# Introduction

> Welcome to App CR - A RESTful API service for task management with user authentication

## What is App CR?

App CR is a foundational RESTful API service for task management. It provides a backend starting point with user registration and a complete database schema for tasks, designed to be extended with authentication and task management endpoints.

## Tech Stack

App CR is built with modern, reliable technologies:

* **Express.js** - Fast and minimalist web framework for Node.js
* **Prisma ORM** - Next-generation ORM for type-safe database access
* **PostgreSQL** - Robust relational database
* **JWT (JSON Web Tokens)** - Installed for future authentication implementation
* **bcryptjs** - Installed for future password hashing
* **CORS** - Cross-origin resource sharing enabled for frontend integration

## Architecture

The application follows a straightforward architecture:

```
┌─────────────┐
│   Client    │
│ (Frontend)  │
└──────┬──────┘
       │ HTTP Requests
       ↓
┌─────────────┐
│  Express.js │
│   Server    │
└──────┬──────┘
       │ Prisma Client
       ↓
┌─────────────┐
│ PostgreSQL  │
│  Database   │
└─────────────┘
```

## Data Models

App CR uses two primary data models:

### User Model

* `id` - Unique identifier (auto-increment)
* `email` - Unique email address
* `password` - Hashed password
* `tasks` - Relation to user's tasks

### Task Model

* `id` - Unique identifier (auto-increment)
* `title` - Task title
* `description` - Optional task description
* `completed` - Boolean completion status
* `userId` - Foreign key to user
* `author` - Relation to task owner

## Use Cases

App CR is ideal for:

* **Todo Applications** - Build personal or team task management apps
* **Project Management** - Track tasks and assignments across projects
* **Learning Projects** - Understand REST API design and authentication patterns
* **Backend Starter** - Use as a foundation for larger applications
