Whats up Marius! There has been big changes in NestJS GraphQL. The GraphQL library is now a plugin which means you can use Mercurius instead of Apollo.

Do we need circular dependencies? Isn't it something we should avoid? I mean if you also would like to query owners with their pets, we have to have a circular dependency. Owner service needs pet service and pet service needs owner service, right?

If you can avoid it you probably should, but like you mention there are cases where you can’t avoid it when the relationships of your data are naturally circular. There is a documented way to resolve this in Nest, see: docs.nestjs.com/fundamentals/circular-dependency

Not a simple answer, because every job is different. However generally you need to have backend development fundamentals.. Nest is just a tool to help with that. Understand how to create basic REST APIs and how to do CRUD with a database… that is pretty much the main thing. Beyond that depending on your job there maybe other skills like validating requests, auth and maintaining user sessions, working with files (e.g. download/upload), caching, scaling & performance, security, etc.. However most of those things you can also learn on the job, as needed

I mean what your transport layer is between services or how you do it is up to you based on your own requirements I’m not sure I can answer that for you. Nest however has support for both request-response and event-based models, which should cover most typical use cases… e.g. I would imagine your queues by design won’t respond right away so communication via events probably makes sense

Is there a way to generate Swagger documentation off GraphQL Schema? If yes, can you create a tutorial for this? Awesome tutorial by the way!!

@mariusespejo

3 жыл бұрын

Thanks! You wouldn’t really typically use swagger for graphql, instead you’d use something specifically designed for graphql like the playground. You need something that allows you to explore the schema, as a form of documentation, and I don’t think swagger would be good for that purpose. It’s more for traditional rest APIs where you’d instead explore endpoints rather than one big schema

@mariusespejo

The Int is representation of the Scalar type for graphql. In javascript there isn’t really an “integer” type only number, so we’re basically saying that Int scalar in the graphql model maps to a number type in javascript. Hope that helps!

helo, this is a good video to get start on nestjs with graphql, when i keep move on, i try to do pagination in query. is there any tutorial can know more on it?

@mariusespejo

2 жыл бұрын

I don’t think I have one myself but it really mostly requires two things: one is you need to know how to do pagination with your ORM/database, for example with typeorm you can use limit/offset properties in queries. Two is you need to know how to add additional params to your graphql query request (basically inputs) which I believe I did cover in this video. You would basically need to have inputs for page/limit and feed that into the ORM query limit/offset

Epic video, thanks so much! Is there any way to use the entity model when creating the input type? Sort of like in Typescript you can do Pick, or Omit? There seems to be a doubling up of declaring the fields in the entity and input type that is not so DRY.

@mariusespejo

2 жыл бұрын

Yup there’s support for something like that, take a look at mapped types: docs.nestjs.com/graphql/mapped-types But also something to think about, while there is some duplication, the input type and the entity have somewhat different concerns, e.g. the input types can be utilized for validation

In your example you were able to show the owner data when querying for a pet. How do you implement this for the other way around? I tried exporting PetsModule and importing in OwnersModule to do a Pet search via OwnerId via PetsService but I got a "A circular dependency between modules." error.

@mariusespejo

3 жыл бұрын

Nest has docs on how to deal with circular dependencies: docs.nestjs.com/fundamentals/circular-dependency The other alternative is to simply add the other entity to the module, for example if you had: “TypeOrmModule.forFeature( [ Owner, Pet ])” in your module, then the service within that module can inject the repository for both entities without relying on a module dependency. Although in theory if you were utilizing relations properly (for example with the find API) I don’t think you even need to do any of that, e.g. you should be able to do something like: this.ownersRepo.find({ relations: [‘pets’] }); // returns owners with their pets That should work if all you need is to read/join the relation. I believe that’s covered in my video here
