In My approach to HTML web components Jeremy Keith goes into a naming convention for both web components and their attributes.
While I don’t have any opinions on attribute naming, I do have a strong opinion on element names, and that’s if you decide to namespace your elements it should be done using a post-fix and not a pre-fix.
As an example, all the elements we’ve build in Skia Infra are post-fixed with -sk:
https://jsdoc.skia.org/theme/theme-chooser-sk-demo.html [Source]
checkbox-sk
collapse-sk
error-toast-sk
icons-demo-sk
multi-select-sk
nav-button-sk
nav-links-sk
radio-sk
select-sk
spinner-sk
styles
tabs-panel-sk
tabs-sk
toast-sk
This is in contrast to prefixing, which makes the names much harder to read, such as all the iron- elements
in Polymer:
https://www.webcomponents.org/collection/PolymerElements/iron-elements
iron-image
iron-selector
iron-localstorage
iron-label
iron-collapse
iron-checked-element-behavior
iron-demo-helpers
iron-scroll-target-behavior
iron-a11y-keys
iron-form-element-behavior
iron-meta
iron-media-query
iron-validatable-behavior
iron-pages
iron-jsonp-library
iron-ajax
iron-list
iron-doc-viewer
To me the former are much easier to read, while the latter just reads like “iron iron iron iron” when used on page.
