### Websockets
|
||||
|
||||
iris websocket library lives on its own [package](https://github.com/kataras/iris/tree/master/websocket) which depends on the [kataras/neffos](https://github.com/kataras/neffos) external package.
|
||||
[WebSocket](https://wikipedia.org/wiki/WebSocket) is a protocol that enables two-way persistent communication channels over TCP connections. It is used for applications such as chat, stock tickers, games, anywhere you want real-time functionality in a web application.
|
||||
|
||||
Iris websocket library is now merged with the [neffos real-time framework](https://github.com/kataras/neffos) and Iris-specific helpers live on the [iris/websocket](https://github.com/kataras/iris/tree/master/websocket) subpackage. Learn neffos from its [wiki](https://github.com/kataras/neffos#learning-neffos) and have a look some of the [Iris websocket examples](websocket/).
|
||||
|
||||
The package is designed to work with raw websockets although its API is similar to the famous [socket.io](https://socket.io). I have read an article recently and I felt very contented about my decision to design a **fast** websocket-**only** package for Iris and not a backwards socket.io-like package. You can read that article by following this link: https://medium.com/@ivanderbyl/why-you-don-t-need-socket-io-6848f1c871cd.

# Websocket
|
||||
|
||||
[WebSocket](https://wikipedia.org/wiki/WebSocket) is a protocol that enables two-way persistent communication channels over TCP connections. It is used for applications such as chat, stock tickers, games, anywhere you want real-time functionality in a web application.
|
||||
|
||||
[View or download sample code](https://github.com/kataras/iris/tree/master/_examples/websocket).
|
||||
|
||||
## When to use it
|
||||
|
||||
Use WebSockets when you need to work directly with a socket connection. For example, you might need the best possible performance for a real-time game.
|
||||
|
||||
## How to use it
|
||||
|
||||
* import the `"github.com/kataras/iris/websocket"`
|
||||
* Configure the websocket package.
|
||||
* Accept WebSocket requests.
|
||||
* Send and receive messages.
|
||||
|
||||
### Import the websocket package
|
||||
|
||||
```go
|
||||
import "github.com/kataras/iris/websocket"
|
||||
```
|
||||
|
||||
### Configure the websocket package
|
||||
|
||||
```go
|
||||
import "github.com/kataras/iris/websocket"
|
||||
|
||||
func main() {
|
||||
ws := websocket.New(websocket.Config{
|
||||
ReadBufferSize: 1024,
|
||||
WriteBufferSize: 1024,
|
||||
})
|
||||
}
|
||||
```
|
||||
|
||||
#### Complete configuration
|
||||
|
||||
```go
|
||||
// Config the websocket server configuration
|
||||
// all of these are optional.
|
||||
type Config struct {
|
||||
// IDGenerator used to create (and later on, set)
|
||||
// an ID for each incoming websocket connections (clients).
|
||||
// The request is an argument which you can use to generate the ID (from headers for example).
|
||||
// If empty then the ID is generated by DefaultIDGenerator: randomString(64)
|
||||
IDGenerator func(ctx context.Context) string
|
||||
// Error is the function that will be fired if any client couldn't upgrade the HTTP connection
|
||||
// to a websocket connection, a handshake error.
|
||||
Error func(w http.ResponseWriter, r *http.Request, status int, reason error)
|
||||
// CheckOrigin a function that is called right before the handshake,
|
||||
// if returns false then that client is not allowed to connect with the websocket server.
|
||||
CheckOrigin func(r *http.Request) bool
|
||||
// HandshakeTimeout specifies the duration for the handshake to complete.
|
||||
HandshakeTimeout time.Duration
|
||||
// WriteTimeout time allowed to write a message to the connection.
|
||||
// 0 means no timeout.
|
||||
// Default value is 0
|
||||
WriteTimeout time.Duration
|
||||
// ReadTimeout time allowed to read a message from the connection.
|
||||
// 0 means no timeout.
|
||||
// Default value is 0
|
||||
ReadTimeout time.Duration
|
||||
// PongTimeout allowed to read the next pong message from the connection.
|
||||
// Default value is 60 * time.Second
|
||||
PongTimeout time.Duration
|
||||
// PingPeriod send ping messages to the connection with this period. Must be less than PongTimeout.
|
||||
// Default value is 60 *time.Second
|
||||
PingPeriod time.Duration
|
||||
// MaxMessageSize max message size allowed from connection.
|
||||
// Default value is 1024
|
||||
MaxMessageSize int64
|
||||
// BinaryMessages set it to true in order to denotes binary data messages instead of utf-8 text
|
||||
// compatible if you wanna use the Connection's EmitMessage to send a custom binary data to the client, like a native server-client communication.
|
||||
// defaults to false
|
||||
BinaryMessages bool
|
||||
// ReadBufferSize is the buffer size for the underline reader
|
||||
// Default value is 4096
|
||||
ReadBufferSize int
|
||||
// WriteBufferSize is the buffer size for the underline writer
|
||||
// Default value is 4096
|
||||
WriteBufferSize int
|
||||
// EnableCompression specify if the server should attempt to negotiate per
|
||||
// message compression (RFC 7692). Setting this value to true does not
|
||||
// guarantee that compression will be supported. Currently only "no context
|
||||
// takeover" modes are supported.
|
||||
EnableCompression bool
|
||||
|
||||
// Subprotocols specifies the server's supported protocols in order of
|
||||
// preference. If this field is set, then the Upgrade method negotiates a
|
||||
// subprotocol by selecting the first match in this list with a protocol
|
||||
// requested by the client.
|
||||
Subprotocols []string
|
||||
}

1. Run your server through `https://` (`iris.Run(iris.TLS)` or `iris.Run(iris.AutoTLS)` or a custom `iris.Listener(...)`)
|
||||
2. Nothing changes inside the whole app, including the websocket side
|
||||
3. The clients must dial the websocket server endpoint (i.e `/echo`) via `wss://` prefix (instead of the non-secure `ws://`), for example `wss://example.com/echo`
