Supabase Auth Invalid Email Format

The email address provided does not follow a valid format.

Understanding Supabase Auth

Supabase Auth is a powerful authentication provider that simplifies the process of adding authentication to your applications. It offers a range of features, including email/password authentication, social logins, and more, making it a versatile choice for developers looking to secure their applications efficiently.

Identifying the Symptom: Invalid Email Format

When using Supabase Auth, you might encounter an error related to an invalid email format. This issue typically arises when a user attempts to register or log in with an email address that does not adhere to standard email formatting rules.

What You Might Observe

Users may receive an error message stating that the email address provided is invalid. This can prevent them from completing the registration or login process, leading to a poor user experience.

Exploring the Issue: Invalid Email Format

The root cause of this issue is straightforward: the email address entered by the user does not conform to the expected format. A valid email address should follow the pattern [email protected], including a username, the '@' symbol, and a domain.

Common Mistakes

  • Missing '@' symbol
  • Missing domain part
  • Extra spaces or invalid characters

Steps to Fix the Invalid Email Format Issue

To resolve this issue, you can implement a few straightforward steps to ensure that users enter correctly formatted email addresses.

1. Validate Email Format on the Client-Side

Implement client-side validation using JavaScript to check the email format before submission. This can prevent invalid entries from reaching your server.

function validateEmail(email) {
const re = /^[\w-\.]+@([\w-]+\.)+[\w-]{2,4}$/;
return re.test(email);
}

2. Provide User Feedback

Prompt users with a clear message if their email format is incorrect. This can be done using HTML5 form validation attributes or custom JavaScript alerts.

<input type="email" required placeholder="Enter your email">

3. Server-Side Validation

Always validate the email format on the server-side as well to ensure data integrity. This acts as a second line of defense against malformed inputs.
