Next.js optimizes your web application for performance by automatically handling code splitting and lazy loading. This, combined with Supabase's real-time data updates, ensures a smooth and responsive user experience.

Rapid Development

The combination of Supabase and Next.js allows for rapid development. You can focus on building features and functionality instead of spending time on complex backend setups.

CRUD Operations in Next.js with Supabase:

Below are code snippets demonstrating CRUD (Create, Read, Update, Delete) operations using Supabase and Next.js:

Create a Record:

import { supabase } from '../utils/supabase';

async function createRecord(data) {
  const { data: newRecord, error } = await supabase
    .from('your_table_name')
    .insert([data]);

  if (error) {
    throw error;
  }

  return newRecord;
}

Read Records

import { supabase } from '../utils/supabase';

async function fetchRecords() {
  const { data, error } = await supabase
    .from('your_table_name')
    .select('*');

  if (error) {
    throw error;
  }

  return data;
}

Update a Record

import { supabase } from '../utils/supabase';

async function updateRecord(id, newData) {
  const { data, error } = await supabase
    .from('your_table_name')
    .update(newData)
    .eq('id', id);

  if (error) {
    throw error;
  }

  return data;
}

Delete a Record

import { supabase } from '../utils/supabase';

async function deleteRecord(id) {
  const { error } = await supabase
    .from('your_table_name')
    .delete()
    .eq('id', id);

  if (error) {
    throw error;
  }
}

Initialization of Supabase

First, make sure you have the Supabase JavaScript library installed (@supabase/supabase-js) using npm or yarn:

npm install @supabase/supabase-js
# or
yarn add @supabase/supabase-js

Now, create a supabase.js file in your utils folder:

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

// Initialize Supabase
const supabaseUrl = 'YOUR_SUPABASE_URL';
const supabaseKey = 'YOUR_SUPABASE_API_KEY';

export const supabase = createClient(supabaseUrl, supabaseKey);

UI Code for CRUD Operations in Next.js

Here's a basic example of how you can create a simple UI for CRUD operations in a Next.js application:

import { useEffect, useState } from 'react';
import { supabase } from '../utils/supabase';

export default function Home() {
  const [data, setData] = useState([]);
  const [newItem, setNewItem] = useState('');

  useEffect(() => {
    fetchRecords();
  }, []);

  const fetchRecords = async () => {
    try {
      const { data: records, error } = await supabase
        .from('your_table_name')
        .select('*');

      if (error) {
        throw error;
      }

      setData(records);
    } catch (error) {
      console.error('Error fetching records:', error);
    }
  };

  const createRecord = async () => {
    try {
      const { data: newRecord, error } = await supabase
        .from('your_table_name')
        .insert([{ column_name: newItem }]);

      if (error) {
        throw error;
      }

      setData([...data, newRecord[0]]);
      setNewItem('');
    } catch (error) {
      console.error('Error creating record:', error);
    }
  };

  const deleteRecord = async (id) => {
  try {
    const { error } = await supabase
      .from('your_table_name')
      .delete()
      .eq('id', id);

    if (error) {
      throw error;
    }

    setData(data.filter((item) => item.id !== id));
  } catch (error) {
    console.error('Error deleting record:', error);
  }
};


  return (
     <div>
    <h1>CRUD Operations</h1>
    <input
      type="text"
      placeholder="New Item"
      value={newItem}
      onChange={(e) => setNewItem(e.target.value)}
    />
    <button onClick={createRecord}>Create</button>
    <ul>
      {data.map((item) => (
        <li key={item.id}>
          {item.column_name}
          <button onClick={() => deleteRecord(item.id)}>Delete</button>
        </li>
      ))}
    </ul>
  </div>
  );
}
