finding railway connection prices** using the [Magyar Államvasutak](https://jegy.mav.hu/) (MÁV, Hungarian State Railways) API. Inofficial, using an endpoint by _Magyar Államvasutak_. Please ask them for permission before using this module in production.
Supports both **international** connections from/to Hungary and **domestic** Hungarian connections. The MAV API requires at least one Hungarian station as departure or destination for international queries.

## Installation
```bash
npm install mav-prices
```
## Usage
`queryPrices()` returns a `Promise` that will resolve with a list of offers.
```javascript
import { queryPrices } from 'mav-prices';
queryPrices(from, to, [date], [opt]).then(…)
```
`from` and `to` must be MAV station IDs like `"008099970"`.
`date` must be a `Date` object; if empty, the current datetime will be used.
With `opt`, you can override the default options, which look like this:
```js
{
class: 2, // 1 or 2 for first or second class
seatReservation: false,
directConnection: false,
duration: 480, // search for connections within n minutes after departure date (default: undefined; note: 1 API request per 480 minutes will be sent)
longerTransferTime: false, // >=10 minutes transfer time guaranteed
isArrivalDate: false, // specify whether date parameter is arrival or departure date; ignored if duration is set
raw: false, // include raw API data (offerIdentity, serializedOfferData, trainIds) for booking workflows
intermediateStations: [ // 0-3 objects for intermediate stations (sample object is not set as default)
{
stationCode: "008062648", // station ID
durationOfStay: 5 // in minutes (max: 59 (officially), but more seems to work as well);
// set to 0 if train should at least pass through station
}
],
travellers: [ // one or more objects; up to six people
{
age: 30, // passenger age — automatically selects the correct type for domestic/international
discounts: [], // discount IDs — see below; inapplicable discounts are silently ignored
}
],
}
```
Domestic mode is detected automatically when both station codes start with `0055` (Hungarian). Prices are converted to EUR using the MÁV exchange rate; the original HUF amount is included as `originalAmount`/`originalCurrency`.
```js
// Budapest-Keleti to Debrecen, one adult — domestic is auto-detected
queryPrices('005510017', '005513912', when).then(…)
```
Available passenger types (auto-selected via `age`)
Passenger types are resolved automatically from the `age` field. The correct type for domestic or international is selected based on the detected route.

## Response
The result will be a list of [_Friendly Public Transport Format_](https://github.com/public-transport/friendly-public-transport-format) `journey` objects.
With `from = '008099970'`, `to = '005501362'` and `date = new Date('2023-01-09T09:30:00.000Z')`, the result looked like this:

For domestic connections, prices are converted from HUF to EUR using the MÁV exchange rate. The original amount is preserved:
```js
price: {
amount: 13.82, // converted to EUR
currency: 'EUR',
name: 'Ticket',
trainDependent: true,
refundable: false,
originalAmount: 5250, // original HUF price
originalCurrency: 'HUF',
}
```
