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

ErrorTranslatePipe

This project was generated using Angular CLI version 20.1.0.

Code scaffolding

Angular CLI includes powerful code scaffolding tools. To generate a new component, run:

ng generate component component-name

For a complete list of available schematics (such as components, directives, or pipes), run:

ng generate --help

Building

To build the library, run:

ng build error-translate-pipe

This command will compile your project, and the build artifacts will be placed in the dist/ directory.

Publishing the Library

Once the project is built, you can publish your library by following these steps:

  1. Navigate to the dist directory:

    cd dist/error-translate-pipe
  2. Run the npm publish command to publish your library to the npm registry:

    npm publish

Running unit tests

To execute unit tests with the Karma test runner, use the following command:

ng test

Running end-to-end tests

For end-to-end (e2e) testing, run:

ng e2e

Angular CLI does not come with an end-to-end testing framework by default. You can choose one that suits your needs.

error-translate-pipe

Documentación de la librería error-translate-pipe (español).

Propósito

Este paquete exporta un pipe standalone CbmErrorTranslatePipe diseñado para traducir ValidationErrors de Angular Forms a mensajes de error legibles por el usuario (en español por defecto). Es útil para mostrar mensajes consistentes en formularios sin repetir lógica en múltiples componentes.

Qué exporta

  • CbmErrorTranslatePipe (pipe standalone)
  • ICbmErrorMessagesMap (interfaz para personalizar mensajes)

Uso rápido

Importa el pipe en el componente (por ser standalone puede usarse directamente en @Component({ imports: [...] })) o incluírlo en un módulo si prefieres.

Ejemplo de uso en template:

<input [formControl]="myControl" />
<div class="text-sm text-red-600">{{ myControl.errors | cbmErrorTranslate }}</div>

Personalizar mensajes

Puedes pasar un map de mensajes personalizados como segundo argumento al pipe:

<div class="text-sm text-red-600">
  {{ myControl.errors | cbmErrorTranslate: { required: 'Se requiere este campo', minlength: 'Demasiado corto' } }}
</div>

API y comportamiento

El pipe acepta:

  • value: ValidationErrors | null | undefined — el objeto errors del AbstractControl.
  • errorMessages?: ICbmErrorMessagesMap — un objeto con claves de error y su texto personalizado.

Reglas de traducción internas (por defecto):

  • required → "Campo requerido"
  • pattern → "Este campo no cumple con el patrón requerido"
  • minlength → "Este campo debe tener al menos X caracteres"
  • maxlength → "Este campo debe tener como máximo X caracteres"
  • min → "Este campo debe tener un valor mínimo de X"
  • max → "Este campo debe tener un valor máximo de X"
  • invalidEmail → "Correo electrónico inválido"
  • invalid → devuelve el valor del error o "Campo inválido"
  • valueSurpassed → utiliza errorMessages del propio objeto de error si está presente

Si no se reconoce la clave de error, el pipe devuelve "Campo inválido".

Testing

El proyecto incluye una spec base (error-translate.pipe.spec.ts). Puedes ejecutar las pruebas con:

ng test

Notas

  • El pipe está diseñado para ser simple y orientado a formularios; si necesitas soporte para i18n completo, considera integrar recursos de traducción (ngx-translate o @angular/localize) y pasar los textos personalizados desde ahí.
