@probe.gl/stats

What is @probe.gl/stats?

@probe.gl/stats is a JavaScript library designed for performance monitoring and statistics collection. It provides tools to track and analyze various metrics, making it useful for performance optimization and debugging in web applications.

What are @probe.gl/stats's main functionalities?

Stat Tracking

This feature allows you to track various statistics, such as frame rates, memory usage, or any custom metrics. The code sample demonstrates how to create a Stats object, increment a frame rate counter, and log the count.

const { Stats } = require('@probe.gl/stats');
const stats = new Stats({id: 'app-stats'});
stats.get('frameRate').incrementCount();
console.log(stats.get('frameRate').count);

Timer

This feature allows you to measure the time taken for specific operations. The code sample shows how to start and end a timer for a 'loadTime' metric and log the last timing.

const { Stats } = require('@probe.gl/stats');
const stats = new Stats({id: 'app-stats'});
stats.get('loadTime').timeStart();
// Perform some operations
stats.get('loadTime').timeEnd();
console.log(stats.get('loadTime').lastTiming);

Aggregated Stats

This feature allows you to aggregate statistics over time. The code sample demonstrates how to add counts to a 'requests' metric and log the total count.

const { Stats } = require('@probe.gl/stats');
const stats = new Stats({id: 'app-stats'});
stats.get('requests').addCount(5);
stats.get('requests').addCount(3);
console.log(stats.get('requests').count);

Other packages similar to @probe.gl/stats

stats.js

stats.js is a lightweight JavaScript library for monitoring performance metrics such as frame rate, memory usage, and custom metrics. It provides a simple interface and visual display for real-time performance tracking. Compared to @probe.gl/stats, stats.js is more focused on real-time visualization and is often used in game development and interactive applications.

perf_hooks

perf_hooks is a Node.js module that provides an API for measuring performance metrics. It includes high-resolution timers and performance observers for tracking various performance-related events. While @probe.gl/stats is more specialized for web applications and custom metrics, perf_hooks offers a broader range of performance measurement tools suitable for Node.js environments.

performance-now

performance-now is a simple library that provides a high-resolution timer for measuring performance in JavaScript. It is often used for benchmarking and performance analysis. Compared to @probe.gl/stats, performance-now is more focused on providing precise timing information rather than a comprehensive statistics tracking system.
