bananest v0.8.0

🐱🍌 BanaNest

BanaNest is a lightweight dependency injection framework inspired by NestJS started as an educational project to understand modern framework architectures, but aims to evolve into a lightweight alternative for applications that need:

• A simplified dependency injection system
• Clean architectural patterns
• Type-safe decorators
• Modular structure without the overhead of larger frameworks

🎯 Purpose

This project is a study implementation that recreates core functionalities found in NestJS, focusing on:

• Understanding how dependency injection works under the hood
• Implementing decorators for routing and DI container
• Creating a modular architecture system
• Building HTTP abstractions similar to NestJS controllers

🏗️ Core Concepts Implemented

Dependency Injection

• Custom DI container implementation
• Constructor injection using decorators
• Singleton and transient lifetime management
• Circular dependency detection

Decorators

• Dependency injection: @Inject(token or class)
• Routing: @Controller(prefix)
• HTTP methods: @Get(path), @Post(path), @Put(path), @Delete(path), @Patch(path)

Modular Architecture

• Module system for organizing code
• Feature modules with their own providers
• Shared modules and services

🚀 Getting Started

# With npm
`npm install bananest`

# With yarn
`yarn add bananest`

🔧 Technical Stack

• TypeScript
• Node.js
• Vitest for testing
• Express.js (as underlying HTTP server)
