# Sharenet
A Rust backend for performing CRUD operations on various struct types (e.g., products, users) that uses a clean architecture with configurable storage and interface layers.
## Features
- Clean architecture with separate domain, application, and infrastructure layers
- Multiple interface options:
- HTTP REST API
- Command Line Interface (CLI)
- Text User Interface (TUI)
- Configurable storage backends:
- In-memory storage
- PostgreSQL database
- Generic implementations for easy extension
- Static dispatch with generic traits
- Axum-based HTTP API
- Clap-based CLI
- Ratatui-based TUI

## Building
```bash
cargo build
```
## Running
### HTTP API with in-memory storage
```bash
cargo run --bin sharenet-api-memory
```
### HTTP API with PostgreSQL
```bash
cargo run --bin sharenet-api-postgres
```
### CLI with in-memory storage
```bash
cargo run --bin sharenet-cli-memory user create --username john --email john@example.com
cargo run --bin sharenet-cli-memory user list
cargo run --bin sharenet-cli-memory product create --name "Product 1" --description "Description"
cargo run --bin sharenet-cli-memory product list
```
### CLI with PostgreSQL
```bash
cargo run --bin sharenet-cli-postgres user create --username john --email john@example.com
```
### TUI with in-memory storage
```bash
cargo run --bin sharenet-tui-memory
```
### TUI with PostgreSQL
```bash
cargo run --bin sharenet-tui-postgres
```
## Database Setup
### Using SQLx CLI
1. Install SQLx CLI:
```bash
cargo install sqlx-cli
```
2. Create the database:
```bash
sqlx database create
```
3. Run migrations:
```bash
sqlx migrate run
```
