@rubriqflow/core

Business logic and utilities for RubriqFlow applications.

🎯 Purpose

This package provides shared business logic implementations that can be used across v2 and FileDrop applications. It contains database-agnostic utilities, validation logic, and common functionality.

✨ Key Features

• 🔐 Password Validation: Comprehensive password strength validation with FileDrop requirements
• 📧 Email Validation: Email format validation and darkware domain detection
• 🔑 Access Code Generation: 6-character alphanumeric codes for FileDrop portfolios
• 🆔 ID Generation: Unique ID generation for users, organizations, portfolios, and files
• 🧪 100% Test Coverage: Comprehensive test suite with TDD approach
• 📚 Full Documentation: TSDoc comments for all functions

📦 Installation

npm install @rubriqflow/core
# or
yarn add @rubriqflow/core
# or
pnpm add @rubriqflow/core

🚀 Quick Start

import { PasswordValidator, EmailValidator } from '@rubriqflow/core';

// Password validation
const passwordValidator = new PasswordValidator();
const result = passwordValidator.validatePasswordStrength('Password123');
console.log(result.isValid); // true
console.log(result.score); // 100

// Email validation
const emailValidator = new EmailValidator();
const isValid = emailValidator.validateEmail('[email protected]');
console.log(isValid); // true

// Darkware email detection (for testing)
const isDarkware = emailValidator.isDarkwareEmail('[email protected]');
console.log(isDarkware); // true

// Access code generation
const accessCode = passwordValidator.generateAccessCode();
console.log(accessCode); // "ABC123"

📋 Available Utilities

🔐 PasswordValidator

Comprehensive password validation and hashing utilities.

import { PasswordValidator } from '@rubriqflow/core';

const validator = new PasswordValidator();

// Validate password strength
const result = validator.validatePasswordStrength('Password123');
// Returns: { isValid: boolean, score: number, feedback: string[], requirements: {...} }

// Hash password
const hash = await validator.hashPassword('Password123');

// Verify password
const isValid = await validator.verifyPassword('Password123', hash);

// Generate access codes
const code = validator.generateAccessCode(); // "ABC123"
const isValidCode = validator.validateAccessCode('ABC123'); // true

// Generate unique IDs
const userId = validator.generateUserId(); // "user_1234567890_abc123"
const orgId = validator.generateOrganizationId(); // "org_1234567890_abc123"

Password Requirements:

• Minimum 10 characters
• At least 1 number
• At least 1 uppercase letter
• At least 1 lowercase letter

📧 EmailValidator

Email validation and normalization utilities.

import { EmailValidator } from '@rubriqflow/core';

const validator = new EmailValidator();

// Validate email format
const isValid = validator.validateEmail('[email protected]');

// Check for darkware domain (testing)
const isDarkware = validator.isDarkwareEmail('[email protected]');

// Extract domain
const domain = validator.extractDomain('[email protected]'); // "example.com"

// Normalize email
const normalized = validator.normalizeEmail('[email protected]'); // "[email protected]"

// Comprehensive validation for registration
const result = validator.validateEmailForRegistration('[email protected]');
// Returns: { isValid: boolean, isDarkware: boolean, normalizedEmail: string, domain: string | null }

// Token generation and validation
const verifyToken = validator.generateEmailVerificationToken();
const resetToken = validator.generatePasswordResetToken();
const isExpired = validator.isTokenExpired(token);

🏗️ Architecture

The core library follows these principles:

1. Database Agnostic

All utilities work without database dependencies, making them reusable across different storage backends.

2. Pure Functions

Most functions are pure and stateless, making them easy to test and reason about.

3. Error Handling

Comprehensive error handling with meaningful error messages.

4. Type Safety

Full TypeScript support with strict type checking.

🔄 Versioning

• MINOR (1.0.0 → 1.1.0): New features, backward compatible
• PATCH (1.0.0 → 1.0.1): Bug fixes, backward compatible

🏢 Usage in Applications

RubriqFlow v2

// v2/lib/implementations/services/AuthService.ts
import { PasswordValidator, EmailValidator } from '@rubriqflow/core';

export class AuthService implements IAuthService {
  private passwordValidator = new PasswordValidator();
  private emailValidator = new EmailValidator();

  async validatePasswordStrength(password: string) {
    return this.passwordValidator.validatePasswordStrength(password);
  }

  async hashPassword(password: string) {
    return this.passwordValidator.hashPassword(password);
  }
}

FileDrop MVP

// filedrop/lib/implementations/services/FileDropService.ts
import { PasswordValidator, EmailValidator } from '@rubriqflow/core';

export class FileDropService implements IFileDropService {
  private passwordValidator = new PasswordValidator();
  private emailValidator = new EmailValidator();

  generateAccessCode() {
    return this.passwordValidator.generateAccessCode();
  }

  validateEmail(email: string) {
    return this.emailValidator.validateEmail(email);
  }
}
