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 🙏

Servizio di messaggistica applicativa e normalizzazione errori validazione.

Readme

@tc-libs/message

Servizio di messaggistica applicativa e normalizzazione errori validazione.

Il package non contiene ancora un motore i18n attivo: setMessage() al momento ritorna null, ma l'API e gia pronta e viene usata dagli altri package per costruire risposte multilingua o fallback.

Registrazione

MessageModule.register(
  {
    appDefaultLanguage: 'it',
    availableLanguages: ['it', 'en'],
    i18nEnabled: false,
  },
  true,
);

Il modulo applica anche il middleware MessageCustomLanguageMiddleware per leggere la lingua custom dalla request.

Servizio

MessageService espone:

  • getAvailableLanguages()
  • get(key, options?)
  • getRequestErrorsMessage(validationErrors, customLanguages?)
  • getImportErrorsMessage(importErrors, customLanguages?)

Esempio:

const msg = await this.messageService.get('user.created', {
  customLanguages: ['it'],
  properties: { name: 'Mario' },
});

Uso con validation errors

const errors = await this.messageService.getRequestErrorsMessage(
  validationErrors,
  ['it'],
);

Questo e il punto di integrazione usato da @tc-libs/error-handler.

Export pubblici

import {
  IMessage,
  IMessageOptions,
  MessageModule,
  MessageService,
} from '@tc-libs/message';

Nota importante

Lo strato di API e pronto, ma la traduzione vera e propria e da completare. Nei package che lo usano, trattalo come message resolver/pluggable facade piu che come i18n engine finito.

Sviluppo

nx build message
nx test message
