⚙️ Setup Instructions

Follow these steps to set up and run the application locally:

1. Clone the repository:

   git clone [https://github.com/moshe19909090/typesense-search-app.git](https://github.com/moshe19909090/typesense-search-app.git)
   cd typesense-search-app

2. Start Typesense using Docker: Navigate into the backend directory and run the Docker command. This will start a Typesense instance accessible on port 8108.

   cd backend
   docker run -p 8108:8108 -v$(pwd)/typesense-data:/data typesense/typesense:0.25.1 \
     --data-dir /data --api-key=xyz --listen-port 8108 --enable-cors

3. Install backend dependencies:

   npm install

4. Index product data: Run the indexing script to upload the sample catalog.fixed.jsonl data into your running Typesense instance. You should see logs confirming successful indexing.

   npm run index

5. Run the backend server:

   npm run dev

   This will start the Express server, which provides the /search endpoint for the frontend.

💻 Running the Frontend

Once the backend and Typesense are running, you can start the React frontend:

1. Open a new terminal and navigate to the frontend directory:

   cd frontend

2. Install frontend dependencies:

   npm install

3. Run the React application:

   npm start

   The application will open in your browser at http://localhost:3000.
