Implement Module Lazy Loading

[RUKAYAT-CODER]

Overview

Refactor app.module to use lazy loading for feature modules to improve startup time and reduce memory footprint.

Background

App module imports 20+ modules directly without lazy loading, causing slow startup time and high memory usage even when features aren't used.

Specifications

Modules to Refactor:

• AppModule
• All feature modules

Tasks:

• Convert static imports to dynamic module registration
• Implement on-demand module loading for features
• Add feature flag support for module loading
• Optimize initial bundle size
• Measure startup time improvements
• Document lazy loading strategy

Impacted Files:

• src/app.module.ts (refactor)
• src/auth/auth.module.ts (prepare for dynamic)
• src/payments/payments.module.ts (prepare for dynamic)
• src/ab-testing/ab-testing.module.ts (prepare for dynamic)

Labels: backend, performance, module-architecture, priority-medium

Acceptance Criteria

• Startup time reduced by 30%
• Modules load on-demand
• Feature flags control module loading
• Memory usage reduced for unused features
• All functionality preserved

Hi! I’d love to lead the refactoring of your AppModule to implement a high-performance lazy loading architecture. I have extensive experience optimizing large-scale Node.js backends where boot times and memory overhead are critical constraints. I’ll start by auditing your 20+ static imports to decouple the "Core" dependencies from feature-specific logic, transitioning the application to a dynamic registration pattern that only hydrates modules when they are required.

I will implement a robust feature-flagging system for module loading, ensuring that internal services like Payments or AB-Testing only consume resources when explicitly enabled. My plan includes optimizing the initial bundle size and providing a clear, documented strategy for future feature additions to prevent "import creep." I’ll also perform a comprehensive performance audit—measuring both startup latency and memory footprint—to verify that we meet your 30% reduction goal while maintaining full system stability.

I’m excited to work on refactoring AppModule for lazy loading.
I would implement dynamic module loading and feature-flag-based module control and optimize startup time and reduce memory usage while preserving all functionality.

Looking forward to contributing
Thank you.
