probe.gl

What is probe.gl?

probe.gl is a JavaScript library designed for logging, benchmarking, and testing in web applications. It provides a suite of tools to help developers measure performance, debug issues, and ensure code quality.

What are probe.gl's main functionalities?

Logging

probe.gl provides a flexible logging system that allows developers to log messages at different levels (log, warn, error). The log messages can be filtered based on their severity.

const {Log} = require('probe.gl');
const log = new Log({id: 'my-app'});
log.log(1, 'This is a log message')();
log.warn('This is a warning message')();
log.error('This is an error message')();

Benchmarking

probe.gl includes a benchmarking tool that helps developers measure the performance of their code. It allows for the addition of multiple tests and provides detailed results after running the benchmarks.

const {Bench} = require('probe.gl');
const bench = new Bench({id: 'my-benchmark'});
bench.add('test1', () => {
  // Code to benchmark
});
bench.run().then(results => {
  console.log(results);
});

Testing

probe.gl offers a simple testing framework that can be used to write and run tests. It supports assertions and provides a straightforward way to ensure code correctness.

const {Test} = require('probe.gl');
const test = new Test({id: 'my-test'});
test('example test', t => {
  t.ok(true, 'This test should pass');
  t.end();
});
test.run();

Other packages similar to probe.gl

winston

Winston is a versatile logging library for Node.js. It provides a flexible and extensible logging system with support for multiple transports (e.g., console, file, HTTP). Compared to probe.gl, Winston focuses solely on logging and does not include benchmarking or testing features.

benchmark

Benchmark.js is a popular library for benchmarking JavaScript code. It provides high-resolution timers and statistically significant results. Unlike probe.gl, Benchmark.js is dedicated to benchmarking and does not offer logging or testing capabilities.

mocha

Mocha is a feature-rich JavaScript test framework running on Node.js and in the browser. It makes asynchronous testing simple and fun. Mocha focuses on testing and does not include logging or benchmarking features, making it a more specialized tool compared to probe.gl.
