🚀 HealOps: Self-Healing Assistant for Microservices
Welcome to HealOps — a powerful VSCode extension that empowers developers to build fault-tolerant microservices with ease and confidence.
Built with 💙 for developers who value resilience, automation, and clean code.
🧠 What is HealOps?
HealOps is an intelligent VSCode extension that performs real-time static code analysis on JavaScript/TypeScript microservices and:

- 🛠️ Suggests and applies AST-based fixes directly in your code
- 👀 Lets you preview, apply, or ignore fixes in an interactive sidebar
- 📊 Generates reports for compliance and tracking
