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.

Tiled Geometry

Utilities for 2-D tiled geometry

This library contains several useful functions and classes for dealing with 2-D tiled geometry.

Installation

npm install tiled-geometry

API

Constants and utlities for 2-D tiled coordinate spaces:

Direction - constants for eight compass directions
Turn - constants for rotation among eight compass directions
CardinalDirection - constants for four cardinal directions
CardinalTurn - constants for rotation among four cardinal directions
CardinalDirectionFlags - bitmask constants for four cardinal directions
Flip - constants for mirroring the coordinate space
CardinalOrientation - constants combining CardinalDirection and Flip
Axis - constants for the two major axes

Classes for coordinates, shapes, masks, and more:

Offset - a location or relative offset
Size - a two-dimensional extent
Rectangle - a rectangle (with offset and size)
Mask - a rectangular area with boolean values for each cell
MaskRectangle - a mask with an offset
RasterMask - a mask encoded as "raster lines"
CardinalPath - a path on the grid, moving only in the four cardinal directions
TransformRectangle - maps a rectangular area onto a grid with transformations
