@dymo-api/zod

Official Dymo API Library for Zod

This library extends Zod with Dymo API validators for emails, IPs, phones, passwords, and more. You can see the original library documentation here.

Installation

Install the library in your project:

npm i @dymo-api/zod

# or

pnpm i @dymo-api/zod

# or

yarn add @dymo-api/zod

Authenticating the Client with API Key

Get your free API Key

import DymoAPIZod from "@dymo-api/zod";

const dymoClient = new DymoAPIZod({
   apiKey: "PRIVATE_TOKEN_HERE"
});

Validating Email Using Zod Schema

With @dymo-api/zod, your email validation can now be used directly in a Zod object, including async validation with automatic normalization:

import { z } from "zod";
import DymoAPIZod from "@dymo-api/zod";

const dymoClient = new DymoAPIZod({ apiKey: "PRIVATE_TOKEN_HERE" });

const userSchema = z.object({
    email: dymoClient.emailSchema(),  // Dymo API validation + normalization
    username: z.string().min(3),
    age: z.number().int().min(0)
});

(async () => {
    const userData = {
        email: "[e-mail]",
        username: "build",
        age: 10
    };

    const validatedUser = await userSchema.parseAsync(userData);

    console.log(validatedUser);
    /*
    {
      email: "[e-mail]", // normalized by Dymo API
      username: "build",
      age: 10
    }
    */
})();

Handling Invalid Emails

The schema will automatically throw an error if the email is considered fraudulent or invalid:

try {
    await userSchema.parseAsync({
        email: "[e-mail]",
        username: "build",
        age: 10
    });
} catch (err) {
    console.error("Validation failed:", err.errors);
    /*
    [
        { path: ["email"], message: "Invalid email" }
    ]
    */
}

Async Validation Functions (Optional)

If you prefer not to use Zod, you can validate emails directly with async functions:

const result = await dymoClient.validateEmail("[e-mail]");

if (!result.allow) {
    console.error("Email rejected by Dymo API:", result.reasons);
}

Combining with Other Validators

You can also create schemas for IPs, phones, and passwords:

const userSchema = z.object({
    email: dymoClient.emailSchema(),
    ip: dymoClient.ipSchema(),
    phone: dymoClient.phoneSchema(),

    // Coming Soon.
    password: dymoClient.passwordSchema()
});

[!IMPORTANT] All async validators require parseAsync() because they query the Dymo API.

💡 Tip: Using DymoAPIZod with Zod allows you to combine real-time fraud checks with normal Zod validations in a single schema.
