nest-udp-adapter

A Nest UDP adapter based on @nestjs/websockets

Installation

To begin using it, we first install the required dependency.

$ npm install --save @nestjs/websockets nest-udp-adapter 

Getting started

Once the installation is complete, we can set up UDP adapter using useWebSocketAdapter() method:

const app = await NestFactory.create(AppModule);
app.useWebSocketAdapter(new UdpAdapter(app, {
  type: 'udp4',
  port: 41234,
}));

The second argument of the UdpAdapter constructor is an options object. This object may consist of seven members:

type	Either udp4 or udp6 (default: udp4)
port	Destination port
address	Destination host name or IP address
socketOptions	dgram.SocketOptions (read more here)
bindOptions	dgram.BindOptions (read more here)
multicastAddress	The IP multicast group address
multicastInterface	The local IP address associated with a network interface

Example
