Welcome to ContextJS

ContextJS is a modern, fully object-oriented framework for building scalable TypeScript-based applications. It provides a clean, composable foundation built around:

• Dependency Injection
• Compiler Extensions
• Lifecycle-aware Services
• High-Performance Web Servers
• Tooling with the ctx CLI

Whether you're building a microservice, CLI tool, or a full-stack system, ContextJS gives you the flexibility and performance to scale with confidence.

Why ContextJS?

• Full OOP: Embrace encapsulation, inheritance, and polymorphism—without fighting the runtime.
• Modular Ecosystem: Use only the packages you need.
• Type Safety First: Every public API is fully typed and JSDoc-documented.
• Compiler-Aware: Extend TypeScript with custom AST transformers.
• 100% Tested: Every package ships with full test coverage and clean error handling.
