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 🙏

@barso/ui

v0.6.3

Published

Barso UI

Readme

@barso/ui

A React component library.

Installation

To install the package, use:

npm i @barso/ui

Configure Next.js

In your next.config.js, add @primer/react and @barso/ui to transpilePackages:

// next.config.js
module.exports = {
  transpilePackages: ['@primer/react', '@barso/ui'],
};

Theme Setup

To configure theming, first import the global CSS file in your main application file:

// app/layout.js (App Router) or pages/_app.js (Pages Router)
import '@barso/ui/css';

The library provides two properties for theme control:

  • colorMode: Sets a fixed theme, such as "dark" or "light", preventing automatic switching.
  • defaultColorMode: Enables automatic switching based on the user’s preference (light/dark mode).

The usage of these properties depends on which Next.js router you are using:

App Router

In the App Router, wrap your app with PrimerRoot. This component creates the base structure for the <html>, so it also accepts the lang attribute. You can use either defaultColorMode (for automatic switching) or colorMode (for a fixed theme):

// app/layout.js
import { PrimerRoot } from '@barso/ui';
import '@barso/ui/css';

export default function Layout({ children }) {
  return (
    <PrimerRoot
      lang="en"
      defaultColorMode="dark" // Enables theme switching
      // colorMode="dark" // Uses a fixed theme
    >
      {children}
    </PrimerRoot>
  );
}

Pages Router

In Pages Router, you must add _document.js to ensure proper theme setup:

// pages/_document.js
export { Document as default } from '@barso/ui/document';

In _app.js, you can use either AutoThemeProvider or ThemeProvider:

  1. If you want to use theme switching, wrap your app with AutoThemeProvider and pass the defaultColorMode property:
// pages/_app.js
import { AutoThemeProvider } from '@barso/ui';
import '@barso/ui/css';

export default function NextApp({ Component, pageProps }) {
  return (
    <AutoThemeProvider defaultColorMode="dark">
      <Component {...pageProps} />
    </AutoThemeProvider>
  );
}
  1. If you want to use a fixed theme, wrap your app with ThemeProvider and pass the colorMode property:
// pages/_app.js
import { ThemeProvider } from '@barso/ui';
import '@barso/ui/css';

export default function NextApp({ Component, pageProps }) {
  return (
    <ThemeProvider colorMode="dark">
      <Component {...pageProps} />
    </ThemeProvider>
  );
}

Note: Although AutoThemeProvider supports setting a fixed theme using colorMode, it is recommended to use ThemeProvider instead when a fixed theme is required. This ensures that the theme is applied immediately.

Configure Vitest

In vitest.config.js, set test.server.deps.inline to true:

// vitest.config.js
test.server.deps.inline: true
