Did anyone else just get emotional going through this tutorial like how easy it has become to get data and not just data, i mean data that is relevant to the current scenario. Also the way he gets excited really kept me going. Thank you sir!!

[@Nectaroon]

You're a great teacher, Laith! Thanks so much for the hard work you put into these, they're incredibly helpful. I feel lucky to have found your channel!

[@junaidulqayyumqureshi7546]

As an extreme newbie in GraphQL, I can say, by GOD this is one of the best, most easiest and well-explained videos out there on GraphQL, if not the best. Hands down!

[@mvmanh]

I really appreciate the way you enlarge the UI and text size so that we can easily watch your video on mobile devices, even on a mobile phone. Thank you so much!

[@dancingdata2118]

Hey Laith ! Your tutorial is very nice and pretty clear! I do like the way you’re teaching and really appreciate for your contribution! Keep going!

Thank you Laith, I'm gonna start studying GraphQL in a month or so and probably, with your udemy course, it will be much easier

[@samiullahsheikh5015]

Awesome tutorial. You also explain what is happening and best practices too. Full learning package. Great work bro

[@akhilaravindakshan420]

You're the reason I get to learn, understand and become a great developer. I have a request, could you please make a tutorial on Webpack 5 and set a react project with Webpack manually for both dev and prod?

[@thongtech1984]

I am looking forward for this vid also

[@WillGains]

Just out of interest, why would you want to set it up manually when CRA, Next and Gatsby sort it for you?

[@gfgdgfdgdfhggjfjytjy]

Try

[@duynhanvo7673]

I love your explanation. It is so easy to understand. Thank you

Thank you for this, very vivid explanations. God Bless you🙏

[@denisslabodchikov342]

Thanks a lot, your video really helped me to understand graphQL

[@hazartilirot1014]

3:26:11 Once again mate! Mind syntax! updateCategory: (parent, { id, input }, { db: { categories } }) => categories[categories.findIndex(c => c.id === id)] &&= { id, ...input } - as you may notice, if findIndex returns -1 the whole expression will give us undefined. Thankfully, we've got an operator &&= which only assigns a value once the left side isn't null or undefined. Meaning, we would assign a new object to the a corresponding index OR return undefined which would be null in the schema. It's a classic oneliner which definitely easier to comprehend and read. What I really don't get.... is that why we need to supply all fields to update just one? GraphQL allows us to read just one field that's why it's great for but on the other hand when we update a field - we need to specify all fields. It's strange.

[@princeratna8688]

This is very helpful video and you have explained everything very clearly. Take love.

thanks for this course i really fall in love with graphql because of you, this course can be much better if it was with typescript instead of js, thank you bro for all yours efforts

[@laithacademy]

udemy course is in TS

[@frankchen3021]

I've been seraching for graphql tutorials. The documents aren't helpful, their small dummy project is not enough for me to understand. The other tutorials are all outdated. And then I came across your video, you really give detailed explanations that are helpful, thank you so much

[@oz9957]

Thanks, great and useful video

[@ugurkorkmaz7968]

thank you man. Realy!

[@lohishra4901]

Excellent tutorial, Just a tip , it could have been more useful if you could also include the N+1 db queries issue in graphql and how to resolve that.

[@alfbaez]

Brilliant! Thx for sharing your knowledge. Would you do a fresh version with connecting and saving consisting data into PostgreSQL?

[@laithacademy]

The full course has a section that does that

[@yuvalron6319]

Thank you for this great introduction to Graphql. I liked it, but I am a little confused about the real advantage of Graphql over REST. I thought that the whole idea of Graphql is to provide a highly flexible querying language that saves the need of explicitly predefining a whole CRUD stack for each and every type (entity) in our data, thus avoiding the verbosity and inflexibility of REST endpoints. But it seems that we end up explicitly defining all our queries and mutations for each of our types anyway, even when all they need is plain CRUD operations, as opposed to mapping our data (the schema) to our presentation declaratively and let a default generic stack do most of the work. I'd be curious to hear your thoughts on this matter, what is the advatage here over RESTful APIs and whether we really become more flexible or less verbose in this approach to querying data? Maybe there's a way to make these CRUD operations more generic and declarative?

[@NitinRanganath]

Definitely planning to get this one. You're a great instructor. Do you have any other topics planned too?

[@laithacademy]

Udemy courses take so long to make so I want to focus on the KZbin channel for now, but it'll definitely won't be the last one

[@NitinRanganath]

@@laithacademy Looking forward to it, I completely understand 😄

[@lebcit2225]

Hello Thanks a lot for your time and all your efforts Would you consider making a tutorial about GraphQL using Fastify and Mercurius ? Thanks again Have a nice coding day/night

thank you man

[@raihanmahmud4017]

Thank you so much sir

[@wolfgangtiefbrunner8412]

Thank you very much for the concise and excellent demo. In 2:50:00, what is the exact reason we can't delete?

[@vaibhavtyagi18]

Best tutorial

[@odoolabs1366]

At 2:44:05 there was not any server related mistake when you were executing Add review mutation first time , it was you just forgot to execute the addition command because meanwhile you start writing th select query in the other window . so select query didnot work you thought that its server restarted but actually you forgot to execute the addreview mutation .

[@Shuyinz]

Question! Should I buy your course in udemy to learn graphQL properly, or is it enough to learn from your KZbin crash course?

[@milon27]

please make next part like graphql middleware, protect multiple resolver or all resolver in a file.

[@hassanebendaoud4446]

thanks

[@ajayraja6636]

After Watching your video in Net Ninja about React Testing Library I am addicted to your Videos

[@sjnthp268]

can you please tell me which vscode theme are you using ? I really need that theme, I could not get those highlighter in my default vscode theme as shown in this tutorial in schema.js file

[@psymannizback]

Are you planning on making a React Native tutorial?

[@mickaelrichard7255]

hooooo yes! Not event watching the video directly buying your udemy course! Hope its not your last udemy course :)

[@nepalcodetv6298]

how would you deal with graphql disadvantage like: caching (redis), rate limiting ?

[@dylan-j-gerrits]

How can you provide the context that way ? I have to provide a function, and not in the constructor of the server but while starting the server...

[@iltanoia6865]

Hoping that you will include mongoDB connection in your udemy course

[@sofian_so]

Thanks for the course. I’m interested in buying your Udemy course but the couple no longer works..

[@gopinathkrm58]

Hi is it possible to integrate GraphQL along with Node JS template engine like EJS/PUG. Because in REST we can create dynamic html files based on the incoming route and after receiving the request we process it and send out html using render( ) But in GraphQL since there is only one endpoint how to send out dynamic html files based on the incoming route or we can only send the JSON objects ? I need to use GraphQL but with NODE + EJS - is this even possible ? or we can use it only with client side like React etc.. can you please give a simple example for this scenario ?

[@abdu5822]

Hey man, thanks for uploading this. one thing that bothered me in the video is the zooming (too zoom in), i think you went too far with the zoom. i believe 70% is normal. i hope you understand my point. Thanks Anyways.

[@souvikkumarbarua5557]

Can you make a video on graphql with php... On same content like this

[@includejoe]

This is a great tutorial but I feel like you could have done the database a little more practical with like using mongodb instead of keeping all the data in an object in one file.. once again great tutorial!

[@laithacademy]

I use a SQL DB in the full Udemy course

[@includejoe]

@@laithacademy that is great! I'll be sure to check it out

[@adriandrozman3404]

Any incoming content on microservices ? I really enjoy the Udemy course

[@laithacademy]

That's great to hear! I would love to do a microservices course sometime in the future

[@sammedsankonatti]

even in Rest we can select what we want right(select name , image from products that's it)? instead of over fetching. it all delepnds on SQL queries right? 9:36

[@dagoldfish6829]

Question, the GraphQL looks like a black box for me. How do I get a list of all available tables inside the GraphQL? Also How do I list all fields in each table? I am using SQL and not sure how to find the data inside the GraphQL quickly.

[@editingtuto1.011]

How to use schema Directives in Apollo V4. Can anybody explain to me how this will work through examples like role (Admin, user) to allow access to specific mutations/queries?

[@yashvanthkumar2576]

@Laith Harb , I have taken one of your Nextjs course in udemy While connecting a database getting this error. when i run the command > npx prisma db push Error: Migration engine error: db error: ERROR: prepared statement "s0" does not exist

[@Davi-wv8mi]

Tanks man you're the best, your kitty is hungry HAHAHHA

[@gordonfreimann]

2:12:33 -> with your logic if onSale is set to false it wont return products with onSale being set to false. because you only filter if onSale is set to true. Correct implementation should be if onSale !== undefined then filter ... product.onSale === filter.onSale. Justa small nitpick, otherwise great introduction, thanks

[@Jayakrishna-ly3ei]

35:58 wrote same code but getting error like this, TypeError: AppoloServer is not a constructor

[@notyournormaldev1419]

Is there is ui for ecommerce in this course?

[@fashq]

Hello everyone, around 2:50:27 Laith explains that we would not be able to delete anything unless we export a single object, can anyone explain this in more depth to me? I don't really understand the difference or what really changed. Thanks in advance.
