A minimal JavaScript library for monitoring heap memory usage via performance.memory API.
memory-stats.js is a minimal JavaScript library that monitors and visualizes heap memory usage in web applications using the browser's performance.memory API. It helps developers identify memory leaks and optimize application performance by displaying real-time memory statistics in an on-screen panel.
Frontend developers and web application engineers who need to monitor memory consumption during development and debugging, particularly those working on performance-sensitive applications.
Developers choose memory-stats.js for its simplicity, minimal overhead, and framework-agnostic approach to memory monitoring, providing essential insights without complex setup or dependencies.

The library has no dependencies and minimal overhead, making it ideal for development without impacting app performance, as emphasized in the Key Features.
Displays current, minimum, and maximum memory usage in a compact on-screen panel, providing immediate insights into memory consumption during debugging.
Includes community-contributed adapters for frameworks like React, Angular, and Ember, easing integration into various project types without extra setup.
Can be injected into any webpage via a bookmarklet, allowing for ad-hoc memory monitoring without code changes, as detailed in the README.
Accurate data requires Chrome to be run with --enable-precise-memory-info, limiting usability in standard browsers or environments where flags can't be enabled.
Only monitors JavaScript heap memory via performance.memory API, ignoring other critical aspects like CPU usage, DOM memory, or garbage collection insights.
No built-in support for logging, historical analysis, or automated leak detection, prioritizing simplicity over comprehensive monitoring tools.
