Code Generator

Generate production-ready boilerplate code instantly.

What This Does

• Project Scaffolds — Python, Node.js, Go, Rust project structure
• CRUD Operations — Create, Read, Update, Delete boilerplate
• API Clients — REST and GraphQL client generators
• Database Models — SQLAlchemy, Prisma, TypeORM models
• Test Templates — Unit tests, integration tests, mocks
• Config Files — Docker, CI/CD, linting, formatting

Quick Start

# Generate a new Python project
neckr0ik-code-generator scaffold python my-project

# Generate CRUD operations for a model
neckr0ik-code-generator crud User --fields "name,email,created_at"

# Generate an API client
neckr0ik-code-generator api-client --spec https://api.example.com/openapi.json

# Generate tests
neckr0ik-code-generator tests --source ./src --type unit

Example: Python CRUD

# Generated: user_crud.py

from typing import List, Optional
from sqlalchemy.orm import Session
from models import User
from schemas import UserCreate, UserUpdate

class UserCRUD:
    """CRUD operations for User model."""

    def create(self, db: Session, user: UserCreate) -> User:
        """Create a new user."""
        db_user = User(
            name=user.name,
            email=user.email,
        )
        db.add(db_user)
        db.commit()
        db.refresh(db_user)
        return db_user

    def get(self, db: Session, user_id: int) -> Optional[User]:
        """Get a user by ID."""
        return db.query(User).filter(User.id == user_id).first()

    def get_multi(self, db: Session, skip: int = 0, limit: int = 100) -> List[User]:
        """Get multiple users."""
        return db.query(User).offset(skip).limit(limit).all()

    def update(self, db: Session, user_id: int, user: UserUpdate) -> Optional[User]:
        """Update a user."""
        db_user = self.get(db, user_id)
        if db_user:
            for key, value in user.dict(exclude_unset=True).items():
                setattr(db_user, key, value)
            db.commit()
            db.refresh(db_user)
        return db_user

    def delete(self, db: Session, user_id: int) -> bool:
        """Delete a user."""
        db_user = self.get(db, user_id)
        if db_user:
            db.delete(db_user)
            db.commit()
            return True
        return False
