import {gql, ApolloServer} from "apollo-server"

const typeDefs = gql `
    type Query {
        greeting : String
    }
`
console.log(typeDefs)

Resolver

const resolvers = {
  Query: {
    greeting: () => 'Hello world',
  }
}

Query' must match the Query and greeting here must match the greeting in query

  const server = new ApolloServer({ typeDefs, resolvers});
  const serverInfo = await server.listen({ port:9000});
  console.log(`server is running on ${serverInfo.url}`)
