How to implement GraphQL APIs with Laravel?

composer require nuwave/lighthouse
php artisan vendor:publish --provider="Nuwave\Lighthouse\LighthouseServiceProvider"
php artisan lighthouse:publish-schema

# graphql/schema.graphql
type Query {
  posts: [Post!]! @all
  post(id: ID! @eq): Post @find
}

type Post {
  id: ID!
  title: String!
  content: String!
}

type Mutation {
  createPost(title: String!, content: String!): Post! @create
}


// routes/web.php
Route::get('/graphiql', '\Nuwave\Lighthouse\GraphiQLController@index');

# Test query:
# { posts { id title } }
