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 🙏

hash-states

High-performance collection of states for easy generation of hash strings.

Usage:

import { HashStates } from 'hash-states';

const states = new HashStates();

states
  .clear()
  .setString("name", "Shawn")
  .setNumber("age", 30)
  .setBoolean("human", true)
  .setBoolean("male", true)
  .setBoolean("awesome", true)
  .setBoolean("sad", false);

console.log(states.getHash()); // Shawn|30|7
console.log(states.getString("name")); // Shawn
console.log(states.getBoolean("awesome")); // true

For space efficiency, all boolean values are stored in binary form. Therefore, the aforementioned example would be stored as 111, which is equivalent to 7 in decimal notation. So if numerous Boolean values are set, HashStates will significantly shorten the length of the resulting hash string.

Benchmark

here is the benchmark result of HashStates compared to Object:

set values:
states x 57,623 ops/sec ±3.01% (74 runs sampled)
_array x 13,929 ops/sec ±0.24% (95 runs sampled)
object x 72,747 ops/sec ±0.41% (93 runs sampled)
Fastest is object
get hash:        
states x 147,151 ops/sec ±0.23% (97 runs sampled)
_array x 184,957 ops/sec ±0.18% (95 runs sampled)
object x 45,221 ops/sec ±0.16% (96 runs sampled)
Fastest is _array
hash1Count 1114  
hash2Count 1629  
get values:      
states x 1,101,099 ops/sec ±0.68% (90 runs sampled)
_array x 63,943 ops/sec ±0.42% (93 runs sampled)
object x 359,494 ops/sec ±0.19% (95 runs sampled)
Fastest is states
all:
states x 42,122 ops/sec ±0.96% (88 runs sampled)
_array x 24,750 ops/sec ±0.19% (95 runs sampled)
object x 23,366 ops/sec ±0.30% (95 runs sampled)
Fastest is states

While HashStates is marginally slower in setting values, it exhibits significant performance advantages in getHash and getValue operations. Overall, its performance is nearly twice as efficient as a standard Object.
