Nested

Provides nesting capabilities to classes allowing you to create deeply nested object structures, while also enabling you to traverse them efficiently.

Features

• Simple API for creating nested object hierarchies.
• Built-in .root property for accessing the root of the hierarchy.
• .sub() method for creating sub-nodes.

Installation

npm install @basd/nested

Usage

Import the Nested class mixin from the package:

import Nested from '@basd/nested'

or

const Nested = require('@basd/nested')

Create a nested instance

const nested = new Nested()

Extend your own class with the Nested mixin:

class MyClass extends Nested {
  // Your implementation here
}

const root = new MyClass()

Create a Nested Object

const nodeA = root.sub('nodeA')
const nodeB = nodeA.sub('nodeB')

Access Parent and Root Nodes

console.log(nodeB.parent === nodeA) // true
console.log(nodeB.root === root)    // true

Dynamic Options

You can use a function as options to sub():

const dynamicNode = root.sub('dynamic', (node, part) => ({
  someOption: `${node.someOption}/${part}`
}))

Documentation

• API Reference

Nested.mixin(childClass)

Mix the Nested functionality into a childClass.

root()

Returns the root node of the current hierarchy.

sub(path, opts, ...args)

Creates a sub-node at the specified path. You can optionally pass a custom opts object or a function for dynamic configuration.
