[GraphQL] apollo-server와 express 연결하기

apollographql/apollo-server

 

const express = require('express');
const { ApolloServer, gql } = require('apollo-server-express');

// Construct a schema, using GraphQL schema language
const typeDefs = gql`
  type Query {
    hello: String
  }
`;

// Provide resolver functions for your schema fields
const resolvers = {
  Query: {
    hello: () => 'Hello world!',
  },
};

const server = new ApolloServer({ typeDefs, resolvers });

const app = express();
server.applyMiddleware({ app });

app.listen({ port: 4000 }, () =>
  console.log(`🚀 Server ready at http://localhost:4000${server.graphqlPath}`)
);

 

나는 원래 'apllo-server'에서 ApolloServer를 import 했었는데,

server.express.use를 써보려 하니까 안돼서

'apllo-server-express'에서 ApolloServer를 import하고, app.use를 쓰니까 됐다!
