That would be a good use-case for pipes integration.
from graphql.
@partyka95 we don't need that, see microservices & websockets. you can use pipes with them already
from graphql.
ExternalContextCreator
has to be agnostic, meaning, we cannot adjust it to the GraphQL purposes. As a result, pipes won't be integrated with @nestjs/graphql
package. Instead, you can keep validation responsibilities in the business logic.
from graphql.
You'd just want to write some helper functions and then implement them in your resolver file
from graphql.
@kamilmysliwiec To use the pipes, we need a decorators like @Body(new ValidatorPipe()) in controllers, right? Do you have plans to create a decorator for resolvers like @Args()?
from graphql.
Could anyone give an example?
from graphql.
At the present time, it looks like pipes are loaded by the PipesContextCreator
, which is used by the "context creator" of RPC (microservices), WS (websocket) and Routes.
But Resolver
(from nestjs/graphql) uses ExternalContextCreator
(from nestjs/nest), which, at the present time, only uses the GuardsContextCreator
and InterceptorsContextCreator
.
It looks like the Pipes are set up between the Guards and the Interceptors and should be inserted around here in ExternalContextCreator
.
@kamilmysliwiec is it correct? Would it take a lot of work to me to create a PR? Or should we do something special for GraphQL Resolvers? (Like targetting body
in the rootValue (which is most likely req
, if everyone's following the documentation)?)
Thanks!
from graphql.
Any clearer examples on how to best implement validation for mutation inputs? Things like min/max lengths, advanced type fields etc. that we are used to from packages like class-validator?
