Setup an HTTP Server

GraphQL Yoga Example

import { createSchema, createYoga } from 'graphql-yoga';
import { createServer } from 'http'
 
const typeDefs = require('./graphql/types')
const resolvers = require('./graphql/resolvers')
 
createServer(
  createYoga({ schema: createSchema({ typeDefs, resolvers })
).listen(4000, () => {
  console.log('GraphQL Server is listening on http://localhost:4000/graphql');
})

And you can test your queries using built-in GraphiQL:
