##### Importing the package as an external script in the HTML code

It is possible to include a compiled version of the package directly in an HTML file. It will create a global isometric object that can be accessed from anywhere in your JavaScript code.

Copy the JavaScript file isometric.js, located in the dist/web folder
Put it in the folder that you prefer in your web server
Include it in your HTML file

<script src="wherever/you/installed/isometric.js"></script>

/ There will be a global variable named isometric containing all the classes /
isometric.IsometricCanvas;
isometric.IsometricGroup;
isometric.IsometricRectangle;
isometric.IsometricCircle;
isometric.IsometricStarPolygon;
isometric.IsometricPentagram;
isometric.IsometricPath;

##### Importing the package in your code using CommonJS

const {
    IsometricCanvas,
    IsometricGroup,
    IsometricRectangle,
    IsometricCircle,
    IsometricStarPolygon,
    IsometricPentagram,
    IsometricPath
} = require('@elchininet/isometric');

##### Importing the package in your code using ES6 modules

import {
    IsometricCanvas,
    IsometricGroup,
    IsometricRectangle,
    IsometricCircle,
    IsometricStarPolygon,
    IsometricPentagram,
    IsometricPath
} from '@elchininet/isometric';

In node environments

To use the package in a Node environment, you need to install jsdom because the package needs it to work properly.

##### Importing the package in your code using CommonJS

const {
    IsometricCanvas,
    IsometricGroup,
    IsometricRectangle,
    IsometricCircle,
    IsometricStarPolygon,
    IsometricPentagram,
    IsometricPath

} from '@elchininet/isometric/node';

In Deno

To import the package in Deno, use the main esm version using any content delivery as UNPKG or JSDELIVR. The package contains a reference directive to the d.ts file so you can get type checking importing it without doing anything special.

import {
    IsometricCanvas,
    IsometricGroup,
    IsometricRectangle,
    IsometricCircle,
