🔧 Installation

Apollo elements' fast 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 computer then run the following command in your project's root directory:

npm install --save @apollo-elements/fast

👩‍🚀 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, then define your component's template. Add an ApolloQueryBehavior with a query to automatically subscribe when your element connects.

import { ApolloQueryBehavior } from '@apollo-elements/fast';
import { FASTElement, customElement, html, when } from '@apollo-elements/fast';

import { HelloQuery } from './Hello.query.graphql';

import { not } from 'fp-ts/function';

type B = Binding<HelloQueryElement>;
const isLoading: B = x => x.hello.loading;
const hasError: B = x => !!x.hello.error;
const getErrorMessage: B = x => x.hello.error.message;
const getDataPropOr = (prop: string, or: string): B => x =>
  x.hello.data?.helloWorld?.[prop] ?? or;

const template: ViewTemplate<HelloQueryElement> = html`
  <what-spin-such-loader ?active="${isLoading}"></what-spin-such-loader>
  ${when(hasError, html`
    <h1>😢 Such Sad, Very Error! 😰</h1>
    <pre><code>${getErrorMessage}</code></pre>`)}
  ${when(not(hasError), html`
    <p>
      ${getDataPropOr('greeting', 'Hello')},
      ${getDataPropOr('name', 'Friend')}!
    </p>`)}
`;

@customElement({ name: 'hello-query', template })
export class HelloQueryElement extends FASTElement {
  hello = new ApolloQueryBehavior(this, HelloQuery);
}
