Getting 404 error with @nestjs/websockets

Server :

import {
    ConnectedSocket,
    MessageBody,
    OnGatewayConnection, OnGatewayDisconnect, OnGatewayInit,
    SubscribeMessage,
    WebSocketGateway,
    WebSocketServer
} from '@nestjs/websockets';
import { Server, Socket } from 'socket.io';
import { Logger } from '@nestjs/common';

@WebSocketGateway()
export class ChatGateway implements OnGatewayInit, OnGatewayConnection, OnGatewayDisconnect {
    @WebSocketServer()
    server: Server;

    private logger: Logger = new Logger('AppGateway');

    @SubscribeMessage('msgToServer')
    handleMessage(client: Socket, payload: string): void {
        this.server.emit('msgToClient', payload);
    }

    afterInit(server: Server) {
        this.logger.log('Init');
    }

    handleDisconnect(client: Socket) {
        this.logger.log(`Client disconnected: ${client.id}`);
    }

    handleConnection(client: Socket, ...args: any[]) {
        this.logger.log(`Client connected: ${client.id}`);
    }
}

Client side:

import { SocketIoModule, SocketIoConfig } from 'ngx-socket-io';
const socketConfig: SocketIoConfig = {
    url: 'http://localhost:3000',
    options: {
        path: '/'
    }
};

Error

GET http://localhost:3000/?EIO=4&transport=polling&t=NhD2AKw 404 (Not Found)

Guys, make sure you’re hitting your nestjs server. If you use angular you might want to configure proxy like that:

{
  "/api": {
    "target": "http://localhost:3333",
    "secure": false
  },
  "/socket.io": {
    "target": "http://localhost:3333",
    "secure": false
  }
}
