i really like this kind of slow type of teaching. highly effective for me😄

[mojtabaabasimoghadam]

this is clearly best explaination about GraphQLObjectType, thank you master

Bro, I found an error in your code. Might be it is raising due to library updating.

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

[MattDuarte]

My question is, how do you learn all of this to teach us.

[saradevanney]

Has this gone out of date? This is very different to graphql official tutorial. Why are we not defining type using 'type Book' { author: String! } etc, ?

Thanks for this video it really helped me a alot

Hey Ninja, why do you construct the schema programmatically ? What is the advantage instead of buildSchema and a root object, like in the examples of graphql.js doc ?

[ItalianVoid]

Is this out of date now? My schema followed from a 2021 book is much different

I was wondering, why didn't you use apollo-server for writing the schema?

Hi!
First of all thanks a lot for the time you spend on these tutorials, they're really helpful and really well explained.

I'm facing a problem with the schema...

I'd like to separate two schema in two different files to have a better organization in my code, but I can't figure out how to merge them together to insert both of them in the graphqlHTTP function.

I found something about mergeTypes from merge-graphql-schemas

here's few line...



// schemas/index.js

const userSchema = require('./user');
const bookSchema = require('./book');
const { mergeTypes } =

const schemas = [
userSchema,
bookSchema
];

module.exports = mergeTypes(schemas, { all: true });



//app.js

const express = require('express');
const graphqlHTTP = require('express-graphql');
const schemas = require('./schemas/index');

const app = express();

app.use('/graphql', graphqlHTTP({
schema: schemas,
graphiql: true
}));

app.listen(3333, () => {
console.log('Server is listening on port 3333');
})



I hope you can help me figure out how to help me to solve this...

Thanks in advance!

Please make tutorial on mongodb all topics beginning to advanced.

Is there anyway you can show what the schema file would look like as a .graphql file instead of a JS file? Thanks for the great tutorials!

[speculativesapient]

Does anyone know why we set-up the fields function as:

fields: () => ({...})

as opposed to:

fields: () => {...}

Why does the round brackets surround the curly braces?

[WesAkers]

Question about how we're importing / requiring: If you're going to use ES6 features for "destructuring", why not just use the ES6 imports statement? I.E., why not 'import {GraphQLObjectType, GraphQLString} from './graphql'' instead of the multiple require statements? Genuinely curious if there's a tradeoff in usage, or if it's just a stylistic thing and it doesn't matter, or what.

[AutisticThinker]

This is old and doesn't work with latest version of express-graphql, typescript, and imports verse require. :(

[ayushshekhar]

Which theme are you using in your IDE?

[andrienpecson]

Greate tutorial. Apollo server please?

[arturo]

Anyone else noticed that he's using only constants? hahaha
