Supabase and Next.js RevalidatePath: Unraveling the Mystery of the Uncooperative Duo

Are you tired of banging your head against the wall, trying to get Supabase and Next.js to play nice with revalidatePath? You’re not alone! Many developers have stumbled upon this frustrating issue, only to find themselves lost in a sea of confusing documentation and half-baked solutions. Fear not, dear reader, for today we embark on a quest to conquer this beast and emerge victorious.

What’s the Problem, Anyway?

The revalidatePath function in Next.js is a powerful tool that allows you to revalidate static pages at runtime, ensuring that your users always see the freshest data. However, when paired with Supabase, a popular PostgreSQL-based database, things can get a bit hairy. The issue arises when you try to use revalidatePath with Supabase’s Realtime API, which enables real-time data updates. The two technologies just don’t seem to get along, resulting in a big fat error message and a lot of frustration.

Understanding the Culprits: Supabase and Next.js

Before we dive into the solution, let’s take a moment to understand the two main players in this drama.

Supabase

Supabase is an amazing tool that provides a robust, scalable, and secure way to handle your application’s data. With its Realtime API, you can receive real-time updates on your data, making it perfect for applications that require instantaneous data synchronization. However, thisRealtime API relies on WebSockets, which can sometimes interfere with Next.js’s revalidatePath function.

Next.js

Next.js is a popular React-based framework for building server-rendered, statically generated, and performance-optimized applications. Its revalidatePath function is a powerful tool that allows you to revalidate static pages at runtime, ensuring that your users always see the freshest data. However, this function relies on the Next.js API routes, which can sometimes conflict with Supabase’s Realtime API.

The Solution: A Step-by-Step Guide

Now that we understand the problem and the players involved, let’s get down to business! Here’s a step-by-step guide to getting Supabase and Next.js revalidatePath working in harmony:

Step 1: Set up Supabase Realtime API

First, we need to set up the Supabase Realtime API. Create a new Supabase instance and enable the Realtime API. You can do this by following these steps:

• Go to your Supabase dashboard and create a new instance.
• Click on the ” Settings” icon (gear icon) in the bottom left corner.
• Scroll down to the “Realtime” section and toggle the switch to enable it.
• Note down the Realtime API URL, which should look something like wss://your-instance.supabase.io/realtime/v1.

Step 2: Configure Next.js API Routes

Next, we need to configure the Next.js API routes to work with the Supabase Realtime API. Create a new API route in your Next.js project, and add the following code:

import { NextApiRequest, NextApiResponse } from 'next';
import { createClient } from '@supabase/supabase-js';

const supabaseUrl = 'https://your-instance.supabase.io';
const supabaseKey = 'your-supabase-key';
const supabaseSecret = 'your-supabase-secret';
const realtimeUrl = 'wss://your-instance.supabase.io/realtime/v1';

const supabase = createClient(supabaseUrl, supabaseKey, supabaseSecret);

export default async function handler(req: NextApiRequest, res: NextApiResponse) {
  const { method, query } = req;

  if (method === 'GET') {
    const { data, error } = await supabase
      .from('your-table-name')
      .select('column1, column2')
      .eq('id', query.id);

    if (error) {
      return res.status(500).json({ error: 'Failed to retrieve data' });
    }

    return res.status(200).json(data);
  }

  return res.status(405).json({ error: 'Method not allowed' });
}

Replace the placeholders with your actual Supabase instance URL, key, secret, and table name.

Step 3: Implement revalidatePath with Supabase Realtime API

Now that we have our Supabase Realtime API set up and our Next.js API route configured, it’s time to implement revalidatePath. Create a new page in your Next.js project, and add the following code:

import { useQuery, useQueryClient } from 'react-query';
import { supabase } from '../api/supabase';

const useGetData = () => {
  const { data, error, isLoading } = useQuery(
    'data', // key
    async () => {
      const { data, error } = await supabase
        .from('your-table-name')
        .select('column1, column2')
        .eq('id', 'your-id');

      if (error) {
        throw error;
      }

      return data;
    }
  );

  return { data, error, isLoading };
};

const Page = () => {
  const { data, error, isLoading } = useGetData();
  const queryClient = useQueryClient();

  if (isLoading) {
    return 
Loading...
;
  }

  if (error) {
    return 
Error: {error.message}
;
  }

  return (
    

      
      
{data[0].column2}
       {
          await queryClient.revalidate('data');
        }}
      >
        Revalidate
      
    
  );
};

export default Page;

Replace the placeholders with your actual table name, column names, and ID.

Step 4: Handle Realtime Updates with Supabase

Finally, we need to handle real-time updates with Supabase. Create a new file in your Next.js project, and add the following code:

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

const supabaseUrl = 'https://your-instance.supabase.io';
const supabaseKey = 'your-supabase-key';
const supabaseSecret = 'your-supabase-secret';
const realtimeUrl = 'wss://your-instance.supabase.io/realtime/v1';

const supabase = createClient(supabaseUrl, supabaseKey, supabaseSecret);

supabase.realtime
  .from('your-table-name')
  .on('UPDATE', (payload) => {
    console.log('Realtime update:', payload);
    // Revalidate the page here
  })
  .subscribe();

Replace the placeholders with your actual Supabase instance URL, key, secret, and table name. This code sets up a Realtime API subscription to listen for updates on the specified table. When an update is detected, it logs the payload to the console and revalidates the page.

Conclusion

And there you have it! With these steps, you should now be able to use Supabase and Next.js revalidatePath together in harmony. Remember to replace the placeholders with your actual values, and don’t hesitate to reach out if you encounter any issues.
