Codex

A flexible and robust package that provides a system for managing models, fields, and their validations. Designed to be highly extensible, it provides a solid structure for working with different types of data structures.

Features

• Define and manage complex data models.
• Field validation for models.
• Extendable with custom fields.
• Supports foreign keys and relationships.
• Easy integration with other systems.

Installation

Install the package with:

npm install @basd/codex

Usage

First, import the Codex library.

import Codex from '@basd/codex'

or

const Codex = require('@basd/codex')

Defining Models

const codex = new Codex({
  user: {
    name: '*string', // * makes it required (default)
    age: 'number',
    friend: '~user' // ~ makes it optional
  }
})

const userModel = codex.getModel('user')
const userInstance = userModel.create({ name: 'John', age: 30 })

The above example defines a user model with a name, age, and an optional recursive friend relationship.

Field Validation

Fields are automatically validated upon creation:

const invalidUser = userModel.create({ name: 123, age: 'thirty' })  // This will throw an error

Or you can manually validate:

const isValid = codex.valid('user', { username: 'JohnDoe', age: 'twenty five' }) // returns false

Using Custom Fields

class CustomField extends Field {
  // Custom implementation
}
// Add to registry (assuming registry instance is available)
registry.set('field.custom', CustomField)

const customModel = new Model({
  customField: 'custom'
})

Extending Field Types

The library is designed with extensibility in mind. You can easily extend built-in field types or create your own.

For example, to extend the StringField:

class CapitalizedStringField extends StringField {
  _create(value) {
    const strValue = super._create(value)
    return strValue.charAt(0).toUpperCase() + strValue.slice(1)
  }
}

Documentation

• API Reference

API Reference

• Field: The base class for all field types.
• StringField, NumberField, ForeignField: Field types provided by default.
• Model: Class to define and manage data models.
• Factory: A helper class to create models and fields.
• Codex: Main entry point to define and manage the whole system.

For each class and method, refer to the code documentation for detailed usage.

Extending

You can extend default classes to introduce custom behavior or implement additional field types. Use the Factory class to register and manage custom implementations.

Error Handling

The library comes with a predefined set of error messages that are thrown when validation fails. You can easily capture these and handle them in your application.

Tests

In order to run the test suite, simply clone the repository and install its dependencies:
