Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Vector2D Library for TypeScript

A comprehensive TypeScript library for 2D vector operations, including addition, subtraction, multiplication, division, normalization, and more. Ideal for game development, physics simulations, and graphical applications.

Features

  • Create and manipulate 2D vectors
  • Perform vector arithmetic (addition, subtraction, multiplication, division)
  • Calculate dot and cross products
  • Normalize vectors
  • Calculate magnitude and distance between vectors
  • Rotate vectors
  • Linear interpolation between vectors

Installation

You can install the library using npm:

npm install ts-vector2d

Usage

Here's a quick example of how to use the Vector2D class:

import { Vector2D } from 'vector2d';

const vector1 = new Vector2D(3, 4);
const vector2 = new Vector2D(1, 2);

// Vector addition
const result = vector1.add(vector2);
console.log(`Result of addition: (${result.getX()}, ${result.getY()})`);

// Vector normalization
const normalized = vector1.normalize();
console.log(`Normalized vector: (${normalized.getX()}, ${normalized.getY()})`);

API Reference

Vector2D

Constructor

constructor(x: number, y: number)
x - The x-coordinate.
y - The y-coordinate.

Methods

  • getX(): number - Gets the x-coordinate.
  • getY(): number - Gets the y-coordinate.
  • setX(x: number): void - Sets the x-coordinate.
  • setY(y: number): void - Sets the y-coordinate.
  • set(x: number, y: number): void - Sets both the x and y coordinates.
  • add(vector: Vector2D): Vector2D - Adds another vector to this vector.
  • subtract(vector: Vector2D): Vector2D - Subtracts another vector from this vector.
  • multiply(scalar: number): Vector2D - Multiplies this vector by a scalar.
  • divide(scalar: number): Vector2D - Divides this vector by a scalar.
  • dot(vector: Vector2D): number - Calculates the dot product of this vector and another vector.
  • cross(vector: Vector2D): number - Calculates the cross product of this vector and another vector.
  • magnitude(): number - Calculates the magnitude (length) of this vector.
  • normalize(): Vector2D - Normalizes this vector (makes it have a magnitude of 1).
  • clone(): Vector2D - Creates a copy of this vector.
  • equals(vector: Vector2D): boolean - Checks if this vector is equal to another vector.
  • toString(): string - Returns a string representation of this vector.
  • distance(vector: Vector2D): number - Calculates the distance to another vector.
  • angle(): number - Calculates the angle of this vector relative to the positive X-axis.
  • rotate(angle: number): Vector2D - Rotates this vector by a given angle.
  • lerp(vector: Vector2D, t: number): Vector2D - Performs linear interpolation between this vector and another vector.
