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 🙏

ngx-feda-translate

v0.1.3

Published

Angular 18 translation library with scoped modules, nested JSON and parameter interpolation.

Readme

ngx-feda-translate

Traducciones por scope (módulo) con JSON anidado e interpolación de parámetros. Compatible con Angular 18 y Signals.

Instalación

npm i ngx-feda-translate

Requiere que tus archivos estén en assets/i18n/<scope>/<lang>.json (por defecto lang = es). Puedes cambiar la base y el idioma por defecto sobreescribiendo TRANSLATION_CONSTANTS en tu app si compilas desde fuente.

Uso rápido

  1. Archivos de traducción
assets/
└── i18n/
    ├── global/
    │   └── es.json
    └── home/
        └── es.json

assets/i18n/global/es.json

{ "welcome": "Hola {{user}}", "nested": { "role": "Tu rol es {{role}}" } }
  1. Resolver para precargar
// en tu ruta
{
  path: '',
  resolve: { t: TranslationResolver },
  data: { translationModule: ['global', 'home'] },
  loadComponent: () => import('./home.component').then(m => m.HomeComponent)
}
  1. Pipe y/o directiva de scope
<!-- pipe directo -->
<h1>{{ 'welcome' | t:{ user: 'Eric' }:'global' }}</h1>

<!-- con scope contextual -->
<div appScope="home">
  {{ 'nested.role' | t:{ role: 'Admin' } }}
</div>

API

  • TranslationService.setTranslationsFile(scope: string) carga el JSON del scope.
  • TranslationService.get(key, scope) obtiene la clave.
  • TranslationService.translateWithParams(key, scope, params) obtiene e interpola.
  • TranslationResolver permite precargar scopes desde el router.
  • TranslatePipe (t) para plantillas.
  • TranslationScopeDirective (appScope) para definir/propagar el scope actual.

Estructura y extensiones

  • TRANSLATION_CONSTANTS: BASE_PATH = assets/i18n, DEFAULT_LANGUAGE = es, SCOPE_SEPARATOR = '.'.
  • Puedes guardar en caché (localStorage) envolviendo TranslationLoaderService.
  • Para multi-idioma, expón un servicio que cambie DEFAULT_LANGUAGE o genere rutas por idioma.
