Introduction

Hey guys! Today, we're diving deep into a crucial feature request: a memory usage monitoring utility. This is a game-changer for developers looking to optimize their applications and prevent those dreaded out-of-memory errors. We'll explore the ins and outs of this feature, its functionalities, technical specifications, and why it's so important. So, buckle up and let's get started!

Feature Overview

The main goal here is to implement a memory usage monitoring utility that can track the SDK's memory consumption. This isn't just about knowing how much memory is being used; it's about detecting memory leaks and gaining valuable performance insights. Think of it as a health tracker for your application's memory. A robust memory monitoring tool can help identify bottlenecks, prevent crashes, and ensure smooth operation. It’s like having a vigilant guardian watching over your app’s memory, ready to sound the alarm at the first sign of trouble.

Primary Functionality: Real-time Memory Monitoring with Threshold Alerts

At its core, this utility needs to provide real-time memory monitoring. This means developers can see, at any given moment, how much memory the application is using. But it doesn't stop there. We also need threshold alerts. Imagine setting a limit, say 80% of available memory, and receiving a notification when the application crosses that threshold. This proactive approach allows developers to address potential issues before they become critical problems. Real-time monitoring coupled with threshold alerts is a powerful combination, providing both a snapshot and a warning system for memory usage.

Secondary Functionality: Memory Leak Detection and Cleanup Recommendations

Beyond real-time monitoring, we're also tackling memory leak detection. Memory leaks are insidious; they gradually eat away at available memory, eventually leading to crashes and instability. Our utility should be able to identify these leaks, pointing developers to the areas in the code where memory isn't being properly released. But we're not stopping at detection. The utility should also provide cleanup recommendations. This could include suggestions on how to refactor code, optimize memory usage, or implement better memory management practices. Think of it as a diagnostic tool that not only identifies the problem but also offers solutions.

User Stories: Why This Matters

To truly understand the value of this feature, let's look at a couple of user stories:

  • As a developer, I want memory monitoring so that I can optimize my application's memory usage: This is the bread and butter of performance optimization. Developers need visibility into memory usage to identify areas for improvement. Whether it's reducing memory consumption in a particular function or optimizing data structures, memory monitoring provides the data needed to make informed decisions. It’s about empowering developers to write more efficient code.
  • As a user, I want memory alerts so that I can prevent out-of-memory errors: Out-of-memory errors are a nightmare for users. They lead to crashes, data loss, and a frustrating experience. By implementing memory alerts, we can proactively address potential issues, preventing these errors from ever reaching the user. This is about ensuring a stable and reliable application.

Technical Requirements

Now, let's dive into the technical side of things. Understanding the technical requirements is crucial for a successful implementation.

Architecture Layer: Shared

This memory usage monitoring utility belongs in the Shared architecture layer. This means it's a fundamental component that can be used across different parts of the application. By placing it in the Shared layer, we ensure consistency and avoid duplication of effort. It also promotes a modular design, making the codebase easier to maintain and extend.

Files to Create/Modify: src/shared/utils/memory-monitor.ts

The primary file we'll be working with is src/shared/utils/memory-monitor.ts. This file will house the core logic for our memory monitoring utility. Keeping the code organized and in a dedicated file makes it easier to find, test, and maintain. It’s about following best practices for code organization.

Dependencies: No New Dependencies Needed

One of the great things about this feature is that it doesn't require any new dependencies. This simplifies the implementation and reduces the risk of introducing compatibility issues. We can leverage existing tools and libraries within the project to achieve our goals. It's always a win when we can build a powerful feature without adding extra baggage.

Breaking Changes: No - New Utility Addition

This feature introduces no breaking changes. We're adding a new utility, not modifying existing functionality. This is crucial for ensuring a smooth transition for developers already working with the SDK. It’s about maintaining backward compatibility and minimizing disruption.

Technical Specifications

Let's get into the nitty-gritty details with the technical specifications.

TypeScript: Use Function Types, No Interfaces

We're sticking with TypeScript for this utility, which is excellent for type safety and maintainability. Specifically, we'll be using function types instead of interfaces. Function types provide a concise way to define the shape of functions, making the code cleaner and easier to read. It’s about leveraging the power of TypeScript to write robust and maintainable code.

Testing: Must Include Unit Tests with Memory Monitoring Scenarios

Testing is paramount. We need to ensure our memory monitoring utility is rock solid. This means writing comprehensive unit tests that cover various memory monitoring scenarios. Think about testing cases like: monitoring memory usage under heavy load, detecting memory leaks, and verifying that threshold alerts are triggered correctly. 100% test coverage should be the goal! It’s about building confidence in our code and preventing regressions.

Changelog: Update Both Root and Folder Changelogs

Proper changelog management is essential for communication and collaboration. We need to update both the root changelog and the folder-specific changelog to reflect the addition of this new utility. This ensures that everyone is aware of the changes and can easily track the evolution of the SDK. It’s about keeping the team informed and maintaining a clear history of changes.

Architecture: Follow Clean Architecture with Pure Monitoring Functions

We're adhering to clean architecture principles, which promote separation of concerns and testability. This means our monitoring functions should be pure, meaning they have no side effects and their output depends solely on their input. This makes them easier to test and reason about. It’s about building a maintainable and scalable architecture.

Acceptance Criteria

Finally, let's define the acceptance criteria. These are the conditions that must be met for the feature to be considered complete.

  • [ ] Memory monitoring utility implemented: The core functionality of tracking memory usage must be in place.
  • [ ] Threshold alerts and leak detection: Both threshold alerts and memory leak detection mechanisms must be implemented and working.
  • [ ] Unit tests pass with 100% coverage: All unit tests must pass, ensuring comprehensive test coverage.
  • [ ] Changelogs updated: Both root and folder changelogs must be updated with the relevant information.
  • [ ] Code follows project standards: The code must adhere to the project's coding standards and best practices.
  • [ ] No new warnings or errors: The implementation should introduce no new warnings or errors.

Conclusion

So, there you have it! A comprehensive overview of the memory usage monitoring utility feature request. This is a significant addition that will empower developers to write more efficient applications and prevent memory-related issues. By implementing this utility, we're not just adding a feature; we're investing in the long-term health and stability of our applications. Let's get this done, guys!
