Overview

Molecule is a JavaScript library for building user interfaces using web components.

It provides several classes from which you can build your Custom Elements

• The Molecule base class. It is agnostic about your actual templatization and rendering function.
• MoleculeLit class which uses the standard functions from lit-html by the Polymer team.
• MoleculeLitExtended uses the extended rendering functions of lit-html.

Installation

The @moleculejs/molecule package can be installed using npm or yarn:

npm install --save @moleculejs/molecule

yarn add @moleculejs/molecule

Documentation

Examples

Let's start with a simple Example:

class HelloWorld extends MoleculeLit.Element {
  static get properties() {
    return {
      name: { type: String, attribute: true, value: 'John Doe' },
    };
  }
  render({ name }) {
    html`
      <div>Hello ${name}</div>
    `;
  }
}

customElements.define('hello-world', HelloWorld);

This creates a new Custom Element called hello-world, which can now be used anywhere in your application using <hello-world>.

This new element will also keep the property name in sync with the attribute name, meaning that the element will look like this in the DOM:

<hello-world name="John Doe"></hello-world>

If you change the attribute or the property, both will be kept in sync and the element will be rerendered.
