thank you, thank you, thank you. Aurelia is an excellent system for this exact use of a web component.

My example was "plain" custom elements, nothing to do with Aurelia.

Last I checked Aurelia used a lot of the Web Components terminology, but didn't actually create or use custom elements. Did that change?

[kensign]

yes

[spankalee]

So Aurelia components are web components? I can create one with document.createElement('my-aurelia-component'), and container.appendChild(), and the element will fully work and have it's lifecycle callbacks called?

I tried to look in the documentation, but couldn't see this clearly stated. It looked like Aurelia would have to be in charge of lifecycle to get dependency injection to work. Specifically, custom element constructors are called by the browser with no arguments: how does this work with Aurelia components that expect to receive constructor arguments via dependency injection?

[kensign]

that work is handled by Aurelia itself. You don't explicitly need to define the element.

Sorry, I still don't get it. Take the CustomerDetail example in the "Component Instantiation Through Dependency Injection" section:

    @inject(HttpClient)
    export class CustomerDetail {
      constructor(http) {
        this.http = http;
      }
    }

If this really creates a Web Component, how does `this.http` ever get set? The browser will call the constructor with no arguments.

What exactly gets passed to `document.registerElement()` (for the v0 Custom Elements API) or `customElements.define()` (for the v1 Custom Elements API)? Are you saying that Aurelia generates and registers a separate custom element class? That's not in the docs. If so, how does that element find the instances to inject into the user-defined constructors?

The main issue that talks about custom element support is still open, and the answer really does seem to be that Aurelia can't create custom elements: https://github.com/aurelia/framework/issues/7

This unfortunately seems to confirm that Aurelia uses the terminology of Web Components, but doesn't actually use or create real Web Components.

[kensign]

yeah... You might want to try it out and read the docs before you make such claims
