Code Editors & IDEs

CWCO is just HTML and if you want syntax highlighting for VSCode you can use the inline-html


For syntax highlighting of HTML and CSS in javascript use inline-html or lit-html plugins.

You can import html from cwco which is just a help for VSCode which does nothing special to the HTML string you use it with.

import {html, css, WebComponent} from "./cwco";

class MyButton extends WebComponent {
  get template() {
    return html`<button><slot></slot></button>`
  get stylesheet() {
    return css`<style>button {color: #222}</style>`
    // or 
    // return css`button {color: #222}`

Jet Brain IDEs

These IDEs have built-in HTML-in-Javascript syntax highlighting which can be useful when developing CWCO web components.
