# Alpaca Trade API JS
[](https://www.npmjs.com/package/@alpacahq/alpaca-trade-api)
[](https://circleci.com/gh/alpacahq/alpaca-trade-api-js)
Node.js library for Alpaca Trade API.
## API Documentation
The REST API documentation can be found in https://docs.alpaca.markets. For detailed information about an endpoint, please consult the REST API docs. Documentation specific to this library can be found below.
### News
We introduced Typescript support recently, which allows you to use strongly typed data structures and better IDE experience if you are using it.
## Installation
```sh
npm install --save @alpacahq/alpaca-trade-api
```
## Runtime Dependencies
- Node.js v16.9 or newer
- npm version 6 and above
## Usage
Import the module first.
```js
const Alpaca = require('@alpacahq/alpaca-trade-api')
```
Instantiate the API with config options, obtained from the dashboard at app.alpaca.markets.
```js
const alpaca = new Alpaca({
keyId: 'AKFZXJH121U18SHHDRFO',
secretKey: 'pnq4YHlpMF3LhfLyOvmdfLmlz6BnASrTPQIASeiU',
paper: true,
})
```
Note: `keyId` and `secretKey` may also be specified by setting the `APCA_API_KEY_ID` and `APCA_API_SECRET_KEY` environment variables, respectively. Also, rather than specifying `paper`, you may set `APCA_API_BASE_URL` as an environment variable to direct your API calls to the paper trading API.
Call methods, which will return a promise.
```js
alpaca.getAccount().then((account) => {
console.log('Current Account:', account)
})
```
The websocket api is a good way to watch and react to the market
we have 2 types of websockets:
- data websocket: get updates to data equities
- account/trade websocket: get updates on your account
please refer to this [example](https://github.com/alpacahq/alpaca-trade-api-js/blob/master/examples/websocket_example_datav2.js)
code to see how to use the websockets.
##### Data WS
The Alapca websocket service now supports V2. Make sure you update your old sample code accordingly.
You could use it even if you don't have a funded account.
## Methods
As a general rule, required method parameters are passed as plain function arguments, and the final parameter is an object containing any optional parameters to the method.

### Data API - Crypto
All the functions are similar to the stock ones.
#### Trades
* ```ts
getCryptoTrades(
symbols: Array,
options: GetCryptoTradesParams,
config?: any,
): AsyncGenerator;
```
* ```ts
getLatestCryptoTrades(
symbols: Array,
config?: any
): Promise>;
```
#### Quotes
* ```ts
getCryptoQuotes(
symbols: Array,
options: GetCryptoQuotesParams,
config?: any,
): AsyncGenerator;
```
* ```ts
getLatestCryptoQuotes(
symbols: Array,
config?: any,
): Promise>;
```
#### Bars
* ```ts
getCryptoBars(
symbols: Array,
options: GetCryptoBarsParams,
config?: any,
): AsyncGenerator;
```
* ```ts
getLatestCryptoBars(
symbols: Array,
config?: any,
): Promise>;
```
#### Snapshots
* ```ts
getCryptoSnapshots(
symbol: Array,
config?: any,
): Promise;
```
### Data API - Options
#### Bars
* ```ts
getOptionBars(
symbols: Array,
options: GetOptionBarsParams,
config?: any,
): Promise>;
```
#### Trades
* ```ts
getOptionTrades(
symbols: Array,
options: GetOptionTradesParams,
config = any,
): Promise>;
```
* ```ts
getOptionLatestTrades(
symbols: Array,
config = any,
): Promise>;
```

): Promise;
```
### Data API - Corporate Actions
* ```ts
getCorporateActions(
symbols: Array,
options: GetCorporateActionParams,
config = any
): Promise;
```
### Websockets
You can use data websocket with or without a funded account.
#### Working with websocket
```ts
const websocket = alpaca.data_stream_v2;
websocket.onConnect(() => {
websocket.subscribeForTrades(["AAPL"]);
});
websocket.onStateChange((status) => {
console.log("Status:", status);
});
websocket.onError((err) => {
console.log("Error:", err);
});
websocket.onStockTrade((trade) => {
console.log("Trade:", trade);
});
websocket.connect();
```
###### Output:
```python
Status: connecting
Status: authenticating
Status: connected
Status: authenticated
Trade: {
T: 't',
Symbol: 'AAPL',
ID: 68,
Exchange: 'V',
Price: 165.02,
Size: 50,
Conditions: [ '@', 'T', 'I' ],
Tape: 'C',
Timestamp: 2022-04-19T12:50:29.214Z
}
```
* The websocket is created when you first create the Alpaca instance
* `const websocket = alpaca.data_stream_v2`: Get the websocket client instance.
* `websocket.connect()`: Connect to the Alpaca server using websocket.
* `websocket.onConnect(() => {})`: all the following code will be executed after
the user authentication. You can also subscribe and unsubscribe for data
outside this function.
* `websocket.subscribeForTrades(["AAPL"])`: Subscribe for trades data for the
given symbol(s). You can do the same with quotes, bars, dailyBars, updatedBars, statuses and lulds.
* `websocket.onStockTrade((trade) => {})`: Get the data by subscribing for the trade data event
in JS/TS and process it inside this function.
* `websocket.unsubscribeFromTrades(["symbol"])`: Unsubscribe from symbol(s).
* `websocket.onDisconnect(() => {})` and `websocket.disconnect()`: the function
inside the `onDisconnect` will run when you disconnect then closes the connection
between the client and server.
Websocket client for real-time crypto and news data work the same. For a detailed example please take a look
at this [file](https://github.com/alpacahq/alpaca-trade-api-js/blob/master/examples/websocket_example_datav2.js).
