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 🙏

Include Models Helper for Sequelize 🚀

npm version License: MIT

Include Models Helper es un paquete que simplifica la creación de consultas de inclusión de modelos relacionados en Sequelize y TypeScript. Permite configurar fácilmente las relaciones entre tus modelos y generar automáticamente las cláusulas include en tus consultas, haciendo que tu código sea más limpio y fácil de mantener.

📦 Instalación

Usa npm o yarn para instalar Include Models Helper en tu proyecto:

npm install sequelize-typescript-include-models

# or
yarn add sequelize-typescript-include-models

📚 Uso

Primero, importa setModels e includeModels desde el paquete sequelize-typescript-include-models:

import { setModels, includeModels } from 'sequelize-typescript-include-models';

Luego, configura tus modelos utilizando la función setModels. Asegúrate de hacer esto solo una vez en tu aplicación:

import { Member } from "../app/backend/models/Member";
import { Company } from "../app/backend/models/Company";
import { Proyect } from "../app/backend/models/Proyect";
// ...

setModels({
  Member,
  Company,
  Proyect,
  // ...
});

Ahora puedes utilizar la función includeModels para generar cláusulas include en tus consultas de Sequelize:

const relations = [
  'Company',
  'ProyectRequest.Team',
  'ProyectRequirements.ProyectRequirementsFiles',
  'ProjectStatus.Status'
];

const proyect: Proyect | null = await Proyect.findByPk(proyectId, {
  include: includeModels(relations),
});

📖 Ejemplo

Digamos que tienes los siguientes modelos en tu aplicación:

User Post Comment Category Supongamos que quieres recuperar un Post junto con su autor (User), los comentarios (Comment) y la categoría (Category) a la que pertenece. Para hacer esto, puedes utilizar includeModels de la siguiente manera:

const relations = [
  'User', // Autor del Post
  'Comment', // Comentarios del Post
  'Category' // Categoría del Post
];

const post = await Post.findByPk(postId, {
  include: includeModels(relations),
});

⚙️ Configuración avanzada

Puedes pasar condiciones adicionales para filtrar modelos relacionados utilizando la sintaxis de dos puntos (:) seguida de una cadena JSON:

const relations = [
  'Comment:{"status": "approved"}'
];

const post = await Post.findByPk(postId, {
  include: includeModels(relations),
});

Esto incluirá solo los comentarios que tengan un estado "aprobado" en el Post.
