custom-elements | A polyfill for HTML Custom Elements v1 | Form library

Per the Vue docs, it's possible to build components in Vue (v3) and package them as native Web Components for use with any framework or none at all.

As I've already found, the gap between design models for Vue components and Web Components can make this complex and sometimes a straight-up bad idea (at what point is it better and more maintainable to just go ahead building fully-native components?)... But let's assume for a moment that it's necessary here.

My question - What's the best way to expose a function-like interface on a Vue-built Web Component (to parent nodes)?

The Vue doc discusses passing in reactive data via props/slots, and publishing CustomEvents from the components, but I don't see mention of taking function calls (or at a stretch, events) from outside. As far as I can tell this is a pretty strong assumption that data and event flow on the rest of the app/page works in a very "Vue-like way"?

I am trying to format my css so there's no more than one empty line between lines, but i don't want that to apply to comments. The documentation for stylelint has a secondary option that should make this easy, but for some reason it isn't working. Here's the rule:

gatsby.js v4.4.0

I want to set up a script tag. However, I get an error and cannot set it up.

Please tell me how to install it.

In JointJS documentation (link below), I am able to define a simple custom element that is driven from other basic elements such as Line, Rectangle, Link, and so on https://resources.jointjs.com/tutorial/custom-elements

What I am trying to accomplish is to create a Group (custom element) that consists of a label at the top, and then a number of compartments aligned vertically beneath that label. A compartment itself acts as a container, which can contain a complete sub diagram, which itself can have other Groups, and so on.

I get how to create the label, but I am struggling to find out how to create the compartments as per the description above. All examples I am able to find so far are for simple custom elements that add additional attributes to the extended base elements.

I'm creating some basic elements in Stencil for a custom design system. I created some basic components, which work fine on their own as custom elements, but throw errors when used as React components.

I generated the React components via Stencil by includng the @stencil/react-output-target in stencil.config.ts.

I am trying to create a basic web component in Angular with Angular Elements.

So far, I have done the following:

1. Installed Elements using npm i @angular/elements --save
2. Installed npm i @webcomponents/custom-elements -- save
3. Added CUSTOM_ELEMENTS_SCHEMA to schemas array in app.module.ts
4. Created the component, call it MyComponent
5. Defined MyComponent as a custom element in AppModule using the code below

I already add this to my package.json dist/custom-elements/index.mjs": "dist/custom-elements/index.js why i am having this error (below). did i miss something?

The code is from this page https://usefulangle.com/post/362/custom-elements It builds a custom html form element with shadow DOM.

But, when I open it in a browser, it's blank.

I opened the code in "Inspect" and saw this error.

I use new future defineCustomElement from vue version 3.2.

Code main.js:
