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 🙏

这个库能够处理一组相互关联的变量,并且在修改其中某个的值时同步更改其余的值以满足约束。

详细原理见我的博客

安装方式

$ npm i @nianyi-wang/automatic-constraint-cluster

使用例

下面的例子展示了一个简单的温标转换器。 调整一种温标的数值时,其他温标的数值会随着变化。

import { AutomaticConstraintCluster, RealVariable } from '@nianyi-wang/automatic-constraint-cluster';

const cluster = new AutomaticConstraintCluster();

const kelvin = cluster.AddVariable('kelvin', new RealVariable(0));
const fahrenheit = cluster.AddVariable('fahrenheit', new RealVariable(0));
const celsius = cluster.AddVariable('celsius', new RealVariable(0));

cluster.AddConstraint(fahrenheit, celsius, (f, c) => Math.abs(1.8 * c + 32 - f));
cluster.AddConstraint(kelvin, celsius, (k, c) => Math.abs(k - 273 - c));

if(!cluster.SetValue(fahrenheit, 32))
	console.error('Failed to set variable');
else
	console.log(`${kelvin.value}K = ${celsius.value}C = ${fahrenheit.value}F`);
