Your First Apollo Server

After installing the module, you are ready to implement for your authorization layer to your GraphQL server.

Initial Apollo Server

To show how to implement authorization, here is our first Book API application.

import { ApolloServer, gql } from 'apollo-server'
import { authDirective } from '../src/authz'
import { makeExecutableSchema } from '@graphql-tools/schema'
import { GraphQLFieldResolver, GraphQLResolveInfo } from 'graphql';

const typeDefs = gql`
  type Book {
    title: String
    author: String
  }

  input BookInput {
    title: String!
  }

  type Mutation {
    createBook (book: BookInput): Book
  }

  type Query {
    books: [Book]
  }
`;

interface Book {
    title: string
    author: string
}

const resolvers = {
  Query: {
    books: async (parent: any, args: any, context: any, info: any): Promise<[]Book> => {
      return [{title: 'Authentication and Authorization',author: 'Keke'}]
    },
  },
  Mutation: {
    createBook: async (parent: any, args: any, context: any, info: any): Promise<void> => {
       // Run DB query
       return
    }
  }
};

let schema = makeExecutableSchema({
  typeDefs,
  resolvers
})

const server = new ApolloServer({
  schema,
  csrfPrevention: true,
});

server.listen().then(({ url }) => {
  console.log(`🚀  Server ready at ${url}`);
});
