⚡️ App and Component Generator for Apollo Elements 🚀

🔎 Read the Full API Docs 🔎

To quickly get started with apollo-elements, generate a skeleton app with this command

npm init @apollo-elements

Which will prompt you to generate a full app, or a component thereof.

App Generator

npm init @apollo-elements -- app

Generate an Apollo Elements Skeleton App

Example

npm init @apollo-elements -- \
  app \
    --pkg-manager yarn \
    --uri '/graphql' \
    --install \
    --start \
    --yes

Options

Flag	Description	type	default
--help	Show help	boolean
--version	Show version number	boolean
--pkg-manager	Preferred package manager	npm or yarn	npm
--uri, -u	URI to your GraphQL endpoint	string
--yes, -y	Use default package.json fields (e.g. author, license)	boolean
--skip-codegen	Skip the codegen phase	string	false
--install, -i	Automatically install dependencies	boolean
--start, -s	Launch the dev server after scaffolding	boolean

🔋 Batteries Included

The generated app comes with plenty of bells-and-whistles:

• TypeScript
• Linting with eslint and an opinionated ruleset
• Buildless development workflow with @web/dev-server
• Minified production bundle
• A basic Apollo Client instance
• Simple, unopinionated SPA routing
• Code-generated TypeScript typings for GraphQL documents
• import MyQuery from './My.query.graphql'
• import styles from './my-element.css'

🛎 Scripts

These npm scripts help you get your work done in style:

npm start
yarn start

runs the code generator and the development server in watch mode

npm run build
yarn build

bundles the app into /build. The build will bundle and minify your javascript, and minify your HTML. Just upload to your static file host and you're good.

npm run lint
yarn lint

Lint your app with an opinionated set of rules for JavaScript and TypeScript

npm test
yarn test

The generator currently doesn't offer strong opinions on testing your UI components, so npm test currently exist with an error code. For unit testing business logic (i.e. typePolicies), we recommend @web/test-runner

Component Generator

npm init @apollo-elements -- component

npm init @apollo-elements -- \

    --type mutation \

    --subdir user \
    --schema-path '#schema' \
    --shared-css-path '#components/shared.css' \
