📚 Table of Contents

✨ Quick Start

Installation

npm install @hsuite/subscriptions-types

Basic Setup

import { ISubscription, Subscription } from '@hsuite/subscriptions-types';

// Interface-based type definitions
const plan: ISubscription.IPlan = ISubscription.IPlan.PREMIUM;
const status: ISubscription.IStatus = ISubscription.IStatus.ACTIVE;
const period: ISubscription.IPeriodicity = ISubscription.IPeriodicity.MONTHLY;

// Model-based runtime validation
const subscription = new Subscription.Web3.Entity();
const payment = new Subscription.Web3.Payment.Entity();
const analytics = new Subscription.Web3.Analytics.Entity();

NestJS Integration

import { Subscription } from '@hsuite/subscriptions-types';

@Controller('subscriptions')
export class SubscriptionController {
  @Post('create')
  @ApiResponse({ type: Subscription.Web3.Entity })
  async createSubscription(@Body() data: any): Promise<Subscription.Web3.Entity> {
    return new Subscription.Web3.Entity(data);
  }
}
