Build GraphQL Microservices With Nest.js & Apollo Federation 2

This video shows how we can quickly build GraphQL microservices using the Nestjs GraphQL module and Apollo Federation 2 to stitch together multiple schemas.

Thank you Michael. I had a big project and I had to do with microservices and your tutorial helped me a lot!
God bless you man!

Очень хороший туториал по GraphQL, спасибо большое)

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 ?

Great video, well explained

Thanks for sharing

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 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

Excellent! thank you very much for this!

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

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.

how to inject a laravel service into this gateway ?

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?

[ahmedmazendessouky]

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

Thanks. Would like to see how nestjs plays with tRPC

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?

[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!!

[learncodingwithnipu]

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

Hello, any updates regarding your Udemy course? thanks!

what could be the cause of the error

Hi Sir, I've encountered an error throw Error( ^ Error: A valid schema couldn't be composed. The following composition errors were found: Non-shareable field "User.id" is resolved from multiple subgraphs: it is resolved from subgraphs "posts" and "users" and defined as non-shareable in subgraph "users" at
