@hsuite/auth - Authentication Module

🔐 Comprehensive NestJS authentication module providing unified Web2 & Web3 authentication solutions

A robust, enterprise-grade authentication module that seamlessly integrates traditional username/password authentication with cutting-edge Web3 wallet-based authentication, designed specifically for the HSuite ecosystem.

Quick Start

Installation

npm install @hsuite/auth

Basic Setup

import { AuthModule } from '@hsuite/auth';

@Module({
  imports: [
    AuthModule.forRootAsync({
      useFactory: () => ({
        commonOptions: {
          jwt: { secret: 'your-secret', signOptions: { expiresIn: '24h' } },
          passport: IAuth.IConfiguration.IPassportStrategy.JWT
        },
        web2Options: { confirmation_required: true },
        web3Options: { tokenGateOptions: {} }
      })
    })
  ]
})
export class AppModule {}

Protect Your Routes

@UseGuards(JwtAuthGuard)
@Get('protected')
getProtected(@Request() req) {
  return { user: req.user };
}

Architecture

Core Components

🛡️ Guards

JwtAuthGuard - JWT-based route protection
RedisAuthGuard - Redis session authentication
ConfirmedAuthGuard - Email confirmation requirement

🌐 Strategies

JwtStrategy - Passport JWT strategy implementation
RedisStrategy - Redis-based session strategy
Web3Strategy - Blockchain wallet authentication

🔧 Services

AuthService - Core authentication logic
AuthController - REST API endpoints

API Reference

AuthModule

Static Methods

forRootAsync(options: AuthModuleAsyncOptions): DynamicModule

Configures the authentication module with async dependency injection.

interface AuthModuleAsyncOptions {
  imports?: any[];
  useFactory?: (...args: any[]) => Promise<IAuth.IConfiguration.IAuthentication>;
  inject?: any[];
  config?: {
    passport: IAuth.IConfiguration.IPassportStrategy;
    module: 'web2' | 'web3';
    options: IAuth.IConfiguration.IOptions;
  };
}

AuthService

Core Methods

validateUser(username: string, password: string): Promise<any>

Validates user credentials for Web2 authentication

login(user: any): Promise<{ access_token: string }>

Generates JWT token for authenticated user

register(userData: CreateUserDto): Promise<User>

Registers new user with email confirmation

Guards Reference

JwtAuthGuard

@UseGuards(JwtAuthGuard)
@Get('jwt-protected')
jwtProtected(@Request() req) {
  return { user: req.user };
}

RedisAuthGuard

@UseGuards(RedisAuthGuard)
@Get('session-protected')
sessionProtected(@Request() req) {
  return { session: req.session };
}

ConfirmedAuthGuard

@UseGuards(JwtAuthGuard, ConfirmedAuthGuard)
@Post('confirmed-only')
confirmedOnly(@Request() req) {
  return { message: 'Email confirmed user only' };
}

Guides

Web2 Authentication Guide

Learn how to implement traditional username/password authentication with email confirmation and 2FA. Configure user registration, login flows, password reset, and session management.

Web3 Authentication Guide

Implement blockchain wallet-based authentication with signature verification and token gating. Set up wallet connection, signature validation, and decentralized identity management.

Session Management Guide

Configure Redis-based session management for distributed applications. Implement session storage, expiration policies, and cross-service session sharing.

Guards & Strategies Guide

Deep dive into authentication guards and Passport strategies. Create custom guards, implement authorization logic, and manage authentication flows.
