What is Supabase

Introduction

Supabase helps you build apps faster by giving you ready-to-use backend services like databases and user login.

You want to create a web or mobile app quickly without building backend from scratch.

You need a database that works well with your app and is easy to manage.

You want to add user sign-up and login features without complex coding.

You want to store and serve files like images or documents for your app.

You want real-time updates in your app, like chat messages or live data.

Syntax

Supabase

No special code syntax; Supabase is a cloud service you connect to using simple API calls or client libraries.

Supabase uses PostgreSQL database behind the scenes.

You interact with Supabase using easy-to-understand JavaScript or other language clients.

Examples

This example shows how to start using Supabase in a JavaScript app by creating a client connection.

Supabase

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

const supabase = createClient('https://xyzcompany.supabase.co', 'public-anon-key');

This fetches all rows from a table named 'todos' in your Supabase database.

Supabase

const { data, error } = await supabase.from('todos').select('*');

Sample Program

This code connects to a Supabase project and fetches all records from a 'users' table, then prints them.

Supabase

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

// Connect to Supabase project
const supabaseUrl = 'https://xyzcompany.supabase.co';
const supabaseKey = 'public-anon-key';
const supabase = createClient(supabaseUrl, supabaseKey);

// Fetch all users from 'users' table
async function fetchUsers() {
  const { data, error } = await supabase.from('users').select('*');
  if (error) {
    console.error('Error fetching users:', error.message);
  } else {
    console.log('Users:', data);
  }
}

fetchUsers();
