Is it possible to create a TCP server using NestJS??
I have a GPS tracker that communicate only with TCP. As NestJS could communicate between microservices with TCP, I thought that maybe NestJS could be used as low level network applications (something like java-netty/python-tornado)
You could easily add a TCP server service as a provider for your NestJs module.
You can test it by "telnet 127.0.0.1 1337"
import { Module } from '@nestjs/common';
import { AppController } from './app.controller';
import { AppService } from './app.service';
import * as net from 'net';
@Module({
imports: [],
controllers: [AppController],
providers: [
AppService,
{
provide: 'TcpServerService',
useFactory: () => {
const server = net.createServer(socket => {
socket.write('\r\rFrom NestJs TcpServerService\r\n');
socket.pipe(socket);
});
server.listen(1337, '127.0.0.1');
return server;
},
},
],
})
export class AppModule {}
