~1 hour Hands-on Precision AI Academy

Today’s Objective

Create a Supabase project, enable auth providers, and build sign-up/login/logout in a web app.

Supabase gives you: a PostgreSQL database, auth system, file storage, edge functions, and realtime subscriptions — from one dashboard. The free tier covers most projects.

Install
INSTALL
npm install @supabase/supabase-js
src/supabase.js
SRC/SUPABASE.JS
import { createClient } from '@supabase/supabase-js';

export const supabase = createClient( import.meta.env.VITE_SUPABASE_URL, import.meta.env.VITE_SUPABASE_ANON_KEY
);
Auth: Sign up, login, logout
AUTH: SIGN UP, LOGIN, LOGOUT
import { supabase } from './supabase';

// Email/password sign up
const { data, error } = await supabase.auth.signUp({ email: '[email protected]', password: 'securepassword'
});

// Login
const { data: { session } } = await supabase.auth.signInWithPassword({ email: '[email protected]', password: 'securepassword'
});

// OAuth (Google, GitHub)
await supabase.auth.signInWithOAuth({ provider: 'google', options: { redirectTo: window.location.origin }
});

// Logout
await supabase.auth.signOut();

// Get current user
const { data: { user } } = await supabase.auth.getUser();

// Listen to auth changes
supabase.auth.onAuthStateChange((event, session) => { console.log(event, session?.user);
});
