type graphql decorators

Custom decorators are a great way to reduce the boilerplate and reuse some common logic between different resolvers. TypeGraphQL supports three kinds of custom decorators - method, resolver class and parameter.

Extensions · TypeGraphQL

Annotating schema types or fields with a custom metadata, that can be then used at runtime by middlewares or resolvers, is a really powerful and useful feature. For such use cases, TypeGraphQL provides the @Extensions decorator, which adds the data we defined to the extensions property of the ...

I think you are trying to have an Arg of an array whit numbers and strings in that case you should do

@InputType()
class HitsInput
{
    @Field()
    Hits: [number | string];
}

@Resolver()
export default class SearchResolver {
  @Query(() => [String], { nullable: true })
  async searchAssetList(@Arg('input') input: HitsInput) {
    return []
  }
}

if this is not the case and you want an object whit dynamic fields you need to define the object, let say if hits have Name and Id_Hits,

@InputType()
class HitsInput
{
    @Field()
    Id_Hits: number;

    @Field()
    Name: string;
}

@Resolver()
export default class SearchResolver {
  @Query(() => [String], { nullable: true })
  async searchAssetList(@Arg('input') input: HitsInput) {
    return []
  }
}

and if you want to have a dynamic args base in the user request I am not quite sure that it is possible, but it is possible to do this

@InputType()
class HitsInput
{
    [key: string]: any;
}

I had exactly the same issue, a couple of days ago, and I solve it using GraphQLScalarType by creating my own custom type here how to do it

import { GraphQLScalarType} from "graphql";

export const GraphQLAny = new GraphQLScalarType({
    name: 'Any',
    serialize: (value) => value,
    parseValue: (value) => value,
    parseLiteral: (ast) => ast
});

and in your class you can use your customTpe like this:

@ObjectType()
class SearchListInput {
  @Field(() => GraphQLAny)
  hits: typeof GraphQLAny;
}

Introduction to TypeGraphQL

July 26, 2024 - In the above example, we define the GraphQL object type for a User using TypeScript classes, which enhances type safety and maintainability. Each field of the User object is defined with a @Field decorator, which describes the type of data (such as ID, String, etc.) and whether it is nullable or not.
