Just a random question about graphql. Does anyone have a best practice or a method/library they prefer to use for validations beyond the types setup in the schema? A quick google search and I found https://github.com/profusion/apollo-validation-directives which looks interesting

curious about this as well

I didn’t set it up but we’re using

type-graphql

and

zod

to make our own Decorators:

import { ArgumentValidationError, createMethodDecorator } from "type-graphql";
import { z } from "zod";

export function ValidateArgs(schema: z.ZodSchema<any>, argName?: string): MethodDecorator {
    return createMethodDecorator((data, next) => {
        try {
            if (argName) {
                schema.parse(data.args[argName]);
            } else {
                schema.parse(data.args);
            }
        } catch (err: any) {
            throw new ArgumentValidationError(err);
        }

        return next();
    });
}

I looked it over when I was trying to handle BigInt values from a postgres DB (I ended up just creating my own custom scalar with new GraphQLScalarType though). I do like what they have noted about validations though. Have you tried it at all?

no about to give it a shot

I am late to the party when it comes to GraphQL but I have to say I am thoroughly impressed with it so far. Interested to hear how it goes for you
