Helix RUM Enhancer

> Add advanced functionality to Helix RUM Collection (client-side)

Status


Usage

This library is meant to be used in conjunction with and loaded by the sampleRUM function found in Helix Project Boilerplate or Helix RUM JS.

It will add following new checkpoints:

- cwv: Core Web Vitals Collection
- pagesviewed: number that helps to estimate how many pages are seen in average by a user.
- click: A click anywhere in the document
- viewblock: A Helix block has been scrolled into the viewport
- viewmedia: An image or video hosted by Helix Media Bus has been scrolled into the viewport
- reload, navigate, enter: depending on how the current page was accessed
- formsubmit: when a form is submitted

The source parameter is a string that can be used to identify the source of the event. It can be used to identify the source of the event, e.g. a button, a link, a form, etc.
It represents an idealized CSS selector that is both human-readable and specific enough to identify the source of the event in the document, even when not having access to the
orginal document. It is idealized because it pretends the DOM would use modern HTML with concise semantics, even if the actual document uses class values for things that would
be better represented by semantic HTML elements.

The sourceSelector function is a function that takes a DOM element and returns a descriptive source parameter. If the element has a data-rum-source attribute, its value is used as the source parameter. Otherwise, the function tries to generate a source parameter based on the element's tag name, class names, and text content.

The structure of the source parameter is as follows:

``
#
`
All three parts are optional

context is
- form for form elements
- dialog for dialog elements, or parent containers that are fixed positioned and have a positive high z-index
- .block-name for Helix blocks
- header, footer, nav, aside for main site structure
- #id as a fallback, if a container ID is available

element is
- button for buttons, or links that look like buttons (e.g. with a class button or btn or cta)
- img for images
- video for videos
- a for links that are not buttons
- input[type="text"] for input elements (all types are supported)
- select, textarea, etc. for other form elements

identifier is
- the id attribute of the element, if provided
- the first .class if there are any
- else omitted

Even if an identifier is provided, having a context and element is recommended, as it makes the source parameter more readable and easier to understand.
