quinton-ashley/native-canvas

A canvas library that allows for a HTML canvas to run natively on NodeJs, without a WebBrowser

native-canvas

Overview

The purpose and intent of this project was to create a library that allows for developers to create a browser canvas element that runs natively, without the need of a WebBrowser. Allowing for developers to code and develop portable canvas based applications that can run both on the WebBrowser and natively on any NodeJS platform.

Requirements

• NodeJS 10+

Getting Stated

• Install the native-canvas library

npm install native-canvas

A Simple Example

// Load the library
require('native-canvas');

// Use the globally exposed canvas
const ctx = canvas.getContext("2d");

ctx.lineWidth = 1;
ctx.fillStyle = "#FF0000";
ctx.fillRect(0, 0, 150, 75);

Running a Browser Example

// Load the library
require('native-canvas');

// Title the title attribute
document.title = 'Create Canvas with Document';

// Provides the current running canvas
const canvas = document.createElement('canvas');
const ctx = canvas.getContext("2d");

canvas.height = 150;

ctx.lineWidth = 1;

ctx.clearRect(0, 0, 400, 400);
ctx.beginPath();
ctx.arc(40, 40, 40, 0, 2 * Math.PI);
ctx.closePath();
ctx.stroke();
