The extension sometimes entails its personal distinct methodology of set up. This can be by way of direct file inclusion in your HTML or utilizing a bundle supervisor reminiscent of npm or yarn. As soon as arrange, you will have entry to the extension’s features inside your JavaScript code.

Code Instance

For example, you may have a easy perform to attract a polygon:

// Assuming a library title of "shapeUtils" and canvas id of "myCanvas"

const canvas = doc.getElementById("myCanvas");
const ctx = canvas.getContext("second");

// instance polygon factors
const polygonPoints = [
    { x: 50, y: 50 },
    { x: 150, y: 50 },
    { x: 200, y: 150 },
    { x: 100, y: 200 },
];

shapeUtils.drawPolygon(ctx, polygonPoints, "pink", "blue", 2); // Instance parameters

This instance reveals the simplicity this sort of extension can deliver. The usual methodology, whereas versatile, would require you to loop by way of the factors, use `beginPath()`, `moveTo()`, `lineTo()`, `closePath()`, and eventually `stroke()` or `fill()`.

perform drawCircle() {
    ctx.clearRect(0, 0, canvas.width, canvas.top);
    ctx.beginPath();
    ctx.arc(circle.x, circle.y, circle.radius, 0, 2 * Math.PI);
    ctx.fillStyle = circle.shade;
    ctx.fill();
}

canvas.addEventListener("mousemove", (occasion) => {
    const rect = canvas.getBoundingClientRect();
    const mouseX = occasion.clientX - rect.left;
    const mouseY = occasion.clientY - rect.high;

    if (
        Math.sqrt((mouseX - circle.x) ** 2 + (mouseY - circle.y) ** 2) <
        circle.radius
    ) {
        circle.shade = "pink";
    } else {
        circle.shade = "inexperienced";
    }
    drawCircle();
});

// The usual method to easy interactivity is extra tedious
