A comprehensive collection of Angular best practices, architectural patterns, and real-world examples for building scalable, maintainable, and high-performance applications.
This repository is designed for:
- 👨💻 Angular Developers
- 🏗️ Senior Engineers & Architects
- 🎯 Interview Preparation
- 📚 Learning Production-Ready Angular
- 💼 Recruiters evaluating Angular expertise
Rather than explaining only how to write Angular code, this repository focuses on why certain approaches are preferred, their trade-offs, and when they should (or should not) be used.
Angular is a powerful framework, but many codebases become difficult to maintain due to poor architectural decisions rather than incorrect syntax.
This repository aims to bridge that gap by covering:
- Modern Angular development
- Scalable architecture
- Performance optimization
- Maintainability
- Best coding practices
- Real-world scenarios
- Common interview questions
Every topic includes practical examples with explanations and architectural reasoning.
