**elifrs** is the command-line interface for the [elif.rs framework](https://github.com/krcpa/elif.rs) - a production-ready, spec-first Rust web framework specifically designed for AI-agent-driven development and LLM-friendly codegen patterns.
## 🚀 Quick Start
### Installation
```bash
# Install globally from crates.io
cargo install elifrs
# Verify installation
elif --version
```
### Create Your First App
```bash
# Create a new elif.rs application
elif new my-todo-app --path ./projects/
cd projects/my-todo-app
# Set up database (PostgreSQL required)
export DATABASE_URL="postgresql://user:pass@localhost:5432/myapp_dev"
# Create your first model with migration
elif model add User email:string,name:string,age:int
# Create and run migrations
elif migrate create create_users_table
elif migrate run
# Check migration status
elif migrate status
# Generate project overview
elif map --json > project_map.json
# Run tests and validation
elif test
elif check
# Start development
cargo run
```

## 🤖 AI-Friendly Development
elif.rs is specifically designed for AI agents and LLM-driven development with predictable patterns:
```rust
// Generated application structure uses clean, AI-parseable patterns
use elif_core::{Application, Module, ServiceProvider, Container};
use elif_orm::{DatabaseServiceProvider, Model};
use elif_http::Server;
// Clean dependency injection
let mut app = Application::builder()
.provider(DatabaseServiceProvider::new(database_url))
.module(ApiModule::new())
.build()?;
// Production-ready server with middleware
let server = Server::new(container)
.middleware(SecurityMiddleware::strict())
.middleware(LoggingMiddleware::structured())
.router(api_router);
server.listen("0.0.0.0:3000").await?;
```
### **Model Definition Example**
```rust
// AI-generated models with elif CLI
# elif model add User email:string,name:string,active:bool
// Results in clean, typed model:
use elif_orm::Model;
use serde::{Serialize, Deserialize};
use uuid::Uuid;
#[derive(Debug, Serialize, Deserialize, Model)]
pub struct User {
pub id: Uuid,
pub email: String,
pub name: String,
pub active: bool,
pub created_at: DateTime<Utc>,
pub updated_at: DateTime<Utc>,
}
// Automatic CRUD operations
let user = User::find(&pool, user_id).await?;
let users = User::all(&pool).await?;
let count = User::count(&pool).await?;
```
### **Database Migrations**
```bash
# Create migration
elif migrate create add_users_table
# Auto-generated SQL with proper structure
# migrations/20241215120000_add_users_table.sql
CREATE TABLE users (
id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
email TEXT NOT NULL UNIQUE,
name TEXT NOT NULL,
active BOOLEAN NOT NULL DEFAULT true,
created_at TIMESTAMPTZ NOT NULL DEFAULT NOW(),
updated_at TIMESTAMPTZ NOT NULL DEFAULT NOW()
);
# Run migrations
elif migrate run
# ✓ Applied 1 migration(s) successfully: add_users_table
```
