A small utility library for making and working with grids.

Installation

1. npm install nko-grid
2. import Grid from 'nko-grid'
3. See docs below for usage.

Usage

Declare a new NKOGrid(), which takes the following parameters in the form of an object:

{
	width: 250 // Default: 100
	height: 250 // Default: 100
	centerX: 125 // Default: 0
	centerY: 125 // Default: 0
	numX: 20 // Default: 10
	numY: 20 // Default: 10
}

This will create an instance of the NKOGrid, with the field yourGrid.nodes populated with an Array of objects, each having the following properties:

	yourNode.x // x position on the canvas
	yourNode.y // y position on the canvas
	yourNode.iX // column of the node
	yourNode.iY // row of the node
	yourNode.data // empty object, can be replaced by custom data, or instances of objects.

The NKOGrid instance has two methods:

• yourGrid.getNode(column, row): returns a node object.
• yourGrid.getNodeSafe(column, row): will throw a RangeError if selection is out of bounds.
