Package Exports

sitespeed.io
sitespeed.io/lib/sitespeed
sitespeed.io/lib/support/messageMaker
sitespeed.io/lib/support/statsHelpers

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 (sitespeed.io) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Welcome to the wonderful world of web performance!

Using sitespeed.io you can:

Run your custom-made JavaScript and collect whichever metric(s) you need.
Test one or multiple pages, across one or many runs to get more-accurate metrics.
Create HTML-result pages or store the metrics in Graphite.
Write your own plugins that can do whatever tests you want/need.

See all the latest changes in the Changelog.
