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 🙏

Readme

@seedgrid/fe-theme

Sistema de temas do SeedGrid que gera paletas harmônicas, suporta os modos light/dark/auto, expõe tokens prontos e permite troca de tema em tempo de execução.

Características

  • Geração automática de paletas a partir de uma cor seed com rampas completas (50‑900).
  • Modo auto que respeita a preferência do sistema, além de light e dark.
  • Persistência de preferências (seed, mode, radius) no localStorage.
  • Tokens CSS (--sg-*) que se integram facilmente com Tailwind, CSS-in-JS ou classes utilitárias.
  • Hooks reativos (useSgTheme) e SeedThemeProvider para trocar tema, atualizar modos e personalizar variáveis.
  • Híbrido com ThemeProvider antigo para migração suave.

Instalação

pnpm add @seedgrid/fe-theme

Uso básico

import { SeedThemeProvider } from "@seedgrid/fe-theme";

export default function Root({ children }: { children: React.ReactNode }) {
  return (
    <SeedThemeProvider
      initialTheme={{
        seed: "#16803D",
        mode: "auto",
        radius: 12,
        persistMode: true
      }}
    >
      {children}
    </SeedThemeProvider>
  );
}

Hooks e APIs

  • useSgTheme() retorna { currentMode, setMode, seed, setTheme, reset }.
  • SeedThemeProvider aceita initialTheme, persistMode, seed, radius e customVars.
  • ThemeProvider/useTheme antigos permanecem como alias para facilitar migração.

Exemplos

Toggle de modo

import { useSgTheme } from "@seedgrid/fe-theme";

export function ThemeToggle() {
  const { currentMode, setMode } = useSgTheme();

  return (
    <button
      onClick={() => setMode(currentMode === "light" ? "dark" : "light")}
    >
      Alternar para {currentMode === "light" ? "dark" : "light"}
    </button>
  );
}

Atualizar seed e tokens adicionais

const { setTheme } = useSgTheme();

setTheme({
  seed: "#0EA5E9",
  customVars: {
    "--sg-radius": "6px",
    "--sg-border": "214 41 132"
  }
});

Variáveis CSS disponíveis

  • --sg-bg, --sg-surface, --sg-text, --sg-muted, --sg-border, --sg-ring
  • Paletas completas --sg-{primary,secondary,tertiary,success,warning,error,info}-{50..900}
  • Tokens de componentes como --sg-btn-{variant}-bg, --sg-input-border, --sg-card-bg, --sg-radius

Integração com Tailwind

Use rgb(var(--sg-primary-600)) em classes utilitárias para aplicar cores reativas:

<button className="bg-[rgb(var(--sg-primary-600))] text-[rgb(var(--sg-on-primary))]">
  Salvar
</button>

Migração do provider antigo

// 🔴 Antigo (deprecated)
import { ThemeProvider, useTheme } from "@seedgrid/fe-theme";

// ✅ Novo recomendado
import { SeedThemeProvider, useSgTheme } from "@seedgrid/fe-theme";
