Austen is an AI-powered Nextjs application to generate story relationships between book characters using Mermaidjs diagrams.

• 📚 Search and analyze any book from Open Library
• 🤖 AI-powered character relationship analysis
• 📊 Generate Mermaid diagrams
• 💾 Save, download (SVG, PNG) and manage your generated graphs
• 🌐 Share graphs publicly or keep them private
• 🔍 Discover public graphs generated by other users
• 👤 User accounts

A character relationship graph generated for "Sense and Sensibility" by Jane Austen:

1. Clone the repository:

   git clone https://github.com/herol3oy/austen.gitcd austen

2. Install dependencies:

   npm i

3. Set up environment variables:

   • Copy.env.local.example to.env.local
   • Fill in the required API keys:

     DEEPSEEK_API_KEY=your_deepseek_api_keyNEXT_PUBLIC_SUPABASE_URL=your_supabase_urlNEXT_PUBLIC_SUPABASE_ANON_KEY=your_supabase_anon_key

4. Set up Supabase:

   • Create a new Supabase project

   • Enable authentication

   • Run the following SQL statements in your Supabase SQL editor to create thegraphs andprofiles tables:

     createtablepublic.graphs (  id uuidnot null,  book_nametextnot null,  svg_graphtextnot null,  mermaid_syntaxtextnot null,  created_attimestamp with time zonenot null default now(),  author_nametextnull,  emojistextnull,  user_id uuidnull,  is_publicbooleannull default false,constraint graphs_pkeyprimary key (id),constraint graphs_user_id_fkeyforeign KEY (user_id)referencesauth.users (id)) TABLESPACE pg_default;createtablepublic.profiles (  id uuidnot null,  usernametextnot null,  updated_attimestamp with time zonenull default now(),constraint profiles_pkeyprimary key (id),constraint profiles_username_key unique (username),constraint profiles_id_fkeyforeign KEY (id)referencesauth.users (id)on delete CASCADE,constraint username_formatcheck ((username ~'^[a-zA-Z0-9_]+$'::text)),constraint username_lengthcheck (    (      (char_length(username)>=3)and (char_length(username)<=20)    )  )) TABLESPACE pg_default;

   • Set up Row Level Security (RLS) for both tables (see Supabase dashboard for examples on restricting access based onuser_id oris_public status).

   • Create a Supabase database functionhandle_new_user and a trigger onauth.users to automatically create a profile entry when a new user signs up. The function should extract the username fromNEW.raw_user_meta_data ->> 'username'.

     -- Function to create a profile for a new usercreatefunctionpublic.handle_new_user()returns triggerlanguage plpgsqlsecurity definerset search_path= publicas $$begininsert intopublic.profiles (id, username)values (new.id,new.raw_user_meta_data->>'username');  return new;end;$$-- Trigger to call the function after a new user is createdcreatetriggeron_auth_user_created  after insertonauth.users  for each row execute procedurepublic.handle_new_user();

5. Start the development server:

   npm run dev

6. Build for production:

   npm run build

• Implement Like/Unlike Functionality for Graphs

  • Add like button
  • Implement like/unlike API endpoints in Supabase
  • Add like count display

• Load more graphs in the discover page

  • Add a button to load more graphs
