Web Page Load Performance Tester\n\nCLI to test performance page load trials on Chromium, Firefox, and WebKit.\n\nUses the beautiful [playwright](https://github.com/microsoft/playwright) package underneath.\n\n_Note: This package is still in pre-release and subject to possible change._\n\n## Install\n\nInstall globally using NPM.\n\n```sh\nnpm install -g @kyle-west/perf-test\n```\n\n## Usage\n\nThe `perf` CLI simply needs a URL to test against, and a count for the number of trials to run (defaults to 3).\n\n```sh\nperf \u003curl\u003e [\u003cnumber of trials\u003e]\n```\n\n### Example\n\nRunning: `perf https://github.com/kyle-west 3` will test 3 page load trials of loading github.com. It will output something of the following:\n\n```\nTime Trials for https://github.com/kyle-west on Thu Jul 09 2020\n\n\nTime Trials for Chromium Browser\n┌─────────┬─────────────┬────────────────┬──────────────────────────┬──────────────┐\n│ (index) │ responseEnd │ domInteractive │ domContentLoadedEventEnd │ loadEventEnd │\n├─────────┼─────────────┼────────────────┼──────────────────────────┼──────────────┤\n│    0    │    2269     │      2420      │           2420           │     2772     │\n│    1    │     388     │      553       │           554            │     891      │\n│    2    │     372     │      675       │           675            │     841      │\n└─────────┴─────────────┴────────────────┴──────────────────────────┴──────────────┘\nChromium Averages\n┌──────────────────────────┬────────────────────┐\n│         (index)          │       Values       │\n├──────────────────────────┼────────────────────┤\n│       responseEnd        │ 1009.6666666666666 │\n│      domInteractive      │        1216        │\n│ domContentLoadedEventEnd │ 1216.3333333333333 │\n│       loadEventEnd       │ 1501.3333333333333 │\n└──────────────────────────┴────────────────────┘\n\n\nTime Trials for Firefox Browser\n┌─────────┬─────────────┬────────────────┬──────────────────────────┬──────────────┐\n│ (index) │ responseEnd │ domInteractive │ domContentLoadedEventEnd │ loadEventEnd │\n├─────────┼─────────────┼────────────────┼──────────────────────────┼──────────────┤\n│    0    │     532     │      906       │           910            │     1096     │\n│    1    │     542     │      916       │           920            │     1105     │\n│    2    │     546     │      920       │           947            │     1129     │\n└─────────┴─────────────┴────────────────┴──────────────────────────┴──────────────┘\nFirefox Averages\n┌──────────────────────────┬───────────────────┐\n│         (index)          │      Values       │\n├──────────────────────────┼───────────────────┤\n│       responseEnd        │        540        │\n│      domInteractive      │        914        │\n│ domContentLoadedEventEnd │ 925.6666666666666 │\n│       loadEventEnd       │       1110        │\n└──────────────────────────┴───────────────────┘\n\n\nTime Trials for WebKit Browser\n┌─────────┬─────────────┬────────────────┬──────────────────────────┬──────────────┐\n│ (index) │ responseEnd │ domInteractive │ domContentLoadedEventEnd │ loadEventEnd │\n├─────────┼─────────────┼────────────────┼──────────────────────────┼──────────────┤\n│    0    │     305     │      502       │           502            │     828      │\n│    1    │     315     │      529       │           529            │     846      │\n│    2    │     304     │      497       │           498            │     819      │\n└─────────┴─────────────┴────────────────┴──────────────────────────┴──────────────┘\nWebKit Averages\n┌──────────────────────────┬───────────────────┐\n│         (index)          │      Values       │\n├──────────────────────────┼───────────────────┤\n│       responseEnd        │        308        │\n│      domInteractive      │ 509.3333333333333 │\n│ domContentLoadedEventEnd │ 509.6666666666667 │\n│       loadEventEnd       │        831        │\n└──────────────────────────┴───────────────────┘\n```\n\n### Run a script\n\n```sh\nperf --script \u003cfilename\u003e [--engine \u003cchromium|firefox|webkit\u003e]\n```\n\nScripts must be modules of the form:\n\n```js\nmodule.exports = async () =\u003e {\n  // page, browser, engine, engineName, context available globally\n  await page.goto(\"https://google.com\")\n}\n```\n\n### Record Video\n\nInclude the `--record-video` in the arguments list to save a local file. _Note this feature only works in script mode for Chromium browsers_\n\n```sh\nperf --script \u003cfilename\u003e --record-video \u003cvideo-name\u003e\n```\n\nFile will be saved to `\u003cvideo-name\u003e.mp4`\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fkyle-west%2Fperf-test","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fkyle-west%2Fperf-test","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fkyle-west%2Fperf-test/lists"}
