Реалізація моніторингу витоків пам’яті в Node.js-додатках з використанням heap-снапшотів

Abstract

Memory leaks in Node.js applications can lead to performance degradation and crashes. Node.js uses automatic garbage collection; however, a memory leak occurs when a block of memory that is no longer needed by the application is not released by the garbage collector. This paper analyzes methods for detecting memory leaks in Node.js applications, with a focus on using heap snapshots for monitoring and diagnostics. The process of obtaining heap snapshots and tools for their analysis using Chrome DevTools are examined. The snapshot data analysis is presented to identify objects that are not freed from memory. Practical recommendations are provided to prevent memory leaks and improve the reliability of Node.js applications.
