How do I tap into connected / disconnected lifecycle methods ?

[mykulyak]

Hi,

I am writing an element wrapping Monaco editor (+ doing extra stuff related to my app).
To set up the editor I need somehow to hook into 'connectedCallback'. However, I don't see a possibility to do this.

Can you guide me ? Here's the "more or less" what I'm trying to achieve.

Every property supports connect() callback, which is triggered within the connectedCallback of the Custom Elements API.

You can try to do something like this:

{
  tag: 'my-monaco-editor',
  editor: {
    value: undefined,
    connect: (host, key) => {
      host[key] = host[key] || monaco.editor.create(host.render().querySelector('div'), {
	value: ['function x() {', '\tconsole.log("Hello world!");', '}'].join('\n'),
	language: 'javascript'
      });
    },
  },
  render: () => html`<div></div>`,
};

I am not sure if I can help more in that subject. There is also an explanation of the concept in the docs here: https://hybrids.js.org/#/component-model/structure?id=connect

Feel free to re-open if you need more help.
