Package Exports

perfrunner-core
perfrunner-core/dist/index.js
perfrunner-core/dist/utils/async
perfrunner-core/dist/utils/async.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (perfrunner-core) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Perfrunner-core

This package was written to simplify performance testing for the web application. It supports:

Network conditions - downloadThroughput, uploadThroughput, latency
CPU throttling
Browser caching and no caching
Multiple runs against the same URL for better precision
Chrome arguments
Storing data between test runs
Tracing in Chrome readable format for better investigation

Installation

npm i perfrunner-core -D

Usage example

import { profile } from 'perfrunner-core';

(async function () {
    const profilingResult = await profile({
        url: 'https://drag13.io',
        network: { downloadThroughput: 1000, uploadThroughput: 500, latency: 200 },
        output: './generated',
        runs: 5,
        throttlingRate: 4,
        timeout: 90000,
    });

    console.log(JSON.stringify(profilingResult));
});

Tracing

After testing, you can find traces in Chrome readable format inside the folder related to the test run. This might be helpful for additional investigation

Tests

npm test
