How to resend email confirmation in Supabase?

 

Step 1: Set up the Project Environment

 

Before you can resend an email confirmation in Supabase, make sure you have a project set up. If you haven't created one yet, go to the Supabase website and sign up or log in. Once logged in, create a new project from the dashboard. Remember to store the project's API URL and Anon key, as you'll need these for your application.

 

Step 2: Configure User Management

 

Navigate to the Authentication tab on your Supabase dashboard. Here, ensure that email signups are enabled, which allows users to register using their email addresses. Verify the SMTP settings so that Supabase can send out confirmation emails. You'll need to provide:

• SMTP Host
• SMTP Port
• SMTP Username
• SMTP Password
• Email sender name and address

This setup allows Supabase to send confirmation emails using the configured SMTP server.

 

Step 3: Create a Function to Resend Confirmation Email

 

You'll need to interact with Supabase using its JavaScript client to trigger the resend. Install the Supabase library in your project if you haven't already:

npm install @supabase/supabase-js

Next, you need to set up your client:

import { createClient } from '@supabase/supabase-js'

// These keys can be found on the project's settings page
const supabaseUrl = 'https://your-supabase-url.supabase.co'
const supabaseAnonKey = 'your-anon-key'

// Create a Supabase client
const supabase = createClient(supabaseUrl, supabaseAnonKey)

 

Step 4: Implement the Resend Confirmation Functionality

 

Define a function within your application to handle the process of resending the email confirmation. This function will call the appropriate Supabase function to trigger the email resend:

async function resendConfirmation(email) {
  try {
    const { error } = await supabase.auth.api.resendEmailConfirmation(email)
    if (error) throw error
    console.log('Confirmation email resent successfully.')
  } catch (error) {
    console.error('Error resending confirmation email:', error.message)
  }
}

 

Step 5: Create a User Interface for Users to Request Resend

 

Develop a simple UI to allow users to request that a confirmation email be resent to their email address. Here’s an example using plain HTML and JavaScript:

  


  
Resend Confirmation Email
  
  Resend Confirmation Email

  

 

Step 6: Test the Resend Functionality

 

To ensure everything is correctly configured, test the application by trying to resend a confirmation email to a user. Check whether the email arrives in your designated inbox. If the email doesn’t arrive, verify the SMTP settings and ensure that there aren’t any connection issues with the SMTP server.

 

Step 7: Deploy Your Application

 

Once you've tested locally, deploy your web application to a hosting service of your choice (e.g., Vercel, Netlify, etc.). Be sure to handle environment variables securely, especially your Supabase URL and Anon key.
