Snake Render Engine

Snake Render Engine is a 2D render engine which wraps WebGL with a functional API, analogous to the well-known React UI library. It also supports JSX syntax and is Component based.

Here is a minimal example that highlights how to run it:

// In order to define components we need to import SRE
import SRE, { initRenderer, initWithRenderer, Rect } from "snake-render-engine";

// Get the host canvas where the engine will run
const canvas = document.getElementById("canvas");
const height = canvas.height;
const width = canvas.width;

const gl = canvas.getContext("webgl");

const render = initRenderer({ gl, width, height });
const run = initWithRenderer(canvas, render);

// Define a Scene Node that renders a simple rect and logs click events
const Scene = () => (
  <Rect x={320} y={200} z={0} width={640} height={100} onClick={console.log} />
);

// Start it
run(<Scene />);
