Apollo server lambda Handler

const { resolvers } = require("../resolvers");
const { schema } = require("../schema");
const { ApolloServer } = require("apollo-server-lambda");

//GraphQL server
const server = new ApolloServer({
  typeDefs: schema,
  resolvers,
  playground: {
    endpoint: "/dev/graphql",
  }
});

module.exports.handler = server.createHandler({
  cors: {
    origin: '*'
  }
});
