A multi-platform SDK for accessing the Bitcapital Core services in JS and TS environments.

Getting started (From GitHub)

Install as a project dependency using Yarn, remember to specify the desired version.

yarn add "github:bitcapital-hq/bitcapital-core-sdk#1.3.0";

Or use NPM:

npm install "git+";

Getting started (From source)

Install the dependencies and make sure everything is OK by running the automated tests.

yarn install
yarn test

Prepare the changes for publishing using the Typescript compiler

yarn run build

Configuring your Client

To start using this SDK you need both a Client ID and a Client Secret, emitted by the Bitcapital Core Team. If you don't have yours yet, contact them at

Configure your Bitcapital SDK instance.

import Bitcapital from 'bitcapital-core-sdk';

// Initialize the session instance to authenticate
// using the Bitcapital Core OAuth 2.0 provider.
const bitcapital = Bitcapital.initialize({
  // Instance URL for REST API calls
  baseURL: '',
  // Credentials for OAuth 2.0 requests
  clientId: '< YOUR CLIENT_ID HERE >',
  clientSecret: '< YOUR CLIENT_SECRET HERE >',

try {
  // Authenticate a user with email and password from Bitcapital Core
  // If succeeds and available, the credentials will be stored in the 
  // session instance and in the local storage (for browser environments).
  const user = await bitcapital.session().password({
    email: '',
    password: '12345678',

  // The session returns the user info and credentials

  // To logout and clear the current credentials, use the "destroy" action
  await bitcapital.session().destroy();

} catch(exception) {
  // Something went wront, probably credentials are invalid

Accessing library modules

Library modules:

  • bitcapital.assets(): Handles asset creation, emition and destruction.
  • bitcapital.consumers(): Creates, updates, validates and deactivates consumer accounts.
  • Creates, updates and removes domains from the network.
  • bitcapital.payments(): Send payments between wallets and access its history.
  • bitcapital.users(): Manages user accounts in the network.
  • bitcapital.wallets(): Creates, updates and deactivates wallets in the network.

Internal Modules:

  • bitcapital.session(): Manages credentials in the SDK.
  • bitcapital.oauth(): Manages authentication in the Bitcapital OAuth 2.0 provider.

Utility Modules:

  • bitcapital.sign(): Handles requests signature. Automatically called in required API requests.

Using a Custom Session

The SDK comes with a built-in set of Storage providers: Memory and Local. In NodeJS environments, only Memory is available.

To override the default storage for your platform, pass it in the Session constructor:

// Initialize a custom session with desired storage
const session = Session.initialize({
  storage: new StorageUtil('session', new MemoryStorage()),
  oauth: {
    baseURL: data.baseURL,
    clientId: data.clientId,
    clientSecret: data.clientSecret,
  http: {
    baseURL: data.baseURL,
    clientId: data.clientId,
    clientSecret: data.clientSecret,

// Initialize bitcapital service with specified credentials
const bitcapital = Bitcapital.initialize({
  // Pass your custom session instance
  // Other initialization configs...
  baseURL: data.baseURL,
  clientId: data.clientId,
  clientSecret: data.clientSecret,

Creating a custom Storage provider

To implement another Storage mechanism, extend the StorageUtilEngine interface.

import { StorageUtilEngine } from "bitcapital-core-sdk";

export default class MemoryStorage implements StorageUtilEngine {
  protected data: any = {};

  async setItem(key: string, value: string): Promise<any> {[key] = value;
    return value;
  async getItem(key: string): Promise<any> {
  async removeItem(key: string): Promise<void> {
  async clear(): Promise<void> { = {};
