Why this repo exists

• NestJS does not provide built-in modules for gRPC, Kafka, authentication systems, API gateways, or search engines
• In production, this usually turns into custom glue code and repeated infrastructure logic copied across services

This repository provides infrastructure-level modules for NestJS that cover these concerns out of the box and remove the need to reimplement the same infra in every project.
