Validate without Zod

validation() only needs a safeParse() method matching Zod's shape -- write your own if you don't want the dependency.

import { Maskea, validation, type ZodLikeSchema } from "@nopeatech/maskea";

interface Invoice { total: number; currency: string }

const InvoiceSchema: ZodLikeSchema<Invoice> = {
  safeParse(data: unknown) {
    const d = data as Invoice;
    if (typeof d?.total === "number" && typeof d?.currency === "string") {
      return { success: true, data: d };
    }
    return { success: false, error: "missing total or currency" };
  },
};

const maskea = new Maskea().use(validation({ schema: InvoiceSchema }));
