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 🙏

Logic Gates as Functions & Expressions

Logic Gates (AND, BUFFER, NAND, NOR, NOT, OR, XNOR, XOR) made available as simple functions and Expressions (Cool feature of this package).

Gates also support both Boolean and number values, here's an example:

import lg from "lgates";

lg.gate.and(true, 1, false);
// Gates will always return a number

It is also possible to import every expression or gate individually:

import {and, singleCase} from "lgates";

// Gate Examples
and(true, 0) // 0

// Expression Examples
singleCase("AB+!B", {a:1, b:0}).res // 1

Install

$ npm install lgates
$ pnpm install lgates
$ yarn add lgates

Usage

import lg from "lgates";

// Gates
const and = lg.gate.and(true, 1);
const buffer = lg.gate.buffer(true);
const nand = lg.gate.nand(true, 1);
const nor = lg.gate.nor(true, 1);
const not = lg.gate.not(true);
const or = lg.gate.or(true, 1);
const xnor = lg.gate.xnor(true, 1);
const xor = lg.gate.xor(true, 1);

Expressions

import lg from "lgates";

// Allowed operators: +, *, !
// Brackets are allowed ()[]{}

const pattern = "AB+!B";
const x = lg.exp.singleCase(pattern, {a: 1});
// Non specified variables are 0 by default
const y = lg.exp.everyCase(pattern);

console.log(x.res); // 1
console.log(x.exp); // (1*0)+1

// calculates every possible case with provided pattern
console.log(y.res); // number[]
console.log(y.exp); // string[]
console.log(y.data); // data[] => {variables + res}[]
