custom-elements-manifest VS catalyst

The Web Components Community Group is developing such a format to describe the types of components here: https://github.com/webcomponents/custom-elements-manifest

People have already built tools that generate wrappers based on it.

TL;DR: A Custom Elements Manifest is a JSON file that contains all metadata about the custom elements in your project. You can read all about it here.

Custom Elements Manifest is a file format that describes the custom elements in your project. This format will allow tooling and IDEs to give rich information about the custom elements in a given project. A custom-elements.json contains metadata about the custom elements in your project; their properties, methods, attributes, inheritance, slots, CSS Shadow Parts, CSS custom properties, and a modules exports. If you're interested in following the specification of the schema, or contributing to it, you can find the repository here: webcomponents/custom-elements-manifest.

Reminds me of GitHub catalyst web component framework, which has targets & actions. https://github.com/github/catalyst

Working on the next Web UI (TypeScript + Catalyst).

Catalyst (opt-in via CLI flag)

They actually use a web component system, with a library called Catalyst used to make things a bit easier. They aren't simply doing raw DOM manipulation in Vanilla JavaScript, they're using components and what is essentially a fairly lightweight framework.

Personally, I'd really like to see the unmolested, with-dependencies versions[1].

This version is VERY easy to ship and adopt. But in my mind, these components hide how the sausage is made! Many were built with a library (Catalyst[2]), but the tools were obfuscated out in these end products.

There's a huge amount to be said for these web components. We need more models like this. But I also think there's an opportunity lost here, to teach, to inform, to help others learn how to build components, using the tech Github actually used to develop them.

GitHub Catalyst is a library that makes it easier to develop Web Components.

The only real escape is using something like /r/webcomponents. I did some playing around with Github's new Catalyst framework over the holidays, quite enjoyed it. But you'd be one of the only people on the planet using it. Stick with whatever works for you.
