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 🙏

Gatsby Plugin 👀

Install

yarn add use-theme-switcher

or

npm i -S use-theme-switcher

Usage with NextJS

Add the ThemeScriptTag to _document.

This script prevents the white flash of death for static rendered sites. It is very important that the script is added just after the opening body tag and before any other content.

You can also pass the name of your default light and dark themes as props. These defaults will be used when visitor come to your site for the first time and will try to match their preference using window.matchMedia("(prefers-color-scheme: dark)"); and the default light theme if this cannot be determined.

import Document, { Html, Head, Main, NextScript } from 'next/document'
import { ThemeScriptTag } from 'use-theme-switcher';

export default class MyDocument extends Document {
  render() {
    return (
      <Html lang="en">
        <Head>
        </Head>
        <body>
          <ThemeScriptTag defaultDarkTheme="theme-dark" defaultLightTheme="theme-light" />
          <Main />
          <NextScript />
        </body>
      </Html>
    )
  }
}

Add the ThemeProvider to _app.js

import '../styles/index.css'
import { ThemeProvider } from 'use-theme-switcher';

function MyApp({ Component, pageProps }) {
  return <ThemeProvider>
      <Component {...pageProps} />
    </ThemeProvider>
}

export default MyApp

Add your themes

This plugin adds a custom class name to the body element of your site and uses CSS variables to customise your color scheme. Add your themes with the .theme-* format:

.theme-twitter {
  --color-bg-primary: #15202B;
  --color-bg-primary-light: #172D3F;
  --color-bg-accent: #1B91DA; 
  --color-bg-accent-light: #1B91DA; 
  --color-bg-secondary: #657786;
  --color-text-link: #1B91DA;    
  --color-bg-compliment: #112b48;
  --color-bg-default: #192734;
  --color-bg-inverse: #1B91DA;
  --color-text-primary: #fff;
  --color-text-secondary: #f2f2f2;
  --color-text-default: #e9e9e9;
  --color-text-default-soft: #6a6a6a;
  --color-text-inverse: #1B91DA;
  --color-text-inverse-soft: #1B91DA;
}

Switching Themes

To switch themes, use the ThemeContext hook.

import React, { useContext } from "react"
import { ThemeContext } from 'use-theme-switcher';

const { theme, switchTheme } = useContext(ThemeContext);

Add A Theme Switcher Component

You can implement your own theme switcher component but here is a basic example:

import React from "react";

const myThemes = [
    {
        id: "theme-midnightgreen",
        name: "Midnight Green",
    },
    {
        id: "theme-spacegray",
        name: "Space Gray",
    },
    {
        id: "theme-twitter",
        name: "Twitter Dark",
    }
]

const ThemePicker = ({ theme, setTheme }) => {
    if (theme) {
        return (
            <div>
            {myThemes.map((item, index) => {
                const nextTheme = myThemes.length -1 === index ? myThemes[0].id : myThemes[index+1].id;
                
                return item.id === theme ? (
                    <div key={item.id} className={item.id}>
                    <button
                        aria-label={`Theme ${item.name}`}
                        onClick={() => setTheme(nextTheme)}
                    >
                        {item.name}
                    </button>
                    </div>
                ) : null;
                    }
                )}
            </div>
        );
    }
    return null;
};

export default ThemePicker;

ThemeScriptTag Properties

| Prop | Description | :---------------- | :------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | defaultDarkTheme | Initial theme name when prefers-color-scheme: dark
| defaultLightTheme | Initial theme name when preference cannot be determined | | themeStorageKey | Key to persist the theme name in localStorage. Default = "theme". | | minify | Minify the injected script using Terser. Default = true. |

Custom themeStorageKey

If you want to change the themeStorageKey, ensure the same prop value is passed to both the ThemeScriptTag and the ThemeProvider. Example:

function MyApp({ Component, pageProps }) {
  return <ThemeProvider themeStorageKey='my-custom-key'>
      <Component {...pageProps} />
    </ThemeProvider>
}
export default class MyDocument extends Document {
  render() {
    return (
      <Html lang="en">
        <Head>
        </Head>
        <body>
          <ThemeScriptTag 
            defaultDarkTheme="theme-dark" 
            defaultLightTheme="theme-light" 
            themeStorageKey='my-custom-key'
          />
          <Main />
          <NextScript />
        </body>
      </Html>
    )
  }
}
