Contact Service Library

The Contact Service Library provides a robust interface for managing contacts associated with Decentralized Identifiers (DIDs) using IndexedDB. This library allows you to create, retrieve, update, and delete contacts efficiently and utilizes a well-defined database schema.

Installation

To install the Contact Service Library, use the command below.

npm install @adorsys-gis/contact-service

Contact Model

The library defines a interface outlining the structure of a contact object.

export interface Contact {
  id: number;
  name: string;
  did: string;
}

Usage Example

import { EventEmitter } from 'eventemitter3';
import { ContactService } from '@adorsys-gis/contact-service';

const eventBus = new EventEmitter();
const contactService = new ContactService(eventBus);

// Listen for the contact creation event
eventBus.on('contact-created', (response) => {
  if (response.status == ServiceResponse.Success) {
    const createdContact = response.payload;
    console.log('Contact created successfully:', createdContact);
  } else {
    const error = response.payload;
    console.error('Failed to create contact:', error);
  }
});

// Create a new contact (no need to include 'id', as it will be generated)
contactService.createContact({
  name: 'John Doe',
  did: 'did:example:123456',
});
