Yup, my issue was the the HTTP in my graphqlHTTP import was lower case.
Changed it to

const graphqlHTTP = require('express-graphql")

Thanks to both of you guys

will you please add subscription as well in your code

Thank you, great article.

Getting an error that I'm not sure how to resolve

when I run npm start in the terminal, it throws this error

TypeError: graphqlHttp is not a function

Here's my code

const express = require("express")
const graphqlHttp = require("express-graphql")
const mongoose = require("mongoose")
const graphqlSchema = require("./graphql/schema")
const graphqlResolvers = require("./graphql/resolvers")


const app = express()


app.use(
"/graphql",
graphqlHttp({
schema: graphqlSchema,
rootValue: graphqlResolvers,
graphiql: true,
})
)

const { graphqlHTTP } = require("express-graphql");

app.use(
"/graphql",
graphqlHTTP({
schema: buildSchema(`

I think the import should have graphqlHTTP wrapped in curly brackets

Wait, I was think about that wrong. Yes, looking at the documentation on npm, it does simply show putting curly brackets at the import. However, I'm still getting the same error. Still looking into.
Thanks for your answer btw

Sorry, not 100% sure where you mean by at the import.

yeah, I meant const {graphqlHTTP} = require("express-graphql")
what is the error you are getting now?
Also, check that that HTTP should be all caps in graphqlHTTP instead of graphqlHttp

Cool
