A lot of tutorials on tech topics fly over the "obvious stuff". I really appreciate that you take the time to go into the details of each step but remain concise. Great video thanks.
Just finished reading a book yesterday about creating REST API in .Net core, and now youtube algorithm bring me to the author himself. conclusion: this guy is a superb teacher!
One of the best tutorials I’ve seen. Coming from zero knowledge of graphql I feel at least now I understand the concepts backed by hands on examples. Thank you. Count me in as a new subscriber.
There is no doubt that this is the best tutorial out there. Thank you so much Les for also taking the time to explain the things clearly. You just gained a new subscriber.
I have just completed this video and can confirm this was such a great introduction to GraphQL, thank you so much! I agree with another commenter that another video on the advised or suggested ways to query this new API from a frontend perspective would be great too. Thanks again!
For someone who is doing this app in dotnet 7 and has errors after creating the PlatformType, you need to put the [Parent[ attribute in front of the GetCommands method from the Resolvers class. This is a breaking change in the framework of HotChocolate
Hi Les, thanks for this great course! I didn't finish it yet, I'm on my way :). I would like to mention one thing I found when running a profiler for sql server: when using ObjectTypes (for Platform and Commands) and doing the heavy lifting manually, there are three queries executed against the database (one per platform id). But if I use the default behavior, there is only one. I think that's worth noting. Thanks!!
Very easy to understand, great voice, great visuals and great pace! Overall, a very good tutorial that is easy to digest and very much worthwhile going through. I only had one slight issue when I couldn't get Voyager to work, other than that every part was flawlessly explained and shown!
if you are using package GraphQL.Server.Ui.Voyager Version="5.0.1" or higher the following should help: using GraphQL.Server.Ui.Voyager; public void Configure(IApplicationBuilder app, IWebHostEnvironment env) { ... app.UseGraphQLVoyager(new VoyagerOptions(){ GraphQLEndPoint = "/graphql" }); } default voyager endpoint is "ui/voyager" cheers.
@@toddnedd2138 This does not work for me. But this: app.UseGraphQLVoyager(new VoyagerOptions(), "/graphql-voyager"); You can also omit the path. Then the GraphQL Voyager is accessible via its default: /ui/voyager
This is Superb Tutorial, Well presented . Les hat off to your effort and passion in teaching every bit of details in such a structure and easy format. I loved this video and have become fan of your channel. Keep up the good work . Many thanks
For someone struggling with the voyager setup, this is how it worked for my version of 5.0.2: app.UseGraphQLVoyager(new VoyagerOptions() { GraphQLEndPoint = "/graphql", }, "/graphql-voyager");
i'm not a dotnet developer but i was thrown headfirst into it cause of work, ur videos on it and the way u explain things really helped me a ton! i just wanna say thanks for making them ~!
Les, Thank you so much for your informative tutorials. I did the one on API and Microservices and now GraphQL API and they are so helpful. Your teaching style is great and I have learnt a lot from you.
subscriptions blew my mind. and also i am very opt in to the idea of starting type-less. after agreeing on the basics with the business representatives, one can quickly provide added complexity. kudos man. thanks for all the effort you put on this.
Amazing tutorial, thank you! What would be awesome is to include a section (or a separate video) on how to handle authorization in GraphQL (both "endpoint-wide" and also user by user/object by object). I know it's a whole different complex can of worms and lots of work, however that's the last piece of info for me to be able to "ditch" REST :) Any chance you would be up to something like that?
This is quality work. It's sat in my list for the last year and I finally got around to watching it since I'm starting to mess around with GraphQL and it's still pretty helpful even though I'm not using Hot Chocolate
I was getting errors using the ResolveWith in the two Type classes, what fixed the issue was adding the [Parent] decorator to the first argument in the two Resolvers classes. public Platform GetPlatform([Parent] Command command, [ScopedService] AppDbContext context) and public IQueryable GetCommands([Parent] Platform platform, [ScopedService] AppDbContext context) Hope this helps anyone doing this currently. This is with HotChocolate version 12.0.1
Hi @@binarythistle. I noticed that GraphQL.Server.Ui.Voyager version 5.0.2 does not have option of new GraphQLVoyagerOptions() in the Configure method in Startup.cs. I had to use the version you;re using
Hi Les! Love your voice, your beart, the accent and the way you're teaching us all that interesting stuff! Keep up your good work! For me it is "learning with a smile" and makes it easier then elsewhere! Greetings from Hamburg to Melbourne!
I love graphql but having done work with graphql.net hot chocolate is far better and I did a demo with a legacy app and got up and running in a day I love banana cake pop as the testing and info ui. Its definitely something I will be promoting. Thank you for your videos it helps so much
I love your tutorials. Thank you for sharing this quality videos for free here. Actually you are helping me a lot with my APIs and I am falling in love with the backend part of programming!
Thank you Les, this is awesome, your step by step tutorial is really precise as you type while you going along. I have learned a lot and I like GraphQL.
Great, wondeful, easy to absorb and understand topic. I love your method of training others. I think it would be great if you show at the end for 10 minutes how to call all those GraphQl services (Platform, Command) from a .Net client or an asp.net mvc web page, that would be great if you can add this part, well done and thanks for making this available for the community.
@@KittFanNr1 I googled but was not able to figure it out for this code, they were all specific and not similar to what Les showed us, maybe he can help us with a 15 minutes video if he has some availability :-)
Excellent video had to google a breaking change in the HotChocolate 12 update in the Platform and CommandsTypes code, but this is a minor issue. I have implemented Dataloaders which I definitely recommend. Great Job! Thanks!!
Tip: If you add a 00:00 time code in your description, then youtube will automatically add chapters to the video.
Did not know this. Great tip.
A lot of tutorials on tech topics fly over the "obvious stuff". I really appreciate that you take the time to go into the details of each step but remain concise. Great video thanks.
This has to be one of the best tutorials I have ever watched. Thanks for putting it together!
i Agree!
Couldn't agree more
I love his tutorial! His teaching mannerism is so assuring and easy to follow. Best instructor ever!

What's the name of the book brother..?

The Most effective Tutorial I have ever seen on GraphQL. I was thinking of buying a tutorial in Udemy. Now I think I don't need it. Thanks a lot
Outstanding tutorial. Love how you hand code everything instead of magically pasting in code.

Currently we are switching our tech stack and your videos are pure gold. Thank you very much
This was incredible. Thank you for such detail. This is the only example I've found that walked you through end-to-end. It was perfect!
Welcome back bro! Keep up the awesome content! You're a great teacher.
I have not seen such a detailed video on GraphQL. Trainer knowledge is very good.
I just want to say: This is awesome!!!
Always enjoy your all tutorials !!!!!!😀

For someone struggling with the voyager setup, this is how it worked for my version of 5.0.2:
app.UseGraphQLVoyager(new VoyagerOptions()
{
GraphQLEndPoint = "/graphql",
}, "/graphql-voyager");
Thanks for this - the "Path" property also doesn't exist, it seems to be set as default to this:
- localhost:5000/ui/voyager
THANKS! I burned an hour on this and could not move on.
Thanks
Thank you for this!
I guess the now supposed way is:
after
endpoints.MapGraphQL();
insert
endpoints.MapGraphQLVoyager("/graphql-voyager");
Finally a guy who is happy with 2020!

Got the same, thanks !
