Creating your own components

Replace {{class-name}} with a CamelCase name and {{tag-name}} with the corresponding dash-separated name

import { LitElement, html, css } from 'lit-element';
import { styles } from 'wgnhs-common';

export class {{class-name}} extends LitElement {
  static get properties() {
    return {

    };
  }

  constructor() {
    super();
  }

  static get styles() {
    return [
      ...styles,
      css`
    `];
  }

  render() {
    return html`
    `;
  }
}
customElements.define('{{tag-name}}', {{class-name}});

Building

npm run build

The distributable folder dist/ can be generated by runnning npm run build

Publishing GitHub Pages

npm run pages

The command npm run pages will build the source code, and commit the dist/ folder to the gh-pages branch of the repository. It will also push the branch to the git remote named origin

Releasing

A baseline release process is implemented in npm scripts:

npm run release

The command will:

• install dependencies

• configure publishing options
• version to the next patch version
• push the newly created commit and tag
