Pococare

Pococare's video consultancy with doctors feature provides users with convenient and accessible virtual medical consultations. With this feature, users can connect with healthcare professionals through secure video calls for personalized healthcare advice and guidance.

Important Note: Video Call Functionality Limitations

• Video call functionality is currently limited in the deployed version. For the best experience, clone the repository and run the application locally.

• Why is it not working? Hosting service providers allow only one server on a specific port, preventing seamless peer-to-peer connections. Thus, only one person's video will be rendered in the deployed version.

• How to make it work perfectly and make communication between doctors and patients

Clone the repository.

git clone https://github.com/manoj7654/doctor_patient_appointment_booking.git

• Install dependencies:

   cd backend & npm install.
  

• Start Node.js server: npm run server.

• Start Peer server on a separate port: peerjs --port 3001.

• Access the application locally:

     http://localhost: <your-port>
  

• By running the application locally, you ensure separate ports for the Node.js and Peer servers, enabling successful peer-to-peer video communication.
