Setting up a socket server
Setting up the socket server done by the
socketService.init method: socketService.init(serverInstance:http.Server|express.Application,
namespace:string ="/",
socketConfig?:socketOptions,
connectionCallback?:(socket)=>void,
disconnectCallback?:(socket)=>void
):SocketIOStatic.Server;
socketService.init(portNumber:number,
namespace:string ="/",
socketConfig?:socketOptions,
connectionCallback?:(socket)=>void,
disconnectCallback?:(socket)=>void
):SocketIOStatic.Server;
import {SocketHandler} from "@sugoi/socket";
// serverInstance is server instance (sugoijs, express, koa, nodejs http etc.)
// in case you are using @socket\server, the instance returns from the 'listen' method
// signature - init(HttpServer: any, socketConfig: SocketIOStatic.ServerOptions, namespace: string): SocketIOStatic.Server
const SocketHandler = socketService.init(serverInstance);
Server module provide the ability to initiate services on the module initialization. Since socketServer is depended on the initialized http server instance we can delay it creation by using factory, this will be done by intercept the init method with an arrow function.
import {SocketHandler} from "@sugoi/socket";
import {serverInstance} from "../app";
@ServerModule({
services: [{
provide: () => SocketHandler.init(serverInstance),
useName: "SocketServer"
}]
})
export class BoostrapModule{
constructor(@Inject("SocketServer") private _socketServer){}
}
serverInstance = The server instance the socket server should be attached to.
socketConfig?:socketOptions - The socket server configurations with the same interface as on socket.io documentation socketOptions:{
path: string,
serveClient: boolean,
adapter:Adapter,
origins:string,
parser:Parser
}
namespace:string- The socket server namespace to bind to, allow to assign different endpoint to the socket server, more info on socket.io documentation.The returned value of the
SocketHandler.init method is the socket server instance (SocketIOStatic.Server).
