Email validation with Zod can be broken down into a few steps. Let’s walk through this process so you can see what it looks like. Step 1: Install Zod First of all, add Zod to your project. This typically requires running a command in your project's terminal. So open your project terminal and run the following command: npm install zod This command tells the package manager (npm) to download and add Zod to your project. Step 2: Import Zod into your file Once Zod is installed, you need to integrate it into the file where the validation will take place.
This is done using a simple import statement. At the beginning of the JavaScript file where you want to use Zod, add: import { z } from 'zod' ; This line imports the Zod library into your file and makes its functionality available. Step 3: Define the email validation schema Defining a schema lets you tell Zod what valid data should look like. At this point, you need to define a schema that specifies that you expect a string that matches the format of an email address. Zod has built-in functions that make this easy.
To define an email validation schema, add: g().email({ message: “Invalid email address” }); This code creates a new validation schema called emailSchema that expects a string in the proper email format. If the verification fails, it returns a custom error message that says "Invalid email address". Step 4: Test your schema It is a good idea to test your schema with a usa mobile numbers list few sample email addresses to make sure it works as expected. Try out both correct and incorrect email addresses to see the results. This step may take some trial and error, and if you have any difficulties, ask a developer for help. For example: pass the email address you want to check as an argument to a function provided by Zod.
If the email address does not match the pattern, Zod will produce the appropriate error message. To validate an email address, use the pattern as follows: try; // Replace with the email to validate console.log("Valid email"); } catch (error) { console.error(error.errors); // This will log the custom message if the email is invalid } This snippet attempts to validate the email " " against your emailSchema. If the email is legitimate, it prints "Valid Email" to the console. If not, it catches the error thrown by Zod and logs the correct information.
