Changelog

• 3/27/2024: Initial Release

Known Bugs

• There is an issue in Safari/WebKit-based browsers where SVG scaling does not work properly alongside transform-origin.
  • Given that it has been broken for so long, a workaround will need to be found (TBD)

Configuration

The only thing you need to configure is the following line:

const TEST_URL = "https://cachefly.cachefly.net/100mb.test";

Change this to a local URL or another test file URL. Valid URLs include:

• /TestFiles/100mb.test
• https://example.com/100mb.test

Do not add a trailing /. The size of each test file is determined by the Content-Length header. In certain cases, this may not be sent.

You will have to modify the following lines in speedtest.js:

const contentLength = response.headers.get('content-length'); <--
const total = parseInt(contentLength, 10);
let loaded = 0;

Set contentLength to your test file's size in bytes.
