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 🙏

Shared error mapping, query guards and service assertions for NestJS

Readme

@seleria/nest-errors

Utilidades compartidas para errores HTTP/RPC, validación de consultas, aserciones de negocio y traducción de errores de PostgreSQL y MySQL.

API

  • AllExceptionsFilter: normaliza excepciones HTTP y RPC y oculta detalles inesperados.
  • assertSafeQuery: bloquea consultas vacías, múltiples sentencias, construcciones peligrosas y SELECT sin WHERE o LIMIT.
  • assertFound, assertNotFound y assertTrue: aserciones de dominio.
  • assertPositiveNumber y assertNotFutureDate: validaciones simples.
  • guardServiceCall: conserva HttpException y convierte errores desconocidos en InternalServerErrorException.
  • mapPostgresError y mapMysqlError: convierten códigos de driver en respuestas HTTP estables.

Mapeo de errores

Los errores de conectividad producen ServiceUnavailableException. Violaciones de unicidad producen ConflictException. Restricciones de integridad o datos producen BadRequestException. Timeouts de consulta producen RequestTimeoutException. Errores de sintaxis o desconocidos se registran y se devuelven como error interno.

Desarrollo

  • bun run build
  • bun run lint
  • bun run format:check

Las cadenas de error de sistema están en inglés técnico para logs y APIs internas. La capa de frontend debe traducirlas antes de mostrarlas al usuario.
