From the project README

An excerpt from the repository, fetched Nov 13, 2026.

Read the project’s introduction
Web Components Web Components are a new browser feature that provides a standard component model for the Web, consisting of several pieces maintained in different places: Shadow DOM Most of the parts are now maintained in DOM Standard, called shadow trees. Some of the parts are still remained in this repository. See Issue #661 for the progress of upstreaming those parts from the partially out-of-date Shadow DOM document. Issues against the DOM and HTML Standard. Issues raised in this repository. The old issue tracker on W3C bugzilla, which is no longer used. Custom Elements Custom elements were upstreamed into the HTML Standard (and bits in the DOM Standard) and are maintained there. Issues against the DOM and HTML Standard. Issues raised in this repository. The old issue tracker on W3C bugzilla, which is no longer used. HTML Templates HTML Templates were upstreamed into the HTML Standard and are fully maintained there. CSS changes The CSS WG works on CSS Scoping and CSS Shadow Parts, which help dealing with shadow trees with various selectors. Various other parts of CSS and its object model are also impacted by shadow trees and directly worked on in the various CSS specificaions. Issues against the CSS WG repository. JSON, CSS, HTML Modules Successor to the abandoned HTML Imports, allows JSON, CSS, and HTML markup to be requested by a component. HTML Modules Spec work is being incubated upstream in whatwg/html (see PR). For new issues, please file against whatwg/html or here in w3c/webcomponents. See also the HTML Modules explainer, initial proposal, and earlier design ideas. Issues raised in HTML Standard Issues raised in this repository. Includes related issues for other potential module-types, such as CSS and JSON. Old issue tracker includes a few issues filed when the feature was first proposed. Please avoid filing new issues there. Issues Please file issues in the most specific repository possible, per the above issue pointers. (It's often not this repository.) Abandoned features: HTML Imports The current issue tracker. The old issue tracker on W3C bugzilla, which is no longer used. Note: HTML Modules are intended to replace HTML Imports (see above).

Someone has made this more idiomatic to the spec: https://github.com/tmpfs/trucks. FWIW, we are looking at decoupling Incremental DOM in a way where custom renderers can be created, so one could create a <template /> renderer. It's not immediately obvious, but you could create a custom element with Skate that takes it's content and creates a new custom element definition from it, similar to how Polymer 1 worked. This approach was discussed as being implemented in custom elements v2, but is closed to see what frameworks come up with: https://github.com/w3c/webcomponents/issues/136. This is totally something that could be done with Skate, though.
In Show HN: SkateJS – a cross framework web components based library
I think so. At this point all browsers are on board with shipping Custom Elements and Shadow DOM and Template has already shipped everywhere. The holdout is HTML Imports and the Chrome team is currently working on a revision to that spec to build it on top of the ES2015 module loader so it's not contentious (https://github.com/w3c/webcomponents/blob/gh-pages/proposals...). But HTML Imports is not a requirement for Web Components, the big win is Custom Elements, so seeing everyone get on board with that is awesome :)
