Create a .env.local file in the project root:

# Supabase Configuration
NEXT_PUBLIC_SUPABASE_URL=your_supabase_project_url
NEXT_PUBLIC_SUPABASE_ANON_KEY=your_supabase_anon_key

# Groq API Configuration

This project uses Supabase as its database backend. You need to create the following table in your Supabase project's SQL editor:

CREATE TABLE notes (
    id UUID DEFAULT gen_random_uuid() PRIMARY KEY,
    title TEXT NOT NULL,
    content TEXT,
    is_code BOOLEAN DEFAULT false,
    language TEXT,
    created_at TIMESTAMPTZ DEFAULT NOW(),
    updated_at TIMESTAMPTZ DEFAULT NOW(),
    user_id UUID NOT NULL REFERENCES auth.users(id) ON DELETE CASCADE,
    is_public BOOLEAN DEFAULT false,
    summary TEXT,
    tags TEXT[]
);

-- Enable Row Level Security
ALTER TABLE notes ENABLE ROW LEVEL SECURITY;

-- Create policies
CREATE POLICY "Users can view their own notes"
    ON notes FOR SELECT
    USING (auth.uid() = user_id);

CREATE POLICY "Users can insert their own notes"
    ON notes FOR INSERT
    WITH CHECK (auth.uid() = user_id);

CREATE POLICY "Users can update their own notes"
    ON notes FOR UPDATE
    USING (auth.uid() = user_id);

CREATE POLICY "Users can delete their own notes"
    ON notes FOR DELETE
    USING (auth.uid() = user_id);
