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

@tc-libs/error-interface

Definisce i contratti TypeScript condivisi per rappresentare errori applicativi e errori di importazione.

Questo package non contiene eccezioni NestJS, filtri o logica runtime: espone solo tipi e costanti riusabili.

Export pubblici

import {
  ERROR_TYPE,
  IErrors,
  IErrorsImport,
  IValidationErrorImport,
} from '@tc-libs/error-interface';

Tipi disponibili

IErrors

Rappresenta un singolo errore applicativo normalizzato:

type IErrors = {
  message: string;
  property: string;
};

Uso tipico:

const errors: IErrors[] = [
  { property: 'email', message: 'email must be valid' },
];

IErrorsImport

Rappresenta un errore associato a una riga di import:

type IErrorsImport = {
  row: number;
  file?: string;
  errors: IErrors[];
};

Utile per import massivi da CSV/XLSX dove devi restituire al chiamante il dettaglio per record.

IValidationErrorImport

Variante pensata per interoperare con class-validator:

type IValidationErrorImport = {
  row: number;
  file?: string;
  errors: ValidationError[];
};

Enum disponibili

ERROR_TYPE

Classifica il tipo di errore:

ERROR_TYPE.DEFAULT;
ERROR_TYPE.IMPORT;

Tipicamente viene usato nei package superiori per differenziare la serializzazione o il trattamento dell'errore.

Quando usarlo

Usa questo package quando vuoi:

  • condividere interfacce errore tra librerie
  • tipizzare errori di validazione/import senza introdurre dipendenze runtime aggiuntive
  • evitare duplicazioni di DTO o interfacce negli handler applicativi

Sviluppo

nx build error-interface
nx test error-interface
