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

@mafesoftware/permisos

Presets de rol y modulos por plan, con excepciones. Puro.

Parte de la familia de paquetes de MAFE Software: sin dependencias de framework, sin ORM, y puros salvo donde se indique. Todo lo que sale a la red acepta un fetch inyectable, así que los tests corren sin red.

bun add @mafesoftware/permisos

La documentación de cada función está en src/index.ts, con el motivo de cada decisión al lado. Los tests (tests/) son la otra mitad de la documentación: cada uno dice qué bug evita.

API

crearSistema({ claves, presets })

Declara un sistema de presets con excepciones (sirve igual para roles de usuario que para módulos contratados por plan).

import { crearSistema } from "@mafesoftware/permisos";

export const ROLES = crearSistema({
  claves: ["socios.ver", "socios.editar", "cobranzas.cobrar"] as const,
  presets: {
    duenio: "todas",
    tesoreria: ["socios.ver", "cobranzas.cobrar"],
    porteria: ["socios.ver"],
  },
});

ROLES.tiene("porteria", { "socios.editar": true }, "socios.editar"); // true (excepción concede)
ROLES.tiene("duenio", { "cobranzas.cobrar": false }, "cobranzas.cobrar"); // false (excepción quita)
ROLES.efectivas("tesoreria", null); // Set { "socios.ver", "cobranzas.cobrar" }
ROLES.delPreset("porteria"); // Set { "socios.ver" }
ROLES.minimas("tesoreria", ["socios.ver"]); // { "cobranzas.cobrar": false }
ROLES.limpiar("porteria", { "socios.ver": true }); // {} (no dice nada distinto del preset)
ROLES.esClave("socios.ver"); // true

leerExcepciones(crudo, esClave)

Lee un mapa de excepciones que vino de la base (jsonb) o de un formulario, descartando cualquier valor que no sea booleano (un "false" de texto es true en JavaScript, y coercionarlo concedería el permiso).

import { leerExcepciones } from "@mafesoftware/permisos";

leerExcepciones({ "socios.ver": true, "socios.editar": "false" }, ROLES.esClave);
// { "socios.ver": true }  (la clave con basura se descarta, no se coerciona)
