Just the client half — a JavaScript library that you embed in your own app to talk to a Socket.IO server, which is a separate part of the project.How do I add it to a project?Install it from npm: npm install socket.io-client. Then point the client at your Socket.IO server's URL to open the connection.

Then point the client at your Socket.IO server's URL to open the connection.Does the client work on its own, or do I need a server too?You need a Socket.IO server to connect to — it ships as its own package (socket.io) that runs on Node.js; without one the client has nothing to exchange events with.
