    πŸ”§ Installation

    Apollo Elements' lit-apollo is 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/lit-apollo

    πŸ‘©β€πŸš€ Usage

    See our docs on setting up Apollo client so your components can fetch their data.

    First, let's define our component's GraphQL query.

    query HelloQuery {
      helloWorld {
        name
        greeting
      }
    }

    Read our docs on working with GraphQL files during development and in production for more info, and be sure to read about generating TypeScript types from GraphQL to enhance your developer experience and reduce bugs.

    Next, we'll define our UI component. Import the base class and helpers, query, and types:

    Imports
    import { ApolloQuery, html, customElement } from '@apollo-elements/lit-apollo';
    
    import HelloQuery from './Hello.query.graphql';
    
    import type {
      HelloQueryData as Data,
      HelloQueryVariables as Variables
    } from '../codegen/schema';

    Then define your component's template. Make sure to set the query field, so your component starts fetching data automatically.

    @customElement('hello-query')
    export class HelloQueryElement extends ApolloQuery<Data, Variables> {
      query = HelloQuery;
    
      render() {
        return html`
          <what-spin-such-loader ?active="${this.loading}"></what-spin-such-loader>
        ${(
          this.error ? html`
            <h1>😒 Such Sad, Very Error! 😰</h1>
            <pre><code>${error.message}</code></pre>`
        : html`
            <p>
              ${this.data?.helloWorld.greeting ?? 'Hello'},
              ${this.data?.helloWorld.name ?? 'Friend'}!
            </p>`
        )}
        `;
       }
    }
