Structure

This project uses typescript. Resources are stored in 2 key structures:

src - the whole connector written in typescript
examples - some implementation examples & demonstrations. Contributions are welcome!

Usage

Create API credentials

Coinbase API Key Management

REST API

To use any of Coinbase's REST APIs in JavaScript/TypeScript/Node.js, import (or require) the client you want to use. We currently support the following clients:

CBAdvancedTradeClient

const { CBAdvancedTradeClient } = require('coinbase-api');
/**
 * Or, with import:
 * import { CBAdvancedTradeClient } from 'coinbase-api';
 */

// insert your API key details here from Coinbase API Key Management
const advancedTradeCdpAPIKey = {
  // dummy example keys to understand the structure

See all clients here for more information on all the functions or the examples for lots of usage examples. You can also check the endpoint function list here to find all available functions!

WebSockets

All available WebSockets can be used via a shared WebsocketClient. The WebSocket client will automatically open/track/manage connections as needed. Each unique connection (one per server URL) is tracked using a WsKey (each WsKey is a string - see WS_KEY_MAP for a list of supported values - WS_KEY_MAP can also be used like an enum).

Any subscribe/unsubscribe events will need to include a WsKey, so the WebSocket client understands which connection the event should be routed to. See examples below or in the examples folder on GitHub.

Data events are emitted from the WebsocketClient via the update event, see example below:

Public Websocket

const { WebsocketClient } = require('coinbase-api');
/**
 * Or, with import:
 * import { WebsocketClient } from 'coinbase-api';
 */

// public ws client, doesnt need any api keys to run
const client = new WebsocketClient();

// The WS Key (last parameter) dictates which WS feed this request goes to (aka if auth is required).
// As long as the WS feed doesn't require auth, you should be able to subscribe to channels without api credentials.
client.subscribe(
  {
    topic: 'status',
    payload: {
      product_ids: ['XRP-USD'],
    },
  },
  'advTradeMarketData',
);

Private Websocket

const { WebsocketClient } = require('coinbase-api');
/**
 * Or, with import:
 * import { WebsocketClient } from 'coinbase-api';
 */

// key name & private key, as returned by coinbase when creating your API keys.
// Note: the below example is a dummy key and won't actually work
const advancedTradeCdpAPIKey = {
  name: 'organizations/13232211d-d7e2-d7e2-d7e2-d7e2d7e2d7e2/apiKeys/d7e2d7e2-d7e2-d7e2-d7e2-d7e2d7e2d7e2',
  privateKey:
    '-----BEGIN EC PRIVATE KEY-----\nADFGHmkgnjdfg16k165kuu1kdtyudtyjdtyjytj/ADFGHmkgnjdfg16k165kuu1kdtyudtyjdtyjytj+oAoGCCqGSM49\nAwEHoUQDQgAEhtAep/ADFGHmkgnjdfg16k165kuu1kdtyudtyjdtyjytj+bzduY3iYXEmj/KtCk\nADFGHmkgnjdfg16k165kuu1kdtyudtyjdtyjytj\n-----END EC PRIVATE KEY-----\n',
};

const client = new WebsocketClient({
  // Either pass the full JSON object that can be downloaded when creating your API keys
  // cdpApiKey: advancedTradeCdpAPIKey,

  // Or use the key name as "apiKey" and private key (WITH the "begin/end EC PRIVATE KEY" comment) as "apiSecret"
  apiKey: advancedTradeCdpAPIKey.name,
  apiSecret: advancedTradeCdpAPIKey.privateKey,
});

Listening and subscribing to Websocket events

// add event listeners for websocket clients

client.on('open', (data) => {
  console.log('open: ', data?.wsKey);
});

// Data received
client.on('update', (data) => {
  console.info(new Date(), 'data received: ', JSON.stringify(data));
});

// Something happened, attempting to reconenct
client.on('reconnect', (data) => {
  console.log('reconnect: ', data);
});

// Reconnect successful
client.on('reconnected', (data) => {
  console.log('reconnected: ', data);
});

// Connection closed. If unexpected, expect reconnect -> reconnected.
client.on('close', (data) => {
  console.error('close: ', data);
});

// Reply to a request, e.g. "subscribe"/"unsubscribe"/"authenticate"
client.on('response', (data) => {
  console.info('response: ', JSON.stringify(data, null, 2));
  // throw new Error('res?');
});

client.on('exception', (data) => {
  console.error('exception: ', data);
});

/**
 * Use the client subscribe(topic, market) pattern to subscribe to any websocket topic.
 *
 * You can subscribe to topics one at a time or many in one request.
 *
 * Topics can be sent as simple strings, if no parameters are required:
 */

// market data
client.subscribe('heartbeats', 'advTradeMarketData');
// This is the same as above, but using WS_KEY_MAP like an enum to reduce any uncertainty on what value to use:
// client.subscribe('heartbeats', WS_KEY_MAP.advTradeMarketData);

// user data
client.subscribe('futures_balance_summary', 'advTradeUserData');
client.subscribe('user', 'advTradeUserData');

/**
 * Or send a more structured object with parameters, e.g. if parameters are required
 */
const tickerSubscribeRequest = {
  topic: 'ticker',
  /**
   * Anything in the payload will be merged into the subscribe "request",
   * allowing you to send misc parameters supported by the exchange (such as `product_ids: string[]`)
   */
  payload: {
    product_ids: ['ETH-USD', 'BTC-USD'],
  },
};
client.subscribe(tickerSubscribeRequest, 'advTradeMarketData');

/**
 * Other adv trade public websocket topics:
 */
client.subscribe(
  [
    {
      topic: 'candles',
      payload: {
        product_ids: ['ETH-USD'],
      },
    },
    {
      topic: 'market_trades',
      payload: {
        product_ids: ['ETH-USD', 'BTC-USD'],
      },
    },
    {
      topic: 'ticker',
      payload: {
        product_ids: ['ETH-USD', 'BTC-USD'],
      },
    },
    {
      topic: 'ticker_batch',
      payload: {
        product_ids: ['ETH-USD', 'BTC-USD'],
      },
    },
    {
      topic: 'level2',
      payload: {
        product_ids: ['ETH-USD', 'BTC-USD'],
      },
    },
  ],
  'advTradeMarketData',
);

See WebsocketClient for further information and make sure to check the examples folder for much more usage examples, especially publicWs.ts and privateWs.ts, which explains a lot of small details.

Customise Logging

Pass a custom logger which supports the log methods trace, info and error, or override methods from the default logger as desired.

const { WebsocketClient, DefaultLogger } = require('coinbase-api');
/**
 * Or, with import:
 * import { WebsocketClient, DefaultLogger } from 'coinbase-api';
 */

// E.g. customise logging for only the trace level:
const logger = {
  // Inherit existing logger methods, using an object spread
  ...DefaultLogger,
  // Define a custom trace function to override only that function
  trace: (...params) => {
    if (
      [
        'Sending ping',
        'Sending upstream ws message: ',
        'Received pong, clearing pong timer',
        'Received ping, sending pong frame',
      ].includes(params[0])
    ) {
      return;
    }
    console.log('trace', params);
  },
};

const ws = new WebsocketClient(
  {
    apiKey: 'apiKeyHere',
    apiSecret: 'apiSecretHere',
    apiPassphrase: 'apiPassPhraseHere',
  },
  logger,
);
