A web application for searching your LinkedIn network using semantic search.

• Sign in with LinkedIn to access your network
• Index your LinkedIn connections for semantic search
• Search for people by skills, experience, or company
• View detailed profile information
• Expandable profile cards with summaries

This project is divided into two main parts:

• Frontend: Next.js application with TypeScript and Tailwind CSS
• Backend: FastAPI application with PostgreSQL and Pinecone for vector search

• Node.js 18+ and npm
• Python 3.9+
• PostgreSQL
• Pinecone account
• OpenAI API key
• LinkedIn Developer account

1. Navigate to the backend directory:

   cd backend

2. Create a virtual environment and activate it:

   python -m venv venv
   source venv/bin/activate  # On Windows: venv\Scripts\activate

3. Install dependencies:

   pip install -r requirements.txt

4. Copy .env.example to .env and fill in the required values:

   cp .env.example .env

5. Run the development server:

   uvicorn app.main:app --reload

1. Navigate to the frontend directory:

   cd frontend

2. Install dependencies:

   npm install

3. Copy .env.local.example to .env.local and fill in the required values:

   cp .env.local.example .env.local

4. Run the development server:

   npm run dev

1. Open your browser and navigate to http://localhost:3000
2. Sign in with your LinkedIn account
3. Wait for your network to be indexed
4. Search for people using natural language queries

• JWT Authentication

This application uses NextAuth.js for authentication with LinkedIn. The authentication flow is as follows:

1. User clicks "Sign in with LinkedIn" on the frontend
2. NextAuth.js redirects to LinkedIn's OAuth page
3. User authenticates with LinkedIn
4. LinkedIn redirects back to the NextAuth.js callback URL
5. NextAuth.js creates a session with the user's information and LinkedIn tokens
6. The frontend uses the session token for API authentication
7. The backend validates the NextAuth.js token and identifies the user

For authentication to work properly, you need to set up the following environment variables:

NEXTAUTH_URL=http://localhost:3000
NEXTAUTH_SECRET=your-nextauth-secret-for-development-only
LINKEDIN_CLIENT_ID=your-linkedin-client-id
LINKEDIN_CLIENT_SECRET=your-linkedin-client-secret

NEXTAUTH_SECRET=your-nextauth-secret-for-development-only

Important: The NEXTAUTH_SECRET must be the same in both the frontend and backend for token validation to work correctly.

In the LinkedIn Developer Portal, you need to configure the following:

1. Redirect URL: http://localhost:3000/api/auth/callback/linkedin
2. OAuth 2.0 scopes: r_emailaddress, r_liteprofile
