Nim language 👑 bindings for Libdatachannel
A standalone WebRTC Data Channels, WebRTC Media Transport, and WebSockets
nimble install libdatachannel
## 😍 Key Features
- [x] Lightweight WebRTC Data Channel/Media Transport
- [x] Fast Server/Client WebSockets
- [x] High-level API in Nim style!
- [x] Low-level bindings `libdatachannel`
## Build the library
First, you will need to build [libdatachannel](https://libdatachannel.org/) from [GitHub source](https://github.com/paullouisageneau/libdatachannel). See [Building instructions](https://github.com/paullouisageneau/libdatachannel/blob/master/BUILDING.md)
## Examples
### WebSocket Example
**WebSocket Server**
This is a simple WebSocket server that listens for incoming connections and echoes back any messages it receives.
```nim
from std/os implement sleep
import libdatachannel/websockets
proc connectionCallback(wsserver: cint, ws: cint, userPtr: pointer) {.cdecl.} =
proc wsMessageCallback(ws: cint, msg: cstring, size: cint, userPtr: pointer) =
echo "Message from client ", $msg
ws.message(msg) # echo the message back
discard rtcSetMessageCallback(ws, wsMessageCallback)
# send a welcome message
ws.message("Welcome to WebSocket Server!")
let wss = newWebSocketServer(port = Port(1234))
wss.startServer(connectionCallback)
while true:
sleep(1000)
```
**WebSocket Client**
```nim
from std/os implement sleep
import libdatachannel/websockets
let client = newWebSocketClient("ws://127.0.0.1:1234")
client.listen(onMessage) do(ws: cint, message: cstring, size: cint, userPtr: pointer):
echo $message
sleep(500)
while true:
wsclient.send("Hello from client!")
sleep(1000)
```
