elifrs

Production-ready LLM-friendly Rust web framework CLI - AI agent-optimized development tools

elifrs is the command-line interface for the elif.rs framework - a production-ready, spec-first Rust web framework specifically designed for AI-agent-driven development and LLM-friendly codegen patterns.

🚀 Quick Start

Installation

# Install globally from crates.io
cargo install elifrs

# Verify installation
elif --version

Create Your First App

# 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

Total Test Coverage: 353+ tests passing across all components

🤖 AI-Friendly Development

elif.rs is specifically designed for AI agents and LLM-driven development with predictable patterns:

// 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

// 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

# 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
