@hsuite/smartnode-sdk

A powerful SDK for interacting with SmartNode services and Hedera Hashgraph network functionality. This SDK provides a comprehensive set of tools and interfaces for managing SmartNode operations, validator interactions, and Hedera Hashgraph services.

Features

• SmartNode Operations: Core functionality for interacting with SmartNode services

• Validator Management: Tools for managing and interacting with validators

• Hedera Hashgraph Integration:

  • Hashgraph Consensus Service (HCS) operations

  • Account management

  • Transaction handling

  • Token Service (HTS) operations

Installation

npm install @hsuite/smartnode-sdk

Module Integration

The SDK is designed to be integrated into NestJS applications using the module system. It provides flexible configuration options through asynchronous initialization.

Basic Usage

import { SmartNodeSdkModule } from '@hsuite/smartnode-sdk';
import { ConfigModule, ConfigService } from '@nestjs/config';

@Module({
  imports: [
    SmartNodeSdkModule.forRootAsync({
      imports: [ConfigModule],
      useFactory: async (configService: ConfigService) => ({
        client: {
          // Your client configuration
        }
      }),
      inject: [ConfigService]
    })
  ]
})
export class AppModule {}

Services

SmartNodeSdkService

The main service that provides access to all SDK functionality. It initializes and manages the following sub-services:

• smartNodeRestful: Core SmartNode operations

• validatorsRestful: Validator management operations

• hcsHashgraphRestful: Hedera Consensus Service operations

• accountsHashgraphRestful: Hedera account management

• transactionsHashgraphRestful: Transaction handling

• htsHashgraphRestful: Hedera Token Service operations

REST Services

Base Restful Service

All REST services extend from a base implementation that provides common functionality for HTTP requests and error handling.

Available Services

1. SmartNode Restful

   • Core SmartNode operations and management

2. Validators Restful

   • Validator management and interaction

3. HCS (Hashgraph Consensus Service) Restful

   • Consensus service operations

   • Message submission and retrieval

4. Accounts Hashgraph Restful

   • Account creation and management

   • Balance queries

   • Account updates

5. Transactions Hashgraph Restful

   • Transaction submission

   • Transaction status queries

   • Transaction history

6. HTS (Hedera Token Service) Restful

   • Token creation and management

   • Token transfers

   • Token information queries

Configuration

The SDK supports flexible configuration through the SmartNodeSdkModuleAsyncOptions interface:

interface SmartNodeSdkModuleAsyncOptions {
  imports?: Array<any>;
  useExisting?: Array<Type<any>>;
  useClass?: Type<any>;
  useFactory?: (...args: any[]) => Promise<ISdk.IOptions> | ISdk.IOptions;
  inject?: any[];
}

Configuration Options

The SDK can be configured using three different patterns:

1. Using an existing factory

2. Creating a new factory class

3. Using a factory function

Dependencies

• @nestjs/common

• @hsuite/client
