## What it is
A reference implementation of Clean Architecture in TypeScript, built as a fictional blogging application (IPoster) using NestJS and TypeORM. It serves as an educational template demonstrating layered architecture, unit testing, and e2e testing practices.

## Use cases
- learn clean architecture in typescript
- example nestjs project structure
- typescript backend boilerplate with typeorm
- how to structure domain layer in nodejs
- reference app for unit and e2e testing in nestjs
- starting point for a clean architecture rest api

## When to choose
- you want a well-structured NestJS + TypeORM example following Clean Architecture principles
- you are learning how to separate domain, application, and infrastructure layers in TypeScript
- you need a tested reference backend to model your own project on

## When to avoid
- you need a production-ready framework or library rather than an educational example
- your stack is not Node.js/TypeScript
- you need a minimal scaffold without opinionated architectural patterns

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: web-framework, orm, testing, e2e-testing, api-framework
- domain: web-development, backend, developer-tools, tutorials
- platform: -
- tags: clean-architecture, nestjs, typeorm, boilerplate, example-app, domain-driven-design, sample-project, nodejs, typescript, docker
