# xapi-node

This project is made possible to get data from Forex market, execute market or limit order with NodeJS/JS through WebSocket connection

This module may can be used for [BFB Capital](https://my.bfb.by/#/registration?ref=3030057) and [X-Trade Brokers](https://www.xtb.com/en) xStation5 accounts

### 1. Install via [npm](https://www.npmjs.com/package/xapi-node)

```
npm i xapi-node
```

### 2. Example usage
#### Authentication
```ts
// TypeScript
import XAPI from 'xapi-node';

const x = new XAPI({
    accountId: '(xStation5) accountID',
    password: '(xStation5) password',
    type: 'real' // or demo
});

x.connect();

x.onReady(() => {
    console.log('Connection is ready');
    
    // Disconnect
    x.disconnect().then(() => console.log('Disconnected'));
});
x.onReject((e) => {
    console.error(e);
});
```
#### Authentication only for XTB accounts
```ts
// TypeScript
import XAPI from 'xapi-node';

const x = new XAPI({
    accountId: '(xStation5) accountID',
    password: '(xStation5) password',
    host: 'ws.xtb.com', // only for XTB accounts
    type: 'real' // or demo
});

x.connect();

x.onReady(() => {
    console.log('Connection is ready');
    
    // Disconnect
    x.disconnect().then(() => console.log('Disconnected'));
});
x.onReject((e) => {
    console.error(e);
});
```

    offset: 0,
    order: 0,
    price: 100,
    sl: 0,
    symbol: 'BITCOIN',

x.Stream.listen.getTickPrices((data) => {
    console.log(data.symbol + ': ' + data.ask + ' | ' + data.askVolume + ' volume | ' + data.level + ' level' );
});

x.onReady(() => {
    x.Stream.subscribe.getTickPrices('EURUSD')
        .catch(() => { console.error('subscribe for EURUSD failed')});
});
/* output
EURUSD: 1.10912 | 500000 volume | 0 level

```ts
import Logger4 from 'logger4';

const logger = new Logger4({

    path: null,
    directorySizeLimitMB: null
});

const x = new XAPI({...loginConfig, logger});

x.logger.on((tag, log, type, params) => {
    // You can bind your log module here
    console.log({
        tag,
        log,
        type,
        params
    });
