Question 1

How accurate is the memory usage panel in stats.js?

Accepted Answer

The memory panel (MB) is accurate only in Chrome with the --enable-precise-memory-info flag enabled; it may not work in other browsers or without the flag, and it tracks allocated memory but not detailed garbage collection insights.

Question 2

Can I use stats.js with React or Vue.js applications?

Accepted Answer

Yes, stats.js can be integrated into any JavaScript framework by adding it to component lifecycles or hooks—simply call begin() and end() around monitored code, similar to the basic usage example in the README.

Question 3

How do I add a custom metric panel to stats.js?

Accepted Answer

Use the custom panel support by creating a new Stats instance, calling showPanel() with an index 3 or higher, and updating it in your animation loop with custom data, as implied in the README's code snippet.

Question 4

Is stats.js suitable for production use?

Accepted Answer

Stats.js is designed for development and testing due to its visual overlay and minimal overhead; for production, consider more robust monitoring tools unless you need a lightweight, always-on display in controlled environments.

Question 5

stats.js vs browser DevTools: which is better for performance debugging?

Accepted Answer

Stats.js offers real-time, always-on visual feedback perfect for quick checks during coding, while browser DevTools provide deeper, interactive profiling with more metrics and analysis tools—they serve different purposes, with Stats.js for immediacy and DevTools for thorough investigation.

Question 6

How to remove the stats.js overlay from my page?

Accepted Answer

To remove the overlay, detach the stats.dom element from the DOM, for example by using document.body.removeChild(stats.dom) or hiding it with CSS, as it's a standard HTML element added during setup.
