Feature Guides

This section contains detailed guides for implementing specific features in your Navius applications. Each guide provides step-by-step instructions, best practices, and examples for adding functionality to your projects.

Getting Started

For most applications, we recommend implementing features in this order:

1. Database Access - Set up your data layer with PostgreSQL
2. Authentication - Implement secure user authentication
3. Redis Caching - Add basic caching for performance optimization
4. Advanced Caching Strategies - Implement two-tier caching
5. API Integration - Connect with external services
6. Server Customization - Optimize your deployment with feature selection

Available Guides

• Authentication Guide - Implement secure authentication using Microsoft Entra and session management
• Security Best Practices - Essential security measures for Navius applications

Data and Storage

• PostgreSQL Integration - Database integration with PostgreSQL and AWS RDS
• Redis Caching - Implement basic caching with Redis
• Advanced Caching Strategies - Implement two-tier caching with memory and Redis fallback

API and Integration

• API Integration - Connect and integrate with external APIs
• WebSocket Support - Implement real-time communication
• API Design Best Practices - Guidelines for designing robust APIs

Server Customization

• Server Customization CLI - Use the CLI tool to create optimized server builds
• Feature Selection Best Practices - Practical examples for server customization

Implementation Guidelines

When implementing features:

1. Security First: Always follow security best practices outlined in the authentication and security guides
2. Performance: Consider caching strategies and database optimization
3. Testing: Write comprehensive tests for new features
4. Documentation: Update relevant documentation when adding features
5. Optimization: Use the Server Customization System to create lean, optimized builds

Prerequisites for All Features

• Basic understanding of Rust and async programming
• Navius development environment set up
• Access to necessary external services (databases, APIs, etc.)
• Understanding of Architecture Principles
