abinnovision/nestjs-commons

A collection of common packages for NestJS.

Goals

The packages in this repo share a deliberate house style:

• Class-based DI — no string tokens; injection sites are typed and refactor-safe.
• Schema-driven types — Standard Schema (Zod, ArkType, …) and TypeScript module augmentation, not call-site generics.
• Testable by default — every public token is overrideProvider-friendly; dedicated fakes where it helps.
• Thin wrappers — we glue best-in-class upstream libraries into Nest, not replace them.

Packages

Package	Version	Description
@abinnovision/nestjs-configx		Simple configuration management for NestJS, supporting Standard Schema.
@abinnovision/nestjs-exceptions		Standardized NestJS exception handling with entity-focused exceptions, HTTP awareness, and built-in support for GraphQL and REST APIs.
@abinnovision/nestjs-flydrive		NestJS integration for flydrive with class-token disks, eager fail-fast startup, and a fakes API for tests.
@abinnovision/nestjs-hatchet		NestJS integration for Hatchet workflow orchestration.
@abinnovision/nestjs-healthz		Self-mounting health check module with cross-module attestor discovery and Kubernetes-style probes.
@abinnovision/nestjs-toolkit		NestJS utility library providing Remeda functional helpers, string manipulation, and UUID operations for common development tasks.
