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 🙏

v0.1.1

Published

SDK/Biblioteca para gerenciar parâmetros com diferentes provedores (Google Sheets, DynamoDB, etc.)

Readme

Cellar Parametro Client

SDK/Biblioteca para gerenciar parâmetros com diferentes provedores (Google Sheets, DynamoDB, etc.)

Variáveis de Ambiente

Google Sheets Strategy

# Credenciais do Google Service Account
CELLAR_GOOGLE_CLIENT_EMAIL=your-service-account@project.iam.gserviceaccount.com
CELLAR_GOOGLE_PRIVATE_KEY="-----BEGIN PRIVATE KEY-----\nYOUR_PRIVATE_KEY_HERE\n-----END PRIVATE KEY-----\n"

# Provedor ativo
CELLAR_PARAMETRO_PROVIDER=GOOGLE_SHEET

Como obter as credenciais:

  1. Acesse Google Cloud Console
  2. Crie um Service Account
  3. Gere uma chave JSON
  4. Copie client_email e private_key para as envs
  5. Compartilhe a planilha com o client_email

Importante: A CELLAR_GOOGLE_PRIVATE_KEY deve conter \n literais (como string), não quebras de linha reais.

Uso como SDK/Lib Standalone

Instalação via NPM

npm install @codehiga/cellar-parametros

Uso após instalação

import { CellarParametroClient } from '@codehiga/cellar-parametros';
import { ParametroGoogleSheetsStrategy } from '@codehiga/cellar-parametros/dist/application/parametro/strategies/parametro-google-sheets.strategy';

// Configurar o client com a strategy desejada
const client = new CellarParametroClient({
  strategy: new ParametroGoogleSheetsStrategy()
});

// Usar o client
const parametro = await client.resgatarParametro('CHAVE_CONFIG', {
  planilhaId: 'abc123',
  pagina: 'Config!A:B'
});

console.log(parametro); // { chave: 'CHAVE_CONFIG', valor: '...' }

Uso em Aplicação NestJS

O client já está integrado via DI:

@Injectable()
export class MeuService {
  constructor(
    @Inject(ParametroSymbols.cellarParametroClient)
    private readonly cellarClient: CellarParametroClient
  ) {}

  async executar() {
    const param = await this.cellarClient.resgatarParametro('KEY', opcoes);
  }
}

Criar Strategy Customizada

import type { ParametroStrategy, Parametro } from '@codehiga/cellar-parametros';

interface MinhaOpcoes {
  endpoint: string;
  token: string;
}

export class MinhaCustomStrategy implements ParametroStrategy<MinhaOpcoes> {
  async resgatarParametro(chave: string, opcoes: MinhaOpcoes): Promise<Parametro | null> {
    // Sua lógica aqui
    return Parametro.montar({ chave, valor: '...' });
  }
}

Publicação (para mantenedores)
