# Text Streams
|
|
|
|
WebSockets have separate text and [binary](binary-stream.md) data flows.
|
|
|
|
Sending text input to a WebSocket sends it to the remote. Listening for text on a WebSocket receives text data from clients.
|
|
|
|
## Sending strings
|
|
|
|
Sending a `String` using a WebSocket sends it to the remote.
|
|
|
|
```swift
|
|
webSocket.send(string)
|
|
```
|
|
|
|
## Receiving strings
|
|
|
|
String data can be read using the following function. Only one closure can read at a time.
|
|
|
|
```swift
|
|
webSocket.onText { text in
|
|
// use the `String`
|
|
}
|
|
```
