Creating A GraphQL Server With Node.js And Express

[@seancpp]

I heard about graphql from the CodingBlocks podcast and this looks absolutely amazing. I can’t wait to get my hands dirty with this

[@CallumAtwal]

Thank you very much for this video! I've gone from 0 to having a good enough understanding on implementing a graphql API

[@billwindsor4224]

Excellent GraphQL server configuration tutorial here, with several query structures to show GraphQL query configurations; *thank you, sir!*

[@mussieteshome8232]

Clear and concise tutorial..thanks man!

[@werneralonzo1230]

great example, I was confused but now I very clear how graphQL works, thanks dude.

[@TheMezanine]

Thanks very much again for this awesome introduction to GraphQL!!!

[@EricBishard]

Excellent video, this is exactly what I needed to get familiar with GraphQL and Express! Such a great way to teach getting started...

[@أبوعائشةالشامي-ف7ر]

clear and clean as every time.....another awesome tutorial

[@r29Knight]

The best tutorial! Thanks a lot for the help!

[@amandaavelino8362]

[@mass13982]

Excellent demonstration...very clear explanation...Thanks

[@novanleon]

Excellent tutorial. Appreciate your excellent work.

[@RealToughCandy]

Love it! Nice video. Have been looking for a n00b's walkthrough on implementing GraphQL and this was perfect.

[@codingthesmartway]

Thanks RealToughCandy!

@@codingthesmartway Isn't it a sarcasm?

[@1123-p1y]

Very nice and easy to understand and follow.

[@ismailzafar]

Great Graphql Introduction video

[@kareemsaeed6562]

In minute 42:23 instead of using both map and filter to get the updated course you can do it like this:
const updateCourseTopic = arg => {
let id = arg.id;
let topic = arg.topic;
let updatedCourse;
coursesData.filter(course => {
if(course.id === id){
course.topic = topic;
updatedCourse = course;
}
return course;
});
return updatedCourse;
}
Where you are only using filter on coursesData array

[@menofculturehead9370]

nicely explained.. very well does the job!

[@mohsenmadi3590]

Thank you Sebastian for this informative primer on GQL! It's not hard to predict that it would/should replace REST easily specially in newly built apps.

[@daniellaerachannel]

great tutorial as usual

[@diwakarsingh9558]

Good explanation ... Nice video :)

[@_MrMiyagi]

Very Very good !

[@bennguyen1313]

Sorry, very basic question here.. so express.js runs on top of node.js.. but to use GraphQL you need another server, express-graphql? How does graphql-yoga or apollo-server-express fit in?
For example, 'npm install' is used to install node.js modules, yet things like graphql-yoga are installed using 'yarn'.. so I assume it's not running on Node.js?

[@otn987]

express-graphql is middleware for express, and express itself is nothing more than a frame work that makes your life easier than having to write server side code all from scratch. Node.js is an environment that allows javascript to run on a server.

[@tedspens]

Thank you for this excellent tut. GraphQL finally makes sense! :)

It helped me a lot, Thank you

[@gortee1000]

Great ! Exactly what am looking for in so many junks (y)

[@raosezar889]

for everyone have error express_graphql is not a function only change it to be like :
const { graphqlHTTP } = require("express-graphql");
and in app.use write like:
app.use(
"/graphql",
graphqlHTTP({
schema: schema,
rootValue: root,
graphiql: true,
})
);
I hope it helpful

[@iroekyjHD]

in the newer express-graphql package use ``` const { graphqlHTTP } = require('express-graphql'); ```
*edit* : also you will need an older version of graphql i think 15.3.0

[@chucknor9708]

Great video Sebastian. How would you extend this for an example where the data is not static and defined within the Server implementation but being called from a database? Thanks. Tam.

[@seancpp]

chuck nor
You can use an ORM at the resolver step. Nothing changes about how you store and retrieve data-graphql doesn’t care about that. It’s just replacing your rest api
If I’m wrong or mislead please correct me I’m very interested in this

[@sumantkanala]

Cool tutorial. Small suggestions would be use the shorthand object properties like: {schema, rootValue:...} instead of {schema:schema, etc...} which is redundant from ES6. Also replacing var with const is considered a good practice.

[@hamdimiled4836]

is possible to make Appllo like a controller in sequence diagram ?

[@stilesndife8291]

Thanks a lot brother. well explained

[@tentacle8148]

why do you use var?

[@faridbangash75]

sir how can we add different middlewares to graphql like isLoggedIn, hasPermission etc.

[@SunilKumar-fh6jk]

Hey sabastian, I have a request dude, please make a authentication tut using express graphql and react please. I'm stuck!

[@SunilKumar-fh6jk]

I'm waiting for your response

[@ahmedabdelfatah8967]

[@alexanderdimitrov3765]

"Unknow type int" error. Please help!

[@flaviokonti5522]

Capital I in Int

[@gabrielgitonga1252]

Quick update
Change this var express_graphql = require('express-graphql')
To var express_graphql = require('express-graphql').graphqlHTTP;

[@damiangilz]

Good video, but how do I get the result to display on the frontend?

[@迷彩网后]

I think this tutorial still need to add babel and better file organization

[@billwindsor4224]

@迷彩网后 Please clarify: "better file organization", be specific

[@kodakodu]

var root = {
message: () => {
return "Hello World";
}
