    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+https://github.com/bitcapital-hq/bitcapital-core-sdk.git#1.3.0";

    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 https://bitcapital.com.br/developers.

    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: 'https://your-instance.btcore.app',
      // 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: 'user@example.com',
        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

    Library Reference

    Full API specification is located at: https://sdk.btcore.app.

    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> {
        this.data[key] = value;
        return value;
      async getItem(key: string): Promise<any> {
        return this.data[key];
      async removeItem(key: string): Promise<void> {
        delete this.data[key];
      async clear(): Promise<void> {
        this.data = {};
