## Documentation
Most methods accept JS objects, except for methods with only one parameter. These can be populated using parameters specified by FTX's API documentation.
- [FTX REST API Documentation](https://docs.ftx.com/#rest-api).
- [FTX Websocket API Documentation](https://docs.ftx.com/#websocket-api).
## Structure
This project uses typescript. Resources are stored in 3 key structures:
- [src](./src) - the whole connector written in typescript
- [lib](./lib) - the javascript version of the project (compiled from typescript). This should not be edited directly, as it will be overwritten with each release.
- [dist](./dist) - the packed bundle of the project for use in browser environments.
- [examples](./examples) - demonstrations on various workflows using this library

# Usage
Create API credentials at FTX
- [FTX.com](https://ftx.com/#a=ftxapigithub)
## REST API Clients
Import and instance the `RestClient` to access all REST API methods.
- All methods return promises.
- Supports subaccounts.
### Example
To use the REST APIs, import the `RestClient`. Click here to expand and see full sample:
```javascript
const { RestClient } = require('ftx-api');
const restClientOptions = {
// override the max size of the request window (in ms)
recv_window?: number;
// how often to sync time drift with FTX servers
sync_interval_ms?: number | string;
// Default: false. Disable above sync mechanism if true.
disable_time_sync?: boolean;
// Default: false. If true, we'll throw errors if any params are undefined
strict_param_validation?: boolean;
// Optionally override API protocol + domain
// e.g 'https://ftx.us/api'
baseUrl?: string;
// Default: true. whether to try and post-process request exceptions.
parse_exceptions?: boolean;
// Subaccount nickname URI-encoded
subAccountName?: string;
};
const API_KEY = 'xxx';
const PRIVATE_KEY = 'yyy';
const client = new RestClient(
API_KEY,
PRIVATE_KEY,
// restClientOptions,
// requestLibraryOptions
);
client.getMarkets()
.then(result => {
console.log("getMarkets result: ", result);
})
.catch(err => {
console.error("getMarkets error: ", err);
});
client.setAccountLeverage(5)
.then(result => {
console.log("setAccountLeverage result: ", result);
})
.catch(err => {
console.error("setAccountLeverage error: ", err);
});
```
WebSocket channels can be subscribed to via the `WebsocketClient`. Click here to expand and see full sample:
```javascript
const { WebsocketClient } = require('ftx-api');
const API_KEY = 'xxx';
const PRIVATE_KEY = 'yyy';
const wsConfig = {
key: API_KEY,
secret: PRIVATE_KEY,
/*
The following parameters are optional:
*/
// Subaccount nickname
// subAccountName: 'sub1',
// how long to wait (in ms) before deciding the connection should be terminated & reconnected
// pongTimeout: 1000,
// how often to check (in ms) that WS connection is still alive
// pingInterval: 10000,
// how long to wait before attempting to reconnect (in ms) after connection is closed
// reconnectTimeout: 500,
// config options sent to RestClient (used for time sync). See RestClient docs.
// restOptions: { },
// config for axios used for HTTP requests. E.g for proxy support
// requestOptions: { }
// override which URL to use for websocket connections
// wsUrl: 'wss://example.ftx.com/ws'
};
const ws = new WebsocketClient(wsConfig);
// subscribe to multiple topics at once
ws.subscribe(['fills', 'orders']);
// and/or subscribe to individual topics on demand
ws.subscribe('fills');
// and/or subscribe to complex topics on demand, one at a time
ws.subscribe({
channel: 'trades',
market: 'BTC-PERP'
});
// or as a list of complex topics
ws.subscribe([
{
channel: 'trades',
market: 'BTC-PERP'
},
{
channel: 'orderbookGrouped',
market: 'BTC-PERP',
grouping: 500
}
]);
// Listen to events coming from websockets. This is the primary data source
ws.on('update', data => {
console.log('update', data);
});
// Optional: Listen to websocket connection open event (automatic after subscribing to one or more topics)
ws.on('open', ({ event }) => {
console.log('connection opened');
});
// Optional: Listen to responses to websocket queries (e.g. the response after subscribing to a topic)
ws.on('response', response => {
console.log('response', response);
});
// Optional: Listen to connection close event. Unexpected connection closes are automatically reconnected.
ws.on('close', () => {
console.log('connection closed');
});
// Optional: Listen to raw error events.
// Note: responses to invalid topics are currently only sent in the "response" event.
ws.on('error', err => {
console.error('ERR', err);
});
```

```javascript
const { WebsocketClient, DefaultLogger } = require('ftx-api');
// Disable all logging on the silly level
DefaultLogger.silly = () => {};
const ws = new WebsocketClient(
{ key: 'xxx', secret: 'yyy' },
DefaultLogger
);
