## Documentation
For detailed information, refer to the [Binance API Documentation](https://developers.binance.com/docs/derivatives/usds-margined-futures/general-info).
### REST APIs
All REST API endpoints are available through the [`rest-api`](./src/rest-api/rest-api.ts) module. Note that some endpoints require authentication using your Binance API credentials.
```typescript
import { DerivativesTradingUsdsFutures } from '@binance/derivatives-trading-usds-futures';
const configurationRestAPI = {
apiKey: 'your-api-key',
apiSecret: 'your-api-secret',
};
const client = new DerivativesTradingUsdsFutures({ configurationRestAPI });
client.restAPI
.exchangeInformation()
.then((res) => res.data())
.then((data) => console.log(data))
.catch((err) => console.error(err));
```
More examples can be found in the [`examples/rest-api`](./examples/rest-api/) folder.
#### Configuration Options
The REST API supports the following advanced configuration options:
- `timeout`: Timeout for requests in milliseconds (default: 1000 ms).
- `proxy`: Proxy configuration:
- `host`: Proxy server hostname.
- `port`: Proxy server port.
- `protocol`: Proxy protocol (http or https).
- `auth`: Proxy authentication credentials:
- `username`: Proxy username.
- `password`: Proxy password.
- `keepAlive`: Enable HTTP keep-alive (default: true).
- `compression`: Enable response compression (default: true).
- `retries`: Number of retry attempts for failed requests (default: 3).
- `backoff`: Delay in milliseconds between retries (default: 1000 ms).
- `httpsAgent`: Custom HTTPS agent for advanced TLS configuration.
- `privateKey`: RSA or ED25519 private key for authentication.
- `privateKeyPassphrase`: Passphrase for the private key, if encrypted.
##### Timeout
You can configure a timeout for requests in milliseconds. If the request exceeds the specified timeout, it will be aborted. See the [Timeout example](./docs/rest-api/timeout.md) for detailed usage.
##### Proxy
The REST API supports HTTP/HTTPS proxy configurations. See the [Proxy example](./docs/rest-api/proxy.md) for detailed usage.
##### Keep-Alive
Enable HTTP keep-alive for persistent connections. See the [Keep-Alive example](./docs/rest-api/keepAlive.md) for detailed usage.
##### Compression
Enable or disable response compression. See the [Compression example](./docs/rest-api/compression.md) for detailed usage.
##### Retries
Configure the number of retry attempts and delay in milliseconds between retries for failed requests. See the [Retries example](./docs/rest-api/retries.md) for detailed usage.
##### HTTPS Agent
Customize the HTTPS agent for advanced TLS configurations. See the [HTTPS Agent example](./docs/rest-api/httpsAgent.md) for detailed usage.
##### Key Pair Based Authentication
The REST API supports key pair-based authentication for secure communication. You can use `RSA` or `ED25519` keys for signing requests. See the [Key Pair Based Authentication example](./docs/rest-api/key-pair-authentication.md) for detailed usage.
##### Certificate Pinning
To enhance security, you can use certificate pinning with the `httpsAgent` option in the configuration. This ensures the client only communicates with servers using specific certificates. See the [Certificate Pinning example](./docs/rest-api/certificate-pinning.md) for detailed usage.
#### Error Handling
The REST API provides detailed error types to help you handle issues effectively:
- `ConnectorClientError`: General client error.
- `RequiredError`: Thrown when a required parameter is missing.
- `UnauthorizedError`: Indicates missing or invalid authentication credentials.
- `ForbiddenError`: Access to the requested resource is forbidden.
- `TooManyRequestsError`: Rate limit exceeded.
- `RateLimitBanError`: IP address banned for exceeding rate limits.
- `ServerError`: Internal server error.
- `NetworkError`: Issues with network connectivity.
- `NotFoundError`: Resource not found.
- `BadRequestError`: Invalid request.
See the [Error Handling example](./docs/rest-api/error-handling.md) for detailed usage.
#### Testnet
For testing purposes, `/fapi/*` endpoints can be used in the [Futures Testnet](https://testnet.binancefuture.com/). Update the `basePath` in your configuration:
```typescript
import { DerivativesTradingUsdsFutures, DERIVATIVES_TRADING_USDS_FUTURES_REST_API_TESTNET_URL } from '@binance/derivatives-trading-usds-futures';
const configurationRestAPI = {
apiKey: 'your-api-key',
apiSecret: 'your-api-secret',
basePath: DERIVATIVES_TRADING_USDS_FUTURES_REST_API_TESTNET_URL,
};
const client = new DerivativesTradingUsdsFutures({ configurationRestAPI });
```
If `basePath` is not provided, it defaults to `https://fapi.binance.com`.
### Websocket APIs
The WebSocket API provides request-response communication for market data and trading actions. Use the [`websocket-api`](./src/websocket-api/websocket-api.ts) module to interact with these endpoints.
```typescript
import { DerivativesTradingUsdsFutures } from '@binance/derivatives-trading-usds-futures';
const configurationWebsocketAPI = {
apiKey: 'your-api-key',
apiSecret: 'your-api-secret',
};
const client = new DerivativesTradingUsdsFutures({ configurationWebsocketAPI });
client.websocketAPI
.connect()
.then((connection) => connection.positionInformation())
.then((res) => console.log(res.data))
.catch((err) => console.error(err));
```
More examples are available in the [`examples/websocket-api`](./examples/websocket-api/) folder.
#### Configuration Options
The WebSocket API supports the following advanced configuration options:
- `timeout`: Set the timeout for WebSocket requests (default: 5000 ms).
- `reconnectDelay`: Specify the delay between reconnection attempts (default: 5000 ms).
- `compression`: Enable or disable compression for WebSocket messages (default: true).

##### WebSocket Agent
Customize the agent for advanced configurations. See the [WebSocket Agent example](./docs/websocket-api/agent.md) for detailed usage.
##### Connection Mode
Choose between `single` and `pool` connection modes for WebSocket connections. The `single` mode uses a single WebSocket connection, while the `pool` mode uses a pool of WebSocket connections. See the [Connection Mode example](./docs/websocket-api/connection-mode.md) for detailed usage.
##### Key Pair Based Authentication
Use RSA or ED25519 private keys for WebSocket API authentication. See the [Key Pair Authentication example](./docs/websocket-api/key-pair-authentication.md) for detailed usage.
##### Certificate Pinning
To enhance security, you can use certificate pinning with the `agent` option in the configuration. This ensures the client only communicates with servers using specific certificates. See the [Certificate Pinning example](./docs/websocket-api/certificate-pinning.md) for detailed usage.
#### Testnet
For testing purposes, the Websocket API also supports a testnet environment. Update the `wsURL` in your configuration:
```typescript
import { DerivativesTradingUsdsFutures, DERIVATIVES_TRADING_USDS_FUTURES_WS_API_TESTNET_URL } from '@binance/derivatives-trading-usds-futures';
const configurationWebsocketAPI = {
apiKey: 'your-api-key',
apiSecret: 'your-api-secret',
wsURL: DERIVATIVES_TRADING_USDS_FUTURES_WS_API_TESTNET_URL,
};
const client = new DerivativesTradingUsdsFutures({ configurationWebsocketAPI });
```
If `wsURL` is not provided, it defaults to `wss://ws-fapi.binance.com/ws-fapi/v1`.
### Websocket Streams
WebSocket Streams provide real-time data feeds for market trades, candlesticks, and more. Use the [websocket-streams](./src/websocket-streams/websocket-streams.ts) module to subscribe to these streams.
```typescript
import { DerivativesTradingUsdsFutures, DERIVATIVES_TRADING_USDS_FUTURES_WS_STREAMS_PROD_URL } from '@binance/derivatives-trading-usds-futures';
const configurationWebsocketStreams = {
wsURL: DERIVATIVES_TRADING_USDS_FUTURES_WS_STREAMS_PROD_URL,
};
const client = new DerivativesTradingUsdsFutures({ configurationWebsocketStreams });
client.websocketStreams
.connect()
.then((connection) => {
const stream = connection.allBookTickersStream();
stream.on('message', (data) => console.info(data));
})
.catch((err) => console.error(err));
```
More examples are available in the [`examples/websocket-streams`](./examples/websocket-streams/) folder.
#### Configuration Options
The WebSocket Streams API supports the following advanced configuration options:
- `reconnectDelay`: Specify the delay between reconnection attempts (default: 5000 ms).
- `compression`: Enable or disable compression for WebSocket messages (default: true).
- `agent`: Customize the WebSocket agent for advanced configurations.
- `mode`: Choose between `single` and `pool` connection modes.
- `single`: A single WebSocket connection.
- `pool`: A pool of WebSocket connections.
- `poolSize`: Define the number of WebSocket connections in pool mode.
##### Reconnect Delay
Specify the delay in milliseconds between WebSocket reconnection attempts for streams. See the [Reconnect Delay example](./docs/websocket-streams/reconnect-delay.md) for detailed usage.
##### Compression
Enable or disable compression for WebSocket Streams messages. See the [Compression example](./docs/websocket-streams/compression.md) for detailed usage.
##### WebSocket Agent
Customize the agent for advanced configurations. See the [WebSocket Agent example](./docs/websocket-streams/agent.md) for detailed usage.
##### Connection Mode
Choose between `single` and `pool` connection modes for WebSocket Streams. The `single` mode uses a single WebSocket connection, while the `pool` mode uses a pool of WebSocket connections. See the [Connection Mode example](./docs/websocket-streams/connection-mode.md) for detailed usage.
##### Certificate Pinning
To enhance security, you can use certificate pinning with the `agent` option in the configuration. This ensures the client only communicates with servers using specific certificates. See the [Certificate Pinning example](./docs/websocket-streams/certificate-pinning.md) for detailed usage.
#### Subscribe to User Data Streams
You can consume the user data stream, which sends account-level events such as account and order updates. First create a listen-key via REST or WebSocket API; then:
```typescript
import { DerivativesTradingUsdsFutures, DERIVATIVES_TRADING_USDS_FUTURES_WS_STREAMS_PROD_URL } from '@binance/derivatives-trading-usds-futures';
const configurationWebsocketStreams = {
wsURL: DERIVATIVES_TRADING_USDS_FUTURES_WS_STREAMS_PROD_URL,
};
const client = new DerivativesTradingUsdsFutures({ configurationWebsocketStreams });
client.websocketStreams
.connect()
.then((connection) => {
const stream = connection.userData('listenKey');
stream.on('message', (data) => {
switch (data.e) {
case 'ACCOUNT_CONFIG_UPDATE':
console.log('account config update stream', data);
break;
case 'ORDER_TRADE_UPDATE':
console.log('order trade update stream', data);
break;
// …handle other variants…
default:
console.log('unknown stream', data);
break;
}
});
})
.catch((err) => console.error(err));
```
#### Unsubscribing from Streams
You can unsubscribe from specific WebSocket streams using the `unsubscribe` method. This is useful for managing active subscriptions without closing the connection.
```typescript
import { DerivativesTradingUsdsFutures, DERIVATIVES_TRADING_USDS_FUTURES_WS_STREAMS_PROD_URL } from '@binance/derivatives-trading-usds-futures';
const configurationWebsocketStreams = {
wsURL: DERIVATIVES_TRADING_USDS_FUTURES_WS_STREAMS_PROD_URL,
};
const client = new DerivativesTradingUsdsFutures({ configurationWebsocketStreams });
client.websocketStreams
.connect()
.then((connection) => {
const stream = connection.allBookTickersStream();
stream.on('message', (data) => console.info(data));
setTimeout(() => {
stream.unsubscribe();
console.log('Unsubscribed from allBookTickersStream stream');
}, 10000);
})
.catch((err) => console.error(err));
```
#### Testnet
Websocket Streams also support a testnet environment for development and testing. Update the `wsURL` in your configuration:
```typescript
import { DerivativesTradingUsdsFutures, DERIVATIVES_TRADING_USDS_FUTURES_WS_STREAMS_TESTNET_URL } from '@binance/derivatives-trading-usds-futures';
const configurationWebsocketStreams = {
wsURL: DERIVATIVES_TRADING_USDS_FUTURES_WS_STREAMS_TESTNET_URL,
};
const client = new DerivativesTradingUsdsFutures({ configurationWebsocketStreams });
```
If `wsURL` is not provided, it defaults to `wss://fstream.binance.com`.
### Automatic Connection Renewal
The WebSocket connection is automatically renewed for both WebSocket API and WebSocket Streams connections, before the 24 hours expiration of the API key. This ensures continuous connectivity.
## Testing
To run the tests:
```bash
npm install
npm run test
```
The tests cover:
- REST API endpoints
- WebSocket API and Streams
- Error handling and edge cases
