Memory Leaks on application
Hi everyone. I have memory leaks on my application. I want to test my app but the module (https://nuxt.com/modules/memwatch) seems to be outdated and I can't install it. Do you know any way to test a nuxt app ? I have multiple nuxt app and only one of the causes a memory leak

Hi @K1nggor. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
To test your Nuxt app for memory leaks, the official Nuxt documentation does not mention a dedicated, up-to-date memory leak detection module like memwatch. However, you can use the following approaches based on the available knowledge sources:
1. General Debugging and Profiling
Nuxt supports debugging with Node Inspector and browser DevTools, which can help you monitor memory usage and spot leaks. You can start your Nuxt app in dev mode with debugging enabled: Then, attach Chrome DevTools to profile memory usage and look for leaks. This is a standard approach for Node.js applications and works with Nuxt as well. The documentation provides example configurations for VS Code and JetBrains IDEs to help you debug both client and server sides of your Nuxt app Debugging Guide. 2. Testing Utilities
While Nuxt provides first-class support for unit and end-to-end testing via
Nuxt has built-in features to help prevent memory leaks, such as the
If you suspect a specific Nuxt app is leaking memory, you can use Node.js memory profiling tools (like heap snapshots in Chrome DevTools) while running your app in development or production mode. There is no Nuxt-specific module for this, but standard Node.js techniques apply. 5. Community Advice
According to a related Stack Overflow post, memory leaks in Nuxt apps are often caused by server-side code that cannot be garbage collected, such as uncleaned intervals or misused plugins. Reviewing your code for such patterns and using general Node.js memory profiling is recommended Stack Overflow. Summary:
There is no official or up-to-date Nuxt module for memory leak detection, but you can use Node.js and browser debugging/profiling tools alongside Nuxt's built-in features and testing utilities to identify and address memory leaks in your application. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@nuxt/test-utils, these tools are primarily for functional correctness, not memory profiling. However, you can use them to automate scenarios that might trigger leaks, and then monitor memory usage externally using Node.js or browser tools Testing Guide.
3. Best Practices to Avoid LeaksNuxt has built-in features to help prevent memory leaks, such as the
purgeCachedData experimental option, which ensures that cached data from useAsyncData and nuxtApp.static.data is cleaned up on route navigation. Make sure this is enabled (it is by default) to help avoid common sources of leaks purgeCachedData.

<@192352601591775232> Kapa.ai is still learning and improving, please let me know how I did by reacting below.
I found no solution but testing everything that passed in my mind. I found the solution. it was a firefox extension
Maybe the tips posted here might help?
