🚀 Key Features

• Decorator-Driven Resource Management: Use decorators to intuitively define and manage resources, resulting in cleaner, more expressive code.
• Modular Architecture: Treat every component as a resource, promoting reusability and better organization of application logic.
• Extensible Framework: Effortlessly extend core functionalities by adding custom field types, decorators, and plugins tailored to specific project needs.
• Customizable Field Types: Support for various built-in field types (such as number, dropdown, selectResource) that can be customized with specific properties for flexible data handling.
• Type Safety: Developed with TypeScript, ensuring robust type-checking for a reliable foundation for scalable applications.
• Intuitive API: Enjoy a developer-friendly API that leverages TypeScript features for smooth auto-completion and type hints.
• Dynamic Ecosystem: Easily adapt to evolving project requirements by integrating external decorators and features, allowing for a responsive and flexible development environment.

⚙️ Getting Started

To begin using ResKit, follow these steps:

1. Prerequisites

Make sure you have the following installed on your machine:

• Node.js (version 14 or higher)
• npm (Node Package Manager)

2. 🛠️ Install Required Packages

To set up ResKit, you'll need to install the necessary packages. Run the following command:

npm install @resk reflect-metadata
# or
yarn add @resk reflect-metadata

Also, install the necessary TypeScript dev dependencies:

npm install --save-dev typescript @types/node # or yarn add -D typescript @types/node

3. TypeScript Configuration

Create a tsconfig.json file in your project root with the following configuration:

{
    "compilerOptions": {
      "esModuleInterop": true,
      "forceConsistentCasingInFileNames": true,
      "target": "es6",                          // Use ES6 or higher
      "module": "commonjs",                     // Use commonjs module system
      "experimentalDecorators": true,           // Enable experimental support for decorators
      "emitDecoratorMetadata": true,             // Enable emitting design:type metadata
      "strict": true,                            // Enable all strict type checking options
      "skipLibCheck": true                       // Skip type checking of declaration files
    },
    "include": ["src/**/*"],
    "exclude": ["node_modules"]
}

4. Import reflect-metadata

In your entry file (usually index.ts or app.ts), ensure that you import reflect-metadata at the very top of the file. This is required to enable metadata reflection for decorators.

import "reflect-metadata";

📚 Documentation

Resources

• Resources are the foundation of ResKit. Use the @Resource decorator to define any logical entity (models, components, etc.).
• Fields: Add fields to your resources using the @Field decorator, specifying field types and options.

Built-In Field Types

• number: Simple number field.
• string: Simple string field;
• boolean: Simple boolean field;
• symbol : Simple symbol field;
• switch : Can be a number of a boolean;
• checkbox: Can be a number of a boolean;

Once you have installed the necessary packages and set up TypeScript, you can start defining resources and fields using ResKit decorators.

Basic Example

import "reflect-metadata";
import { Resource, Field } from "@resk";

@Resource()
class User {
  @Field({ type: "string" })
  name: string;

  @Field({ type: "number" })
  age: number;

  @Field({ type: "email" })
  email: string;
}

Examples

Defining Custom Field Types

@Field({ type: 'dropdown', options: ['Admin', 'User', 'Guest'] })
role: string;

@Field({ type: 'selectResource', resourceName: 'Product' })
favoriteProduct: string;

Creating Extensible Decorators

You can easily create and register new decorators to extend the functionality of your resources.

function CustomField(options: { customProp: string }) {
  return function (target: any, propertyKey: string) {
    // Custom decorator logic
    Reflect.defineMetadata("customProp", options.customProp, target, propertyKey);
  };
}

Advanced Examples

🔄 Extending the Framework

ResKit is designed for flexibility. You can add your own custom field types or extend existing ones with full TypeScript support.

Extending Field Types

You can easily extend the field types available in ResKit by creating custom decorators. To extend field types and register custom options (e.g., a rating field), use TypeScript's declaration merging.

function ExtendedField(type: string, options: any) {
    return function (target: any, propertyKey: string) {
        Reflect.defineMetadata('design:type', type, target, propertyKey);
        Reflect.defineMetadata('field:options', options, target, propertyKey);
    };
}

// Define a new field type for a color picker
@ExtendedField('colorPicker', { defaultColor: '#000000' })
color: string;

This allows ResKit to recognize new custom field types, complete with IntelliSense support.

Adding New Resources

You can create new resources and leverage the existing decorators for rich resource definitions.

@Resource()
class Product {
  @Field({ type: "string" })
  productName: string;

  @Field({ type: "number" })
  price: number;

  @Field({ type: "string", options: { enum: ["In Stock", "Out of Stock"] } })
  availability: string;
}

Custom Decorator for Advanced Logic

You can also create custom decorators that implement advanced logic, such as validation or transformation.

function IsPositive(target: any, propertyKey: string) {
    const value = target[propertyKey];
    if (value < 0) {
        throw new Error(`${propertyKey} must be a positive number.`);
    }
}

@Resource()
class Order {
    @Field({ type: 'number' })
    @IsPositive
    totalAmount: number;

    @Field({ type: 'string' })
    customerName: string;
}

Using Extended Field Types

Here’s how you can use the newly defined field types in a resource:

@Resource()
class EnhancedUser {
  @Field({ type: "string" })
  name: string;

  @ExtendedField("colorPicker", { defaultColor: "#FF0000" })
  favoriteColor: string;
}

🔌 Plugins & Extensions

ResKit can be extended with plugins and custom modules. Define new decorators, extend resource behavior, and add complex validation logic as needed.

Example: Custom Decorator Plugin

import { Resource, Field, customDecorator } from '@resk';

function LogField() {
  return customDecorator((target, key) => {
    console.log(`Field '${key}' has been initialized.`);
  });
}

@Resource
class Product {
  @LogField()
  @Field({ type: "number" })
  price: number;
}
