Lovable Boilerplate

Reverse-engineered Lovable AI app builder turned into a developer-friendly React boilerplate with comprehensive AI coding assistant instructions.

One-Click Setup

What is this?

This boilerplate reverse-engineers the magic behind Lovable's no-code AI app builder into a traditional React codebase that developers can understand, modify, and extend. It bridges the gap between no-code AI generation and developer control.

Installation

# Clone the repository
git clone https://github.com/chihebnabil/lovable-boilerplate.git
cd lovable-boilerplate

# Install dependencies (npm, yarn, or bun)
npm install
# or
bun install

# Set up environment variables
cp .env.example .env
# Edit .env with your Supabase credentials

# Start development server
npm run dev
# or
bun dev

Your app will be running at http://localhost:8080

Supabase Integration

This boilerplate comes with Supabase pre-configured for backend functionality including authentication, database, and real-time features.

Setup Supabase

1. Create a Supabase Project

   • Visit supabase.com and create a new project
   • Wait for your database to be provisioned

2. Configure Environment Variables

   cp .env.example .env
   

   Add your Supabase credentials to .env:

   VITE_SUPABASE_URL=https://your-project.supabase.co
   VITE_SUPABASE_PUBLISHABLE_KEY=your-anon-key
   

Using Supabase in Your App

// Import the Supabase client
import { supabase } from "@/integrations/supabase/client";
import type { Tables } from "@/integrations/supabase/types";

// Example: Fetch data
const { data, error } = await supabase
  .from('posts')
  .select('*')
  .eq('published', true);

// Example: Insert data
const { data, error } = await supabase
  .from('posts')
  .insert({
    title: 'My Post',
    slug: 'my-post',
    content: 'Post content',
    user_id: userId
  });

// Example: Real-time subscription
supabase
  .channel('posts')
  .on('postgres_changes', 
    { event: '*', schema: 'public', table: 'posts' },
    (payload) => {
      console.log('Change received!', payload);
    }
  )
  .subscribe();

Type Safety

All database types are automatically generated in src/integrations/supabase/types.ts:

import type { Tables, TablesInsert, TablesUpdate } from "@/integrations/supabase/types";

// Use generated types
type Post = Tables<'posts'>;
type NewPost = TablesInsert<'posts'>;
type UpdatePost = TablesUpdate<'posts'>;

Authentication Example

// Sign up
const { data, error } = await supabase.auth.signUp({
  email: 'user@example.com',
  password: 'password'
});

// Sign in
const { data, error } = await supabase.auth.signInWithPassword({
  email: 'user@example.com',
  password: 'password'
});

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

// Sign out
await supabase.auth.signOut();

Best Practices

• Environment Variables: Never commit .env files. Use .env.example as a template
• Row Level Security: Enable RLS on your Supabase tables for security
• Type Generation: Regenerate types when your database schema changes
• Error Handling: Always handle errors from Supabase operations
• Real-time: Use Supabase real-time for live updates without polling

Local Development with Supabase CLI

The boilerplate includes Supabase CLI configuration for local development:

# Initialize Supabase (already done)
npx supabase init

# Start Supabase locally (requires Docker)
npx supabase start

# Stop local Supabase
npx supabase stop

# Generate TypeScript types from your database
npx supabase gen types typescript --local > src/integrations/supabase/types.ts

# Create a new migration
npx supabase migration new migration_name

# Push migrations to remote database
npx supabase db push

The supabase/ folder contains:

• config.toml: Supabase CLI configuration
• migrations/: Database migration files (version-controlled SQL)
• .gitignore: Excludes temporary files from version control
