🔧 Installation

Apollo element mixins are distributed through npm, the node package manager. To install a copy of the latest version in your project's node_modules directory, install npm on your system then run the following command in your project's root directory:

npm install --save @apollo-elements/mixins

👩‍🚀 Usage

Here's an example that uses HTMLElement

import { ApolloQueryMixin } from '@apollo-elements/mixins/apollo-query-mixin.js';

class HelloQuery extends ApolloQueryMixin(HTMLElement) {
  constructor() {
    super();
    this.attachShadow({ mode: 'open' });
    this.shadowRoot.innerHTML = `
      <style>/* ... */</style>
      <p hidden>
        <span id="greeting"></span>
        <span id="name"></span>
      </p>
    `;
  }

  get data() {
    return this.__data;
  }

  set data(data) {
    this.__data = data;
    this.render();
  }

  render() {
    if (!this.data) return;
    this.shadowRoot.getElementById('greeting').textContent =
      this.data?.helloWorld.greeting ?? 'Hello';

    this.shadowRoot.getElementById('name').textContent =
      this.data?.helloWorld.name ?? 'Friend';

    this.shadowRoot.querySelector('p').hidden = false;
  }
}

customElements.define('hello-query', HelloQuery);

<hello-query>
  <script type="application/graphql">
    query HelloQuery {
      helloWorld {
        name
        greeting
      }
    }
  </script>
</hello-query>
