Memory-leak-analyzer NPM

Memory Leak Analyzer

Memory Leak Analyzer is a Node.js library for diagnosing and fixing memory leaks in Node.js applications. It provides tools to take heap snapshots, analyze them, and detect potential memory leaks, helping developers ensure their applications run efficiently.

Features

Heap Snapshot Capture: Take snapshots of your application's memory.
Heap Analysis: Analyze heap snapshots to detect potential memory leaks.
Heap Diffing: Compare snapshots over time to find memory growth.
Memory Growth Detection: Automatically detect abnormal memory growth in your application.

Installation

Install the library via npm:

npm install memory-leak-analyzer

Usage

Importing the Library

import MemoryLeakAnalyzer from "memory-leak-analyzer";

const analyzer = new MemoryLeakAnalyzer();

Taking a Heap Snapshot

const snapshotPath = analyzer.takeSnapshot("initial");

Analyzing a Heap Snapshot

analyzer.analyzeSnapshot(snapshotPath);

Comparing Heap Snapshots

analyzer.compareSnapshots(
  "path/to/initial.heapsnapshot",
  "path/to/second.heapsnapshot"
);

Detecting Memory Growth

analyzer.detectGrowth(snapshotPath);

CLI (Command-Line Interface)

The library also provides a command-line interface for quick and easy use.

npx memory-leak-analyzer takeSnapshot --name="initial"
npx memory-leak-analyzer analyzeSnapshot --path="path/to/snapshot"
