# Using Websockets
|
|
|
|
Using Websockets is super easy! By nature Websockets are a bit different than standard Http Request/Response lifecycle.
|
|
|
|
You can easily create a websocket handler which matches the route of `ws://host:port/route. You can create more than 1 websocket handler
|
|
with different routes.
|
|
|
|
```ruby
|
|
ws "/" do |socket|
|
|
|
|
end
|
|
|
|
ws "/route2" do |socket|
|
|
|
|
end
|
|
```
|
|
|
|
Let's access the socket and create a simple echo server.
|
|
|
|
```ruby
|
|
# Matches "/"
|
|
ws "/" do |socket|
|
|
# Send welcome message to the client
|
|
socket.send "Hello from Kemal!"
|
|
|
|
# Handle incoming message and echo back to the client
|
|
socket.on_message do |message|
|
|
socket.send "Echo back from server #{message}"
|
|
end
|
|
|
|
# Executes when the client is disconnected. You can do the cleaning up here.
|
|
socket.on_close do
|
|
puts "Closing socket"
|
|
end
|
|
end
|
|
```
