Thanks, Great video keep it up

Hey Michael, thanks for this video 🙂 Apollo Federation 2 is what I'm working on too. We can achieve sync communication between subgraphs. But, what about async communication? subscriptions are not supported AFAIK. The only thing I found on apollo docs is federation-subscription-tools. However, it's far from being a reliable solution & over complicating the scenario. Any idea for async communication? would be wonderful if we can do it in Nestjs environment. Cheers

Очень хороший туториал по GraphQL , спасибо большое)

Excellent! thank you very much for this!

Hi Michael, Is there a way for the subgraph to tell the supergraph to whitelist a query, I was trying to add a custom Directive (public) in the subgraph resolver on a query and wanted to check for that in the gateway and skip token auth for that query. But that is not working in Nestjs. Also on the apollo docs, It is mentioned that Introspect and query should never be used in production. So I'll appreciate if you can guide the public on the production setup of this too. Maybe adding other features on the gateway like dynamic configuration control, rate-limiting, Auth etc.

thank you. good one.

[@monawwarabdullah7438]

i started learning about microservices through your videos, now i am able to setup nestjs microservices with kubernetes and docker, can you make a video on best practices of building microservices with kubernetes ?

[@mguay]

My new Ultimate Nest.js Microservices course will cover this! Stay tuned for its release in May.

Great explanation, thank you

Hello Michael, or anyone who can help. My question is, can I replace the url with any public graphql api url that is accessible through graphql playground? Does the name of the service in the subgraphs array matter? Cause I keep getting this error message when I use a public graphql api url: Error: Couldn't load service definitions for "institutions" at (api url), what I'm doing wrong?

[@chiragprajapati6312]

hey, can you make a project using, Nestjs, MongoDB, graphql, microservice, Nextjs

[@mykhailopronin7350]

Man, it's amazing

[@ahmedmazendessouky1551]

thank you for this great video, I have a question how to exclude some routes that have @isPublic decorator in the auth context?

[@saadmeddah6914]

how to inject a laravel service into this gateway ?

[@EhsanMoallaee]

Hi, how to prevent graphql gateway fail if one of our subgraphs is down? how you handle this? This behavior(actually bug) is completely against the microservices architecture concept and seems apollo doesnt care about it!!

[@mohamedalali4364]

I know I’m late to respond to this, I had the same question in mind. Apollo Gateway doesn’t directly take care of this, however, from what I can understand, you’re actually able to use an external load balancer and have two instances of the same subgraph running under a load balancer and just share the load balancer URL to the gateway as a subgraph.

Thank you so much ✌✌👍👍👌👌🙌🙌🙏🙏😍😍

[@g-luu]

Thanks. Would like to see how nestjs plays with tRPC

[@mguay]

Good video idea. Thanks!

[@kamiar3001]

Is possible to have many-to-many relations in this video you were talking about one user having many posts, so one post belongs to one user, just imagine how it would be possible to have one post belong to many users, how GraphQL can handle it?

[@codingwithnipu]

can you solved the federation with subscription problem in code first?

[@adriandrozman3404]

Hello, any updates regarding your Udemy course? thanks!

[@mguay]

Stay tuned for its release in May!

[@adriandrozman3404]

@@mguay thank you,instant buy for sure!

@Module({ imports: [ GraphQLModule.forRoot({ driver: ApolloGatewayDriver, server: { cors: true, "cors:true is redline" "Type '{ cors: true; }' is not assignable to type 'Omit'. Object literal may only specify known properties, and 'cors' does not exist in type 'Omit'." what could be the cause of the error

[@hinogi]

NestJs updated apollo to server v4 so you have to use the express server cors option.

How did you resolve this issue?
