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 🙏

Tailwindcss Overrides

A function to remove clashing Tailwindcss classes, where the right-most one wins.

Examples:

import { overrideTailwindClasses } from 'tailwind-override'

overrideTailwindClasses('pt-2 pt-4')
// => 'pt-4'

overrideTailwindClasses('text-pink-200 text-blue-200')
// => 'text-blue-200'

overrideTailwindClasses('text-pink-200 pt-2')
// => 'text-pink-200 pt-2' (don't clash)

overrideTailwindClasses('orange apple')
// => 'orange apple' (not tailwind classes)

overrideTailwindClasses('dark:md:text-pink-200 dark:md:text-blue-200')
// => 'md:text-pink-200 md:text-blue-200'

overrideTailwindClasses('text-pink-500 !text-[#ffaa11]/25')
// => '!text-[#ffaa11]/25'

This helps define React Components where tailwind classes are overrideable.

✅ No external dependencies

✅ Works with all tailwind classes

✅ Supports prefixes & variants e.g. md:*

✅ Supports tailwind's jit syntax e.g: text-[#ffaa11]

✅ Small bundle size (~31KB out the box)

Usage

yarn add tailwind-override
import { overrideTailwindClasses } from 'tailwind-override'
overrideTailwindClasses('pt-2 pt-4')
// => 'pt-4'

React example

Problem:

const Text = (props) => {
  return <p className={`text-pink-200 ${props.className}`}>{props.children}</p>
}

<Text className="text-blue-200">Hello</Text> // Not obvious if this will render pink or blue???

Solution:

const Text = (props) => {
  return <p className={overrideTailwindClasses(`text-pink-200 ${props.className}`)}>{props.children}</p>
}

<Text className="text-blue-200">Hello</Text> // this is blue!

With classnames

import classNamesOriginal from 'classnames'
import { overrideTailwindClasses } from 'tailwind-override'

export const classNames = (...args) => overrideTailwindClasses(classNamesOriginal(...args))

Options

Prefix

Defaults to ''

Supports Tailwind's prefix functionality.

overrideTailwindClasses('prefix-pt-2 prefix-pt-4', { prefix: 'prefix-' })
// => 'prefix-pt-4'

Jit

Defaults to true

Supportss Tailwind's jit syntax.

overrideTailwindClasses('!text-[#aabbcc]/5 !text-[#ffaa11]/25', { jit: true })
// => '!text-[#ffaa11]/25'
overrideTailwindClasses('!text-[#aabbcc]/5 !text-[#ffaa11]/25', { jit: false })
// => '!text-[#aabbcc]/5 !text-[#ffaa11]/25'

Cache rule look ups

Defaults to: true

If set to true the library caches lookups for the same class e.g. text-pink-200, so next time it will not need to look up the rule again.

overrideTailwindClasses('text-pink-200 text-pink-300', { ruleLookupCache: true })
// => 'text-pink-200' and 'text-pink-300' rules now cached, won't be looked up again
