问题 I have a class that extends HTMLElement . From reading this thread https://github.com/Microsoft/TypeScript/issues/574#issuecomment-231683089 I see that I can't instantiate a custom element with out getting a Illegal constructor . Additionally, the registerElement looked promising as it returned the constructor for the custom element but that is now deprecated for using CustomElementRegistry.define() that 1. exists on the window object and 2. returns void. Any solutions will be greatly

问题 I'm currently experimenting with StencilJS to create some web components. Now I know that there is <slot /> and named slots and all that stuff. Coming from React, I guess slot is similar to children in React. You can do a lot of stuff using children in React. Things I often did: Check if any children are provided Iterate over children to do something to each child (e.g. wrap it in a div with a class etc.) How would you do that using slot/web components/stencilJS? I can get the Host Element of

问题 While developing a Vue web component, the style is not applied to the web component, but added to the head of the document. This means that the style is ignored in the shadow DOM. Here is how I wrap the web component in main.js: import Vue from 'vue'; import wrap from '@vue/web-component-wrapper'; import MyWebComponent from './components/MyWebComponent'; const WrappedElement = wrap(Vue, MyWebComponent); window.customElements.define('my-web-component', WrappedElement); Again, any CSS rules

问题 Given three @angular projects all using v6.1.9: host , alpha , and beta alpha and beta create and define a web component each using @angular/elements as such: constructor(private injector: Injector) {} ngDoBootstrap() { const config: NgElementConfig = { injector: this.injector }; const component= createCustomElement(component, config); customElements.define("alpha-component", component); // beta-component respectively } alpha and beta are built using ng build --prod --output-hashing none and
