Servitect - A one-click Node.js MVC Server generator

Server + Architect = Servitect

Automate the creation of a well-structured Model-View-Controller (MVC) pattern for your Node.js projects with ease. Servitect is designed to help developers quickly scaffold a project, follow best practices, and integrate various functionalities with minimal setup.

🤔 Why Servitect?

Servitect is designed to simplify and accelerate the server development process by automating the setup of essential components for a modern backend. Here's why you should choose Servitect:

• 🏎️ Speedy Development: Perfect for hackathons and rapid prototyping, Servitect allows you to set up a fully functional server in minutes, letting you focus on building unique features and meeting tight deadlines rather than getting stuck in setup.

• 🗄️ MongoDB Integration: With built-in support for MongoDB, Servitect is ideal for modern applications that need a flexible and scalable NoSQL database.

• ⚙️ Customizable: Servitect's menu-driven approach allows you to pick and choose the features you need, giving you flexibility while still automating repetitive tasks.
