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

@koph-npm/browser-storage

Armazenamento seguro e reativo com suporte a localStorage e sessionStorage + sincronização entre abas.

Este pacote fornece uma interface unificada para acesso a armazenamento no navegador com:

  • Prefixo codificado para isolamento de chave
  • Opção de criptografia simples (base64 com prefixo aleatório)
  • Suporte a localStorage e sessionStorage
  • API read/write mais segura e flexível
  • Proxy reativo via createStore() com sincronização automática entre abas

📦 Instalação

npm install @koph-npm/browser-storage

🚀 Uso básico

Classe Storage

import { Storage } from '@koph-npm/browser-storage';

const store = new Storage(true, false, "app");

store.write("user", { name: "Ana" });
console.log(store.read("user")); // { name: "Ana" }

Proxy reativo com createStore()

import { createStore } from '@koph-npm/browser-storage';

const user = createStore("session", { name: "", token: "" });

user.name = "João"; // sincroniza em tempo real com sessionStorage e outras abas
console.log(user.token); // recupera token de forma segura

🧠 API

new Storage(encrypt = false, useSession = false, key = '')

  • encrypt: ativa ofuscação base64 com prefixo aleatório
  • useSession: usa sessionStorage em vez de localStorage
  • key: prefixo para as chaves

Métodos:

  • read(key: string): T | null
  • write(key: string, value: any): void
  • getItem(key: string): string | null
  • setItem(key: string, value: string): void
  • removeItem(key: string): void
  • remove(key: string): void

createStore<T>(name: string, obj: T): T

  • Cria um Proxy reativo sincronizado com sessionStorage

⚠️ Observações

  • A criptografia é apenas uma ofuscação base64 com prefixo aleatório.
  • Eventos storage mantêm valores sincronizados entre abas.
  • Não é recomendada para dados altamente sensíveis.
