curs_memleaks - Linux
Overview
curs_memleaks is a specialized tool designed to detect memory leaks in Node.js applications. It provides detailed information about the source of memory leaks, enabling developers to address these issues efficiently.
Syntax
curs_memleaks [--timeout <seconds>] [--sample-interval <seconds>] [--report-interval <seconds>] [--] <node options> <script>
Options/Flags
- –timeout
: Set the maximum runtime for the memory leak detection process. Default: 600 seconds (10 minutes). - –sample-interval
: Specify the time interval between memory snapshot collections. Default: 2 seconds. - –report-interval
: Set the interval for generating progress reports during memory leak detection. Default: 5 seconds. - —
: Pass additional Node.js options to the script.
Examples
Simple Usage:
curs_memleaks npm start
Custom Configuration:
curs_memleaks --timeout 900 --sample-interval 1 --report-interval 10 npm start
Advanced Script:
curs_memleaks -- node run-script.js
Common Issues
- High CPU Usage: Memory leak detection may consume significant CPU resources. Adjust sample and report intervals to mitigate the impact.
- False Positives: curs_memleaks may identify potential leaks that are not actual memory leaks. Inspect the report carefully and verify the issue.
- Missed Leaks: Ensure the application is running long enough to trigger memory leaks. Consider increasing the timeout option.
Integration
curs_memleaks can be integrated into CI/CD pipelines to automatically detect memory leaks during testing and deployment.
npm run build && npm test && curs_memleaks npm start
