[@isaachome7375]

Thank you so much for all the hard work you put into the video. Truly appreciate it. Thank you again. Looking forward for GraphQl with spring security.

Simple and So useful. I will rate it the best GraphQL video. Thanks a ton.

Thank you so much for this video. I was able to create my 1st ever graphql api.

Merci Dan ! It was some good fun !

Thanks for this video Dan. I had 2 requests: Could you show how to correctly do BatchMapping and how to correctly build your own GraphQl Protocol handler other than the built in Http, WebSocket and RSocket handlers.

[@DanVega]

I can work on that first one for you but I have to ask... what would you need your own protocol handler for?

[@adityamparikh]

@@DanVega Thanks! We have our internal proprietary tcp based protocol. I am able to send the graphql request as a string and response back as a string. I am doing this by building a WebGraphQlRequest from the query string and passing it to the Autowired WebGraphQlHandler which of course is available only if I make my application a web application either servlet or reactive.

Hi Dan, again thanks for that session, it was easy to follow and I could see the requests being sent and received with the web client on my local host. As a GraphQL noob Iand as an old Spring grunt still wonder why would I expose the controllers to a GraphQL client. Why not using REST for the client calls ? What GraphQL adds that would be helpful to the client ? Why a client would want to send GraphQL requests instead of REST ones ? And in fact, can a client, that is known to send REST requests, also send GraphQL requests at all ? Thanks for the awesome effort of yours ! I shall continue in the series and hopefully start playing with AI on your sessions. Cheers, Stephane, France

Hi Dan, I now see your Up and Running with Spring for GraphQL blog post. It should probably answer these questions 🙂 Thanks !

Thank you so much

Hi Dan - can you show a single example to do crud operation using MySQL db

[@DanVega]

Thank you for the suggestion. I am getting that in my backlog.

Hello @DanVega, thanks for the tutorial. A question, how can we change the output field name from id to say coffe_id without changing the member variable name in java code. What is the solution if I want to customize the output field name and do not want it to be equal to java member varaible name.

[@am-oo5uu]

What if your input parameter of the mutation is a list of input objects? f.e. public createCoffees(ArrayList coffees){ // do something here}

[@Luke_uppx]

nice

Hi Dan, Im trying to create a graphQL Crud API with springboot and my problem is that i dont know how to pass an object as an argument of a mutation. I tryed to use an input object but i need de id of the object that is related with this one. type Endpoint { id: ID! name: String! doc: String! typeOP: String! nameOp: String! aplication: Aplication! } Is a ManyToOne relationship How can i create a Mutation (createEndpoint) passing only a endpoint that is supposed to be a Object getted from the frontEnd?¿

[@DanVega]

I just put together a simple example with both Scalar Types and Object Types. Can you ping me either on Twitter or through email and let me know a little bit more about what problem you're having. twitter.com/therealdanvega/status/1636430352385228805
