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 🙏

dcos-auth-client-lib

v1.0.1

Published

Este proyecto implementa la lógica necesaria y con buenas practicas para autenticar correctamente con la librería sls-auth-app

Readme

dcos-auth-client-lib

Cliente OAuth2 (Client Credentials) en TypeScript para autenticación en APIs/entornos serverless.

Instalación

npm install dcos-auth-client-lib

Compatibilidad

  • Node.js >= 18 (usa fetch nativo). Para Node <18, provee un polyfill de fetch (por ejemplo node-fetch).

Uso (recomendado)

La forma recomendada de realizar solicitudes a APIs protegidas por OAuth2 es usar el método request del cliente. Este método se encarga de:

  • Obtener el token (authenticate) cuando no existe.
  • Usar el token en la solicitud (Authorization: Bearer).
  • Refrescar el token si está expirado (si aplica la implementación).

Ejemplo:

import { AuthClient } from 'dcos-auth-client-lib';

const client = new AuthClient({
  baseUrl: 'https://api.ejemplo.com',
  clientId: process.env.CLIENT_ID!,
  clientSecret: process.env.CLIENT_SECRET!,
  scope: process.env.SCOPE || 'admin.rol/admin.rol.read'
});

// request maneja autenticación y refresco de token internamente
const result = await client.request<{ items: any[] }>(
  '/v1/products',
  'GET'
);

console.log(result.items);

Notas:

  • Aunque existen métodos como authenticate(), refreshToken() y getStoredToken(), usar request(...) es la forma más segura y sencilla para llamadas a recursos protegidos, ya que agrupa la lógica de token y la petición en un solo flujo.
  • request acepta los métodos HTTP: 'GET' | 'POST' | 'PUT' | 'DELETE' | 'PATCH' y un body opcional en data.

API principal (resumen)

  • new AuthClient(config: AuthClientConfig)
  • authenticate(): Promise
  • refreshToken(): Promise
  • request(endpoint: string, method: 'GET' | 'POST' | 'PUT' | 'DELETE' | 'PATCH', data?: any): Promise
  • getStoredToken(): AuthToken | null
  • clearToken(): void

(Revisa las definiciones en dist/*.d.ts para la firma exacta.)

Variables de entorno (recomendadas)

  • API_URL — URL base de la API
  • CLIENT_ID — Client ID OAuth2
  • CLIENT_SECRET — Client Secret OAuth2
  • SCOPE — Scopes requeridos

Usa el archivo .env.example como referencia.

Tipos

  • El paquete incluye definiciones TypeScript en dist/ (types en package.json).
