RUM update: lux.js v301

25 April 2022

New features

• The synthetic onload time for SPAs can be marked with LUX.markLoadTime(), allowing LUX.send() to be called later in the page lifecycle.
• Added the SpeedCurve RUM Debug Parser to help interpret the debug messages.
• LUX.getDebug() now includes events that help to debug some metrics including LCP, CLS, element timing, and long tasks.
• Source maps are now available for lux.js.

Bug fixes

• Fixed a bug where JavaScript errors were only tracked on the first SPA page view.
