How can I perform discriminated union validations with Elysia’s built-in validator?

[Mateusvaz89]

Hello,

I’m currently working with Elysia and trying to implement a validation similar to the following discriminated union example using Zod:

const schema = z.discriminatedUnion("paymentMethod", [
z.object({
paymentMethod: z.literal("creditCard"),
card: z.object({
number: z.string(),
holderName: z.string(),
expirationDate: z.string(),
securityCode: z.string(),
}),
}),
z.object({
paymentMethod: z.literal("coupon"),
couponCode: z.string(),
}),
]);

My goal is to achieve the same type of validation using Elysia’s default validator. However, I’m unsure how to translate this discriminated union logic into the built-in validation system provided by Elysia.

Could someone please guide me on how to implement this? Any examples or documentation pointers would be greatly appreciated.

Thank you in advance!
