Описание: Learn how GraphQL empowers more flexibility into your APIs – and learn to build GraphQL APIs with Apollo Server! You'll create GraphQL Schemas using scalar types, object type, queries and mutations. Then create resolvers to fullfill the data. Use interfaces and unions. Finally, add authentication to lock down resources.
