Examples

When to use this page

All examples live at _examples/. Each is self-contained — cd into the directory and go run.

Example	What it shows
basic	Minimal echo server + Go client + browser client. Start here.
example	Interactive chat-style demo: connect, join a room, exchange messages, leave.
browser	Vanilla browser client paired with a Go server.
native-messages	Raw WebSocket frames — no neffos wire format. Useful for interop with non-neffos clients.
protobuf	Binary protocol using Protocol Buffers for `Message.Body`.
struct-handler	Methods on a Go struct used as event handlers via `neffos.NewStruct`.
wrap-conns-to-user	Attach a user record to each `Conn` via `Conn.Set("user", u)` for auth-aware events.
cronjob	Server-side scheduled tasks that broadcast over neffos.
scale-out	Multi-instance neffos with Redis and NATS. Pair with [[Scale out
stress-test	Synthetic load — server, client, and broadcast variants.

git clone https://github.com/kataras/neffos
cd neffos/_examples/basic
go run echo.go server   # in one terminal
go run echo.go client   # in another

Most server examples bind to :8080. The matching browser examples have a small index.html you can open after starting the server.

Browser and Node samples for the neffos.js TypeScript client live in neffos.js/_examples.
