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 🙏

Guajiritos Drag And Drop

Guajiritos Drag And Drop es una librería para Angular que proporciona un componente para la carga de archivos.

Instalación

yarn add @guajiritos/drag-and-drop

Con pnpm

pnpm add @guajiritos/drag-and-drop

Importar la dependencia en tu proyecto.

import { GuajiritosDragAndDrop } from '@guajiritos/drag-and-drop';

@NgModule({
  imports: [
    GuajiritosGeneralAutocomplete
  ]
})

Importar la etiqueta en el componente correspondiente.

<guajiritos-drag-and-drop></guajiritos-drag-and-drop>

Entrada de datos

Como elementos opcionales se pueden introducir los siguientes campos:

  • accept - Corresponde a los valores que permite la carga de archivos.
  • multiple - Define si permite la carga de archivos multiples.
  • exportBase64Files - Define si devuelve un archivo de tipo File o un arreglo de elementos Base64ExportFile.
<guajiritos-drag-and-drop [multiple]="true"></guajiritos-drag-and-drop>

Interfaz de objetos

interface Base64ExportFile {
  name: string;
  base64: string;
  type: string;
}

Entrada de datos usando formularios reactivos

Este componente permite la entrada de un formulario reactivo para el manejo de los valores.

<guajiritos-drag-and-drop [formControl]="control"></guajiritos-drag-and-drop>

o

<guajiritos-drag-and-drop formControlName="controlName"></guajiritos-drag-and-drop>
import { UntypedFormControl } from '@angular/forms';

export class DragAndDropTest {
  public form: UntypedFormControl = new UntypedFormControl({value: [], disabled: false});

  public reactToChanges(): void {
    this.form.valueChanges
      .subscribe({
        next: (files: File[]): void => {
          // Arreglo de archivos
        }
      });
  }
}

Salida

Si el parámetro exportBase64Files está activo la librería siempre devolverá un arreglo de elementos de tipo Base64ExportFile. De lo contrario devolverá un arreglo de tipo File.

En caso de no usar un formulario reactivo puedes obtener la lista de archivos con la salida del evento files.

<guajiritos-drag-and-drop (files)="getFiles($event)"></guajiritos-drag-and-drop>
export class DragAndDropTest {
  public getFiles(files: File[]): void {
    // Arreglo de archivos
  }
}

Si está activo el parámetro exportBase64Files.

<guajiritos-drag-and-drop (files)="getFiles($event)" [exportBase64Files]="true"></guajiritos-drag-and-drop>
export class DragAndDropTest {
  public getFiles(files: Base64ExportFile[]): void {
    // Arreglo de archivos en base64
  }
}
