How can I effectively debug a memory leak in a JavaScript application?

Hello everyone,

I’m currently dealing with a challenging issue in my JavaScript application. Over time; I’ve noticed that the application’s memory usage gradually increases; which eventually leads to significant performance degradation and even crashes. I’ve tried various methods to pinpoint the problem but haven’t had much luck so far. :upside_down_face:

Web-based application running on various modern browsers.

Frameworks/Libraries Used: React; Angular, Vue.js

The application performs a range of tasks, including data visualization, user interactions; and dynamic content updates.

Memory usage starts low but increases steadily over time.

As memory usage grows; the application’s responsiveness decreases; and there are noticeable delays and lags.

Eventually; the application may crash or freeze due to excessive memory consumption.

I’ve utilized the built-in memory profiling tools available in Chrome DevTools and Firefox Developer Tools to monitor memory usage and detect potential leaks.

I’ve captured heap snapshots at different points in time to identify unusual memory allocation patterns ; objects that are not being garbage-collected.

I’ve looked for DOM nodes that remain in memory even after they should have been removed.

I’ve inspected event listeners to ensure that they are being properly removed when no longer needed.

I’ve manually reviewed the code for common memory leak patterns, such as global variables; closures that capture large objects; and excessive use of timers.

Despite these efforts, I’m struggling to isolate the root cause of the memory leak. I’m reaching out for a guide that could assist in debugging this issue.

Are there any specialized tools or libraries that can provide more detailed insights or automate the process of finding memory leaks? I have referred

Any advice would be greatly appreciated.

Thank you in advance for your help! :slightly_smiling_face:
