@encolajs/hydrator

🚀 A powerful, flexible data transformation library that makes type casting, object hydration, and collections management a breeze! Built with TypeScript and designed with developer experience in mind.

Why EncolaJS Hydrator?

• ✨ Seamless Type Casting: Convert values between types automatically
• 🌳 Model Hydration: Transform plain objects into rich class instances
• 🔄 Smart Collections: Filter, sort, group, and aggregate with a fluent API
• 🏗️ Extensible Architecture: Create custom casters and mixins
• 🌍 Framework Agnostic: Use with any JavaScript project
• 🪶 Modular: Use components together or independently

Quick Start

npm install @encola/hydrator

Simple Example

import { CastingManager, ClassBuilder } from '@encola/hydrator';

// Setup core components
const castingManager = new CastingManager();
const builder = new ClassBuilder(castingManager);

// Create a model class
const User = builder.newModelClass({
  id: 'number',
  name: 'string',
  email: 'string',
  lastLogin: 'date'
});

// Create a collection class
const UserCollection = builder.newCollectionClass(User);

// Register for easy hydration
castingManager.registerModel('user', User, UserCollection);

// Use in your application
async function fetchUsers() {
  const response = await fetch('/api/users');
  const data = await response.json();
  // Automatically converts to User instances in a UserCollection
  return castingManager.cast(data, 'userCollection');
}

Core Features

CastingManager

Intelligent type conversion with built-in and custom casters:

castingManager.cast('123', 'number'); // 123
castingManager.cast('2023-01-15', 'date'); // Date object
castingManager.cast(['1', '2'], 'array:number'); // [1, 2]

BaseModel

Build structured data models with automatic serialization:

const product = new Product({
  name: 'Laptop',
  price: '1299.99', // Automatically converted to number
  inStock: 'true'   // Automatically converted to boolean
});

console.log(product.toJSON()); // Serialized for server API

BaseCollection

Supercharged arrays with powerful data operations:

const electronics = products.filterBy('category', 'electronics');
const expensive = products.filterBy(p => p.price > 1000);
const byPrice = products.sortBy('price', 'desc');
const total = products.sum('price');
const grouped = products.groupBy('category');
