I am about to implement real-time notification system in my project with the help of Socket.IO . So I am looking for some great advice from Expert how I can implement it more efficient way. I am using NextJS at my front-end.How can I send notification to specific person when somebody react on their post, like (like, comment etc) ? Should I emit event to that specific socket.id where post owner belongs to ? I dont understand how can I implement such thing. Please advice.
