Express.js socket handler

This package is an easy way to implement and manage socket connections and also make a simple way to migrate from REST API to Socket API.

Installation instruction:

npm install node-express-socket

Use:

Important: It only can use by Router and you can't use by express() method like as express().socket

Server side:

const express = require('express');
const socket = require("node-express-socket");
const router = express.Router();
const app = express();

router.socket("/test1/:fname/:lname", (req, res) => {
  res.send({m:req.method, q:req.query, b:req.body, p:req.params});
});

router.get("/test1/:fname/:lname", (req, res) => {
  res.send({m:req.method, q:req.query, b:req.body, p:req.params});
});

const server = app.listen(8000, () => {
  console.log(`Server running at port:8000`);
});

app.use(socket(app, server));
app.use(router);

If you want to use a general route for 'Not found', it should be after socket use command.

Get user socket id

Send message to specific user

Send broadcast message

Response socket message from out of socket methods

Client side:

// 1) Create and connect socket object
const socket = io();

// 2) Send request using WebSocket
socket.emit('/test1/joe/gandomi?qp1=v1', {
    var1: "value1",
    var2: "value2"
});

// 3) Receive response using WebSocket
socket.on('/test/*/*', data => {
  console.log(data);
});

Client log:

{
    m: "SOCKET",
    q: {
        qp1: "v1"
    },
    p: {
        fname: "joe",
        lname: "gandomi"
    },
    b: {
        var1: "value1",
        var2: "value2"
    }
}
